+
+Board-Specific Configurations
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The NuttX configuration consists of:
+
+o Processor architecture specific files.  These are the files contained
+  in the arch/<arch-name>/ directory.
+
+o Chip/SoC specific files.  Each processor processor architecture
+  is embedded in chip or System-on-a-Chip (SoC) architecture.  The
+  full chip architecture includes the processor architecture plus
+  chip-specific interrupt logic, general purpose I/O (GIO) logic, and
+  specialized, internal peripherals (such as UARTs, USB, etc.).
+
+  These chip-specific files are contained within chip-specific
+  sub-directories in the arch/<arch-name>/ directory and are selected
+  via the CONFIG_ARCH_name selection
+
+o Board specific files.  In order to be usable, the chip must be
+  contained in a board environment.  The board configuration defines
+  additional properties of the board including such things as
+  peripheral LEDs, external peripherals (such as network, USB, etc.).
+
+  These board-specific configuration files can be found in the
+  configs/<board-name>/ sub-directories and are discussed in this
+  README.  Additional configuration information maybe available in
+  board-specific configs/<board-name>/README.txt files.
+
+The configs/ subdirectory contains configuration data for each board.  These
+board-specific configurations plus the architecture-specific configurations in
+the arch/ subdirectory completely define a customized port of NuttX.
+
+Directory Structure
+^^^^^^^^^^^^^^^^^^^
+
+The configs directory contains board specific configurationlogic.  Each
+board must provide a subdirectory <board-name> under configs/ with the
+following characteristics:
+
+
+  <board-name>
+  |-- README.txt
+  |-- include/
+  |   `-- (board-specific header files)
+  |-- src/
+  |   |-- Makefile
+  |   `-- (board-specific source files)
+  |-- <config1-dir>
+  |   |-- Make.defs
+  |   |-- defconfig
+  |   |-- appconfig*
+  |   `-- setenv.sh
+  |-- <config2-dir>
+  |   |-- Make.defs
+  |   |-- defconfig
+  |   |-- appconfig*
+  |   `-- setenv.sh
+  ...
+
+  *optional
+
+Summary of Files
+^^^^^^^^^^^^^^^^
+
+README.txt -- This text file provides additional information unique to
+  each board configuration sub-directory.
+
+include/ -- This directory contains board specific header files.  This
+  directory will be linked as include/arch/board at configuration time and
+  can be included via '#include <arch/board/header.h>'.  These header file
+  can only be included by files in arch/<arch-name>include/ and
+  arch/<arch-name>/src
+
+src/ -- This directory contains board specific drivers.  This
+  directory will be linked as arch/<arch-name>/src/board at configuration
+  time and will be integrated into the build system.
+
+src/Makefile -- This makefile will be invoked to build the board specific
+  drivers.  It must support the following targets:  libext$(LIBEXT), clean,
+  and distclean.
+
+A board may have various different configurations using these common source
+files.  Each board configuration is described by three files:  Make.defs,
+defconfig, and setenv.sh.  Typically, each set of configuration files is
+retained in a separate configuration sub-directory (<config1-dir>,
+<config2-dir>, .. in the above diagram).
+
+Make.defs -- This makefile fragment provides architecture and
+  tool-specific build options.  It will be included by all other
+  makefiles in the build (once it is installed).  This make fragment
+  should define:
+
+    Tools: CC, LD, AR, NM, OBJCOPY, OBJDUMP
+    Tool options: CFLAGS, LDFLAGS
+    COMPILE, ASSEMBLE, ARCHIVE, CLEAN, and MKDEP macros
+
+  When this makefile fragment runs, it will be passed TOPDIR which
+  is the path to the root directory of the build.  This makefile
+  fragment may include ${TOPDIR}/.config to perform configuration
+  specific settings.  For example, the CFLAGS will most likely be
+  different if CONFIG_DEBUG=y.
+
+defconfig -- This is a configuration file similar to the Linux
+  configuration file.  In contains variable/value pairs like:
+
+  CONFIG_VARIABLE=value
+
+  This configuration file will be used at build time:
+
+    (1) as a makefile fragment included in other makefiles, and
+    (2) to generate include/nuttx/config.h which is included by
+        most C files in the system.
+
+  The following variables are recognized by the build (you may
+  also include architecture/board-specific settings).
+
+  Architecture selection:
+
+    CONFIG_ARCH - Identifies the arch/ subdirectory
+    CONFIG_ARCH_name - For use in C code
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+    CONFIG_ARCH_CHIP_name - For use in C code
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+    CONFIG_ARCH_BOARD_name - For use in C code
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+    CONFIG_ARCH_NOINTC - define if the architecture does not
+      support an interrupt controller or otherwise cannot support
+      APIs like up_enable_irq() and up_disable_irq().
+    CONFIG_ARCH_VECNOTIRQ - Usually the interrupt vector number provided
+      to interfaces like irq_attach() and irq_detach are the same as IRQ
+      numbers that are provied to IRQ management functions like
+      up_enable_irq() and up_disable_irq().  But that is not true for all
+      interrupt controller implementations.  For example, the PIC32MX
+      interrupt controller manages interrupt sources that have a many-to-one
+      relationship to interrupt vectors. In such cases, CONFIG_ARCH_VECNOTIRQ
+      must defined so that the OS logic will know not to assume it can use
+      a vector number to enable or disable interrupts.
+    CONFIG_ARCH_IRQPRIO
+      Define if the architecture suports prioritizaton of interrupts
+      and the up_prioritize_irq() API.
+
+  Some architectures require a description of the RAM configuration:
+
+    CONFIG_DRAM_SIZE - Describes the installed DRAM.
+    CONFIG_DRAM_START - The start address of DRAM (physical)
+    CONFIG_DRAM_VSTART - The start address of DRAM (virtual)
+
+  General build options:
+
+    CONFIG_RRLOAD_BINARY - make the rrload binary format used with
+      BSPs from www.ridgerun.com using the tools/mkimage.sh script.
+    CONFIG_INTELHEX_BINARY - make the Intel HEX binary format
+      used with many different loaders using the GNU objcopy program
+      Should not be selected if you are not using the GNU toolchain.
+    CONFIG_MOTOROLA_SREC - make the Motorola S-Record binary format
+      used with many different loaders using the GNU objcopy program
+      Should not be selected if you are not using the GNU toolchain.
+    CONFIG_RAW_BINARY - make a raw binary format file used with many
+      different loaders using the GNU objcopy program.  This option
+      should not be selected if you are not using the GNU toolchain.
+    CONFIG_HAVE_LIBM - toolchain supports libm.a
+    CONFIG_HAVE_CXX - toolchain supports C++ and CXX, CXXFLAGS, and
+      COMPILEXX have been defined in the configurations Make.defs
+      file.
+    CONFIG_HAVE_CXXINITIALIZE - The platform-specific logic includes support
+      for initialization of static C++ instances for this architecture
+      and for the selected toolchain (via up_cxxinitialize()).
+
+  Building application code:
+
+    CONFIG_APPS_DIR - Identifies the directory that builds the
+      application to link with NuttX.  Default: ../apps This symbol must be assigned
+      to the path to the application build directory *relative* to
+      the NuttX top build direcory. If you had an application
+      directory and the NuttX directory each in separate directory
+      trees like this:
+
+      build
+       |-nuttx
+       |  |
+       |  `- Makefile
+       `-application
+       |
+       `- Makefile
+
+      Then you would set CONFIG_APPS_DIR=../application.
+
+      The application direction must contain Makefile and this make
+      file must support the following targets:
+
+      - libapps$(LIBEXT) (usually libapps.a). libapps.a is a static
+      library ( an archive) that contains all of application object
+      files.
+      - clean. Do whatever is appropriate to clean the application
+      directories for a fresh build.
+      - distclean. Clean everthing -- auto-generated files, symbolic
+      links etc. -- so that the directory contents are the same as
+      the contents in your configuration management system.
+      This is only done when you change the NuttX configuration.
+      - depend. Make or update the application build dependencies.
+
+      When this application is invoked it will receive the setting TOPDIR like:
+
+      $(MAKE) -C $(CONFIG_APPS_DIR) TOPDIR="$(TOPDIR)" <target>
+
+      TOPDIR is the full path to the NuttX directory. It can be used, for
+      example, to include makefile fragments (e.g., .config or Make.defs)
+      or to set up include file paths.
+
+  Two-pass build options.  If the 2 pass build option is selected, then these
+  options configure the make system build a extra link object. This link object
+  is assumed to be an incremental (relative) link object, but could be a static
+  library (archive) (some modification to this Makefile would be required if
+  CONFIG_PASS1_TARGET generates an archive). Pass 1 1ncremental (relative) link
+  objects should be put into the processor-specific source directory (where other
+  link objects will be created).  If the pass1 obect is an archive, it could
+  go anywhere.
+
+    CONFIG_BUILD_2PASS - Enables the two pass build options.
+
+  When the two pass build option is enabled, the following also apply:
+
+    CONFIG_PASS1_TARGET - The name of the first pass build target.  This
+      can be specific build target, a special build target (all, default, etc.)
+      or may just be left undefined.
+    CONFIG_PASS1_BUILDIR - The path, relative to the top NuttX build
+      directory to directory that contains the Makefile to build the
+      first pass object.  The Makefile must support the following targets:
+      - The special target CONFIG_PASS1_TARGET (if defined)
+      - and the usual depend, clean, and distclean targets.
+    CONFIG_PASS1_OBJECT - May be used to include an extra, pass1 object
+      into the final link.  This would probably be the object generated
+      from the CONFIG_PASS1_TARGET.  It may be available at link time
+      in the arch/<architecture>/src directory.
+
+  General OS setup
+
+    CONFIG_DEBUG - enables built-in debug options
+    CONFIG_DEBUG_VERBOSE - enables verbose debug output
+    CCONFIG_DEBUG_ENABLE - Support an interface to enable or disable debug output.
+    CONFIG_DEBUG_SYMBOLS - build without optimization and with
+      debug symbols (needed for use with a debugger).
+    CONFIG_DEBUG_SCHED - enable OS debug output (disabled by
+      default)
+    CONFIG_DEBUG_MM - enable memory management debug output
+      (disabled by default)
+    CONFIG_DEBUG_NET - enable network debug output (disabled
+      by default)
+    CONFIG_DEBUG_USB - enable usb debug output (disabled by
+      default)
+    CONFIG_DEBUG_FS - enable filesystem debug output (disabled
+      by default)
+    CONFIG_DEBUG_LIB - enable C library debug output (disabled
+      by default)
+    CONFIG_DEBUG_BINFMT - enable binary loader debug output (disabled
+      by default)
+    CONFIG_DEBUG_GRAPHICS - enable NX graphics debug output
+      (disabled by default)
+
+    CONFIG_MM_REGIONS - If the architecture includes multiple
+      regions of memory to allocate from, this specifies the
+      number of memory regions that the memory manager must
+      handle and enables the API mm_addregion(start, end);
+    CONFIG_MM_SMALL - Each memory allocation has a small allocation
+      overhead.  The size of that overhead is normally determined by
+      the "width" of the address support by the MCU.  MCUs that support
+      16-bit addressability have smaller overhead than devices that
+      support 32-bit addressability.  However, there are many MCUs
+      that support 32-bit addressability *but* have internal SRAM
+      of size less than or equal to 64Kb.  In this case, CONFIG_MM_SMALL
+      can be defined so that those MCUs will also benefit from the
+      smaller, 16-bit-based allocation overhead.
+    CONFIG_HEAP2_BASE and CONFIG_HEAP2_SIZE
+      Some architectures use these settings to specify the size of
+      a second heap region.
+    CONFIG_GRAN
+      Enable granual allocator support.  Allocations will be aligned to the
+      granule size; allocations will be in units of the granule size.
+      Larger granules will give better performance and less overhead but
+      more losses of memory due to alignment and quantization waste.
+      NOTE: The current implementation also restricts the maximum
+      allocation size to 32 granaules.  That restriction could be
+      eliminated with some additional coding effort.
+    CONFIG_GRAN_SINGLE
+      Select if there is only one instance of the granule allocator (i.e.,
+      gran_initialize will be called only once. In this case, (1) there
+      are a few optimizations that can can be done and (2) the GRAN_HANDLE
+      is not needed.
+    CONFIG_GRAN_INTR - Normally mutual exclusive access to granule allocator
+      data is assured using a semaphore.  If this option is set then, instead,
+      mutual exclusion logic will disable interrupts.  While this options is
+      more invasive to system performance, it will also support use of the
+      granule allocator from interrupt level logic.
+    CONFIG_DEBUG_GRAM
+      Just like CONFIG_DEBUG_MM, but only generates ouput from the gran
+      allocation logic.
+
+    CONFIG_ARCH_LOWPUTC - architecture supports low-level, boot
+      time console output
+    CONFIG_MSEC_PER_TICK - The default system timer is 100Hz
+      or MSEC_PER_TICK=10.  This setting may be defined to
+      inform NuttX that the processor hardware is providing
+      system timer interrupts at some interrupt interval other
+      than 10 msec.
+    CONFIG_RR_INTERVAL - The round robin timeslice will be set
+      this number of milliseconds;  Round robin scheduling can
+      be disabled by setting this value to zero.
+    CONFIG_SCHED_INSTRUMENTATION - enables instrumentation in 
+      scheduler to monitor system performance
+    CONFIG_TASK_NAME_SIZE - Specifies that maximum size of a
+      task name to save in the TCB.  Useful if scheduler
+      instrumentation is selected.  Set to zero to disable.
+    CONFIG_START_YEAR, CONFIG_START_MONTH, CONFIG_START_DAY -
+      Used to initialize the internal time logic.
+    CONFIG_GREGORIAN_TIME - Enables Gregorian time conversions.
+      You would only need this if you are concerned about accurate
+      time conversions in the past or in the distant future.
+    CONFIG_JULIAN_TIME - Enables Julian time conversions. You
+      would only need this if you are concerned about accurate
+      time conversion in the distand past.  You must also define
+      CONFIG_GREGORIAN_TIME in order to use Julian time.
+    CONFIG_DEV_CONSOLE - Set if architecture-specific logic
+      provides /dev/console.  Enables stdout, stderr, stdin.
+      This implies the "normal" serial driver provides the
+      console unless another console device is specified
+      (See CONFIG_DEV_LOWCONSOLE).
+    CONFIG_MUTEX_TYPES - Set to enable support for recursive and
+      errorcheck mutexes.  Enables pthread_mutexattr_settype().
+    CONFIG_PRIORITY_INHERITANCE - Set to enable support for
+      priority inheritance on mutexes and semaphores.
+      Priority inheritance is a strategy for addressing priority
+      inversion.
+    CONFIG_SEM_PREALLOCHOLDERS: This setting is only used if priority
+      inheritance is enabled.  It defines the maximum number of
+      different threads (minus one) that can take counts on a
+      semaphore with priority inheritance support.  This may be 
+      set to zero if priority inheritance is disabled OR if you
+      are only using semaphores as mutexes (only one holder) OR
+      if no more than two threads participate using a counting
+      semaphore.  If defined, then this should be a relatively
+      large number because this is the total number of counts on
+      the total number of semaphores (like 64 or 100).
+    CONFIG_SEM_NNESTPRIO.  If priority inheritance is enabled,
+      then this setting is the maximum number of higher priority
+      threads (minus 1) than can be waiting for another thread
+      to release a count on a semaphore.  This value may be set
+      to zero if no more than one thread is expected to wait for
+      a semaphore.  If defined, then this should be a relatively
+      small number because this the number of maximumum of waiters
+      on one semaphore (like 4 or 8).
+    CONFIG_FDCLONE_DISABLE. Disable cloning of all file descriptors
+      by task_create() when a new task is started.  If set, all
+        files/drivers will appear to be closed in the new task.
+    CONFIG_FDCLONE_STDIO. Disable cloning of all but the first
+      three file descriptors (stdin, stdout, stderr) by task_create()
+      when a new task is started. If set, all files/drivers will
+      appear to be closed in the new task except for stdin, stdout,
+      and stderr.
+    CONFIG_SDCLONE_DISABLE. Disable cloning of all socket
+      desciptors by task_create() when a new task is started. If
+      set, all sockets will appear to be closed in the new task.
+    CONFIG_NXFLAT. Enable support for the NXFLAT binary format.
+      This format will support execution of NuttX binaries located
+      in a ROMFS filesystem (see examples/nxflat).
+    CONFIG_SCHED_WORKQUEUE.  Create a dedicated "worker" thread to
+      handle delayed processing from interrupt handlers.  This feature
+      is required for some drivers but, if there are not complaints,
+      can be safely disabled.  The worker thread also performs
+      garbage collection -- completing any delayed memory deallocations
+      from interrupt handlers.  If the worker thread is disabled,
+      then that clean will be performed by the IDLE thread instead
+      (which runs at the lowest of priority and may not be appropriate
+      if memory reclamation is of high priority).  If CONFIG_SCHED_WORKQUEUE
+      is enabled, then the following options can also be used:
+    CONFIG_SCHED_WORKPRIORITY - The execution priority of the worker
+      thread.  Default: 192
+    CONFIG_SCHED_WORKPERIOD - How often the worker thread checks for
+      work in units of microseconds.  Default: 50*1000 (50 MS).
+    CONFIG_SCHED_WORKSTACKSIZE - The stack size allocated for the worker
+      thread.  Default: CONFIG_IDLETHREAD_STACKSIZE.
+    CONFIG_SIG_SIGWORK - The signal number that will be used to wake-up
+      the worker thread.  Default: 4
+    CONFIG_SCHED_LPWORK. If CONFIG_SCHED_WORKQUEUE is defined, then a single
+      work queue is created by default.  If CONFIG_SCHED_LPWORK is also defined
+      then an additional, lower-priority work queue will also be created.  This
+      lower priority work queue is better suited for more extended processing
+      (such as file system clean-up operations)
+    CONFIG_SCHED_LPWORKPRIORITY - The execution priority of the lower priority
+      worker thread.  Default: 50
+    CONFIG_SCHED_LPWORKPERIOD - How often the lower priority worker thread
+      checks for work in units of microseconds.  Default: 50*1000 (50 MS).
+    CONFIG_SCHED_LPWORKSTACKSIZE - The stack size allocated for the lower
+      priority worker thread.  Default: CONFIG_IDLETHREAD_STACKSIZE.
+    CONFIG_SCHED_WAITPID - Enables the waitpid() API
+    CONFIG_SCHED_ATEXIT -  Enables the atexit() API
+    CONFIG_SCHED_ATEXIT_MAX -  By default if CONFIG_SCHED_ATEXIT is
+      selected, only a single atexit() function is supported. That number
+      can be increased by defined this setting to the number that you require.
+    CONFIG_SCHED_ONEXIT -  Enables the on_exit() API
+    CONFIG_SCHED_ONEXIT_MAX -  By default if CONFIG_SCHED_ONEXIT is selected,
+      only a single on_exit() function is supported. That number can be
+      increased by defined this setting to the number that you require.
+    CONFIG_USER_ENTRYPOINT - The name of the entry point for user
+      applications.  For the example applications this is of the form 'app_main'
+      where 'app' is the application name. If not defined, CONFIG_USER_ENTRYPOINT
+      defaults to user_start.
+
+  System Logging:
+    CONFIG_SYSLOG enables general system logging support.
+    CONFIG_SYSLOG_DEVPATH - The full path to the system logging device.  Default
+      "/dev/ramlog" (RAMLOG) or "dev/ttyS1" (character device)
+
+    At present, there are two system loggins devices available. If CONFIG_SYSLOG
+    is selected, then these options are also available.
+
+    CONFIG_SYSLOG_CHAR - Enable the generic character device for the SYSLOG.
+      A disadvantage of using the generic character device for the SYSLOG is that
+      it cannot handle debug output generated from interrupt level handlers.
+      NOTE:  No more than one SYSLOG device should be configured.
+
+    CONFIG_RAMLOG - Enables the RAM logging feature. The RAM log is a circular
+      buffer in RAM. NOTE:  No more than one SYSLOG device should be configured.
+    CONFIG_RAMLOG_CONSOLE - Use the RAM logging device as a system console.
+      If this feature is enabled (along with CONFIG_DEV_CONSOLE), then all
+      console output will be re-directed to a circular buffer in RAM.  This
+      is useful, for example, if the only console is a Telnet console.  Then
+      in that case, console output from non-Telnet threads will go to the
+      circular buffer and can be viewed using the NSH 'dmesg' command.
+    CONFIG_RAMLOG_SYSLOG - Use the RAM logging device for the syslogging
+      interface.  If this feature is enabled (along with CONFIG_SYSLOG),
+      then all debug output (only) will be re-directed to the circular
+      buffer in RAM.  This RAM log can be view from NSH using the 'dmesg'
+      command.  NOTE:  Unlike the limited, generic character driver SYSLOG
+      device, the RAMLOG *can* be used to generate debug output from interrupt
+      level handlers.
+    CONFIG_RAMLOG_NPOLLWAITERS - The number of threads than can be waiting
+     for this driver on poll().  Default: 4
+
+    If CONFIG_RAMLOG_CONSOLE or CONFIG_RAMLOG_SYSLOG is selected, then the
+    following may also be provided:
+
+    CONFIG_RAMLOG_CONSOLE_BUFSIZE - Size of the console RAM log.  Default: 1024
+
+  Kernel build options:
+    CONFIG_NUTTX_KERNEL - Builds NuttX as a separately compiled kernel.
+    CONFIG_SYS_RESERVED - Reserved system call values for use
+      by architecture-specific logic.
+
+  OS setup related to on-demand paging:
+
+    CONFIG_PAGING - If set =y in your configation file, this setting will
+      enable the on-demand paging feature as described in
+      http://www.nuttx.org/NuttXDemandPaging.html.
+
+  If CONFIG_PAGING is selected, then you will probabaly need CONFIG_BUILD_2PASS to
+  correctly position the code and the following configuration options also apply:
+
+    CONFIG_PAGING_PAGESIZE - The size of one managed page.  This must
+      be a value supported by the processor's memory management unit.
+    CONFIG_PAGING_NLOCKED - This is the number of locked pages in the
+      memory map.  The locked address region will then be from
+      CONFIG_DRAM_VSTART through (CONFIG_DRAM_VSTART +
+      CONFIG_PAGING_PAGESIZE*CONFIG_PAGING_NLOCKED)
+    CONFIG_PAGING_LOCKED_PBASE and CONFIG_PAGING_LOCKED_VBASE - These
+      may be defined to determine the base address of the locked page
+      regions.  If neither are defined, the logic will be set the bases
+      to CONFIG_DRAM_START and CONFIG_DRAM_VSTART (i.e., it assumes
+      that the base address of the locked region is at the beginning
+      of RAM).
+      NOTE:  In some architectures, it may be necessary to take some
+      memory from the beginning of this region for vectors or for a
+      page table. In such cases, CONFIG_PAGING_LOCKED_P/VBASE should
+      take that into consideration to prevent overlapping the locked
+      memory region and the system data at the beginning of SRAM.
+    CONFIG_PAGING_NPPAGED - This is the number of physical pages
+      available to support the paged text region.  This paged region
+      begins at (CONFIG_PAGING_LOCKED_PBASE + CONFIG_PAGING_PAGESIZE*CONFIG_PAGING_NPPAGED)
+      and continues until (CONFIG_PAGING_LOCKED_PBASE + CONFIG_PAGING_PAGESIZE*(CONFIG_PAGING_NLOCKED +
+      CONFIG_PAGING_NPPAGED)
+    CONFIG_PAGING_NVPAGED - This actual size of the paged text region
+      (in pages).  This is also the number of virtual pages required to
+      support the entire paged region. The on-demand paging feature is
+      intended to support only the case where the virtual paged text
+      area is much larger the available physical pages.  Otherwise, why
+      would you enable on-demand paging?
+    CONFIG_PAGING_NDATA - This is the number of data pages in the memory
+      map.  The data region will extend to the end of RAM unless overridden
+      by a setting in the configuration file.
+      NOTE:  In some architectures, it may be necessary to take some memory
+      from the end of RAM for page tables or other system usage.  The
+      configuration settings and linker directives must be cognizant of that:
+      CONFIG_PAGING_NDATA should be defined to prevent the data region from
+      extending all the way to the end of memory. 
+    CONFIG_PAGING_DEFPRIO - The default, minimum priority of the page fill
+      worker thread.  The priority of the page fill work thread will be boosted
+      boosted dynmically so that it matches the priority of the task on behalf
+      of which it peforms the fill.  This defines the minimum priority that
+      will be used. Default: 50.
+    CONFIG_PAGING_STACKSIZE - Defines the size of the allocated stack
+      for the page fill worker thread. Default: 1024.
+    CONFIG_PAGING_BLOCKINGFILL - The architecture specific up_fillpage()
+      function may be blocking or non-blocking.  If defined, this setting
+      indicates that the up_fillpage() implementation will block until the
+      transfer is completed. Default:  Undefined (non-blocking).
+    CONFIG_PAGING_WORKPERIOD - The page fill worker thread will wake periodically
+      even if there is no mapping to do.  This selection controls that wake-up
+      period (in microseconds).  This wake-up a failsafe that will handle any 
+      cases where a single is lost (that would really be a bug and shouldn't
+      happen!) and also supports timeouts for case of non-blocking, asynchronous
+      fills (see CONFIG_PAGING_TIMEOUT_TICKS).
+    CONFIG_PAGING_TIMEOUT_TICKS - If defined, the implementation will monitor
+      the (asynchronous) page fill logic.  If the fill takes longer than this
+      number if microseconds, then a fatal error will be declared.
+      Default: No timeouts monitored.
+
+    Some architecture-specific settings.  Defaults are architecture specific.
+    If you don't know what you are doing, it is best to leave these undefined
+    and try the system defaults:
+ 
+    CONFIG_PAGING_VECPPAGE - This the physical address of the page in
+      memory to be mapped to the vector address.
+    CONFIG_PAGING_VECL2PADDR - This is the physical address of the L2
+      page table entry to use for the vector mapping.
+    CONFIG_PAGING_VECL2VADDR - This is the virtual address of the L2
+      page table entry to use for the vector mapping.
+    CONFIG_PAGING_BINPATH - If CONFIG_PAGING_BINPATH is defined, then it
+      is the full path to a file on a mounted file system that contains
+      a binary image of the NuttX executable.  Pages will be filled by
+      reading from offsets into this file that correspond to virtual
+      fault addresses.
+    CONFIG_PAGING_MOUNTPT - If CONFIG_PAGING_BINPATH is defined, additional
+      options may be provided to control the initialization of underlying
+      devices. CONFIG_PAGING_MOUNTPT identifies the mountpoint to be used
+      if a device is mounted.
+    CONFIG_PAGING_MINOR - Some mount operations require a "minor" number
+      to identify the specific device instance. Default: 0
+    CONFIG_PAGING_SDSLOT - If CONFIG_PAGING_BINPATH is defined, additional
+      options may be provided to control the initialization of underlying
+      devices. CONFIG_PAGING_SDSLOT identifies the slot number of the SD
+      device to initialize. This must be undefined if SD is not being used.
+      This should be defined to be zero for the typical device that has
+      only a single slot (See CONFIG_MMCSD_NSLOTS). If defined, 
+      CONFIG_PAGING_SDSLOT will instruct certain board-specific logic to
+      initialize the media in this SD slot.
+    CONFIG_PAGING_M25PX - Use the m25px.c FLASH driver.  If this is selected,
+      then the MTD interface to the M25Px device will be used to support
+      paging.
+    CONFIG_PAGING_AT45DB - Use the at45db.c FLASH driver.  If this is selected,
+      then the MTD interface to the Atmel AT45DB device will be used to support
+      paging.
+    CONFIG_PAGING_BINOFFSET - If CONFIG_PAGING_M25PX or is CONFIG_PAGING_AT45DB
+      defined then CONFIG_PAGING_BINOFFSET will be used to specify the offset
+      in bytes into the FLASH device where the NuttX binary image is located.
+      Default: 0
+    CONFIG_PAGING_SPIPORT - If CONFIG_PAGING_M25PX CONFIG_PAGING_AT45DB is
+       defined and the device has multiple SPI busses (ports), then this
+      configuration should be set to indicate which SPI port the device is
+      connected. Default: 0
+
+  The following can be used to disable categories of APIs supported
+  by the OS.  If the compiler supports weak functions, then it
+  should not be necessary to disable functions unless you want to
+  restrict usage of those APIs.
+
+  There are certain dependency relationships in these features.
+
+    o mq_notify logic depends on signals to awaken tasks
+      waiting for queues to become full or empty.
+    o pthread_condtimedwait() depends on signals to wake
+      up waiting tasks.
+
+    CONFIG_DISABLE_CLOCK, CONFIG_DISABLE_POSIX_TIMERS, CONFIG_DISABLE_PTHREAD.
+    CONFIG_DISABLE_SIGNALS, CONFIG_DISABLE_MQUEUE, CONFIG_DISABLE_MOUNTPOUNT,
+    CONFIG_DISABLE_ENVIRON, CONFIG_DISABLE_POLL
+
+  Misc libc settings
+
+    CONFIG_NOPRINTF_FIELDWIDTH - sprintf-related logic is a little smaller
+      if we do not support fieldwidthes
+    CONFIG_LIBC_FLOATINGPOINT - By default, floating point support in printf,
+      sscanf, etc. is disabled.
+    CONFIG_LIBC_STRERROR - strerror() is useful because it decodes 'errno'
+      values into a human readable strings.  But it can also require
+      a lot of memory.  If this option is selected, strerror() will still
+      exist in the build but it will not decode error values.  This option
+      should be used by other logic to decide if it should use strerror() or
+      not.  For example, the NSH application will not use strerror() if this
+      option is not selected; perror() will not use strerror() is this option
+      is not selected (see also CONFIG_NSH_STRERROR).
+    CONFIG_LIBC_STRERROR_SHORT - If this option is selected, then strerror()
+      will use a shortened string when it decodes the error.  Specifically,
+      strerror() is simply use the string that is the common name for the
+      error.  For example, the 'errno' value of 2 will produce the string
+      "No such file or directory" if CONFIG_LIBC_STRERROR_SHORT is not
+      defined but the string "ENOENT" if CONFIG_LIBC_STRERROR_SHORT is
+      defined.
+    CONFIG_LIBC_PERROR_STDOUT - POSIX requires that perror() provide its output
+      on stderr.  This option may be defined, however, to provide perror() output
+      that is serialized with other stdout messages.
+
+  Allow for architecture optimized implementations
+
+    The architecture can provide optimized versions of the
+    following to improve system performance
+
+      CONFIG_ARCH_MEMCPY, CONFIG_ARCH_MEMCMP, CONFIG_ARCH_MEMMOVE
+      CONFIG_ARCH_MEMSET, CONFIG_ARCH_STRCMP, CONFIG_ARCH_STRCPY
+      CONFIG_ARCH_STRNCPY, CONFIG_ARCH_STRLEN, CONFIG_ARCH_STRNLEN
+      CONFIG_ARCH_BZERO
+
+  The architecture may provide custom versions of certain standard header
+  files:
+
+    CONFIG_ARCH_STDBOOL_H - The stdbool.h header file can be found at
+      nuttx/include/stdbool.h. However, that header includes logic to redirect
+      the inclusion of an architecture specific header file like:
+
+        #ifdef CONFIG_ARCH_STDBOOL_H
+        #  include <arch/stdbool.h>
+        #else
+        ...
+        #endif
+
+      Recall that that include path, include/arch, is a symbolic link and
+      will refer to a version of stdbool.h at nuttx/arch/<architecture>/include/stdbool.h.
+
+    CONFIG_ARCH_STDINT_H - Similar logic exists for the stdint.h header
+      file can also be found at nuttx/include/stdint.h.
+
+        #ifdef CONFIG_ARCH_STDBOOL_H
+        #  include <arch/stdinit.h>
+        #else
+        ...
+        #endif
+
+    CONFIG_ARCH_MATH_H - There is also a re-directing version of math.h in
+      the source tree. However, it resides out-of-the-way at include/nuttx/math.h
+      because it conflicts too often with the system math.h. If CONFIG_ARCH_MATH_H=y
+      is  defined, however, the top-level makefile will copy the redirecting
+      math.h header file from include/nuttx/math.h to include/math.h. math.h
+      will then include the architecture-specific version of math.h that you
+      must provide at nuttx/arch/>architecture</include/math.h.
+
+        #ifdef CONFIG_ARCH_MATH_H
+        #  include <arch/math.h>
+        #endif
+
+      So for the architectures that define CONFIG_ARCH_MATH_H=y, include/math.h
+      will be the redirecting math.h header file; for the architectures that
+      don't select CONFIG_ARCH_MATH_H, the redirecting math.h header file will
+      stay out-of-the-way in include/nuttx/.
+
+    CONFIG_ARCH_STDARG_H - There is also a redirecting version of stdarg.h in
+      the source tree as well. It also resides out-of-the-way at include/nuttx/stdarg.h.
+      This is because you should normally use your toolchain's stdarg.h file. But
+      sometimes, your toolchain's stdarg.h file may have other header file
+      dependencies and so may not be usable in the NuttX build environment. In
+      those cases, you may have to create a architecture-specific stdarg.h header
+      file at nuttx/arch/>architecture</include/stdarg.h
+
+      If CONFIG_ARCH_STDARG_H=y is defined, the top-level makefile will copy the
+      re-directing stdarg.h header file from include/nuttx/stdarg.h to
+      include/stdarg.h. So for the architectures that cannot use their toolchain's
+      stdarg.h file, they can use this alternative by defining CONFIG_ARCH_STDARG_H=y
+      and providing. If CONFIG_ARCH_STDARG_H, is not defined, then the stdarg.h
+      header file will stay out-of-the-way in include/nuttx/.
+
+    CONFIG_ARCH_ROMGETC - In Harvard architectures, data accesses and
+      instruction accesses occur on different busses, perhaps
+      concurrently.  All data accesses are performed on the data bus
+      unless special machine instructions are used to read data
+      from the instruction address space.  Also, in the typical
+      MCU, the available SRAM data memory is much smaller that the
+      non-volatile FLASH instruction memory.  So if the application
+      requires many constant strings, the only practical solution may
+      be to store those constant strings in FLASH memory where they
+      can only be accessed using architecture-specific machine
+      instructions.
+
+      If CONFIG_ARCH_ROMGETC is defined, then the architecture logic
+      must export the function up_romgetc().  up_romgetc() will simply
+      read one byte of data from the instruction space.
+ 
+      If CONFIG_ARCH_ROMGETC, certain C stdio functions are effected:
+      (1) All format strings in printf, fprintf, sprintf, etc. are
+      assumed to lie in FLASH (string arguments for %s are still assumed
+      to reside in SRAM). And (2), the string argument to puts and fputs
+      is assumed to reside in FLASH.  Clearly, these assumptions may have
+      to modified for the particular needs of your environment.  There
+      is no "one-size-fits-all" solution for this problem.
+
+  Sizes of configurable things (0 disables)
+
+    CONFIG_MAX_TASKS - The maximum number of simultaneously
+      active tasks.  This value must be a power of two.
+    CONFIG_NPTHREAD_KEYS - The number of items of thread-
+      specific data that can be retained
+    CONFIG_NFILE_DESCRIPTORS - The maximum number of file
+      descriptors (one for each open)
+    CONFIG_NFILE_STREAMS - The maximum number of streams that
+      can be fopen'ed
+    CONFIG_NAME_MAX - Maximum number of bytes in a filename (not including
+      terminating null).  Default: 32
+    CONFIG_PATH_MAX - Maximum number of bytes in a pathname, including the
+      terminating null character.  Default: MIN(256,(4*CONFIG_NAME_MAX+1))
+    CONFIG_STDIO_BUFFER_SIZE - Size of the buffer to allocate
+      on fopen. (Only if CONFIG_NFILE_STREAMS > 0)
+    CONFIG_STDIO_LINEBUFFER - If standard C buffered I/O is enabled
+      (CONFIG_STDIO_BUFFER_SIZE > 0), then this option may be added
+      to force automatic, line-oriented flushing the output buffer
+      for putc(), fputc(), putchar(), puts(), fputs(), printf(),
+      fprintf(), and vfprintf().  When a newline is encountered in
+      the output string, the output buffer will be flushed.  This
+      (slightly) increases the NuttX footprint but supports the kind
+      of behavior that people expect for printf().
+    CONFIG_NUNGET_CHARS - Number of characters that can be
+      buffered by ungetc() (Only if CONFIG_NFILE_STREAMS > 0)
+    CONFIG_PREALLOC_MQ_MSGS - The number of pre-allocated message
+      structures.  The system manages a pool of preallocated
+      message structures to minimize dynamic allocations
+    CONFIG_PREALLOC_IGMPGROUPS - Pre-allocated IGMP groups are used
+      only if needed from interrupt level group created (by the IGMP server).
+      Default: 4.
+    CONFIG_MQ_MAXMSGSIZE - Message structures are allocated with
+      a fixed payload size given by this settin (does not include
+      other message structure overhead.
+    CONFIG_PREALLOC_WDOGS - The number of pre-allocated watchdog
+      structures.  The system manages a pool of preallocated
+      watchdog structures to minimize dynamic allocations
+    CONFIG_DEV_PIPE_SIZE - Size, in bytes, of the buffer to allocated
+      for pipe and FIFO support
+
+  Filesystem configuration
+
+    CONFIG_FS_FAT - Enable FAT filesystem support
+    CONFIG_FAT_LCNAMES - Enable use of the NT-style upper/lower case 8.3
+      file name support.
+    CONFIG_FAT_LFN - Enable FAT long file names.  NOTE:  Microsoft claims
+      patents on FAT long file name technology.  Please read the
+      disclaimer in the top-level COPYING file and only enable this
+      feature if you understand these issues.
+    CONFIG_FAT_MAXFNAME - If CONFIG_FAT_LFN is defined, then the
+      default, maximum long file name is 255 bytes.  This can eat up
+      a lot of memory (especially stack space).  If you are willing
+      to live with some non-standard, short long file names, then
+      define this value.  A good choice would be the same value as
+      selected for CONFIG_NAME_MAX which will limit the visibility
+      of longer file names anyway.
+    CONFIG_FS_FATTIME: Support FAT date and time. NOTE:  There is not
+      much sense in supporting FAT date and time unless you have a
+      hardware RTC or other way to get the time and date.
+    CONFIG_FS_NXFFS: Enable NuttX FLASH file system (NXFF) support.
+    CONFIG_NXFFS_ERASEDSTATE: The erased state of FLASH. 
+      This must have one of the values of 0xff or 0x00.
+      Default: 0xff.
+    CONFIG_NXFFS_PACKTHRESHOLD: When packing flash file data,
+      don't both with file chunks smaller than this number of data bytes.
+      Default: 32.
+    CONFIG_NXFFS_MAXNAMLEN: The maximum size of an NXFFS file name.
+      Default: 255.
+    CONFIG_NXFFS_PACKTHRESHOLD: When packing flash file data,
+      don't both with file chunks smaller than this number of data bytes.
+      Default: 32.
+    CONFIG_NXFFS_TAILTHRESHOLD: clean-up can either mean
+      packing files together toward the end of the file or, if file are
+      deleted at the end of the file, clean up can simply mean erasing
+      the end of FLASH memory so that it can be re-used again.  However,
+      doing this can also harm the life of the FLASH part because it can
+      mean that the tail end of the FLASH is re-used too often. This
+      threshold determines if/when it is worth erased the tail end of FLASH
+      and making it available for re-use (and possible over-wear).
+      Default: 8192.
+    CONFIG_FS_ROMFS - Enable ROMFS filesystem support
+    CONFIG_NFS - Enable Network File System (NFS) client file system support.
+      Provided support is version 3 using UDP.  In addition to common
+      prerequisites for mount-able file systems in general, this option
+      requires UDP networking support; this would include CONFIG_NETand
+      CONFIG_NET_UDP at a minimum.
+    CONFIG_FS_RAMMAP - For file systems that do not support XIP, this
+      option will enable a limited form of memory mapping that is
+      implemented by copying whole files into memory.
+
+  RTC
+
+    CONFIG_RTC - Enables general support for a hardware RTC.  Specific
+      architectures may require other specific settings.
+    CONFIG_RTC_DATETIME - There are two general types of RTC:  (1) A simple
+      battery backed counter that keeps the time when power is down, and (2)
+       A full date / time RTC the provides the date and time information, often
+      in BCD format.  If CONFIG_RTC_DATETIME is selected, it specifies this
+      second kind of RTC. In this case, the RTC is used to "seed" the normal
+      NuttX timer and the NuttX system timer provides for higher resoution
+      time.
+    CONFIG_RTC_HIRES - If CONFIG_RTC_DATETIME not selected, then the simple,
+      battery backed counter is used.  There are two different implementations
+      of such simple counters based on the time resolution of the counter:
+      The typical RTC keeps time to resolution of 1 second, usually
+      supporting a 32-bit time_t value.  In this case, the RTC is used to
+      "seed" the normal NuttX timer and the NuttX timer provides for higher
+      resoution time. If CONFIG_RTC_HIRES is enabled in the NuttX configuration,
+      then the RTC provides higher resolution time and completely replaces the
+      system timer for purpose of date and time.
+    CONFIG_RTC_FREQUENCY - If CONFIG_RTC_HIRES is defined, then the frequency
+      of the high resolution RTC must be provided.  If CONFIG_RTC_HIRES is
+      not defined, CONFIG_RTC_FREQUENCY is assumed to be one.
+    CONFIG_RTC_ALARM - Enable if the RTC hardware supports setting of an
+      alarm.  A callback function will be executed when the alarm goes off
+
+  CAN driver
+
+    CONFIG_CAN - Enables CAN support (one or both of CONFIG_STM32_CAN1 or
+      CONFIG_STM32_CAN2 must also be defined)
+    CONFIG_CAN_EXTID - Enables support for the 29-bit extended ID.  Default
+      Standard 11-bit IDs.
+    CONFIG_CAN_FIFOSIZE - The size of the circular buffer of CAN messages.
+      Default: 8
+    CONFIG_CAN_NPENDINGRTR - The size of the list of pending RTR requests.
+      Default: 4
+    CONFIG_CAN_LOOPBACK - A CAN driver may or may not support a loopback
+      mode for testing. If the driver does support loopback mode, the setting
+      will enable it. (If the driver does not, this setting will have no effect).
+
+  SPI driver
+
+    CONFIG_SPI_OWNBUS - Set if there is only one active device
+      on the SPI bus.  No locking or SPI configuration will be performed.
+      It is not necessary for clients to lock, re-configure, etc..
+    CONFIG_SPI_EXCHANGE - Driver supports a single exchange method
+      (vs a recvblock() and sndblock ()methods)
+
+  SPI-based MMC/SD driver
+
+    CONFIG_MMCSD_NSLOTS - Number of MMC/SD slots supported by the
+      driver. Default is one.
+    CONFIG_MMCSD_READONLY -  Provide read-only access.  Default is
+      Read/Write
+    CONFIG_MMCSD_SPICLOCK - Maximum SPI clock to drive MMC/SD card.
+      Default is 20MHz.
+
+  SDIO/SDHC driver:
+
+    CONFIG_SDIO_DMA - SDIO driver supports DMA
+    CONFIG_SDIO_MUXBUS - Set this SDIO interface if the SDIO interface
+      or hardware resources are shared with other drivers.
+    CONFIG_SDIO_WIDTH_D1_ONLY - Select 1-bit transfer mode.  Default:
+      4-bit transfer mode.
+    CONFIG_MMCSD_MULTIBLOCK_DISABLE - Use only the single block transfer method.
+      This setting is used to work around buggy SDIO drivers that cannot handle
+      multiple block transfers.
+
+  SDIO-based MMC/SD driver
+
+    CONFIG_FS_READAHEAD - Enable read-ahead buffering
+    CONFIG_FS_WRITEBUFFER - Enable write buffering
+    CONFIG_MMCSD_MMCSUPPORT - Enable support for MMC cards
+    CONFIG_MMCSD_HAVECARDDETECT - SDIO driver card detection is
+      100% accurate
+
+  RiT P14201 OLED driver
+
+    CONFIG_LCD_P14201 - Enable P14201 support
+    CONFIG_P14201_SPIMODE - Controls the SPI mode
+    CONFIG_P14201_FREQUENCY - Define to use a different bus frequency
+    CONFIG_P14201_NINTERFACES - Specifies the number of physical P14201
+      devices that will be supported.
+    CONFIG_P14201_FRAMEBUFFER - If defined, accesses will be performed
+      using an in-memory copy of the OLEDs GDDRAM.  This cost of this
+      buffer is 128 * 96 / 2 = 6Kb.  If this is defined, then the driver
+      will be fully functional. If not, then it will have the following
+      limitations:
+      - Reading graphics memory cannot be supported, and
+      - All pixel writes must be aligned to byte boundaries.
+      The latter limitation effectively reduces the 128x96 disply to 64x96.
+
+  Nokia 6100 Configuration Settings:
+
+    CONFIG_NOKIA6100_SPIMODE - Controls the SPI mode
+    CONFIG_NOKIA6100_FREQUENCY - Define to use a different bus frequency
+    CONFIG_NOKIA6100_NINTERFACES - Specifies the number of physical Nokia
+      6100 devices that will be supported.
+    CONFIG_NOKIA6100_BPP - Device supports 8, 12, and 16 bits per pixel.
+    CONFIG_NOKIA6100_S1D15G10 - Selects the Epson S1D15G10 display controller
+    CONFIG_NOKIA6100_PCF8833 - Selects the Phillips PCF8833 display controller
+    CONFIG_NOKIA6100_BLINIT - Initial backlight setting
+
+    The following may need to be tuned for your hardware:
+    CONFIG_NOKIA6100_INVERT - Display inversion, 0 or 1, Default: 1
+    CONFIG_NOKIA6100_MY - Display row direction, 0 or 1, Default: 0
+    CONFIG_NOKIA6100_MX - Display column direction, 0 or 1, Default: 1
+    CONFIG_NOKIA6100_V - Display address direction, 0 or 1, Default: 0
+    CONFIG_NOKIA6100_ML - Display scan direction, 0 or 1, Default: 0
+    CONFIG_NOKIA6100_RGBORD - Display RGB order, 0 or 1, Default: 0
+
+    Required LCD driver settings:
+    CONFIG_LCD_NOKIA6100 - Enable Nokia 6100 support
+    CONFIG_LCD_MAXCONTRAST - must be 63 with the Epson controller and 127 with
+      the Phillips controller.
+    CONFIG_LCD_MAXPOWER - Maximum value of backlight setting.  The backlight
+      control is managed outside of the 6100 driver so this value has no
+      meaning to the driver.  Board-specific logic may place restrictions on
+      this value.
+
+  Input Devices
+
+    CONFIG_INPUT
+      Enables general support for input devices
+ 
+    CONFIG_INPUT_TSC2007
+      If CONFIG_INPUT is selected, then this setting will enable building
+      of the TI TSC2007 touchscreen driver.
+    CONFIG_TSC2007_MULTIPLE
+      Normally only a single TI TSC2007 touchscreen is used.  But if
+      there are multiple TSC2007 touchscreens, this setting will enable
+      multiple touchscreens with the same driver.
+
+    CONFIG_INPUT_STMPE811
+      Enables support for the STMPE811 driver (Needs CONFIG_INPUT)
+    CONFIG_STMPE811_SPI
+      Enables support for the SPI interface (not currenly supported)
+    CONFIG_STMPE811_I2C
+      Enables support for the I2C interface
+    CONFIG_STMPE811_MULTIPLE 
+      Can be defined to support multiple STMPE811 devices on board.
+    CONFIG_STMPE811_ACTIVELOW
+      Interrupt is generated by an active low signal (or falling edge).
+    CONFIG_STMPE811_EDGE
+      Interrupt is generated on an edge (vs. on the active level)
+    CONFIG_STMPE811_NPOLLWAITERS
+      Maximum number of threads that can be waiting on poll() (ignored if 
+      CONFIG_DISABLE_POLL is set).
+    CONFIG_STMPE811_TSC_DISABLE
+      Disable driver touchscreen functionality.
+    CONFIG_STMPE811_ADC_DISABLE
+      Disable driver ADC functionality.
+    CONFIG_STMPE811_GPIO_DISABLE
+      Disable driver GPIO functionlaity.
+    CONFIG_STMPE811_GPIOINT_DISABLE
+      Disable driver GPIO interrupt functionality (ignored if GPIO
+      functionality is disabled).
+    CONFIG_STMPE811_SWAPXY
+      Reverse the meaning of X and Y to handle different LCD orientations.
+    CONFIG_STMPE811_TEMP_DISABLE
+      Disable driver temperature sensor functionality.
+    CONFIG_STMPE811_REGDEBUG
+      Enabled very low register-level debug output.  Requires CONFIG_DEBUG.
+    CONFIG_STMPE811_THRESHX and CONFIG_STMPE811_THRESHY
+      STMPE811 touchscreen data comes in a a very high rate.  New touch positions
+      will only be reported when the X or Y data changes by these thresholds.
+      This trades reduces data rate for some loss in dragging accuracy.  The
+      STMPE811 is configure for 12-bit values so the raw ranges are 0-4095. So
+      for example, if your display is 320x240, then THRESHX=13 and THRESHY=17
+      would correspond to one pixel.  Default: 12
+
+  Analog Devices
+
+    CONFIG_DAC
+      Enables general support for Digital-to-Analog conversion devices.
+    CONFIG_ADC
+      Enables general support for Analog-to-Digital conversion devices.
+    CONFIG_ADC_ADS125X
+      Adds support for the TI ADS 125x ADC.
+
+  ENC28J60 Ethernet Driver Configuration Settings:
+
+    CONFIG_ENC28J60 - Enabled ENC28J60 support
+    CONFIG_ENC28J60_SPIMODE - Controls the SPI mode
+    CONFIG_ENC28J60_FREQUENCY - Define to use a different bus frequency
+    CONFIG_ENC28J60_NINTERFACES - Specifies the number of physical ENC28J60
+      devices that will be supported.
+    CONFIG_ENC28J60_STATS - Collect network statistics
+    CONFIG_ENC28J60_HALFDUPPLEX - Default is full duplex
+
+  Networking support via uIP
+
+    CONFIG_NET - Enable or disable all network features
+    CONFIG_NET_NOINTS --  CONFIG_NET_NOINT indicates that uIP not called from
+      the interrupt level.  If CONFIG_NET_NOINTS is defined, critical sections
+      will be managed with semaphores; Otherwise, it assumed that uIP will be
+      called from interrupt level handling and critical sections will be
+      managed by enabling and disabling interrupts.
+    CONFIG_NET_MULTIBUFFER - Traditionally, uIP has used a single buffer
+      for all incoming and outgoing traffic.  If this configuration is
+      selected, then the driver can manage multiple I/O buffers and can,
+      for example, be filling one input buffer while sending another
+      output buffer.  Or, as another example, the driver may support
+      queuing of concurrent input/ouput and output transfers for better
+      performance.
+    CONFIG_NET_IPv6 - Build in support for IPv6
+    CONFIG_NSOCKET_DESCRIPTORS - Maximum number of socket descriptors
+    per task/thread.
+    CONFIG_NET_NACTIVESOCKETS - Maximum number of concurrent socket
+      operations (recv, send, etc.).  Default: CONFIG_NET_TCP_CONNS+CONFIG_NET_UDP_CONNS
+    CONFIG_NET_SOCKOPTS - Enable or disable support for socket options
+
+    CONFIG_NET_BUFSIZE - uIP buffer size
+    CONFIG_NET_TCPURGDATA - Determines if support for TCP urgent data
+      notification should be compiled in. Urgent data (out-of-band data)
+      is a rarely used TCP feature that is very seldom would be required.
+    CONFIG_NET_TCP - TCP support on or off
+    CONFIG_NET_TCP_CONNS - Maximum number of TCP connections (all tasks)
+    CONFIG_NET_MAX_LISTENPORTS - Maximum number of listening TCP ports (all tasks)
+    CONFIG_NET_TCP_READAHEAD_BUFSIZE - Size of TCP read-ahead buffers
+    CONFIG_NET_NTCP_READAHEAD_BUFFERS - Number of TCP read-ahead buffers
+      (may be zero to disable TCP/IP read-ahead buffering)
+    CONFIG_NET_TCP_RECVDELAY - Delay (in deciseconds) after a TCP/IP packet
+      is received.  This delay may allow catching of additional packets
+      when TCP/IP read-ahead is disabled.  Default: 0
+    CONFIG_NET_TCPBACKLOG - Incoming connections pend in a backlog until
+      accept() is called. The size of the backlog is selected when listen()
+      is called.
+    CONFIG_NET_UDP - UDP support on or off
+    CONFIG_NET_UDP_CHECKSUMS - UDP checksums on or off
+    CONFIG_NET_UDP_CONNS - The maximum amount of concurrent UDP
+      connections
+    CONFIG_NET_ICMP - Enable minimal ICMP support. Includes built-in support
+      for sending replies to received ECHO (ping) requests.
+    CONFIG_NET_ICMP_PING - Provide interfaces to support application level
+      support for sending ECHO (ping) requests and associating ECHO
+      replies.
+    CONFIG_NET_IGMP - Enable IGMPv2 client support.
+    CONFIG_PREALLOC_IGMPGROUPS - Pre-allocated IGMP groups are used
+      only if needed from interrupt level group created (by the IGMP server).
+      Default: 4.
+    CONFIG_NET_PINGADDRCONF - Use "ping" packet for setting IP address
+    CONFIG_NET_STATISTICS - uIP statistics on or off
+    CONFIG_NET_RECEIVE_WINDOW - The size of the advertised receiver's
+      window
+    CONFIG_NET_ARPTAB_SIZE - The size of the ARP table
+    CONFIG_NET_ARP_IPIN - Harvest IP/MAC address mappings from the ARP table
+      from incoming IP packets.
+    CONFIG_NET_BROADCAST - Incoming UDP broadcast support
+    CONFIG_NET_MULTICAST - Outgoing multi-cast address support
+
+  SLIP Driver.  SLIP supports point-to-point IP communications over a serial
+    port.  The default data link layer for uIP is Ethernet. If CONFIG_NET_SLIP
+    is defined in the NuttX configuration file, then SLIP will be supported.
+    The basic differences between the SLIP and Ethernet configurations is that
+    when SLIP is selected: 
+
+    * The link level header (that comes before the IP header) is omitted. 
+    * All MAC address processing is suppressed. 
+    * ARP is disabled.
+
+    If CONFIG_NET_SLIP is not selected, then Ethernet will be used (there is
+    no need to define anything special in the configuration file to use
+    Ethernet -- it is the default). 
+
+    CONFIG_NET_SLIP -- Enables building of the SLIP driver. SLIP requires
+      at least one IP protocols selected and the following additional
+      network settings: CONFIG_NET_NOINTS and CONFIG_NET_MULTIBUFFER.
+      CONFIG_NET_BUFSIZE *must* be set to 296.  Other optional configuration
+      settings that affect the SLIP driver: CONFIG_NET_STATISTICS. 
+      Default: Ethernet
+
+    If SLIP is selected, then the following SLIP options are available:
+
+    CONFIG_CLIP_NINTERFACES -- Selects the number of physical SLIP
+      interfaces to support.  Default: 1
+    CONFIG_SLIP_STACKSIZE -- Select the stack size of the SLIP RX and
+      TX tasks.  Default: 2048
+    CONFIG_SLIP_DEFPRIO - The priority of the SLIP RX and TX tasks.
+      Default: 128
+
+  UIP Network Utilities
+

+
+  THTTPD
+
+    CONFIG_THTTPD_PORT - THTTPD Server port number
+    CONFIG_THTTPD_IPADDR - Server IP address (no host name)
+    CONFIG_THTTPD_SERVER_ADDRESS - SERVER_ADDRESS: response
+    CONFIG_THTTPD_SERVER_SOFTWARE - SERVER_SOFTWARE: response
+    CONFIG_THTTPD_PATH - Server working directory
+    CONFIG_THTTPD_CGI_PATH - Path to CGI executables
+    CONFIG_THTTPD_CGI_PATTERN - Only CGI programs matching this
+      pattern will be executed.  In fact, if this value is not defined
+      then no CGI logic will be built.
+    CONFIG_THTTPD_CGI_PRIORITY - Provides the priority of CGI child tasks
+    CONFIG_THTTPD_CGI_STACKSIZE - Provides the initial stack size of
+      CGI child task (will be overridden by the stack size in the NXFLAT
+      header)
+    CONFIG_THTTPD_CGI_BYTECOUNT - Byte output limit for CGI tasks.

+      to run before killing them.
+    CONFIG_THTTPD_CHARSET- The default character set name to use with
+      text MIME types.
+    CONFIG_THTTPD_IOBUFFERSIZE - 
+    CONFIG_THTTPD_INDEX_NAMES - A list of index filenames to check. The
+      files are searched for in this order.
+    CONFIG_AUTH_FILE - The file to use for authentication. If this is
+      defined then thttpd checks for this file in the local directory
+      before every fetch. If the file exists then authentication is done,
+      otherwise the fetch proceeds as usual. If you leave this undefined
+      then thttpd will not implement authentication at all and will not
+      check for auth files, which saves a bit of CPU time. A typical
+      value is ".htpasswd"
+    CONFIG_THTTPD_LISTEN_BACKLOG - The listen() backlog queue length.
+    CONFIG_THTTPD_LINGER_MSEC - How many milliseconds to leave a connection
+      open while doing a lingering close.

+      cleanup job.
+    CONFIG_THTTPD_IDLE_READ_LIMIT_SEC - How many seconds to allow for
+     reading the initial request on a new connection.
+    CONFIG_THTTPD_IDLE_SEND_LIMIT_SEC - How many seconds before an
+      idle connection gets closed.
+    CONFIG_THTTPD_TILDE_MAP1 and CONFIG_THTTPD_TILDE_MAP2 - Tilde mapping.
+      Many URLs use ~username to indicate a user's home directory. thttpd
+       provides two options for mapping this construct to an  actual filename.
+      1) Map ~username to <prefix>/username. This is the recommended choice.
+        Each user gets a subdirectory in the main web tree, and the tilde
+        construct points there. The prefix could be something like "users",
+        or it could be empty.
+      2) Map ~username to <user's homedir>/<postfix>. The postfix would be
+        the name of a subdirectory off of the user's actual home dir,
+        something like "public_html".
+      You can also leave both options undefined, and thttpd will not do
+      anything special about tildes. Enabling both options is an error.
+      Typical values, if they're defined, are "users" for
+      CONFIG_THTTPD_TILDE_MAP1 and "public_html"forCONFIG_THTTPD_TILDE_MAP2. 
+    CONFIG_THTTPD_GENERATE_INDICES
+    CONFIG_THTTPD_URLPATTERN - If defined, then it will be used to match
+      and verify referrers.
+
+  FTP Server

+    CONFIG_FTPD_CMDBUFFERSIZE - The maximum size of one command.  Default:
+      128 bytes.
+    CONFIG_FTPD_DATABUFFERSIZE - The size of the I/O buffer for data
+      transfers.  Default: 512 bytes.
+    CONFIG_FTPD_WORKERSTACKSIZE - The stacksize to allocate for each
+      FTP daemon worker thread.  Default:  2048 bytes.

+      stack alignment requirements (may not be supported
+      in all architectures).
+    CONFIG_IDLETHREAD_STACKSIZE - The size of the initial stack.
+      This is the thread that (1) performs the inital boot of the system up

+
+configs/amber
+  This is placeholder for the SoC Robotics Amber Web Server that is based
+  on the Atmel AVR ATMega128 MCU.  There is not much there yet and what is
+  there is untested due to tool-related issues.
+
+configs/avr32dev1
+  This is a port of NuttX to the Atmel AVR32DEV1 board.  That board is
+  based on the Atmel AT32UC3B0256 MCU and uses a specially patched
+  version of the GNU toolchain:  The patches provide support for the
+  AVR32 family.  That patched GNU toolchain is available only from the

+
+Configuring NuttX
+^^^^^^^^^^^^^^^^^
+
+Configuring NuttX requires only copying
+
+  configs/<board-name>/<config-dir>/Make.def to ${TOPDIR}/Make.defs
+  configs/<board-name>/<config-dir>/setenv.sh to ${TOPDIR}/setenv.sh
+  configs/<board-name>/<config-dir>/defconfig to ${TOPDIR}/.config
+
+And if configs/<board-name>/<config-dir>/appconfig exists in the board
+configuration directory:
+
+  Copy configs/<board-name>/<config-dir>/appconfig to <app-dir>/.config
+  echo "APPS_LOC=\"<app-dir>\"" >> "${TOPDIR}/.config"
+
+tools/configure.sh
+  There is a script that automates these steps.  The following steps will
+  accomplish the same configuration:
+
+  cd tools
+  ./configure.sh <board-name>/<config-dir>
+
+And if configs/<board-name>/<config-dir>/appconfig exists and your
+application directory is not in the standard loction (../apps), then
+you should also specify the location of the application directory on the
+command line like:
+  
+  cd tools
+  ./configure.sh -a <app-dir> <board-name>/<config-dir>
+
+Building Symbol Tables
+^^^^^^^^^^^^^^^^^^^^^^
+
+Symbol tables are needed at several of the binfmt interfaces in order to bind
+a module to the base code.  These symbol tables can be tricky to create and
+will probably have to be tailored for any specific application, balancing
+the number of symbols and the size of the symbol table against the symbols
+required by the applications.
+
+The top-level System.map file is one good source of symbol information
+(which, or course, was just generated from the top-level nuttx file
+using the GNU 'nm' tool).
+
+There are also common-separated value (CSV) values in the source try that
+provide information about symbols.  In particular:
+
+  nuttx/syscall/syscall.csv - Describes the NuttX RTOS interface, and
+  nuttx/lib/lib.csv         - Describes the NuttX C library interface.
+
+There is a tool at nuttx/tools/mksymtab that will use these CSV files as
+input to generate a generic symbol table.  See nuttx/tools/README.txt for
+more information about using the mksymtab tool.

+Toolchains
+^^^^^^^^^^
+
+Buildroot:
+
+  There is a DIY buildroot version for the AVR boards here:
+  http://sourceforge.net/projects/nuttx/files/buildroot/.  See the
+  following section for details on building this toolchain.
+
+  It is assumed in some places that buildroot toolchain is available
+  at ../misc/buildroot/build_avr.  Edit the setenv.sh file if
+  this is not the case.
+
+  After configuring NuttX, make sure that CONFIG_AVR_BUILDROOT=y is set in your
+  .config file.
+
+WinAVR:
+
+  For Cygwin development environment on Windows machines, you can use
+  WinAVR: http://sourceforge.net/projects/winavr/files/
+
+  It is assumed in some places that WinAVR is installed at C:/WinAVR.  Edit the
+  setenv.sh file if this is not the case.
+
+  After configuring NuttX, make sure that CONFIG_AVR_WINAVR=y is set in your
+  .config file.
+
+  WARNING:  There is an incompatible version of cygwin.dll in the WinAVR/bin
+  directory!  Make sure that the path to the correct cygwin.dll file precedes
+  the path to the WinAVR binaries!
+
+Linux:
+
+  For Linux, there are widely available avr-gcc packages.  On Ubuntu, use:
+  sudo apt-get install gcc-avr gdb-avr avr-libc
+
+  After configuring NuttX, make sure that CONFIG_AVR_LINUXGCC=y is set in your
+  .config file.
+
+Windows Native Toolchains
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  The WinAVR toolchain is a Windows native toolchain. There are several
+  limitations to using a Windows native toolchain in a Cygwin environment. 
+  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath'
+     utility but you might easily find some new path problems.  If so, check
+     out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic
+     links are used in Nuttx (e.g., include/arch).  The make system works
+     around these  problems for the Windows tools by copying directories
+     instead of linking them.  But this can also cause some confusion for
+     you:  For example, you may edit a file in a "linked" directory and find
+     that your changes had no effect. That is because you are building the
+     copy of the file in the "fake" symbolic directory.  If you use a
+     Windows toolchain, you should get in the habit of making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This
+     is because the dependencies are generated using Windows pathes which do
+     not work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native
+     toolchains.  That support can be enabled by modifying your Make.defs
+     file as follows:
+
+    -  MKDEP = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are
+     not building on C:), then you may need to modify tools/mkdeps.sh
+
+  An additional issue with the WinAVR toolchain, in particular, is that it
+  contains an incompatible version of the Cygwin DLL in its bin/ directory.
+  You must take care that the correct Cygwin DLL is used.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  If NuttX buildroot toolchain source tarball cne can be downloaded from the
+  NuttX SourceForge download site (https://sourceforge.net/projects/nuttx/files/).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh amber/<sub-dir>
+
+     NOTE: you also must copy avr-libc header files into the NuttX include
+     directory with command perhaps like:
+
+     cp -a /cygdrive/c/WinAVR/include/avr include/.
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/avr-defconfig-4.5.2 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you
+  are building a toolchain for Cygwin under Windows.
+
+avr-libc
+^^^^^^^^
+
+Header Files
+
+  In any case, header files from avr-libc are required:  http://www.nongnu.org/avr-libc/.
+  A snapshot of avr-lib is included in the WinAVR installation. For Linux
+  development platforms, avr-libc package is readily available (and would
+  be installed in the apt-get command shown above).  But if you are using
+  the NuttX buildroot configuration on Cygwin, then you will have to build
+  get avr-libc from binaries.
+
+Header File Installation
+
+  The NuttX build will required that the AVR header files be available via
+  the NuttX include directory.  This can be accomplished by either copying
+  the avr-libc header files into the NuttX include directory:
+
+  cp -a <avr-libc-path>/include/avr <nuttx-path>/include/.
+
+  Or simply using a symbolic link:
+
+  ln -s <avr-libc-path>/include/avr <nuttx-path>/include/.
+
+Build Notes:
+
+  It may not necessary to have a built version of avr-lib; only header files
+  are required.  Bu if you choose to use the optimized libraru functions of
+  the flowing point library, then you may have to build avr-lib from sources.
+  Below are instructions for building avr-lib from fresh sources:
+
+  1. Download the avr-libc package from: 
+
+     http://savannah.nongnu.org/projects/avr-libc/
+
+     I am using avr-lib-1.7.1.tar.bz2
+
+  2. Upack the tarball and cd into the 
+ 
+     tar jxf avr-lib-1.7.1.tar.bz2
+     cd avr-lib-1.7.1
+
+  3. Configure avr-lib.  Assuming that WinAVR is installed at the following
+     loction:
+
+     export PATH=/cygdrive/c/WinAVR/bin:$PATH
+     ./configure --build=`./config.guess` --host=avr
+
+     This takes a *long* time.
+
+  4. Make avr-lib.
+
+     make
+
+     This also takes a long time because it generates variants for nearly
+     all AVR chips.
+
+  5. Install avr-lib.
+
+     make install
+
+Amber Web Server Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+    CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+       be set to:
+
+       CONFIG_ARCH=avr
+
+    CONFIG_ARCH_family - For use in C code:
+
+       CONFIG_ARCH_AVR=y
+
+    CONFIG_ARCH_architecture - For use in C code:
+
+       CONFIG_ARCH_ATMEGA=y
+
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+       CONFIG_ARCH_CHIP=atmega
+
+    CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+       chip:
+
+       CONFIG_ARCH_CHIP_ATMEGA128=y
+
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+
+       CONFIG_ARCH_BOARD=amber
+
+    CONFIG_ARCH_BOARD_name - For use in C code
+
+       CONFIG_ARCH_BOARD_AMBER=y
+
+    CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+       of delay loops
+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_DRAM_SIZE - Describes the installed DRAM.  One of:
+
+       CONFIG_DRAM_SIZE=(8*1024) - (8Kb)
+
+    CONFIG_DRAM_START - The start address of installed SRAM
+
+       CONFIG_DRAM_START=0x800100
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+       stack. If defined, this symbol is the size of the interrupt
+        stack in bytes.  If not defined, the user task stacks will be
+      used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.
+
+    Individual subsystems can be enabled:

+       CONFIG_AVR_USART1=n
+       CONFIG_AVR_ADC=n
+       CONFIG_AVR_ANACOMP=n
+       CONFIG_AVR_TWI=n
+
+   If the watchdog is enabled, this specifies the initial timeout.  Default
+  is maximum supported value.

+    CONFIG_USARTn_TXBUFSIZE - Characters are buffered before
+       being sent.  This specific the size of the transmit buffer
+    CONFIG_USARTn_BAUD - The configure BAUD of the USART.  Must be
+    CONFIG_USARTn_BITS - The number of bits.  Must be either 7 or 8.
+    CONFIG_USARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
+    CONFIG_USARTn_2STOP - Two stop bits

+GPIO Pin Configuration
+^^^^^^^^^^^^^^^^^^^^^^
+
+The only GPIO pin usage is for LEDs (2) and Buttons (2):
+
+  PIN 13  PA7  LED1
+  PIN 14  PA8  LED2
+  PIN 24  PB2  KEY1
+  PIN 25  PB3  KEY2
+
+(See configs/avr32dev/src/avr32dev_internal.h).  And also for
+crystals (4), JTAG (1), and USB (1):
+
+  PIN 30  PA11 XIN32
+  PIN 31  PA12 XOUT32
+  PIN 35  PA15 EVTO (JTAG)
+  PIN 39  PA18 X1IN
+  PIN 40  PA19 X1OUT
+  PIN 61  PA26 ID (USB)
+
+All GPIO pins are brought out through connectors J1 (PINS 33-64)
+and J2 (PINS 1-32).
+
+NOTE:  There seems to be some difference in labeling for OSC0 and
+OSC1 between MCUZone.com and Atmel:
+
+  Oscillator pinout
+  -------------------------- --------------------
+  QFP48 QFP64 Pad Oscillator AVR32DEV1
+   PIN   PIN       PIN       LABEL
+  ----- ----- ---- --------- --------------------
+   30    39   PA18 XIN0      X1IN   (12MHz)
+         41   PA28 XIN1      PA28   (no crystal)
+   22    30   PA11 XIN32     XIN32  (32KHz)
+   31    40   PA19 XOUT0     X1OUT  (12Mhz)
+         42   PA29 XOUT1     PA29   (no crystal)
+   23    31   PA12 XOUT32    XOUT32 (32 Khz)
+  ----- ----- ---- --------- --------------------
+
+NOTE 1: These crystal inputs/outputs are analog signals and my
+assumption is that they need no pin multiplexing setting to
+enable them for the external crystal function.
+
+NOTE 2: There is no support for OSC1.
+
+NOTE 3: There are solder pads for the 32KHz OSC32, but the
+crystal is not populated on my board.  Therefore, the RTC will
+have to run from the (uncalibrated) RCOSC.
+
+Serial Connection
+^^^^^^^^^^^^^^^^^
+
+USART1 is the default USART1 used in the configuration files to
+provide a serial console (of course, that can be easily changed
+by editting the configuration file).  The AVR32DEV1 board has no
+RS-232 drivers or connectors on board.  I use an off-board MAX232
+module that I got on eBay (search for MAX232 if you want to find
+one).  I connect the MAX232 board as follows:
+
+In configs/avr32dev/include/board.h:
+
+  #define PINMUX_USART1_RXD   PINMUX_USART1_RXD_1
+  #define PINMUX_USART1_TXD   PINMUX_USART1_TXD_1
+
+In arch/avr/src/at32uc3/at32uc3b_pinmux.h:
+
+  #define PINMUX_USART1_RXD_1 (GPIO_PERIPH | GPIO_FUNCD | GPIO_PORTA | 17)
+  #define PINMUX_USART1_TXD_1 (GPIO_PERIPH | GPIO_FUNCA | GPIO_PORTA | 23)
+
+PA17 and PA23 are avaiable from the AVR32DEV1:
+
+  FUNC GPIO  PIN   Header 16X2 (J1) MX232 Board
+  ---- ----- ----- ---------------- ------------
+  RXD  PA17  PIN37 Pin 5            PIN4 RXD (5V TTL/CMOS)
+  TXD  PA23  PIN47 Pin 15           PIN3 TXD (5V TTL/CMOS)
+                                    PIN2 GND
+                                    PIN1 VCC (5V)
+
+  Voltage on GPIO Pins with respect to Ground for TCK, RESET_N, PA03-PA08,
+  PA11-PA12, PA18-PA19, PA28-PA31............................-0.3 to 3.6V
+  Other Pins ............................................... -0.3 to 5.5V
+
+  I get the 5V from another USB port (using the 5V power cable that normally
+  provides the extra current needed by my USB IDE drive).
+
+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment.
+
+GNU Toolchains
+^^^^^^^^^^^^^^
+
+Atmel Toolchain:
+
+  The build logic in these directories assume that you are using the GNU
+  toolchain with the Atmel patches.  The patch file, pre-patched tool
+  sources,and pre-built binaries are available from the Atmel website.
+
+    CONFIG_AVR32_AVRTOOLSW=y  # Use the windows version
+    CONFIG_AVR32_AVRTOOLSL=y  # Ue the Linux version
+
+  NOTE: The NuttX builtroot cannot be used to build the AVR32 toolchain.
+  This is because the Atmel patches that add support for the AVR32 are not
+  included in the NuttX buildroot.
+
+WinAVR:
+
+  Another option for use under Windows is WinAVR:
+  http://sourceforge.net/projects/winavr/files/.  WinAVR includes the
+  AVR32 toolchain as well as the AVR toolchain and various support
+  libraries and header files.
+
+IDEs
+^^^^
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project.
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/avr/src/at32uc3,
+     arch/avr/src/common, arch/arm/src/avr, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/avr/src/avr3/up_nommuhead.S.
+
+AVR32 Bootloader
+^^^^^^^^^^^^^^^^
+
+  Boot Sequence
+  -------------
+  
+    "An AVR UC3 part having the bootloader programmed resets as any other
+     part at 80000000h. Bootloader execution begins here. The bootloader
+     first performs the boot process to know whether it should start the
+     USB DFU ISP or the application. If the tested conditions indicate
+     that the USB DFU ISP should be started, then execution continues in
+     the bootloader area, i.e. between 80000000h and 80002000h, else
+     the bootloader launches the application at 80002000h."
+  
+  Link Address
+  ------------
+
+  The linker scripts (ld.script) assume that you are using the DFU
+  bootloader.  The bootloader resides at 0x8000:0000 and so the ld.script
+  files link the application to execute after the bootloader at
+  0x8000:2000. To link so that NuttX boots directly without using the
+  bootloader, change the flash definition from:
+
+    flash (rxai!w)  : ORIGIN = 0x80002000, LENGTH = 256K - 8K
+
+  to:
+    flash (rxai!w)  : ORIGIN = 0x80000000, LENGTH = 256K
+
+  Or to use the MSC bootloader:
+
+    flash (rxai!w)  : ORIGIN = 0x80008000, LENGTH = 256K - 32K
+
+  Entering the ISP
+  ----------------
+
+  In order to use the USB port to download the FLASH(ISP), you need to
+  use the S3(PA13) to make CPU return to boot status. In this mode, the
+  on chip bootloader will run, making the ISP possible.
+
+  BatchISP
+  --------
+
+  Unlike other Atmel parts, the AVR32 will not work with the FLIP GUI
+  program.  Instead, you must use the command-line loader call BatchISP.
+  If need to download FLIP from the atmel.com website, install the USB
+  driver in the FLIP usb directory.  Then in the bin directory where
+  you installed FLIP, you will also find batchisp.exe.
+
+  NOTE: The AVR32DEV1 setenv.sh files will add the path to the BatchISP
+  bin directory to the Cygwin PATH variable.  If you use a different
+  version of FLIP or if you install FLIP in a different location, you
+  will need to modify the setenv.sh files.
+
+  Notes from "AVR32 UC3 USB DFU Bootloader" (doc7745.pdf)
+  
+  "To launch BatchISP, open a command prompt. Windows or Cygwin command
+   prompt can be used provided that the bin folder of the FLIP installation
+   directory is in the PATH (Windows’ or Cygwin’s) environment variable.
+   When running BatchISP on AT32UC3xxxxx, the target part has to be specified
+   with -device at32uc3xxxxx and the communication port with -hardware usb.
+   Commands can then be placed after -operation. These commands are executed
+   in order. BatchISP options can be placed in a text file invoked using
+   -cmdfile rather than on the command line.
+
+  "BatchISP works with an internal ISP buffer per target memory. These ISP
+   buffers can be filled from several sources. All target operations (program,
+   verify, read) are performed using these buffers."
+ 
+  The following BatchISP command line will erase FLASH, write the nuttx binary
+  into FLASH, and reset the AVR32.  This command line is available in the
+  script config/avr32dev1/tools/doisp.sh:
+
+     batchisp -device at32uc3b0256 -hardware usb -operation erase f memory flash \
+     blankcheck loadbuffer nuttx.elf program verify start reset 0
+
+  "BatchISP main commands available on AT32UC3xxxxx are:
+  
+   - ASSERT { PASS | FAIL } changes the displayed results of the following
+     operations according to the expected behavior.
+   - ONFAIL { ASK | ABORT | RETRY | IGNORE } changes the interactive behavior
+     of BatchISP in case of failure.
+   - WAIT <Nsec> inserts a pause between two ISP operations.
+   - ECHO <comment> displays a message.
+   - ERASE F erases internal flash contents, except the bootloader.
+   - MEMORY { FLASH | SECURITY | CONFIGURATION | BOOTLOADER | SIGNATURE | USER }
+     selects a target memory on which to apply the following operations.
+   - ADDRANGE <addrMin> <addrMax> selects in the current target memory an
+     address range on which to apply the following operations.
+   - BLANKCHECK checks that the selected address range is erased.
+   - FILLBUFFER <data> fills the ISP buffer with a byte value.
+   - LOADBUFFER { <in_elffile> | <in_hexfile> } loads the ISP buffer from an
+     input file.
+   - PROGRAM programs the selected address range with the ISP buffer.
+   - VERIFY verifies that the selected address range has the same contents
+     as the ISP buffer.
+   - READ reads the selected address range to the ISP buffer.
+   - SAVEBUFFER <out_hexfile> { HEX386 | HEX86 } saves the ISP buffer to an
+      output file.
+   - START { RESET | NORESET } 0 starts the execution of the programmed
+     application with an optional hardware reset of the target.
+
+  "The AT32UC3xxxxx memories made available by BatchISP are:
+
+  - FLASH: This memory is the internal flash array of the target, including the
+    bootloader protected area. E.g. on AT32UC3A0512 (512-kB internal flash),
+    addresses from 0 to 0x7FFFF can be accessed in this memory.
+  - SECURITY: This memory contains only one byte. The least significant bit
+    of this byte reflects the value of the target Security bit which can only
+    be set to 1. Once set, the only accepted commands will be ERASE and START.
+    After an ERASE command, all commands are accepted until the end of the
+    non-volatile ISP session, even if the Security bit is set.
+  - CONFIGURATION: This memory contains one byte per target general-purpose
+    fuse bit.  The least significant bit of each byte reflects the value of
+    the corresponding GP fuse bit.
+  - BOOTLOADER: This memory contains three bytes concerning the ISP: the ISP
+    version in BCD format without the major version number (always 1), the
+    ISP ID0 and the ISP ID1.
+  - SIGNATURE: This memory contains four bytes concerning the part: the product
+    manufacturer ID, the product family ID, the product ID and the product
+    revision.
+  - USER: This memory is the internal flash User page of the target, with
+    addresses from 0 to 0x1FF.
+
+  "For further details about BatchISP commands, launch batchisp -h or see the
+   help files installed with FLIP ..."
+
+Reset
+^^^^^
+
+   I don't trust the reset button -- if you reset and something weird happens,
+   try a full power cycle.
+
+Make Tip
+^^^^^^^^
+
+   Because this build uses a native Windows toolchain and the native Windows
+   tools do not understand Cygwin's symbolic links, the NuttX make system does
+   something weird:  It copies the configuration directories instead of linking
+   to them (it could, perhaps, use the NTFS 'mklink' command, but it doesn't).
+
+   A consequence of this is that you can easily get confused when you edit
+   a file in one of the "linked" directories, re-build NuttX, and then not see your
+   changes when you run the program.  That is because build is still using the
+   version of the file in the copied directory, not your modified file! To work
+   around this annoying behavior, do the following when you re-build:
+   
+   make clean_context all <-- Remove and re-copy all of the directories, then make all
+   doisp.sh               <-- Load the code onto the board.
+
+AVR32DEV1 Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+    CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+       be set to:
+
+       CONFIG_ARCH=avr
+
+    CONFIG_ARCH_family - For use in C code:
+
+       CONFIG_ARCH_AVR=y
+
+    CONFIG_ARCH_architecture - For use in C code:
+
+       CONFIG_ARCH_AVR32=y
+
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+       CONFIG_ARCH_CHIP=at32uc3
+
+    CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+       chip:
+
+       CONFIG_ARCH_CHIP_AT32UC3B0256
+
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+
+       CONFIG_ARCH_BOARD=avr32dev1 (for the AV32DEV1 board)
+
+    CONFIG_ARCH_BOARD_name - For use in C code
+
+       CONFIG_ARCH_BOARD_AVR32DEV1
+
+    CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+       of delay loops
+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_DRAM_SIZE - Describes the installed DRAM (SRAM in this case):
+
+       CONFIG_DRAM_SIZE=0x00010000 (64Kb)
+
+    CONFIG_DRAM_START - The start address of installed DRAM
+
+       CONFIG_DRAM_START=0x20000000
+
+    CONFIG_ARCH_IRQPRIO - The AT32UC3B0256 supports interrupt prioritization
+
+       CONFIG_ARCH_IRQPRIO=y
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+       stack. If defined, this symbol is the size of the interrupt
+        stack in bytes.  If not defined, the user task stacks will be
+      used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.
+
+  Individual subsystems can be enabled:
+  
+    CONFIG_AVR32_GPIOIRQ - GPIO interrupt support
+    CONFIG_AVR32_GPIOIRQSETA - Set of GPIOs on PORTA that support interrupts
+    CONFIG_AVR32_GPIOIRQSETB - Set of GPIOs on PORTB that support interrupts
+
+    CONFIG_AVR32_USARTn - Enable support for USARTn
+    CONFIG_AVR32_USARTn_RS232 - Configure USARTn as an RS232 interface.
+    CONFIG_AVR32_USARTn_SPI - Configure USARTn as an SPI interface.

+    CONFIG_AVR32_USARTn_MODEM - Configure USARTn as an Modem interface.
+    CONFIG_AVR32_USARTn_IRDA - Configure USARTn as an IRDA interface.
+    CONFIG_AVR32_USARTn_ISO786 - Configure USARTn as an ISO786 interface.
+
+  AT32UC3B0256 specific device driver settings
+
+    CONFIG_USARTn_SERIAL_CONSOLE - selects the USARTn for the
+       console and ttys0 (default is the USART0).
+    CONFIG_USARTn_RXBUFSIZE - Characters are buffered as received.
+       This specific the size of the receive buffer
+    CONFIG_USARTn_TXBUFSIZE - Characters are buffered before
+       being sent.  This specific the size of the transmit buffer
+    CONFIG_USARTn_BAUD - The configure BAUD of the USART.  Must be
+    CONFIG_USARTn_BITS - The number of bits.  Must be either 7 or 8.
+    CONFIG_USARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
+    CONFIG_USARTn_2STOP - Two stop bits
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each Stellaris LM3S6965 Evaluation Kit configuration is maintained in a
+sudirectory and can be selected as follow:
+
+    cd tools
+    ./configure.sh avr32dev1/<subdir>
+    cd -
+    . ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  nsh:
+    Configures the NuttShell (nsh) located at examples/nsh.  The
+    Configuration enables only the serial NSH interface.
+
+  ostest:
+    This configuration directory, performs a simple OS test using
+    examples/ostest.
+
+    NOTE: Round-robin scheduling is disabled in this test because
+    the RR test in examples/ostest declares data structures that
+    are too large for the poor little uc3 SRAM.

+
+Toolchain
+^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the SH toolchain (if
+  different from the default).
+
+  If you have no SH toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+
+  1. You must have already configured Nuttx in <some-dir>nuttx.
+
+     cd tools
+     ./configure.sh c5471evm/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/arm-defconfig .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h so that the PATH variable includes the path to the
+     newly built binaries.
+
+ARM/C5471-specific Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+	   be set to:
+
+	   CONFIG_ARCH=arm
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_ARM=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_ARM7TDMI=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=c5471
+
+	CONFIG_ARCH_CHIP_name - For use in C code
+
+	   CONFIG_ARCH_CHIP_C5471
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=c5471evm (for the Spectrum Digital C5471 EVM)
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_C5471EVM (for the Spectrum Digital C5471 EVM)
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_ROM_VECTORS - should be defined for the C5471 because the
+	   interrupt vectors are in ROM
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	   stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.
+
+  C5471 specific device driver settings
+
+	CONFIG_SERIAL_IRDA_CONSOLE - selects the IRDA UART for the
+	   console ant ttys0 (default is the modem UART).
+	CONFIG_UART_*_HWFLOWCONTROL - enables hardware flow control
+	CONFIG_UART_*_RXBUFSIZE - Characters are buffered as received.
+	   This specific the size of the receive buffer
+	CONFIG_UART_*_TXBUFSIZE - Characters are buffered before
+	   being sent.  This specific the size of the transmit buffer
+	CONFIG_UART_*_BAUD - The configure BAUD of the UART.  Must be
+	CONFIG_UART_*_BITS - The number of bits.  Must be either 7 or 8.
+	CONFIG_UART_*_PARTIY - 0=no parity, 1=odd parity, 2=even parity
+	CONFIG_UART_*_2STOP - Two stop bits
+
+  C5471 Ethernet Driver settings
+
+	CONFIG_C5471_NET_STATS
+	CONFIG_C5471_ETHERNET_PHY={ETHERNET_PHY_LU3X31T_T64,ETHERNET_PHY_AC101L}
+	CONFIG_NET_C5471_AUTONEGOTIATION
+	CONFIG_NET_C5471_BASET100
+	CONFIG_NET_C5471_BASET10
+
+defconfig
+^^^^^^^^^
+The default configuration file, defconfig, performs a
+simple OS test using examples/ostest.  This can be
+configuration as follows:
+
+	cd tools
+	./configure.sh c5471evm
+	cd -
+	. ./setenv.sh
+
+netconfig
+^^^^^^^^^
+This alternative configuration file, netconfig, may be used
+instead of the default configuration (defconfig). This
+configuration enables networking using the c5471's built-in
+Ethernet interface.  It uses examples/nettest to excercise
+the TCP/IP network.
+
+nshconfig
+^^^^^^^^^
+This configuration file builds NSH (examples/nsh) using the
+TELNET server front end
+
+dhcpconfig
+^^^^^^^^^^
+This configuration exercises the DHCP client of netutils/dhcpc
+using examples/uip.
+
+These alternative configurations can be selected by (using
+uipconfig as example):
+
+	(Seleted the default configuration as show above)
+	cp config/c5471evm/uiponfig .config

+compal_e88
+==========
+
+This directory contains the board support for compal e88 phones.
+
+This port is based on patches contributed by Denis Carikli for both the
+compal e99 and e88. At the time of initial check-in, the following phones
+were tested:
+
+* motorolla c155 (compal e99) with the compalram and highram configuration
+* motorolla W220 (compal e88)
+* The openmoko freerunner baseband(compal e88)
+
+The patches were made by Alan Carvalho de Assis and Denis Carikli using
+the Stefan Richter's patches that can be found here:
+
+http://cgit.osmocom.org/cgit/nuttx-bb/log/?h=lputt%2Ftesting
+
+Osmocom-BB Dependencies and Sercomm
+===================================
+
+The build environment assumes that you have the osmocom-bb project
+directory at same level as the nuttx project:
+
+  |- nuttx
+  |- apps
+  `- osmocom-bb
+
+If you attempt to build this configuration without osmocom-bb, and that
+you added support for sercomm in your configuration(CONFIG_SERCOMM_CONSOLE=y) 
+you will get compilation errors in drivers/sercomm due to header files that 
+are needed from the osmocom-bb directory.
+
+By default, NuttX will not use sercomm (HDLC protocol) to communicate with 
+the host system. Sercomm is the transport used by osmocom-bb that runs on top
+of serial.  See http://bb.osmocom.org/trac/wiki/nuttx-bb/run for detailed
+the usage of nuttx with sercomm.
+
+Loading NuttX
+=============
+
+The osmocom-bb wiki describes how to load NuttX.  See
+http://bb.osmocom.org/trac/wiki/nuttx-bb for detailed information.
+The way that nuttx is loaded depends on the configuration (highram/compalram)
+and phone:
+
+o compalram is for the ramloader(for phone having a bootloader on flash)
+o highram is for phones having the romloader(if the phone has a bootrom)
+  or for loading in the ram trough a special loader(loaded first on ram
+  by talking to the ramloader) when having a ramloader(which can only
+  load 64k).

+compal_e99
+==========
+
+This directory contains the board support for compal e99 phones.
+
+This port is based on patches contributed by Denis Carikli for both the
+compal e99 and e88. At the time of initial check-in, the following phones
+were tested:
+
+* motorolla c155 (compal e99) with the compalram and highram configuration
+* motorolla W220 (compal e88)
+* The openmoko freerunner baseband(compal e88)
+
+The patches were made by Alan Carvalho de Assis and Denis Carikli using
+the Stefan Richter's patches that can be found here:
+
+http://cgit.osmocom.org/cgit/nuttx-bb/log/?h=lputt%2Ftesting
+
+Osmocom-BB Dependencies and Sercomm
+===================================
+
+The build environment assumes that you have the osmocom-bb project
+directory at same level as the nuttx project:
+
+  |- nuttx
+  |- apps
+  `- osmocom-bb
+
+If you attempt to build this configuration without osmocom-bb, and that
+you added support for sercomm in your configuration(CONFIG_SERCOMM_CONSOLE=y) 
+you will get compilation errors in drivers/sercomm due to header files that 
+are needed from the osmocom-bb directory.
+
+By default, NuttX will not use sercomm (HDLC protocol) to communicate with 
+the host system. Sercomm is the transport used by osmocom-bb that runs on top
+of serial.  See http://bb.osmocom.org/trac/wiki/nuttx-bb/run for detailed
+the usage of nuttx with sercomm.
+
+Loading NuttX
+=============
+
+The osmocom-bb wiki describes how to load NuttX.  See
+http://bb.osmocom.org/trac/wiki/nuttx-bb for detailed information.
+The way that nuttx is loaded depends on the configuration (highram/compalram)
+and phone:
+
+o compalram is for the ramloader(for phone having a bootloader on flash)
+o highram is for phones having the romloader(if the phone has a bootrom)
+  or for loading in the ram trough a special loader(loaded first on ram
+  by talking to the ramloader) when having a ramloader(which can only
+  load 64k).

+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development
+  environment. The source has been built only using the GNU toolchain
+  (see below).  Other toolchains will likely cause problems.
+
+NuttX Buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the HC12 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no HC12 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin
+  environments.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh demo9s12nec64/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/m9s12x-defconfig-3.3.6 .config
+
+  6. make oldconfig
+
+  7. make
+
+     If the make fails because it can't find the file to download, you may
+     have to locate the file on the internet and download it into the archives/
+     directory manually.  For example, binutils-2.18 can be found here:
+     http://ftp.gnu.org/gnu/binutils/
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you are
+  building a Cortex-M3 toolchain for Cygwin under Windows.
+
+FreeScale HCS12 Serial Monitor
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  General:
+    The NuttX HCS12 port is configured to use the Freescale HCS serial
+    monitor.  This monitor supports primitive debug commands that allow
+    FLASH/EEPROM programming and debugging through an RS-232 serial
+    interface.  The serial monior is 2Kb in size and resides in FLASH at
+    addresses 0xf800-0xffff.  The monitor does not use any RAM other than
+    the stack itself.
+
+  AN2458
+    The serial monitor is described in detail in Freescale Application
+    Note AN2458.pdf.
+
+  COP:
+    The serial monitor uses the COP for the cold reset function and should
+    not be used by the application without some precautions (see AN2458).
+
+  Clocking:
+    The serial monitor sets the operating frequency to 24 MHz.  This is
+    not altered by the NuttX start-up; doing so would interfere with the
+    operation of the serial monitor.
+
+  Memory Configuration:
+    Registers:
+    • Register space is located at 0x0000–0x03ff.
+    FLASH:
+    • FLASH memory is any address greater than 0x4000. All paged
+      addresses are assumed to be FLASH memory.
+    • Application code should exclude the 0xf780–0xff7f memory.
+    SRAM:
+    • RAM ends at 0x3FFF and builds down to the limit of the device’s
+      available RAM.
+    • The serial monitor's stack pointer is set to the end of RAM+1
+      (0x4000).
+    EEPROM:
+    • EEPROM (if the target device has any) is limited to the available
+      space between the registers and the RAM (0x0400–to start of RAM).
+    External Devices:
+    • External devices attached to the multiplexed external bus
+      interface are not supported
+
+  Serial Communications:
+    The serial monitor uses RS-232 serial communications through SCI0 at
+    115,200 baud. The monitor must have exclusive use of this interface.
+    Access to the serial port is available through a monitor jump table.
+
+  Interrrupts:
+    The serial monitor redirects interrupt vectors to an unprotected
+    portion of FLASH just before the protected monitor program
+    (0xf780–0xf7fe).  The monitor will automatically redirect vector
+    programming operations to these user vectors.  The user code should
+    therefore keep the normal (non-monitor) vector locations
+    (0xff80–0xfffe).
+
+Soft Registers
+^^^^^^^^^^^^^^
+
+  The mc68hcs12 compilation is prone to errors like the following:
+
+    CC:  lib_b16sin.c
+    lib_b16sin.c: In function `b16sin':
+    lib_b16sin.c:110: error: unable to find a register to spill in class `S_REGS'
+    lib_b16sin.c:110: error: this is the insn:
+    (insn:HI 41 46 44 8 (parallel [
+                (set (subreg:SI (reg:DI 58 [ rad ]) 4)
+                    (reg/v:SI 54 [ rad ]))
+                (clobber (scratch:HI))
+            ]) 20 {movsi_internal} (insn_list 46 (nil))
+        (expr_list:REG_UNUSED (scratch:HI)
+            (expr_list:REG_NO_CONFLICT (reg/v:SI 54 [ rad ])
+                (nil))))
+    lib_b16sin.c:110: confused by earlier errors, bailing out
+
+  There are several ways that this error could be fixed:
+
+  1. Increase the number of soft registers (i.e., "fake" registers defined
+     at fixed memory locations).  This can be done by adding something like
+     -msoft-reg-count=4 to the CFLAGS.  This approach was not taken
+     because:
+
+     - This slows hcs12 performance
+     - All of these soft registers wouil have to be saved and restored
+       on every interrupt and context switch.
+
+  2. Lowering the optimization level by dropping -Os to -O2 or, more likely,
+     by removing -fomit-frame-pointer.  Also not desireable becauase 99% of the
+     files that do not have this problem also increase in size.  Special case
+     compilation with reduced optimization levels just for the files that need
+     it could be done, but this would complicate the make system.
+
+  3. Restructuring files to reduce the complexity.  If you add local variables
+     to hold intermediate computational results, this error can be eliminated.
+     This is the approach taken in NuttX.  It has disadvantages only in that
+     (1) it takes some effort and good guessing to eliminate the problem, and (2)
+     the problem is not really eliminated -- it can and will re-occur when files
+     are changed or new files are added.
+
+  4. Many files are built that are needed by DEM09S12NE64.  Another very simple
+     option if those problem files are needed is to just remove the offending
+     files from the Make.defs file so that they no longer cause a problem.
+
+HCS12/DEMO9S12NEC64-specific Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+	   be set to:
+
+	   CONFIG_ARCH=hc
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_HC=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_HCS12=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=mc92s12nec64
+
+	CONFIG_ARCH_CHIP_name - For use in C code
+
+	   CONFIG_ARCH_CHIP_MCS92S12NEC64
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=demo9s12nec64
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_DEMOS92S12NEC64 (for the Freescale DEMO9S12NE64 development board)
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - Describes the installed RAM.
+
+	CONFIG_DRAM_START - The start address of installed RAM
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	   stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.
+
+  GPIO Interrupts
+  
+    CONFIG_GPIO_IRQ - Enable general support for GPIO IRQs
+    CONFIG_HCS12_PORTG_INTS - Enable PortG IRQs

+    CONFIG_HCS12_PORTJ_INTS - Enable PortJ IRQs
+   
+  HCS12 build options:
+
+	CONFIG_HCS12_SERIALMON - Indicates that the target systems uses
+	  the Freescale serial bootloader.
+
+	CONFIG_HCS12_NONBANKED - Indicates that the target systems does not
+	  support banking.  Only short calls are made; one fixed page is
+	  presented the the paging window.  Only 48Kb of FLASH is usable
+	  in this configuration: pages 3e, 3d, then 3f will appear as a
+	  contiguous address space in memory.
+
+  HCS12 Sub-system support
+
+	CONFIG_HCS12_SCI0
+	CONFIG_HCS12_SCI1
+
+  HCS12 specific device driver settings:
+
+	CONFIG_SCIn_SERIAL_CONSOLE - selects SCIn for the console and ttys0
+	  (default is the SCI0).
+
+	CONFIG_SCIn_RXBUFSIZE - Characters are buffered as received.
+	   This specific the size of the receive buffer
+
+	CONFIG_SCIn_TXBUFSIZE - Characters are buffered before
+	   being sent.  This specific the size of the transmit buffer
+
+	CONFIG_SCIn_BAUD - The configure BAUD of the UART.
+
+	CONFIG_SCIn_BITS - The number of bits.  Must be either 7 or 8.
+
+	CONFIG_SCIn_PARTIY - 0=no parity, 1=odd parity, 2=even parity, 3=mark 1, 4=space 0
+
+	CONFIG_SCIn_2STOP - Two stop bits

+can be selected as follow:
+
+	cd tools
+	./configure.sh demo9s12nec64/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+ostest:
+  This configuration directory, performs a simple OS test using
+  examples/ostest.

+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. Raisonance GNU toolchain, or
+  4. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery, devkitARM or Raisonance GNU toolchain, you simply need to
+  add one of the following configuration options to your .config (or defconfig)
+  file:
+
+    CONFIG_LPC31_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_LPC31_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_LPC31_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_LPC31_BUILDROOT=y	    : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_LPC31_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows), devkitARM, and Raisonance toolchains are
+  Windows native toolchains.  The CodeSourcey (for Linux) and NuttX buildroot
+  toolchains are Cygwin and/or Linux native toolchains. There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+^^^^
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project (There is a simple RIDE project
+  in the RIDE subdirectory).
+
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/lpc31xx,
+     arch/arm/src/common, arch/arm/src/arm, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/lpc31xx/lpc31_vectors.S.  With RIDE, I have to build NuttX
+  one time from the Cygwin command line in order to obtain the pre-built
+  startup object needed by RIDE.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh ea3131/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/arm926t-defconfig-4.2.4 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you are
+  building a Cortex-M3 toolchain for Cygwin under Windows.
+
+Boot Sequence
+^^^^^^^^^^^^^
+  LPC313x has on chip bootrom which loads properly formatted images from multiple
+  sources into SRAM.  These sources include including SPI Flash, NOR Flash, UART,
+  USB, SD Card, and NAND Flash.
+
+  In all configurations, NuttX is loaded directly into ISRAM.  NuttX is linked
+  to execute from ISRAM, regardless of the boot source.
+
+Image Format
+^^^^^^^^^^^^
+
+  In order to use the bootrom bootloader, a special header must be added to the
+  beginning of the binary image that includes information about the binary (things
+  like the entry point, the size, and CRC's to verify the image.
+
+  NXP provides a Windows program to append such a header to the binary image.
+  However, (1) that program won't run under Linux, and (2) when I try it under
+  WinXP, Symantec immediately claims that the program is misbehaving and deletes
+  it!
+
+  To work around both of these issues, I have created a small program under
+  configs/ea3131/tools to add the header.  This program can be built under
+  either Linux or Cygwin (and probably other tool environments as well).  That
+  tool can be built as follows:
+
+  - cd configs/ea3131/tools
+  - make
+
+  Then, to build the NuttX binary ready to load with the bootloader, just
+  following these steps:
+
+  - cd tools/				# Configure Nuttx
+  - ./configure.sh ea3131/ostest	# (using the ostest configuration for this example)
+  - cd ..				# Set up environment
+  - . ./setenv.sh			# (see notes below)
+  - make				# Make NuttX.  This will produce nuttx.bin
+  - mklpc.sh				# Make the bootloader binary (nuttx.lpc)
+
+  NOTES:
+  
+    1. setenv.sh just sets up pathes to the toolchain and also to
+       configs/ea3131/tools where mklpc.sh resides. Use of setenv.sh is optional.
+       If you don't use setenv.sh, then just set your PATH variable appropriately or
+       use the full path to mklpc.sh in the final step.
+    2. You can instruct Symantec to ignore the errors and it will stop quarantining
+       the NXP program.
+    3. The CRC32 logic in configs/ea3131/tools doesn't seem to work.  As a result,
+       the CRC is currently disabled in the header:
+
+       RCS file: /cvsroot/nuttx/nuttx/configs/ea3131/tools/lpchdr.c,v
+       retrieving revision 1.2
+       diff -r1.2 lpchdr.c
+       264c264
+       <   g_hdr.imageType       = 0x0000000b;
+       ---
+       >   g_hdr.imageType       = 0x0000000a;
+
+Image Download to ISRAM
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Assuming that you already have the FTDI driver installed*, then here is the
+are the steps that I use for loading new code into the EA3131:
+
+- Create the bootloader binary, nuttx.lpc, as described above.
+- Connected the EA3131 using the FTDI USB port (not the lpc3131 USB port)
+  This will power up the EA3131 and start the bootloader.
+- Start a terminal emulator (such as TeraTerm) at 115200 8NI.
+- Reset the EA3131 and you should see:
+  LPC31xx READY FOR PLAIN IMAGE>
+- Send the nuttx.lpc file and you should see:
+  Download finished
+
+That will load the NuttX binary into ISRAM and attempt to execute it.
+
+*See the LPC313x documentation if you do not have the FTDI driver installed.
+
+Using OpenOCD and GDB
+^^^^^^^^^^^^^^^^^^^^^
+
+  I have been using the Olimex ARM-USB-OCD JTAG debugger with the EA3131
+  (http://www.olimex.com).  The OpenOCD configuration file is here:
+  tools/armusbocb.cfg.  There is also a script on the tools directory that
+  I used to start the OpenOCD daemon on my system called oocd.sh.  That
+  script would probably require some modifications to work in another
+  environment:
+  
+    - possibly the value of OPENOCD_PATH
+    - If you are working under Linux you will need to change any
+      occurances of `cygpath -w blablabla` to just blablabla
+
+  Then you should be able to start the OpenOCD daemon like:
+
+    configs/ea3131/tools/oocd.sh $PWD
+
+  Where it is assumed that you are executing oocd.sh from the top level
+  directory where NuttX is installed.
+
+  Once the OpenOCD daemon has been started, you can connect to it via
+  GDB using the following GDB command:
+
+   arm-elf-gdb
+   (gdb) target remote localhost:3333
+
+  And you can load the NuttX ELF file:
+
+   (gdb) symbol-file nuttx
+   (gdb) load nuttx
+
+On-Demand Paging
+^^^^^^^^^^^^^^^^
+
+  There is a configuration that was used to verify the On-Demand Paging
+  feature for the ARM926 (see http://nuttx.sourceforge.net/NuttXDemandPaging.html).
+  That configuration is contained in the pgnsh sub-directory.  The pgnsh configuration
+  is only a test configuration, and lacks some logic to provide the full On-Demand
+  Paging solution (see below).
+
+  Page Table Layout:
+  ------------------
+
+  The ARM926 MMU uses a page table in memory.  The page table is divided
+  into (1) a level 1 (L1) page table that maps 1Mb memory regions to level 2
+  page tables (except in the case of 1Mb sections, of course), and (2) a level
+  2 (L2) page table that maps the 1Mb memory regions into individual 64Kb, 4kb,
+  or 1kb pages.  The pgnsh configuration uses 1Kb pages:  it positions 48x1Kb
+  pages at beginning of SRAM (the "locked" memory region), 16x1Kb pages at
+  the end of SRAM for the L1 page table, and 44x1Kb pages just before the
+  L1 page table.  That leaves 96x1Kb virtual pages in the middle of SRAM for
+  the paged memory region; up to 384x1kb of physical pages may be paged into
+  this region.  Physical memory map:
+  
+    11028000 "locked" text region   48x1Kb
+    11034000 "paged" text region    96x1Kb
+    1104c000 "data" region          32x1Kb
+    11054000 L1 page table          16x1Kb
+    -------- --------------------- ------
+    11058000                       192x1Kb
+
+  The virtual memory map allows more space for the paged region:
+
+    11028000 "locked" text region   48x1Kb
+    11034000 "paged" text region   384x1Kb
+    11094000 "data" region          32x1Kb
+    1109c000 L1 page table          16x1Kb
+    -------- --------------------- ------
+    110a0000                       480x1Kb
+
+  The L1 contains a single 1Mb entry to span the entire LPC3131 SRAM memory
+  region.  The virtual address for this region is 0x11028000.  The offset into
+  the L1 page table is given by:
+  
+    offset = ((0x11028000 >> 20) << 2) = 0x00000440
+
+  The value at that offset into the L1 page table contains the address of the
+  L2 page table (0x11056000) plus some extra bits to specify that that entry
+  is valid and and points to a 1Kb L1 page table:
+  
+    11054440 11056013
+
+  Why is the address 11056000 used for the address of the L2 page table?  Isn't
+  that inside of the L1 page table?  Yes, this was done to use the preceious
+  SRAM memory more conservatively.  If you look at the LPC313x virtual memory
+  map, you can see that no virtual addresses above 0x60100000 are used.  That
+  corresponds to L1 page table offset 0x0001800 (physical address 0x11055800).
+  The rest of the L1 page table is unused and so we reuse it to hold the L2 page
+  table (or course, this could cause some really weird addressing L1 mapping
+  issues if bad virtual addresses were used in that region -- oh well).  The
+  address 0x11056000 is then the first properly aligned memory that can be used
+  in that L2 page table area.
+
+  Only only L2 page table will be used to span the LPC3131 SRAM virtual text
+  address region (480x1Kb).  That one entry maps the virtual address range of
+  0x11000000 through 0x110ffc00.  Each entry maps a 1Kb page of physical memory:
+  
+    PAGE      VIRTUAL ADDR L2 OFFSET
+    --------- ------------ ---------
+    Page 0    0x11000000   0x00000000
+    Page 1    0x11000400   0x00000004
+    Page 2    0x11000800   0x00000008
+    ...
+    Page 1023 0x110ffc00   0x00000ffc
+  
+  The "locked" text region begins at an offset of 0x00028000 into that region.
+  The 48 page table entries needed to make this region begin at:
+  
+    offset = ((0x00028000 >> 10) << 2) = 0x00000280
+
+  Each entry contains the address of a physical page in the "locked" text region
+  (plus some extra bits to identify domains, page sizes, access privileges, etc.):
+
+    0x11000280 0x1102800b
+    0x11000284 0x1102840b
+    0x11000288 0x1102880b
+    ...
+
+  The locked region is initially unmapped.  But the data region and page table
+  regions must be mapped in a similar manner.  Those 
+  
+    Data:
+       Virtual address  = 0x11094000 Offset = 0x00064000
+       Physical address = 0x1104c000
+       L2 offset        = ((0x00094000 >> 10) << 2) = 0x00000940
+
+    Page table:
+       Virtual address  = 0x1109c000 Offset = 0x0009c000
+       Physical address = 0x11054000
+       L2 offset        = ((0x0009c000 >> 10) << 2) = 0x000009c0
+
+  Build Sequence:
+  ---------------
+
+  This example uses a two-pass build.  The top-level Makefile recognizes the
+  configuration option CONFIG_BUILD_2PASS and will execute the Makefile in
+  configs/ea3131/locked/Makefile to build the first pass object, locked.r.
+  This first pass object contains all of the code that must be in the locked
+  text region. The Makefile in arch/arm/src/Makefile then includes this 1st
+  pass in build, positioning it as controlled by configs/ea3131/scripts/pg-ld.script.
+
+  Finishing the Example:
+  ----------------------
+
+  This example is incomplete in that it does not have any media to reload the
+  page text region from:  The file configs/ea3131/src/up_fillpage.c is only
+  a stub.  That logic to actually reload the page from some storage medium
+  (among other things) would have to be implemented in order to complete this
+  example.  At present, the example works correctly up to the point where
+  up_fillpage() is first called and then fails in the expected way.
+
+  Here are the detailed list of things that would need to be done in addition
+  to finishing th up_fillpage() logic (this assumes that SPI NOR FLASH is the
+  media on which the NuttX image is stored):
+
+  1. Develop a NOR FLASH layout can can be used to (1) boot the locked text
+     section into memory on a reset, and (2) map a virtual fault address
+     to an offset into paged text section in NOR FLASH.
+  2. Develop/modify the build logic to build the binaries for this NOR
+     flash layout: Can the NuttX image be formed as a single image that
+     is larger than the IRAM?  Can we boot from such a large image?  If
+     so, then no special build modifications are required.  Or, does the
+     locked section have to be smaller with a separate paged text section
+     image in FLASH?  In this case, some tool will be needed to break
+     the nuttx.bin file into the two pieces.
+  3. Develop a mechanism to load the NuttX image into SPI NOR FLASH.  A
+     basic procedure is already documented in NXP publications: "LPC313x
+     Linux Quick Start Guide, Version 2.0" and "AN10811 Programming SPI
+     flash on EA3131 boards, V1 (May 1, 2009)."  That procedure may be
+     sufficient, depending on the decisions made in (1) and (2):  
+  4. Develop a procedure to boot the locked text image from SPI NOR.
+     The references and issues related to this are discussed in (2)
+     and (3) above.
+
+  Basic support for paging from SPI NOR FLASH can be enabled by adding:
+
+    CONFIG_PAGING_AT45DB=y
+
+  Or:
+
+    CONFIG_PAGING_M25PX=y
+
+  NOTE:  See the TODO list in the top-level directory:
+  
+    "arch/arm/src/lpc31xx/lpc31_spi.c may or may not be functional.  It was
+     reported to be working, but I was unable to get it working with the
+     Atmel at45dbxx serial FLASH driver."
+
+  Alternative:
+  ------------
+
+  I have implemented an alternative within configs/ea3131/src/up_fillpage.c
+  which is probably only useful for testing.  Here is the usage module
+  for this alternative
+
+  1. Place the nuttx.bin file on an SD card.
+  2. Insert the SD card prior to booting
+  3. In up_fillpage(), use the virtual miss address (minus the virtual
+     base address) as an offset into the nuttx.bin file, and read the
+     required page from that offset in the nuttx.bin file:
+
+     off_t offset = (off_t)vpage - PG_LOCKED_VBASE;
+     off_t pos    = lseek(fd, offset, SEEK_SET);
+     if (pos != (off_t)-1)
+       {
+         int ret = read(fd, vpage, PAGESIZE);
+       }
+
+  In this way, the paging implementation can do on-demand paging
+  from an image file on the SD card.  Problems/issues with this
+  approach probably make it only useful for testing:
+
+  1. You would still have to boot the locked section over serial or
+     using a bootloader -- it is not clear how the power up boot
+     would occur.  For testing, the nuttx.bin file could be both
+     provided on the SD card and loaded over serial. 
+  2. If the SD card is not in place, the system will crash.
+  3. This means that all of the file system logic and FAT file
+     system would have to reside in the locked text region.
+
+  And the show-stopper:
+
+  4. There is no MCI driver for the ea3131, yet!
+
+ARM/EA3131-specific Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+	   be set to:
+
+	   CONFIG_ARCH=arm
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_ARM=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_ARM926EJS=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=lpc313x
+
+	CONFIG_ARCH_CHIP_name - For use in C code
+
+	   CONFIG_ARCH_CHIP_LPC3131
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=ea3131
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_EA3131
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - For most ARM9 architectures, this describes the
+	  size of installed DRAM.  For the LPC313X, it is used only to
+	  deterimine how to map the executable regions.  It is SDRAM size
+	  only if you are executing out of the external SDRAM; or it could
+	  be NOR FLASH size, external SRAM size, or internal SRAM size.
+
+	CONFIG_DRAM_START - The start address of installed DRAM (physical)
+
+	CONFIG_DRAM_VSTART - The startaddress of DRAM (virtual)
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_IRQPRIO - The LPC313x supports interrupt prioritization
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	   stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_BOOTLOADER - Set if you are using a bootloader.
+
+	CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+	CONFIG_ARCH_BUTTONS -  Enable support for buttons. Unique to board architecture.
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.
+	CONFIG_ARCH_DMA - Support DMA initialization
+	CONFIG_ARCH_LOWVECTORS - define if vectors reside at address 0x0000:00000
+	  Undefine if vectors reside at address 0xffff:0000
+	CONFIG_ARCH_ROMPGTABLE - A pre-initialized, read-only page table is available.
+	  If defined, then board-specific logic must also define PGTABLE_BASE_PADDR,
+	  PGTABLE_BASE_VADDR, and all memory section mapping in a file named
+	  board_memorymap.h.
+
+  Individual subsystems can be enabled:
+
+	CONFIG_LPC31_MCI, CONFIG_LPC31_SPI, CONFIG_LPC31_UART
+
+  External memory available on the board (see also CONFIG_MM_REGIONS)
+
+	CONFIG_LPC31_EXTSRAM0 - Select if external SRAM0 is present
+	CONFIG_LPC31_EXTSRAM0HEAP - Select if external SRAM0 should be
+	  configured as part of the NuttX heap.
+	CONFIG_LPC31_EXTSRAM0SIZE - Size (in bytes) of the installed
+	  external SRAM0 memory
+	CONFIG_LPC31_EXTSRAM1 - Select if external SRAM1 is present
+	CONFIG_LPC31_EXTSRAM1HEAP - Select if external SRAM1 should be
+	  configured as part of the NuttX heap.
+	CONFIG_LPC31_EXTSRAM1SIZE - Size (in bytes) of the installed
+	  external SRAM1 memory
+	CONFIG_LPC31_EXTSDRAM - Select if external SDRAM is present
+	CONFIG_LPC31_EXTSDRAMHEAP - Select if external SDRAM should be
+	  configured as part of the NuttX heap.
+	CONFIG_LPC31_EXTSDRAMSIZE - Size (in bytes) of the installed
+	  external SDRAM memory
+	CONFIG_LPC31_EXTNAND - Select if external NAND is present
+	CONFIG_LPC31_EXTSDRAMSIZE - Size (in bytes) of the installed
+	  external NAND memory
+
+  LPC313X specific device driver settings
+
+	CONFIG_UART_SERIAL_CONSOLE - selects the UART for the
+	  console and ttys0
+	CONFIG_UART_RXBUFSIZE - Characters are buffered as received.
+	  This specific the size of the receive buffer
+	CONFIG_UART_TXBUFSIZE - Characters are buffered before
+	  being sent.  This specific the size of the transmit buffer
+	CONFIG_UART_BAUD - The configure BAUD of the UART.  Must be
+	CONFIG_UART_BITS - The number of bits.  Must be either 7 or 8.
+	CONFIG_UART_PARTIY - 0=no parity, 1=odd parity, 2=even parity
+	CONFIG_UART_2STOP - Two stop bits
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each EA3131 configuration is maintained in a sudirectory and can be
+selected as follow:
+
+	cd tools
+	./configure.sh ea3131/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  locked
+    This is not a configuration.  When on-demand page is enabled
+    then we must do a two pass link:  The first pass creates an
+    intermediate object that has all of the code that must be
+    placed in the locked memory partition.  This is logic that
+    must be locked in memory at all times.
+
+    The directory contains the logic necessary to do the platform
+    specific first pass link for the EA313x.
+ 
+  nsh:
+    Configures the NuttShell (nsh) located at examples/nsh.  The
+    Configuration enables only the serial NSH interface.
+
+  ostest:
+    This configuration directory, performs a simple OS test using
+    examples/ostest.  By default, this project assumes that you are
+    using the DFU bootloader.
+
+  pgnsh:
+    This is the same configuration as nsh, but with On-Demand
+    paging enabled.  See http://www.nuttx.org/NuttXDemandPaging.html.
+    This configuration is an experiment for the purposes of test
+    and debug.  At present, this does not produce functioning, 
+    usable system
+ 
+  usbserial:
+    This configuration directory exercises the USB serial class
+    driver at examples/usbserial.  See examples/README.txt for
+    more information.
+
+  usbstorage:
+    This configuration directory exercises the USB mass storage
+    class driver at examples/usbstorage.  See examples/README.txt for
+    more information.

+ * Public Functions
+ ****************************************************************************/
+
+/****************************************************************************
+ * Name: up_fillpage()
+ *
+ * Description:
+ *  After a page is allocated and mapped by up_allocpage(), the actual
+ *  filling of the page with data from the non-volatile, must be performed
+ *  by a separate call to the architecture-specific function, up_fillpage().
+ *  This function is non-blocking, it will start an asynchronous page fill.
+ *  The common paging logic will provide a callback function, pg_callback,
+ *  that will be called when the page fill is finished (or an error occurs).
+ *  This callback is assumed to occur from an interrupt level when the
+ *  device driver completes the fill operation.
+ *
+ *  NOTE 1: Allocating and filling a page is a two step process.  up_allocpage()
+ *  allocates the page, and up_fillpage() fills it with data from some non-
+ *  volatile storage device.  This distinction is made because up_allocpage()
+ *  can probably be implemented in board-independent logic whereas up_fillpage()
+ *  probably must be implemented as board-specific logic.
+ *
+ *  NOTE 2: The initial mapping of vpage will be read-able, write-able,
+ *  but non-cacheable.  No special actions will be required of
+ *  up_fillpage() in order to write into this allocated page.  If the
+ *  virtual address maps to a text region, however, this function should
+ *  remap the region so that is is read/execute only.  It should be made
+ *  cache-able in any case.
+
+ * Input Parameters:
+ *   tcb - A reference to the task control block of the task that needs to
+ *         have a page fill.  Architecture-specific logic can retrieve page
+ *         fault information from the architecture-specific context
+ *         information in this TCB to perform the fill.
+ *   pg_callbck - The function to be called when the page fill is complete.
+ *
+ * Returned Value:
+ *   This function will return zero (OK) if the page fill was successfully
+ *   started (the result of the page fill is passed to the callback function
+ *   as the result argument).  A negated errno value may be returned if an
+ *   error occurs.  All errors, however, are fatal.
+ *
+ *   NOTE: -EBUSY has a special meaning. It is used internally to mean that
+ *   the callback function has not executed.  Therefore, -EBUSY should
+ *   never be provided in the result argument of pg_callback.
+ *
+ * Assumptions:
+ *   - This function is called from the normal tasking context (but
+ *     interrupts siabled).  The implementation must take whatever actions
+ *     are necessary to assure that the operation is safe within this context.
+ *   - Upon return, the caller will sleep waiting for the page fill callback
+ *     to occur.  The callback function will perform the wakeup.

+ * Description:
+ *   Configure SDRAM on the EA3131 board
+ *
+ * Micron Initialization Sequence from their data sheet for the Micron
+ * MT48LC32M16A2 32M x 16 SDRAM chip:
+ *   
+ *   "SDRAMs must be powered up and initialized in a predefined manner.
+ *    Operational procedures other than those specified may result in
+ *    undefined operation. Once power is applied to VDD and VDDQ
+ *    (simultaneously) and the clock is stable (stable clock is defined as
+ *    a signal cycling within timing constraints specified for the clock
+ *    pin), the SDRAM requires a 100µs delay prior to issuing any command
+ *    other than a COMMAND INHIBIT or NOP.
+ *   
+ *   "Starting at some point during this 100µs period and continuing at least
+ *    through the end of this period, COMMAND INHIBIT or NOP commands should
+ *    be applied.  Once the 100µs delay has been satisfied with at least one
+ *    COMMAND INHIBIT or NOP command having been applied, a PRECHARGE command
+ *    should be applied. All banks must then be precharged, thereby placing
+ *    the device in the all banks idle state.
+ *   
+ *   "Once in the idle state, two AUTO REFRESH cycles must be performed. After
+ *    the AUTO REFRESH cycles are complete, the SDRAM is ready for mode
+ *    register programming.
+ *   
+ *   "Because the mode register will power up in an unknown state, it should
+ *    be loaded prior to applying any operational command."
+ *
+ *  The JEDEC recommendation for initializing SDRAM is:
+ *    
+ *    APPLY POWER (Vdd/Vddq equally, and CLK is stable)
+ *    Wait 200uS
+ *    PRECHARGE all
+ *    8 AUTO REFRESH COMMANDS
+ *    LOAD MODE REGISTER
+ *    SDRAM is ready for operation
+ *    
+ *  The Micron SDRAM parts will work fine with the JEDEC sequence, but also
+ *  allow for a quicker init sequence of:
+ *    
+ *    APPLY POWER (Vdd/Vddq equally, and CLK is stable)
+ *    Wait at least 100uS (during which time start applying and
+ *       continue applying NOP or COMMAND INHIBIT)
+ *    PRECHARGE all
+ *    2 AUTO REFRESH COMMANDS (min requirement, more than 2 is also ok)
+ *    LOAD MODE REGISTER
+ *    SDRAM is ready for operation

+ *   2. Provide lpc31_spiselect() and lpc31_spistatus() functions in your
+ *      board-specific logic.  These functions will perform chip selection and
+ *      status operations using GPIOs in the way your board is configured.
+ *   3. Add a calls to up_spiinitialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by up_spiinitialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling

+ *
+ * This file is a part of NuttX:
+ *
+ *   Copyright (C) 2010 Gregory Nutt. All rights reserved.
+ *
+ * The logic in this file was developed by Gary S. Brown:
+ *
+ *   COPYRIGHT (C) 1986 Gary S. Brown.  You may use this program, or code or tables
+ *   extracted from it, as desired without restriction.
+ *
+ * First, the polynomial itself and its table of feedback terms.  The polynomial is:
+ *
+ *    X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
+ *
+ * Note that we take it "backwards" and put the highest-order term in the lowest-order bit.
+ * The X^32 term is "implied"; the LSB is the X^31 term, etc.  The X^0 term (usually shown
+ * as "+1") results in the MSB being 1
+ *
+ * Note that the usual hardware shift register implementation, which is what we're using
+ * (we're merely optimizing it by doing eight-bit chunks at a time) shifts bits into the
+ * lowest-order term.  In our implementation, that means shifting towards the right.  Why
+ * do we do it this way?  Because the calculated CRC must be transmitted in order from
+ * highest-order term to lowest-order term.  UARTs transmit characters in order from LSB
+ * to MSB.  By storing the CRC this way we hand it to the UART in the order low-byte to
+ * high-byte; the UART sends each low-bit to hight-bit; and the result is transmission bit
+ * by bit from highest- to lowest-order term without requiring any bit shuffling on our
+ * part.  Reception works similarly
+ *
+ * The feedback terms table consists of 256, 32-bit entries.  Notes
+ *
+ * - The table can be generated at runtime if desired; code to do so is shown later.  It
+ *   might not be obvious, but the feedback terms simply represent the results of eight
+ *   shift/xor operations for all combinations of data and CRC register values
+ *
+ * - The values must be right-shifted by eight bits by the updcrc logic; the shift must
+ *   be u_(bring in zeroes).  On some hardware you could probably optimize the shift in
+ *   assembler by using byte-swap instructions polynomial $edb88320

+Repair procedure for ARM-USB-OCD drivers
+
+1.   Uninstalling ARM-USB-OCD drivers
+-------------------------------------
+1.1. Connect your programmer/debugger to your computer, open Device Manager
+     and uninstall the drivers for ARM-USB-OCD.
+1.2. After you have uninstalled ARM-USB-TINY driver from Device Manager,
+     disconnect the programmer from your computer.
+1.3. Now you should download FTClean.exe from here:
+     http://www.ftdichip.com/Support/Utilities/FTClean.zip.
+1.4. After download is complete extract the "*.zip" file, open folder FTClean,
+     and run FTClean.exe
+1.5. Ror VID (Hex) select "Other". And after that fill the first box with 15ba
+     and "PID (Hex)" with 0004.
+1.6. Press "Clean System" button.  Make sure that all FTDI devices are
+     disconnected. (My require administrator privileges).
+
+2. Re-installing the ARM-USB-OCD driver
+---------------------------------------
+2.1 Connect the programmer/debugger to the computer.
+2.2 When prompted, browse to the C:\gccfd\DRIVERS\ARM-USB-OCD-DRIVER
+    directory and install. (A different driver is required for OpenOCD
+    0.4.0.  That driver is available from the olimex.com web site).

+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. Raisonance GNU toolchain, or
+  4. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery, devkitARM or Raisonance GNU toolchain, you simply need to
+  add one of the following configuration options to your .config (or defconfig)
+  file:
+
+    CONFIG_LPC31_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_LPC31_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_LPC31_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_LPC31_BUILDROOT=y	    : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_LPC31_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows), devkitARM, and Raisonance toolchains are
+  Windows native toolchains.  The CodeSourcey (for Linux) and NuttX buildroot
+  toolchains are Cygwin and/or Linux native toolchains. There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+^^^^
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project (There is a simple RIDE project
+  in the RIDE subdirectory).
+
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/lpc31xx,
+     arch/arm/src/common, arch/arm/src/arm, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/lpc31xx/lpc31_vectors.S.  With RIDE, I have to build NuttX
+  one time from the Cygwin command line in order to obtain the pre-built
+  startup object needed by RIDE.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh ea3152/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/arm926t-defconfig-4.2.4 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you are
+  building a Cortex-M3 toolchain for Cygwin under Windows.
+
+Boot Sequence
+^^^^^^^^^^^^^
+  LPC313x has on chip bootrom which loads properly formatted images from multiple
+  sources into SRAM.  These sources include including SPI Flash, NOR Flash, UART,
+  USB, SD Card, and NAND Flash.
+
+  In all configurations, NuttX is loaded directly into ISRAM.  NuttX is linked
+  to execute from ISRAM, regardless of the boot source.
+
+Image Format
+^^^^^^^^^^^^
+
+  In order to use the bootrom bootloader, a special header must be added to the
+  beginning of the binary image that includes information about the binary (things
+  like the entry point, the size, and CRC's to verify the image.
+
+  NXP provides a Windows program to append such a header to the binary image.
+  However, (1) that program won't run under Linux, and (2) when I try it under
+  WinXP, Symantec immediately claims that the program is misbehaving and deletes
+  it!
+
+  To work around both of these issues, I have created a small program under
+  configs/ea3152/tools to add the header.  This program can be built under
+  either Linux or Cygwin (and probably other tool environments as well).  That
+  tool can be built as follows:
+
+  - cd configs/ea3152/tools
+  - make
+
+  Then, to build the NuttX binary ready to load with the bootloader, just
+  following these steps:
+
+  - cd tools/				# Configure Nuttx
+  - ./configure.sh ea3152/ostest	# (using the ostest configuration for this example)
+  - cd ..				# Set up environment
+  - . ./setenv.sh			# (see notes below)
+  - make				# Make NuttX.  This will produce nuttx.bin
+  - mklpc.sh				# Make the bootloader binary (nuttx.lpc)
+
+  NOTES:
+  
+    1. setenv.sh just sets up pathes to the toolchain and also to
+       configs/ea3152/tools where mklpc.sh resides. Use of setenv.sh is optional.
+       If you don't use setenv.sh, then just set your PATH variable appropriately or
+       use the full path to mklpc.sh in the final step.
+    2. You can instruct Symantec to ignore the errors and it will stop quarantining
+       the NXP program.
+    3. The CRC32 logic in configs/ea3152/tools doesn't seem to work.  As a result,
+       the CRC is currently disabled in the header:
+
+       RCS file: /cvsroot/nuttx/nuttx/configs/ea3152/tools/lpchdr.c,v
+       retrieving revision 1.2
+       diff -r1.2 lpchdr.c
+       264c264
+       <   g_hdr.imageType       = 0x0000000b;
+       ---
+       >   g_hdr.imageType       = 0x0000000a;
+
+Image Download to ISRAM
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Assuming that you already have the FTDI driver installed*, then here is the
+are the steps that I use for loading new code into the EA3152:
+
+- Create the bootloader binary, nuttx.lpc, as described above.
+- Connected the EA3152 using the FTDI USB port (not the lpc3152 USB port)
+  This will power up the EA3152 and start the bootloader.
+- Start a terminal emulator (such as TeraTerm) at 115200 8NI.
+- Reset the EA3152 and you should see:
+  LPC31xx READY FOR PLAIN IMAGE>
+- Send the nuttx.lpc file and you should see:
+  Download finished
+
+That will load the NuttX binary into ISRAM and attempt to execute it.
+
+*See the LPC313x documentation if you do not have the FTDI driver installed.
+
+Using OpenOCD and GDB
+^^^^^^^^^^^^^^^^^^^^^
+
+  I have been using the Olimex ARM-USB-OCD JTAG debugger with the EA3152
+  (http://www.olimex.com).  The OpenOCD configuration file is here:
+  tools/armusbocb.cfg.  There is also a script on the tools directory that
+  I used to start the OpenOCD daemon on my system called oocd.sh.  That
+  script would probably require some modifications to work in another
+  environment:
+  
+    - possibly the value of OPENOCD_PATH
+    - If you are working under Linux you will need to change any
+      occurances of `cygpath -w blablabla` to just blablabla
+
+  Then you should be able to start the OpenOCD daemon like:
+
+    configs/ea3152/tools/oocd.sh $PWD
+
+  Where it is assumed that you are executing oocd.sh from the top level
+  directory where NuttX is installed.
+
+  Once the OpenOCD daemon has been started, you can connect to it via
+  GDB using the following GDB command:
+
+   arm-elf-gdb
+   (gdb) target remote localhost:3333
+
+  And you can load the NuttX ELF file:
+
+   (gdb) symbol-file nuttx
+   (gdb) load nuttx
+
+ARM/EA3152-specific Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+	   be set to:
+
+	   CONFIG_ARCH=arm
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_ARM=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_ARM926EJS=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=lpc313x
+
+	CONFIG_ARCH_CHIP_name - For use in C code
+
+	   CONFIG_ARCH_CHIP_LPC3152
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=ea3152
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_EA3152
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - For most ARM9 architectures, this describes the
+	  size of installed DRAM.  For the LPC313X, it is used only to
+	  deterimine how to map the executable regions.  It is SDRAM size
+	  only if you are executing out of the external SDRAM; or it could
+	  be NOR FLASH size, external SRAM size, or internal SRAM size.
+
+	CONFIG_DRAM_START - The start address of installed DRAM (physical)
+
+	CONFIG_DRAM_VSTART - The startaddress of DRAM (virtual)
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_IRQPRIO - The LPC313x supports interrupt prioritization
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	   stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_BOOTLOADER - Set if you are using a bootloader.
+
+	CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+	CONFIG_ARCH_BUTTONS -  Enable support for buttons. Unique to board architecture.
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.
+	CONFIG_ARCH_DMA - Support DMA initialization
+	CONFIG_ARCH_LOWVECTORS - define if vectors reside at address 0x0000:00000
+	  Undefine if vectors reside at address 0xffff:0000
+	CONFIG_ARCH_ROMPGTABLE - A pre-initialized, read-only page table is available.
+	  If defined, then board-specific logic must also define PGTABLE_BASE_PADDR,
+	  PGTABLE_BASE_VADDR, and all memory section mapping in a file named
+	  board_memorymap.h.
+
+  Individual subsystems can be enabled:
+
+	CONFIG_LPC31_MCI, CONFIG_LPC31_SPI, CONFIG_LPC31_UART
+
+  External memory available on the board (see also CONFIG_MM_REGIONS)
+
+	CONFIG_LPC31_EXTSRAM0 - Select if external SRAM0 is present

+	  external SRAM1 memory
+	CONFIG_LPC31_EXTSDRAM - Select if external SDRAM is present
+	CONFIG_LPC31_EXTSDRAMHEAP - Select if external SDRAM should be
+	  configured as part of the NuttX heap.
+	CONFIG_LPC31_EXTSDRAMSIZE - Size (in bytes) of the installed
+	  external SDRAM memory
+	CONFIG_LPC31_EXTNAND - Select if external NAND is present
+	CONFIG_LPC31_EXTSDRAMSIZE - Size (in bytes) of the installed

+
+Configurations
+^^^^^^^^^^^^^^
+
+Each EA3152 configuration is maintained in a sudirectory and can be
+selected as follow:
+
+	cd tools
+	./configure.sh ea3152/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  ostest:
+    This configuration directory, performs a simple OS test using
+    examples/ostest.  By default, this project assumes that you are
+    using the DFU bootloader.

+/****************************************************************************
+ * Name: up_fillpage()
+ *
+ * Description:
+ *  After a page is allocated and mapped by up_allocpage(), the actual
+ *  filling of the page with data from the non-volatile, must be performed
+ *  by a separate call to the architecture-specific function, up_fillpage().
+ *  This function is non-blocking, it will start an asynchronous page fill.
+ *  The common paging logic will provide a callback function, pg_callback,
+ *  that will be called when the page fill is finished (or an error occurs).
+ *  This callback is assumed to occur from an interrupt level when the
+ *  device driver completes the fill operation.
+ *
+ *  NOTE 1: Allocating and filling a page is a two step process.  up_allocpage()
+ *  allocates the page, and up_fillpage() fills it with data from some non-
+ *  volatile storage device.  This distinction is made because up_allocpage()
+ *  can probably be implemented in board-independent logic whereas up_fillpage()
+ *  probably must be implemented as board-specific logic.
+ *
+ *  NOTE 2: The initial mapping of vpage will be read-able, write-able,
+ *  but non-cacheable.  No special actions will be required of
+ *  up_fillpage() in order to write into this allocated page.  If the
+ *  virtual address maps to a text region, however, this function should
+ *  remap the region so that is is read/execute only.  It should be made
+ *  cache-able in any case.
+
+ * Input Parameters:
+ *   tcb - A reference to the task control block of the task that needs to
+ *         have a page fill.  Architecture-specific logic can retrieve page
+ *         fault information from the architecture-specific context
+ *         information in this TCB to perform the fill.
+ *   pg_callbck - The function to be called when the page fill is complete.
+ *
+ * Returned Value:
+ *   This function will return zero (OK) if the page fill was successfully
+ *   started (the result of the page fill is passed to the callback function
+ *   as the result argument).  A negated errno value may be returned if an
+ *   error occurs.  All errors, however, are fatal.
+ *
+ *   NOTE: -EBUSY has a special meaning. It is used internally to mean that
+ *   the callback function has not executed.  Therefore, -EBUSY should
+ *   never be provided in the result argument of pg_callback.
+ *
+ * Assumptions:
+ *   - This function is called from the normal tasking context (but
+ *     interrupts siabled).  The implementation must take whatever actions
+ *     are necessary to assure that the operation is safe within this context.
+ *   - Upon return, the caller will sleep waiting for the page fill callback
+ *     to occur.  The callback function will perform the wakeup.

+ * Micron Initialization Sequence from their data sheet for the Micron
+ * MT48LC32M16A2 32M x 16 SDRAM chip:
+ *   
+ *   "SDRAMs must be powered up and initialized in a predefined manner.
+ *    Operational procedures other than those specified may result in
+ *    undefined operation. Once power is applied to VDD and VDDQ
+ *    (simultaneously) and the clock is stable (stable clock is defined as
+ *    a signal cycling within timing constraints specified for the clock
+ *    pin), the SDRAM requires a 100µs delay prior to issuing any command
+ *    other than a COMMAND INHIBIT or NOP.
+ *   
+ *   "Starting at some point during this 100µs period and continuing at least
+ *    through the end of this period, COMMAND INHIBIT or NOP commands should
+ *    be applied.  Once the 100µs delay has been satisfied with at least one
+ *    COMMAND INHIBIT or NOP command having been applied, a PRECHARGE command
+ *    should be applied. All banks must then be precharged, thereby placing
+ *    the device in the all banks idle state.
+ *   
+ *   "Once in the idle state, two AUTO REFRESH cycles must be performed. After
+ *    the AUTO REFRESH cycles are complete, the SDRAM is ready for mode
+ *    register programming.
+ *   
+ *   "Because the mode register will power up in an unknown state, it should
+ *    be loaded prior to applying any operational command."
+ *
+ *  The JEDEC recommendation for initializing SDRAM is:
+ *    
+ *    APPLY POWER (Vdd/Vddq equally, and CLK is stable)
+ *    Wait 200uS
+ *    PRECHARGE all
+ *    8 AUTO REFRESH COMMANDS
+ *    LOAD MODE REGISTER
+ *    SDRAM is ready for operation
+ *    
+ *  The Micron SDRAM parts will work fine with the JEDEC sequence, but also
+ *  allow for a quicker init sequence of:
+ *    
+ *    APPLY POWER (Vdd/Vddq equally, and CLK is stable)
+ *    Wait at least 100uS (during which time start applying and
+ *       continue applying NOP or COMMAND INHIBIT)
+ *    PRECHARGE all
+ *    2 AUTO REFRESH COMMANDS (min requirement, more than 2 is also ok)
+ *    LOAD MODE REGISTER
+ *    SDRAM is ready for operation

+ *
+ * This file is a part of NuttX:
+ *
+ *   Copyright (C) 2011 Gregory Nutt. All rights reserved.
+ *
+ * The logic in this file was developed by Gary S. Brown:
+ *
+ *   COPYRIGHT (C) 1986 Gary S. Brown.  You may use this program, or code or tables
+ *   extracted from it, as desired without restriction.
+ *
+ * First, the polynomial itself and its table of feedback terms.  The polynomial is:
+ *
+ *    X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0
+ *
+ * Note that we take it "backwards" and put the highest-order term in the lowest-order bit.
+ * The X^32 term is "implied"; the LSB is the X^31 term, etc.  The X^0 term (usually shown
+ * as "+1") results in the MSB being 1
+ *
+ * Note that the usual hardware shift register implementation, which is what we're using
+ * (we're merely optimizing it by doing eight-bit chunks at a time) shifts bits into the
+ * lowest-order term.  In our implementation, that means shifting towards the right.  Why
+ * do we do it this way?  Because the calculated CRC must be transmitted in order from
+ * highest-order term to lowest-order term.  UARTs transmit characters in order from LSB
+ * to MSB.  By storing the CRC this way we hand it to the UART in the order low-byte to
+ * high-byte; the UART sends each low-bit to hight-bit; and the result is transmission bit
+ * by bit from highest- to lowest-order term without requiring any bit shuffling on our
+ * part.  Reception works similarly
+ *
+ * The feedback terms table consists of 256, 32-bit entries.  Notes
+ *
+ * - The table can be generated at runtime if desired; code to do so is shown later.  It
+ *   might not be obvious, but the feedback terms simply represent the results of eight
+ *   shift/xor operations for all combinations of data and CRC register values
+ *
+ * - The values must be right-shifted by eight bits by the updcrc logic; the shift must
+ *   be u_(bring in zeroes).  On some hardware you could probably optimize the shift in
+ *   assembler by using byte-swap instructions polynomial $edb88320

+Repair procedure for ARM-USB-OCD drivers
+
+1.   Uninstalling ARM-USB-OCD drivers
+-------------------------------------
+1.1. Connect your programmer/debugger to your computer, open Device Manager
+     and uninstall the drivers for ARM-USB-OCD.
+1.2. After you have uninstalled ARM-USB-TINY driver from Device Manager,
+     disconnect the programmer from your computer.
+1.3. Now you should download FTClean.exe from here:
+     http://www.ftdichip.com/Support/Utilities/FTClean.zip.
+1.4. After download is complete extract the "*.zip" file, open folder FTClean,
+     and run FTClean.exe
+1.5. Ror VID (Hex) select "Other". And after that fill the first box with 15ba
+     and "PID (Hex)" with 0004.
+1.6. Press "Clean System" button.  Make sure that all FTDI devices are
+     disconnected. (My require administrator privileges).
+
+2. Re-installing the ARM-USB-OCD driver
+---------------------------------------
+2.1 Connect the programmer/debugger to the computer.
+2.2 When prompted, browse to the C:\gccfd\DRIVERS\ARM-USB-OCD-DRIVER
+    directory and install. (A different driver is required for OpenOCD
+    0.4.0.  That driver is available from the olimex.com web site).

+README
+^^^^^^
+
+README file for the Microment Eagle100 NuttX port.
+
+References:
+^^^^^^^^^^
+
+  Micromint: http://www.micromint.com/
+  Luminary:  http://www.luminarymicro.com/
+
+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment because the Luminary FLASH programming application was used for
+  writing to FLASH and this application works only under Windows.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain, or
+  3. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery or devkitARM GNU toolchain, you simply need to build the
+  system as follows:
+
+     make                         # Will build for the devkitARM toolchain
+     make CROSSDEV=arm-eabi-      # Will build for the devkitARM toolchain
+     make CROSSDEV=arm-none-eabi- # Will build for the CodeSourcery toolchain
+     make CROSSDEV=arm-elf-       # Will build for the NuttX buildroot toolchain
+
+  Of course, hard coding this CROSS_COMPILE value in Make.defs file will save
+  some repetitive typing.
+
+  NOTE: the CodeSourcery and devkitARM toolchains are Windows native toolchains.
+  The NuttX buildroot toolchain is a Cygwin toolchain.  There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context; make CROSSDEV=arm-none-eabi-
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the CodeSourcery toolchain.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.  It has been reported to me that the
+  devkitARM will require an lower optimization level of -O1.  Currently all of the
+  Make.def files have -O2 for devkitARM -- if you are using this toolchain, you may
+  need to review these settings.
+
+CodeSourcery on Linux
+^^^^^^^^^^^^^^^^^^^^^
+
+  If you select the CodeSourcery toolchain, the make system will assume that you
+  are running a Windows version of the toolchain.  If you are running under Linux,
+  the the make will probably fail.  The fix is to edit your Make.defs file and
+  use something like:
+
+    CROSSDEV = arm-none-eabi-
+    WINTOOL = n
+    MKDEP = $(TOPDIR)/tools/mkdeps.sh
+    ARCHCPUFLAGS = -mcpu=cortex-m3 -mthumb -mfloat-abi=soft
+    ARCHINCLUDES = -I. -isystem $(TOPDIR)/include
+    ARCHXXINCLUDES = -I. -isystem $(TOPDIR)/include -isystem $(TOPDIR)/include/cxx
+    ARCHSCRIPT = -T$(TOPDIR)/configs/$(CONFIG_ARCH_BOARD)/ostest/ld.script
+    MAXOPTIMIZATION = -O2
+
+  The values for TOPDIR is provided by the make system; the value for CONFIG_ARCH_BOARD
+  is provided in your defconfig file.  'ostest' refers to the ostest/ configuration;
+  this would be different for other configurations.
+
+  For an example of a CodeSourcery-under-Linux Make.defs file, see
+  configs/stm3210e-eval/nsh/Make.defs.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh eagle100/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you are
+  building a Cortex-M3 toolchain for Cygwin under Windows.
+
+Ethernet-Bootloader
+^^^^^^^^^^^^^^^^^^^
+
+  Here are some notes about using the Luminary Ethernet boot-loader built
+  into the Eagle-100 board.
+
+  Built-In Application:
+
+  - The board has no fixed IP address but uses DHCP to get an address.
+    I used a D-link router; I can use a web browser to surf to the D-link
+    web page to get the address assigned by 
+
+  - Then you can use this IP address in your browser to surf to the Eagle-100
+    board.  It presents several interesting pages -- the most important is
+    the page called "Firmware Update".  That page includes instructions on
+    how to download code to the Eagle-100.
+
+  - After you burn the first program, you lose this application.  Then you
+    will probably be better off connected directly to the Eagle-100 board
+    or through a switch (The router caused problems for me during downloads).
+
+  Using the Ethernet Bootloader:
+
+  - You will need the "LM Flash Programmer application".  You can get that
+    program from the Luminary web site.  There is a link on the LM3S6918 page.
+
+  - Is there any documentation for using the bootloader?  Yes and No:  There
+    is an application note covering the bootloader on the Luminary site, but
+    it is not very informative.  The Eagle100 User's Manual has the best
+    information.
+
+  - Are there any special things I have to do in my code, other than setting 
+    the origin to 0x0000:2000 (APP_START_ADDRESS)?  No.  The bootloader assumes
+    that you have a vector table at that address .  The bootloader does the
+    following each time it boots (after you have downloaded the first valid
+    application):
+
+    o The bootloader sets the vector table register to the APP_START_ADDRESS,
+    o It sets the stack pointer to the address at APP_START_ADDRESS, and then
+    o Jumps to the address at APP_START_ADDRESS+4.
+
+  - You can force the bootloader to skip starting the application and stay
+    in the update mode.  You will need to do this in order to download a new
+    application.  You force the update mode by holding the user button on the
+    Eagle-100 board while resetting the board.  The user button is GPIOA, pin 6
+    (call FORCED_UPDATE_PIN in the bootloader code).
+
+  - Note 1:  I had to remove my D-Link router from the configuration in order
+    to use the LM Flash Programmer (the Bootloader issues BOOTP requests to
+    communicate with the LM Flash Programmer, my router was responding to
+    these BOOTP requests and hosing the download).  It is safer to connect
+    via a switch or via an Ethernet switch.
+
+  - Note 2:  You don't need the router's DHCPD server in the download
+    configuration; the Luminary Flash Programmer has the capability of
+    temporarily assigning the IP address to the Eagle-100 via BOOTP.
+
+Eagle100-specific Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+	   be set to:
+
+	   CONFIG_ARCH=arm
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_ARM=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_CORTEXM3=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=lm3s
+
+	CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+	   chip:
+
+	   CONFIG_ARCH_CHIP_LM3S6918
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=eagle100 (for the MicroMint Eagle-100 development board)
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_EAGLE100
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - Describes the installed DRAM (SRAM in this case):
+
+	   CONFIG_DRAM_SIZE=0x00010000 (64Kb)
+
+	CONFIG_DRAM_START - The start address of installed DRAM
+
+	   CONFIG_DRAM_START=0x20000000
+
+	CONFIG_ARCH_IRQPRIO - The LM3S6918 supports interrupt prioritization
+
+	   CONFIG_ARCH_IRQPRIO=y
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	    stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_BOOTLOADER - Configure to use the MicroMint Eagle-100
+	   Ethernet bootloader.
+
+	CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.
+
+  There are configurations for disabling support for interrupts GPIO ports.
+  GPIOH and GPIOJ must be disabled because they do not exist on the LM3S6918.
+  Additional interrupt support can be disabled if desired to reduce memory
+  footprint.
+
+	CONFIG_LM3S_DISABLE_GPIOA_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOB_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOC_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOD_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOE_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOF_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOG_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOH_IRQS=y
+	CONFIG_LM3S_DISABLE_GPIOJ_IRQS=y
+ 
+  LM3S6818 specific device driver settings
+
+	CONFIG_UARTn_SERIAL_CONSOLE - selects the UARTn for the
+	   console and ttys0 (default is the UART0).
+	CONFIG_UARTn_RXBUFSIZE - Characters are buffered as received.
+	   This specific the size of the receive buffer
+	CONFIG_UARTn_TXBUFSIZE - Characters are buffered before
+	   being sent.  This specific the size of the transmit buffer
+	CONFIG_UARTn_BAUD - The configure BAUD of the UART.  Must be
+	CONFIG_UARTn_BITS - The number of bits.  Must be either 7 or 8.
+	CONFIG_UARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
+	CONFIG_UARTn_2STOP - Two stop bits
+
+	CONFIG_SSI0_DISABLE - Select to disable support for SSI0
+	CONFIG_SSI1_DISABLE - Select to disable support for SSI1
+	CONFIG_SSI_POLLWAIT - Select to disable interrupt driven SSI support.
+	  Poll-waiting is recommended if the interrupt rate would be to
+	  high in the interrupt driven case.
+	CONFIG_SSI_TXLIMIT - Write this many words to the Tx FIFO before
+	  emptying the Rx FIFO.  If the SPI frequency is high and this
+	  value is large, then larger values of this setting may cause
+	  Rx FIFO overrun errors.  Default: half of the Tx FIFO size (4).
+
+	CONFIG_LM3S_ETHERNET - This must be set (along with CONFIG_NET)
+	  to build the LM3S Ethernet driver
+	CONFIG_LM3S_ETHLEDS - Enable to use Ethernet LEDs on the board.
+	CONFIG_LM3S_BOARDMAC - If the board-specific logic can provide
+	  a MAC address (via lm3s_ethernetmac()), then this should be selected.
+	CONFIG_LM3S_ETHHDUPLEX - Set to force half duplex operation
+	CONFIG_LM3S_ETHNOAUTOCRC - Set to suppress auto-CRC generation
+	CONFIG_LM3S_ETHNOPAD - Set to suppress Tx padding
+	CONFIG_LM3S_MULTICAST - Set to enable multicast frames
+	CONFIG_LM3S_PROMISCUOUS - Set to enable promiscuous mode
+	CONFIG_LM3S_BADCRC - Set to enable bad CRC rejection.
+	CONFIG_LM3S_DUMPPACKET - Dump each packet received/sent to the console.
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each Eagle-100 configuration is maintained in a sudirectory and
+can be selected as follow:
+
+	cd tools
+	./configure.sh eagle100/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  nettest:
+    This configuration directory may be used to enable networking using the
+    LM3S6918's Ethernet controller. It uses examples/nettest to excercise the
+    TCP/IP network.
+
+  httpd:
+    This builds the uIP web server example using the examples/uip application
+    (for execution from FLASH). See examples/README.txt for information
+    about ostest.
+
+  nsh:
+    Configures the NuttShell (nsh) located at examples/nsh.  The
+    Configuration enables only the serial NSH interfaces (the telnet
+    interface should also be functional, but is not enabled in this
+    configuration).
+
+  ostest:
+    This configuration directory, performs a simple OS test using
+    examples/ostest.
+
+  thttpd:
+    This builds the THTTPD web server example using the THTTPD and
+    the examples/thttpd application.
+
+By default, all of these examples are built to be used with the Luminary
+Ethernet Bootloader (you can change the ld.script file in any of these
+sub-directories to change that configuration).

+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery or devkitARM, you simply need to add one of the following
+  configuration options to your .config (or defconfig) file:
+
+    CONFIG_LM3S_CODESOURCERYW=y   : CodeSourcery under Windows
+    CONFIG_LM3S_CODESOURCERYL=y   : CodeSourcery under Linux
+    CONFIG_LM3S_DEVKITARM=y       : devkitARM under Windows
+    CONFIG_LM3S_BUILDROOT=y       : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_LM3S_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows) and devkitARM are Windows native toolchains.
+  The CodeSourcey (for Linux) and NuttX buildroot toolchains are Cygwin and/or Linux
+  native toolchains. There are several limitations to using a Windows based
+  toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+  NOTE 3: I recently (i.e., late 2011) tried building with the CodeSourcery Windows
+  toolchain.  The code worked but required 40 seconds to boot (or even until the
+  status LED illuminates)!!  Know idea why. With the buildroot tools, boot time is
+  a couple of seconds.
+
+IDEs
+^^^^
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project.
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/lm3s,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/lm3s/lm3s_vectors.S.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh ekk-lm3s9b96/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you
+  are building a Cortex-M3 toolchain for Cygwin under Windows.
+
+  NOTE: This is an OABI toolchain.

+
+Stellaris EKK-LM3S9B96 Evaluation Kit Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+    CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+       be set to:
+
+       CONFIG_ARCH=arm
+
+    CONFIG_ARCH_family - For use in C code:
+
+       CONFIG_ARCH_ARM=y
+
+    CONFIG_ARCH_architecture - For use in C code:
+
+       CONFIG_ARCH_CORTEXM3=y
+
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+       CONFIG_ARCH_CHIP=lm3s
+
+    CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+       chip:
+
+       CONFIG_ARCH_CHIP_LM3S9B96
+
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+
+       CONFIG_ARCH_BOARD=ekk-lm3s9b96 (for the Stellaris EKK-LM3S9b96 Evaluation Kit)
+
+    CONFIG_ARCH_BOARD_name - For use in C code
+
+       CONFIG_ARCH_BOARD_EKKLM3S9B96
+
+    CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+       of delay loops
+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_DRAM_SIZE - Describes the installed DRAM (SRAM in this case):
+
+       CONFIG_DRAM_SIZE=0x00018000 (96Kb)
+
+    CONFIG_DRAM_START - The start address of installed DRAM
+
+       CONFIG_DRAM_START=0x20000000
+
+    CONFIG_ARCH_IRQPRIO - The LM3S6918 supports interrupt prioritization
+
+       CONFIG_ARCH_IRQPRIO=y
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+       stack. If defined, this symbol is the size of the interrupt
+        stack in bytes.  If not defined, the user task stacks will be
+      used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.
+
+  There are configurations for disabling support for interrupts GPIO ports.
+  GPIOJ must be disabled because it does not exist on the LM3S6918.
+  Additional interrupt support can be disabled if desired to reduce memory
+  footprint.
+
+    CONFIG_LM3S_DISABLE_GPIOA_IRQS=n
+    CONFIG_LM3S_DISABLE_GPIOB_IRQS=n
+    CONFIG_LM3S_DISABLE_GPIOC_IRQS=n
+    CONFIG_LM3S_DISABLE_GPIOD_IRQS=n
+    CONFIG_LM3S_DISABLE_GPIOE_IRQS=n
+    CONFIG_LM3S_DISABLE_GPIOF_IRQS=n
+    CONFIG_LM3S_DISABLE_GPIOG_IRQS=n
+    CONFIG_LM3S_DISABLE_GPIOH_IRQS=n
+    CONFIG_LM3S_DISABLE_GPIOJ_IRQS=y
+ 
+  LM3S6818 specific device driver settings
+
+    CONFIG_UARTn_SERIAL_CONSOLE - selects the UARTn for the
+       console and ttys0 (default is the UART0).
+    CONFIG_UARTn_RXBUFSIZE - Characters are buffered as received.
+       This specific the size of the receive buffer
+    CONFIG_UARTn_TXBUFSIZE - Characters are buffered before
+       being sent.  This specific the size of the transmit buffer
+    CONFIG_UARTn_BAUD - The configure BAUD of the UART.  Must be
+    CONFIG_UARTn_BITS - The number of bits.  Must be either 7 or 8.
+    CONFIG_UARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
+    CONFIG_UARTn_2STOP - Two stop bits
+
+    CONFIG_SSI0_DISABLE - Select to disable support for SSI0
+    CONFIG_SSI1_DISABLE - Select to disable support for SSI1
+    CONFIG_SSI_POLLWAIT - Select to disable interrupt driven SSI support.
+      Poll-waiting is recommended if the interrupt rate would be to
+      high in the interrupt driven case.
+    CONFIG_SSI_TXLIMIT - Write this many words to the Tx FIFO before
+      emptying the Rx FIFO.  If the SPI frequency is high and this
+      value is large, then larger values of this setting may cause
+      Rx FIFO overrun errors.  Default: half of the Tx FIFO size (4).
+
+    CONFIG_LM3S_ETHERNET - This must be set (along with CONFIG_NET)
+      to build the LM3S Ethernet driver
+    CONFIG_LM3S_ETHLEDS - Enable to use Ethernet LEDs on the board.
+    CONFIG_LM3S_BOARDMAC - If the board-specific logic can provide
+      a MAC address (via lm3s_ethernetmac()), then this should be selected.
+    CONFIG_LM3S_ETHHDUPLEX - Set to force half duplex operation
+    CONFIG_LM3S_ETHNOAUTOCRC - Set to suppress auto-CRC generation
+    CONFIG_LM3S_ETHNOPAD - Set to suppress Tx padding
+    CONFIG_LM3S_MULTICAST - Set to enable multicast frames
+    CONFIG_LM3S_PROMISCUOUS - Set to enable promiscuous mode
+    CONFIG_LM3S_BADCRC - Set to enable bad CRC rejection.
+    CONFIG_LM3S_DUMPPACKET - Dump each packet received/sent to the console.
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each Stellaris EKK-LM3S9b96 Evaluation Kit configuration is maintained in a
+sudirectory and can be selected as follow:
+
+    cd tools
+    ./configure.sh ekk-lm3s9b96/<subdir>
+    cd -
+    . ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  nsh:
+    Configures the NuttShell (nsh) located at examples/nsh.  The
+    Configuration enables both the serial and telnetd NSH interfaces.
+
+    NOTE: As it is configured now, you MUST have a network connected.
+    Otherwise, the NSH prompt will not come up because the Ethernet
+    driver is waiting for the network to come up.  That is probably
+    a bug in the Ethernet driver behavior!
+
+  ostest:
+    This configuration directory, performs a simple OS test using
+    examples/ostest.

+ *   1. Provide lm3s_spiselect() and lm3s_spistatus() functions in your

+ *      logic
+ *   3. The handle returned by up_spiinitialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling

+ZDS-II Compiler Versions
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+Different configurations have been build for this board using ZDS-11
+Versions 4.11.0 and 4.11.1.  You have to check the files */Make.defs
+to see how the build is configured:  Check the definitions of
+ZDSVERSION (if present) and ZDSINSTALLDIR.
+
+NOTE:  Different versions of the ZDS-II compiler may also require
+different versions of .linkcmd and .zdsproj files as well.
+
+Version 4.11.0
+
+  Although it compiles without error, the 4.11.0 compiler generates
+  This is the only version that this code has been built against.
+  
+  Although it compiles without error, the 4.11.0 compiler generates
+  bad code on one of the files, mm/mm_initialize.c.  Below is a simple work-
+  around.

+ 
+   /* Set up global variables */
+
+Version 5.1.1
+
+  On June 22, 2011 I verified that these configurations build successfully
+  with the 5.1.1 ZDS-II version.  All that is required to used ZDS-II is
+  to modify the Make.defs file so that the correct version is used.  That
+  version should also be changed in the (optional) setenv.sh file.
+
+  The above kludge for 4.11.0 is not required.
+
+  I had to make additional changes to the ZDS path in Make.defs (and also
+  in setenv.sh) when the 32-bit ZDS-II tools are installed on my 64-bit
+  Windows 7 system.
+  
+Other Versions
+  If you use any version of ZDS-II other than 4.11.0 or if you install ZDS-II
+  at any location other than the default location, you will have to modify
+  two files:  (1) configs/ez80f910200kitg/*/setenv.sh and (2)
+  configs/ez80f910200kitg/*/Make.defs.
+
+Configuration Subdirectories
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- src/ and include/
+    These directories contain common logic for all ez80f910200kitg
+    configurations.
+
+Variations on the basic ez80f910200kitg configuration are maintained
+in subdirectories.  To configure any specific configuration, do the
+following steps:
+
+   cd <nuttx-top-directory>/tools
+   ./configure.sh ez80f910200kitg/<sub-directory>
+   cd <nuttx-top-directgory>
+   make
+
+Where <sub-directory> is the specific board configuration that you
+wish to build.  The following board-specific configurations are
+available:
+
+- ostest
+    This builds the examples/ostest application for execution from FLASH.
+    See examples/README.txt for information about ostest.
+
+Check out any README.txt files in these <sub-directory>s.

+This is the output from the z16f target from January 31, 2008

+correct and I suspect some system timing issues.

+ZDS-II Compiler Versions
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+Different configurations have been build for this board using ZDS-11
+Versions 4.11.0 and 4.11.1.  You have to check the files */Make.defs
+to see how the build is configured:  Check the definitions of
+ZDSVERSION (if present) and ZDSINSTALLDIR.
+
+NOTE:  Different versions of the ZDS-II compiler may also require
+different versions of .linkcmd and .zdsproj files as well.
+
+Version 4.11.0
+
+  Although it compiles without error, the 4.11.0 compiler generates
+  bad code on one of the files, mm/mm_initialize.c.  Below is a simple work-
+  around.
+
+    --- mm/mm_initialize.c.SAVE	2008-02-13 08:06:46.833857700 -0600

+    {
+       int i;
+ 
+    +#if 0 /* DO NOT CHECK IN */
+       CHECK_ALLOCNODE_SIZE;
+       CHECK_FREENODE_SIZE;
+    +#endif
+ 
+   /* Set up global variables */
+
+   UPDATE:  I don't know if 4.11.1 has this same problem (I bet not since
+   I submitted the bug to ZiLOG), but I have permanently worked around the
+   above problem for all ZiLOG compiler.
+
+Version 5.1.1
+
+  On June 22, 2011 I verified that these configurations build successfully
+  with the 5.1.1 ZDS-II version.  All that is required to used ZDS-II is
+  to modify the Make.defs file so that the correct version is used.  That
+  version should also be changed in the (optional) setenv.sh file.
+
+  The above kludge for 4.11.0 is not required.
+
+  I had to make additional changes to the ZDS path in Make.defs (and also
+  in setenv.sh) when the 32-bit ZDS-II tools are installed on my 64-bit
+  Windows 7 system.
+  
+Other Versions
+
+  If you use any version of ZDS-II other than 4.11.0 or if you install ZDS-II
+  at any location other than the default location, you will have to modify
+  two files:  (1) configs/ez80f910200zco/*/setenv.sh and (2)
+  configs/ez80f910200zco/*/Make.defs.
+
+Configuration Subdirectories
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+src/ and include/
+    These directories contain common logic for all ez80f910200zco
+    configurations.
+
+Variations on the basic ez80f910200zco configuration are maintained
+in subdirectories.  To configure any specific configuration, do the
+following steps:
+
+   cd <nuttx-top-directory>/tools
+   ./configure.sh ez80f910200zco/<sub-directory>
+   cd <nuttx-top-directgory>
+   make
+
+Where <sub-directory> is the specific board configuration that you
+wish to build.  The following board-specific configurations are
+available:
+
+dhcpd:
+    This builds the DCHP server using the examples/dhcpd application
+    (for execution from FLASH.) See examples/README.txt for information
+    about the dhcpd example.
+
+httpd:
+    This builds the uIP web server example using the examples/uip application
+    (for execution from FLASH). See examples/README.txt for information
+    about ostest.
+
+ostest
+    This builds the examples/ostest application for execution from FLASH.
+    See examples/README.txt for information about ostest.
+
+nsh
+    This configuratino builds the NuttShell (NSH).  That code can be
+    found in examples/nsh.  For more information see:  examples/nsh/README.txt
+    and Documentation/NuttShell.html.
+
+nettest
+    This configuration is used for testing the eZ80F91 EMAC driver.  It
+    builds examples/nettest.  See examples/README.txt for more information
+    about nettest.
+
+poll
+    This configuration is also used for testing the eZ80F91 EMAC driver.  It
+    builds examples/poll.  See examples/README.txt for more information
+    about the poll test.
+
+Check out any README.txt files in these <sub-directory>s.

+This is the output from the ez80f910200zcog-d target from February 27, 2009

+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

+

+All features are enabled and all test pass *except* for the round-robin

+test.  However, it appears that some kept the interrupts disabled through-out

+the conduct of that test (I can tell because of the interrupt driven LED

+array on the board does not update when interrupts are disabled).  So I

+suspect that there is something else going on in that test case.

+Development Environment
+=======================
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment because the CodeSourcery Toolchain.  The Raisonance R-Link
+  emulatator and some RIDE7 development tools were used and those tools works
+  only under Windows.
+
+GNU Toolchain Options
+=====================
+
+  Toolchain Configurations
+  ------------------------
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The Atollic Toolchain,
+  3. The devkitARM GNU toolchain,
+  4. Raisonance GNU toolchain, or
+  5. The NuttX buildroot Toolchain (see below).
+
+  Most testing has been conducted using the CodeSourcery toolchain for Windows and
+  that is the default toolchain in most configurations.  To use the Atollic,
+  devkitARM, Raisonance GNU, or NuttX buildroot toolchain, you simply need to
+  add one of the following configuration options to your .config (or defconfig)
+  file:
+
+    CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_STM32_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_STM32_ATOLLIC_LITE=y   : The free, "Lite" version of Atollic toolchain under Windows
+    CONFIG_STM32_ATOLLIC_PRO=y    : The paid, "Pro" version of Atollic toolchain under Windows
+    CONFIG_STM32_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_STM32_RAISONANCE=y     : Raisonance RIDE7 under Windows
+    CONFIG_STM32_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin (default)
+
+  If you change the default toolchain, then you may also have to modify the PATH in
+  the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows), Atollic, devkitARM, and Raisonance toolchains are
+  Windows native toolchains.  The CodeSourcery (for Linux) and NuttX buildroot
+  toolchains are Cygwin and/or Linux native toolchains. There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  The CodeSourcery Toolchain (2009q1)
+  -----------------------------------
+  The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  The Atollic "Pro" and "Lite" Toolchain
+  --------------------------------------
+  One problem that I had with the Atollic toolchains is that the provide a gcc.exe
+  and g++.exe in the same bin/ file as their ARM binaries.  If the Atollic bin/ path
+  appears in your PATH variable before /usr/bin, then you will get the wrong gcc
+  when you try to build host executables.  This will cause to strange, uninterpretable
+  errors build some host binaries in tools/ when you first make.
+
+  The Atollic "Lite" Toolchain
+  ----------------------------
+  The free, "Lite" version of the Atollic toolchain does not support C++ nor
+  does it support ar, nm, objdump, or objdcopy. If you use the Atollic "Lite"
+  toolchain, you will have to set:
+
+    CONFIG_HAVE_CXX=n
+
+  In order to compile successfully.  Otherwise, you will get errors like:
+
+    "C++ Compiler only available in TrueSTUDIO Professional"
+
+  The make may then fail in some of the post link processing because of some of
+  the other missing tools.  The Make.defs file replaces the ar and nm with
+  the default system x86 tool versions and these seem to work okay.  Disable all
+  of the following to avoid using objcopy:
+
+    CONFIG_RRLOAD_BINARY=n
+    CONFIG_INTELHEX_BINARY=n
+    CONFIG_MOTOROLA_SREC=n
+    CONFIG_RAW_BINARY=n
+
+  devkitARM
+  ---------
+  The devkitARM toolchain includes a version of MSYS make.  Make sure that the
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+====
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project (There is a simple RIDE project
+  in the RIDE subdirectory).
+
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/stm32,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/stm32/stm32_vectors.S.  With RIDE, I have to build NuttX
+  one time from the Cygwin command line in order to obtain the pre-built
+  startup object needed by RIDE.
+
+NuttX buildroot Toolchain
+=========================
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh fire-stm32v2/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you are
+  building a Cortex-M3 toolchain for Cygwin under Windows.
+
+DFU and JTAG
+============
+
+  Enbling Support for the DFU Bootloader
+  --------------------------------------
+  The linker files in these projects can be configured to indicate that you
+  will be loading code using STMicro built-in USB Device Firmware Upgrade (DFU)
+  loader or via some JTAG emulator.  You can specify the DFU bootloader by
+  adding the following line:
+
+    CONFIG_STM32_DFU=y
+
+  to your .config file. Most of the configurations in this directory are set
+  up to use the DFU loader.
+
+  If CONFIG_STM32_DFU is defined, the code will not be positioned at the beginning
+  of FLASH (0x08000000) but will be offset to 0x08003000.  This offset is needed
+  to make space for the DFU loader and 0x08003000 is where the DFU loader expects
+  to find new applications at boot time.  If you need to change that origin for some
+  other bootloader, you will need to edit the file(s) ld.script.dfu for the
+  configuration.
+
+  The DFU SE PC-based software is available from the STMicro website,
+  http://www.st.com.  General usage instructions:
+
+  1. Convert the NuttX Intel Hex file (nuttx.hex) into a special DFU
+     file (nuttx.dfu)... see below for details.
+  2. Connect the M3 Wildfire board to your computer using a USB
+     cable.
+  3. Start the DFU loader on the M3 Wildfire board.  You do this by
+     resetting the board while holding the "Key" button.  Windows should
+     recognize that the DFU loader has been installed.
+  3. Run the DFU SE program to load nuttx.dfu into FLASH.
+
+  What if the DFU loader is not in FLASH?  The loader code is available
+  inside of the Demo dirctory of the USBLib ZIP file that can be downloaded
+  from the STMicro Website.  You can build it using RIDE (or other toolchains);
+  you will need a JTAG emulator to burn it into FLASH the first time.
+
+  In order to use STMicro's built-in DFU loader, you will have to get
+  the NuttX binary into a special format with a .dfu extension.  The
+  DFU SE PC_based software installation includes a file "DFU File Manager"
+  conversion program that a file in Intel Hex format to the special DFU
+  format.  When you successfully build NuttX, you will find a file called
+  nutt.hex in the top-level directory.  That is the file that you should
+  provide to the DFU File Manager.  You will end up with a file called
+  nuttx.dfu that you can use with the STMicro DFU SE program.
+
+  Enabling JTAG
+  -------------
+  If you are not using the DFU, then you will probably also need to enable
+  JTAG support.  By default, all JTAG support is disabled but there NuttX
+  configuration options to enable JTAG in various different ways.
+
+  These configurations effect the setting of the SWJ_CFG[2:0] bits in the AFIO
+  MAPR register.  These bits are used to configure the SWJ and trace alternate function I/Os. The SWJ (SerialWire JTAG) supports JTAG or SWD access to the
+  Cortex debug port.  The default state in this port is for all JTAG support
+  to be disable.
+
+  CONFIG_STM32_JTAG_FULL_ENABLE - sets SWJ_CFG[2:0] to 000 which enables full
+    SWJ (JTAG-DP + SW-DP)
+
+  CONFIG_STM32_JTAG_NOJNTRST_ENABLE - sets SWJ_CFG[2:0] to 001 which enable
+    full SWJ (JTAG-DP + SW-DP) but without JNTRST.
+
+  CONFIG_STM32_JTAG_SW_ENABLE - sets SWJ_CFG[2:0] to 010 which would set JTAG-DP
+    disabled and SW-DP enabled
+
+  The default setting (none of the above defined) is SWJ_CFG[2:0] set to 100
+  which disable JTAG-DP and SW-DP.
+
+OpenOCD
+=======
+
+I have also used OpenOCD with the M3 Wildfire.  In this case, I used
+the Olimex USB ARM OCD.  See the script in configs/fire-stm32v2/tools/oocd.sh
+for more information.  Using the script:
+
+1) Start the OpenOCD GDB server
+
+   cd <nuttx-build-directory>
+   configs/fire-stm32v2/tools/oocd.sh $PWD
+
+2) Load Nuttx
+
+   cd <nuttx-built-directory>
+   arm-none-eabi-gdb nuttx
+   gdb> target remote localhost:3333
+   gdb> mon reset
+   gdb> mon halt
+   gdb> load nuttx
+
+3) Running NuttX
+
+   gdb> mon reset
+   gdb> c
+
+LEDs
+====
+
+The M3 Wildfire has 3 LEDs labeled LED1, LED2 and LED3.  These LEDs are not
+used by the NuttX port unless CONFIG_ARCH_LEDS is defined.  In that case, the
+usage by the board port is defined in include/board.h and src/up_autoleds.c.
+The LEDs are used to encode OS-related events as follows:
+
+                                        /* LED1   LED2   LED3 */
+  #define LED_STARTED                0  /* OFF    OFF    OFF */
+  #define LED_HEAPALLOCATE           1  /* ON     OFF    OFF */
+  #define LED_IRQSENABLED            2  /* OFF    ON     OFF */
+  #define LED_STACKCREATED           3  /* OFF    OFF    OFF */
+
+  #define LED_INIRQ                  4  /* NC     NC    ON  (momentary) */
+  #define LED_SIGNAL                 5  /* NC     NC    ON  (momentary) */
+  #define LED_ASSERTION              6  /* NC     NC    ON  (momentary) */
+  #define LED_PANIC                  7  /* NC     NC    ON  (2Hz flashing) */
+  #undef  LED_IDLE                      /* Sleep mode indication not supported */
+
+RTC
+===
+
+  The STM32 RTC may configured using the following settings.
+
+    CONFIG_RTC - Enables general support for a hardware RTC. Specific
+      architectures may require other specific settings.
+    CONFIG_RTC_HIRES - The typical RTC keeps time to resolution of 1
+      second, usually supporting a 32-bit time_t value.  In this case,
+      the RTC is used to &quot;seed&quot; the normal NuttX timer and the
+      NuttX timer provides for higher resoution time. If CONFIG_RTC_HIRES
+      is enabled in the NuttX configuration, then the RTC provides higher
+      resolution time and completely replaces the system timer for purpose of
+      date and time.
+      CONFIG_RTC_FREQUENCY - If CONFIG_RTC_HIRES is defined, then the
+      frequency of the high resolution RTC must be provided.  If CONFIG_RTC_HIRES
+      is not defined, CONFIG_RTC_FREQUENCY is assumed to be one.
+    CONFIG_RTC_ALARM - Enable if the RTC hardware supports setting of an alarm.
+      A callback function will be executed when the alarm goes off
+
+  In hi-res mode, the STM32 RTC operates only at 16384Hz.  Overflow interrupts
+  are handled when the 32-bit RTC counter overflows every 3 days and 43 minutes.
+  A BKP register is incremented on each overflow interrupt creating, effectively,
+  a 48-bit RTC counter.
+
+  In the lo-res mode, the RTC operates at 1Hz.  Overflow interrupts are not handled
+  (because the next overflow is not expected until the year 2106.
+
+   WARNING:  Overflow interrupts are lost whenever the STM32 is powered down.  The
+   overflow interrupt may be lost even if the STM32 is powered down only momentarily.
+   Therefore hi-res solution is only useful in systems where the power is always on.
+
+M3 Wildfire-specific Configuration Options
+============================================
+
+    CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+       be set to:
+
+       CONFIG_ARCH=arm
+
+    CONFIG_ARCH_family - For use in C code:
+
+       CONFIG_ARCH_ARM=y
+
+    CONFIG_ARCH_architecture - For use in C code:
+
+       CONFIG_ARCH_CORTEXM3=y
+
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+       CONFIG_ARCH_CHIP=stm32
+
+    CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+       chip:
+
+       CONFIG_ARCH_CHIP_STM32
+       CONFIG_ARCH_CHIP_STM32F103VET6
+
+    CONFIG_ARCH_BOARD_STM32_CUSTOM_CLOCKCONFIG - Enables special STM32 clock
+       configuration features.
+
+       CONFIG_ARCH_BOARD_STM32_CUSTOM_CLOCKCONFIG=n
+
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+
+       CONFIG_ARCH_BOARD=fire-stm32v2 (for the M3 Wildfire development board)
+
+    CONFIG_ARCH_BOARD_name - For use in C code
+
+       CONFIG_ARCH_BOARD_FIRE_STM32V2=y
+
+    CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+       of delay loops
+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_DRAM_SIZE - Describes the installed DRAM (SRAM in this case):
+
+       CONFIG_DRAM_SIZE=0x00010000 (64Kb)
+
+    CONFIG_DRAM_START - The start address of installed DRAM
+
+       CONFIG_DRAM_START=0x20000000
+
+    CONFIG_ARCH_IRQPRIO - The STM32F103Z supports interrupt prioritization
+
+       CONFIG_ARCH_IRQPRIO=y
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+       stack. If defined, this symbol is the size of the interrupt
+        stack in bytes.  If not defined, the user task stacks will be
+      used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.

+  Timer and I2C devices may need to the following to force power to be applied
+  unconditionally at power up.  (Otherwise, the device is powered when it is
+  initialized).
+
+    CONFIG_STM32_FORCEPOWER
+
+  Timer devices may be used for different purposes.  One special purpose is
+  to generate modulated outputs for such things as motor control.  If CONFIG_STM32_TIMn
+  is defined (as above) then the following may also be defined to indicate that
+  the timer is intended to be used for pulsed output modulation, ADC conversion,
+  or DAC conversion.  Note that ADC/DAC require two definition:  Not only do you have
+  to assign the timer (n) for used by the ADC or DAC, but then you also have to
+  configure which ADC or DAC (m) it is assigned to.
+
+    CONFIG_STM32_TIMn_PWM   Reserve timer n for use by PWM, n=1,..,8
+    CONFIG_STM32_TIMn_ADC   Reserve timer n for use by ADC, n=1,..,8

+    CONFIG_STM32_TIMn_DAC   Reserve timer n for use by DAC, n=1,..,8
+    CONFIG_STM32_TIMn_DACm  Reserve timer n to trigger DACm, n=1,..,8, m=1,..,2
+
+  For each timer that is enabled for PWM usage, we need the following additional
+  configuration settings:
+
+    CONFIG_STM32_TIMx_CHANNEL - Specifies the timer output channel {1,..,4}
+
+  NOTE: The STM32 timers are each capable of generating different signals on
+  each of the four channels with different duty cycles.  That capability is
+  not supported by this driver:  Only one output channel per timer.
+
+  Alternate pin mappings.  The M3 Wildfire board requires only CAN1 remapping
+  On the M3 Wildfire board pin PB9 is wired as TX and pin PB8 is wired as RX.
+  Which then makes the proper connection through the CAN transiver SN65HVD230
+  out to the CAN D-type 9-pn male connector where pin 2 is CANL and pin 7 is CANH.

+      adjustable backlight will be provided using timer 1 to generate
+      various pulse widthes.  The granularity of the settings is
+      determined by CONFIG_LCD_MAXPOWER.  If CONFIG_LCD_PWM (or
+      CONFIG_STM32_TIM1) is not defined, then a simple on/off backlight
+      is provided.
+    CONFIG_LCD_RDSHIFT - When reading 16-bit gram data, there appears
+      to be a shift in the returned data.  This value fixes the offset.
+      Default 5.
+
+    The LCD driver dynamically selects the LCD based on the reported LCD
+    ID value.  However, code size can be reduced by suppressing support for
+    individual LCDs using:
+
+    CONFIG_STM32_AM240320_DISABLE
+    CONFIG_STM32_SPFD5408B_DISABLE
+    CONFIG_STM32_R61580_DISABLE
+
+Configurations
+==============
+
+Each M3 Wildfire configuration is maintained in a sudirectory and
+can be selected as follow:
+
+    cd tools
+    ./configure.sh fire-stm32v2/<subdir>
+    cd -
+    . ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  nsh
+  ---
+    Configure the NuttShell (nsh) located at examples/nsh. The nsh configuration
+    contains support for some built-in applications that can be enabled by making
+    some additional minor change to the configuration file.
+
+    NOTE:  This configuration uses to the mconf configuration tool to control
+    the configuration.  See the section entitled "NuttX Configuration Tool"
+    in the top-level README.txt file.
+
+    STATUS:  The board port is basically functional. Not all features have been
+    verified.  The ENC28J60 network is not yet functional.  Networking is
+    enabled by default in this configuration for testing purposes.  To use this
+    configuration, the network must currently be disabled.  To do this using
+    the mconf configuration tool:
+
+    > make menuconfig
+
+    Then de-select "Networking Support" -> "Networking Support"
+
+    UPDATE:  The primary problem with the ENC29J60 is a v2 board issue:  The
+    SPI FLASH and the ENC28J60 shared the same SPI chip select signal (PA4-SPI1-NSS).
+    In order to finish the debug of the ENC28J60, it may be necessary to lift
+    the SPI FLASH chip select pin from the board.

+ *
+ *   1. Provide logic in stm32_boardinitialize() to configure SPI chip select
+ *      pins.
+ *   2. Provide stm32_spi1/2/3select() and stm32_spi1/2/3status() functions in your
+ *      board-specific logic.  These functions will perform chip selection and
+ *      status operations using GPIOs in the way your board is configured.
+ *   3. Add a calls to up_spiinitialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by up_spiinitialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling

+README
+======
+
+This README discusses issues unique to NuttX configurations for the
+HY-MiniSTM32V development board.

+  - IDEs

+  - Configurations
+
+Development Environment
+=======================
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment because the Raisonance R-Link emulatator and some RIDE7 development tools
+  were used and those tools works only under Windows.
+
+GNU Toolchain Options
+=====================
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. Raisonance GNU toolchain, or
+  4. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery, devkitARM or Raisonance GNU toolchain, you simply need to
+  add one of the following configuration options to your .config (or defconfig)
+  file:
+
+    CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_STM32_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_STM32_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_STM32_RAISONANCE=y     : Raisonance RIDE7 under Windows
+    CONFIG_STM32_BUILDROOT=y	  : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_STM32_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows), devkitARM, and Raisonance toolchains are
+  Windows native toolchains.  The CodeSourcey (for Linux) and NuttX buildroot
+  toolchains are Cygwin and/or Linux native toolchains. There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+====
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project (There is a simple RIDE project
+  in the RIDE subdirectory).
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/stm32,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/stm32/stm32_vectors.S.  With RIDE, I have to build NuttX
+  one time from the Cygwin command line in order to obtain the pre-built
+  startup object needed by RIDE.
+
+NuttX buildroot Toolchain
+=========================
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh hymini-stm32v/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you are
+  building a Cortex-M3 toolchain for Cygwin under Windows.
+
+DFU
+===
+
+  The linker files in these projects can be configured to indicate that you
+  will be loading code using STMicro built-in USB Device Firmware Upgrade (DFU)
+  loader or via some JTAG emulator.  You can specify the DFU bootloader by
+  adding the following line:
+
+    CONFIG_STM32_DFU=y
+
+  to your .config file. Most of the configurations in this directory are set
+  up to use the DFU loader.
+
+  If CONFIG_STM32_DFU is defined, the code will not be positioned at the beginning
+  of FLASH (0x08000000) but will be offset to 0x08003000.  This offset is needed
+  to make space for the DFU loader and 0x08003000 is where the DFU loader expects
+  to find new applications at boot time.  If you need to change that origin for some
+  other bootloader, you will need to edit the file(s) ld.script.dfu for each
+  configuration.
+
+  The DFU SE PC-based software is available from the STMicro website,
+  http://www.st.com.  General usage instructions:
+  
+  1. Convert the NuttX Intel Hex file (nuttx.hex) into a special DFU
+     file (nuttx.dfu)... see below for details.
+  2. Connect the Hy-Mini STM32v board to your computer using a USB
+     cable.
+  3. Start the DFU loader on the Hy-Mini STM32v board.  You do this by
+     resetting the board while holding the "Key" button.  Windows should
+     recognize that the DFU loader has been installed.
+  3. Run the DFU SE program to load nuttx.dfu into FLASH.
+
+  What if the DFU loader is not in FLASH?  The loader code is available
+  inside of the Demo dirctory of the USBLib ZIP file that can be downloaded
+  from the STMicro Website.  You can build it using RIDE (or other toolchains);
+  you will need a JTAG emulator to burn it into FLASH the first time.
+
+  In order to use STMicro's built-in DFU loader, you will have to get
+  the NuttX binary into a special format with a .dfu extension.  The
+  DFU SE PC_based software installation includes a file "DFU File Manager"
+  conversion program that a file in Intel Hex format to the special DFU
+  format.  When you successfully build NuttX, you will find a file called
+  nutt.hex in the top-level directory.  That is the file that you should
+  provide to the DFU File Manager. You will end up with a file called
+  nuttx.dfu that you can use with the STMicro DFU SE program.
+
+LEDs
+====
+
+The HY-MiniSTM32 board provides only two controlable LEDs labeled LED1 and LED2.
+Usage of these LEDs is defined in include/board.h and src/up_leds.c.
+They are encoded as follows:
+
+	SYMBOL				Meaning					LED1*	LED2	
+	-------------------	-----------------------	-------	-------	
+	LED_STARTED			NuttX has been started	OFF		OFF		
+	LED_HEAPALLOCATE	Heap has been allocated	ON		OFF		
+	LED_IRQSENABLED		Interrupts enabled		OFF		ON		
+	LED_STACKCREATED	Idle stack created		ON		OFF		
+	LED_INIRQ			In an interrupt**		OFF		N/C		
+	LED_SIGNAL			In a signal handler***  N/C		ON		
+	LED_ASSERTION		An assertion failed		ON		ON		
+	LED_PANIC			The system has crashed	BLINK	BLINK		
+    LED_IDLE            STM32 is is sleep mode  (Optional, not used)
+
+  * If Nuttx starts correctly, normal state is to have LED1 on and LED2 off.
+ ** LED1 is turned off during interrrupt.
+*** LED2 is turned on during signal handler.
+
+RTC
+===
+
+  The STM32 RTC may configured using the following settings.
+
+    CONFIG_RTC - Enables general support for a hardware RTC. Specific
+      architectures may require other specific settings.
+    CONFIG_RTC_HIRES - The typical RTC keeps time to resolution of 1
+      second, usually supporting a 32-bit time_t value.  In this case,
+      the RTC is used to &quot;seed&quot; the normal NuttX timer and the
+      NuttX timer provides for higher resoution time. If CONFIG_RTC_HIRES
+      is enabled in the NuttX configuration, then the RTC provides higher
+      resolution time and completely replaces the system timer for purpose of
+      date and time.
+      CONFIG_RTC_FREQUENCY - If CONFIG_RTC_HIRES is defined, then the
+      frequency of the high resolution RTC must be provided.  If CONFIG_RTC_HIRES
+      is not defined, CONFIG_RTC_FREQUENCY is assumed to be one.
+    CONFIG_RTC_ALARM - Enable if the RTC hardware supports setting of an alarm. 
+      A callback function will be executed when the alarm goes off
+
+  In hi-res mode, the STM32 RTC operates only at 16384Hz.  Overflow interrupts
+  are handled when the 32-bit RTC counter overflows every 3 days and 43 minutes.
+  A BKP register is incremented on each overflow interrupt creating, effectively,
+  a 48-bit RTC counter.
+
+  In the lo-res mode, the RTC operates at 1Hz.  Overflow interrupts are not handled
+  (because the next overflow is not expected until the year 2106.
+
+   WARNING:  Overflow interrupts are lost whenever the STM32 is powered down.  The
+   overflow interrupt may be lost even if the STM32 is powered down only momentarily.
+   Therefore hi-res solution is only useful in systems where the power is always on.
+
+HY-Mini specific Configuration Options
+============================================
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+	   be set to:
+
+	   CONFIG_ARCH=arm
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_ARM=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_CORTEXM3=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=stm32
+
+	CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+	   chip:
+
+	   CONFIG_ARCH_CHIP_STM32F103VCT6

+       configuration features.
+
+       CONFIG_ARCH_BOARD_STM32_CUSTOM_CLOCKCONFIG=n
+ 
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=hymini-stm32v (for the HY-Mini development board)
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_HYMINI_STM32V=y

+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)

+
+	   CONFIG_DRAM_SIZE=0x0000C000 (48Kb)
+
+	CONFIG_DRAM_START - The start address of installed DRAM
+
+	   CONFIG_DRAM_START=0x20000000
+

+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt

+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.

+    (1) You will probably need to modify nsh/setenv.sh or nsh2/setenv.sh
+        to set up the correct PATH variable for whichever toolchain you
+        may use.
+    (2) Since DfuSe is assumed, this configuration may only work under
+        Cygwin without modification.
+    (3) When any other device other than /dev/console is used for a user
+        interface, (1) linefeeds (\n) will not be expanded to carriage return
+        / linefeeds \r\n). You will need to configure your terminal program
+        to account for this. And (2) input is not automatically echoed so
+        you will have to turn local echo on.
+    (4) Microsoft holds several patents related to the design of
+        long file names in the FAT file system.  Please refer to the
+        details in the top-level COPYING file.  Please do not use FAT
+        long file name unless you are familiar with these patent issues.
+    (5) When built as an NSH add-on command (CONFIG_EXAMPLES_USBMSC_BUILTIN=y),
+        Caution should be used to assure that the SD drive is not in use when
+        the USB storage device is configured.  Specifically, the SD driver
+        should be unmounted like:
+
+        nsh> mount -t vfat /dev/mmcsd0 /mnt/sdcard # Card is mounted in NSH
+        ...
+        nsh> umount /mnd/sdcard                    # Unmount before connecting USB!!!
+        nsh> msconn                                # Connect the USB storage device
+        ...
+        nsh> msdis                                 # Disconnect USB storate device
+        nsh> mount -t vfat /dev/mmcsd0 /mnt/sdcard # Restore the mount
+
+        Failure to do this could result in corruption of the SD card format.

+    following:
+
+    -CONFIGURED_APPS += examples/usbserial
+    +CONFIGURED_APPS += examples/usbterm
+
+    In either the original appconfig file (before configuring)

+ *   are provided by common STM32 logic.  To use this common SPI logic on your
+ *   board:
+ *
+ *   1. Provide logic in stm32_boardinitialize() to configure SPI chip select
+ *      pins.
+ *   2. Provide stm32_spi1/2/3select() and stm32_spi1/2/3status() functions in your
+ *      board-specific logic.  These functions will perform chip selection and
+ *      status operations using GPIOs in the way your board is configured.
+ *   3. Add a calls to up_spiinitialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by up_spiinitialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling
+ *      mmcsd_spislotinitialize(), for example, will bind the SPI driver to
+ *      the SPI MMC/SD driver).

+
+TWR-SER Serial Board Connection
+===============================
+
+The serial board connects into the tower and then maps to the tower pins to
+yet other functions (see TWR-SER.pdf).
+
+For the serial port, the following jumpers are required:
+
+  J15: 1-2 (default)
+  J17: 1-2 (default)
+  J18: 1-2 (default)
+  J19: 1-2 (default)
+
+The two connections map as follows:
+
+  A41 RXD0  - Not connected
+  A42 TXD0  - Not connected
+  A43 RXD1  - ELE_RXD (connects indirectory to DB-9 connector J8)
+  A44 TXD1  - ELE_TXD (connects indirectory to DB-9 connector J8)
+
+Finally, we can conclude that
+
+  UART5 (PTE8/9) is associated with the DB9 connector
+
+Development Environment
+=======================
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment.
+
+GNU Toolchain Options
+=====================
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the CodeSourcery Windows toolchain.  To
+  use the devkitARM or the NuttX GNU toolchain, you simply need to change the
+  the following configuration options to your .config (or defconfig) file:
+
+    CONFIG_KINETIS_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_KINETIS_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_KINETIS_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_KINETIS_BUILDROOT=y	    : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_KINETIS_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows) and devkitARM toolchains are
+  Windows native toolchains.  The CodeSourcey (for Linux) and NuttX buildroot
+  toolchains are Cygwin and/or Linux native toolchains. There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+====
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project.
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/k40,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/kinetis/k40_vectors.S.
+
+NuttX buildroot Toolchain
+=========================
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M4 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M4 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  NOTE:  The NuttX toolchain is an OABI toolchain (vs. the more common EABI)
+  and does not include optimizations for Cortex-M4 (ARMv7E-M).
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh kwikstik-k40/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you are
+  building a Cortex-M4 toolchain for Cygwin under Windows.
+
+KwikStik-K40-specific Configuration Options
+============================================
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This sould
+	   be set to:
+
+	   CONFIG_ARCH=arm
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_ARM=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_CORTEXM4=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=k40
+
+	CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+	   chip:
+
+	   CONFIG_ARCH_CHIP_MK40X256VLQ100
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=kwikstik-k40 (for the KwikStik-K40 development board)
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_KWIKSTIK_K40=y
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - Describes the installed DRAM (SRAM in this case):
+
+	   CONFIG_DRAM_SIZE=0x00010000 (64Kb)
+
+	CONFIG_DRAM_START - The start address of installed DRAM
+
+	   CONFIG_DRAM_START=0x20000000
+
+	CONFIG_ARCH_IRQPRIO - The Kinetis K40 supports interrupt prioritization
+
+	   CONFIG_ARCH_IRQPRIO=y
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	    stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.

+
+  The Lincoln 60 has two serial connectors. The serial console defaults
+  to COM1 (UART0).
+
+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery or devkitARM toolchain, you simply need add one of the
+  following configuration options to your .config (or defconfig) file:
+
+    CONFIG_LPC17_CODESOURCERYW=y   : CodeSourcery under Windows
+    CONFIG_LPC17_CODESOURCERYL=y   : CodeSourcery under Linux
+    CONFIG_LPC17_DEVKITARM=y       : devkitARM under Windows
+    CONFIG_LPC17_BUILDROOT=y       : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_LPC17_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows)and devkitARM are Windows native toolchains.
+  The CodeSourcey (for Linux) and NuttX buildroot toolchains are Cygwin and/or
+  Linux native toolchains. There are several limitations to using a Windows based
+  toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+^^^^
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project (There is a simple RIDE project
+  in the RIDE subdirectory).
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/lpc17xx,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/lpc17x/lpc17_vectors.S.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh lincoln60/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you
+  are building a Cortex-M3 toolchain for Cygwin under Windows.
+
+  NOTE: This is an OABI toolchain.

+
+USB Host Configuration
+^^^^^^^^^^^^^^^^^^^^^^
+
+The Lincoln 60 board supports a USB host interface.  The hidkbd
+example can be used to test this interface.
+
+The NuttShell (NSH) lincoln60 can also be modified in order to support USB
+host operations.  To make these modifications, do the following:
+
+1. First configure to build the NSH configuration from the top-level
+   NuttX directory:
+
+   cd tools
+   ./configure lincoln60/nsh
+   cd ..
+
+2. Then edit the top-level .config file to enable USB host.  Make the
+   following changes:
+
+   CONFIG_LPC17_USBHOST=n
+   CONFIG_USBHOST=n
+   CONFIG_SCHED_WORKQUEUE=y
+
+When this change is made, NSH should be extended to support USB flash
+devices.  When a FLASH device is inserted, you should see a device
+appear in the /dev (pseudo) directory.  The device name should be
+like /dev/sda, /dev/sdb, etc.  The USB mass storage device, is present
+it can be mounted from the NSH command line like:
+
+   ls /dev
+   mount -t vfat /dev/sda /mnt/flash
+
+Files on the connect USB flash device should then be accessible under
+the mountpoint /mnt/flash.
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each Lincoln 60 configuration is maintained in a sudirectory and can be selected
+as follow:
+
+	cd tools
+	./configure.sh lincoln60/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  ostest:
+    Builds the NuttX OS test at apps/examples/ostest.
+
+  nsh:
+    Configures the NuttShell (nsh) located at apps/examples/nsh.  The
+    Configuration enables only the serial NSH interfaces.  See notes
+    above for enabling USB host support in this configuration.

+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux, Mac OS X or Cygwin on Windows can be used for the development 
+  environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using GCC on
+  Mac OS X.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. The NuttX buildroot Toolchain (see below).
+
+  To use a specific toolchain, you simply need to add one of the following
+  configuration options to your .config (or defconfig) file:
+
+    CONFIG_LM3S_CODESOURCERYW=y   : CodeSourcery under Windows
+    CONFIG_LM3S_CODESOURCERYL=y   : CodeSourcery under Linux or on Mac OS X.
+    CONFIG_LM3S_DEVKITARM=y       : devkitARM under Windows
+    CONFIG_LM3S_BUILDROOT=y       : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_LM3S_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows) and devkitARM are Windows native toolchains.
+  The CodeSourcey (for Linux) and NuttX buildroot toolchains are Cygwin and/or Linux
+  native toolchains. There are several limitations to using a Windows based
+  toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+^^^^
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project.
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/lm3s,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/lm3s/lm3s_vectors.S.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  This port was tested with tools built using summon-arm-toolchain; available
+  from https://github.com/esden/summon-arm-toolchain, however the buildroot
+  instructions should apply for other platforms.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh lm3s6432-s2e/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you
+  are building a Cortex-M3 toolchain for Cygwin under Windows.
+
+  NOTE: This is an OABI toolchain.
+
+
+Stellaris MDL-S2E Reference Design Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+	   be set to:
+
+	   CONFIG_ARCH=arm
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_ARM=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_CORTEXM3=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=lm3s
+
+	CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+	   chip:
+
+	   CONFIG_ARCH_CHIP_LM3S6432
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=lm3s6432-s2e (for the Stellaris MDL-S2E Reference Design)
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_LM3S6432S2E
+
+	CONFIG_ARCH_LOOPSPERMSEC - As supplied, calibrated for correct operation
+	   of delay loops assuming 50MHz CPU frequency.
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - Describes the installed DRAM (SRAM in this case):
+
+	   CONFIG_DRAM_SIZE=0x00010000 (64Kb)
+
+	CONFIG_DRAM_START - The start address of installed DRAM
+
+	   CONFIG_DRAM_START=0x20000000
+
+	CONFIG_ARCH_IRQPRIO - The LM3S6918 supports interrupt prioritization
+
+	   CONFIG_ARCH_IRQPRIO=y
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	    stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.
+
+  There are configurations for disabling support for interrupts GPIO ports.
+  GPIOH and GPIOJ must be disabled because they do not exist on the LM3S6432.
+  Additional interrupt support can be disabled if desired to reduce memory
+  footprint - GPIOs C-G are not pinned out on the MDL-S2E board.
+
+	CONFIG_LM3S_DISABLE_GPIOA_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOB_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOC_IRQS=y
+	CONFIG_LM3S_DISABLE_GPIOD_IRQS=y
+	CONFIG_LM3S_DISABLE_GPIOE_IRQS=y
+	CONFIG_LM3S_DISABLE_GPIOF_IRQS=y
+	CONFIG_LM3S_DISABLE_GPIOG_IRQS=y
+	CONFIG_LM3S_DISABLE_GPIOH_IRQS=y
+	CONFIG_LM3S_DISABLE_GPIOJ_IRQS=y
+ 
+  LM3S6432 specific device driver settings
+
+	CONFIG_UARTn_DISABLE
+	   The TX and RX pins for UART1 share I/O pins with the TX and RX pins
+	   for SSI0.  To avoid conflicts, only one of SSI0 and UART1 should
+	   be enabled in a configuration.
+	CONFIG_UARTn_SERIAL_CONSOLE - selects the UARTn for the
+	   console and ttys0 (default is UART1).
+	CONFIG_UARTn_RXBUFSIZE - Characters are buffered as received.
+	   This specific the size of the receive buffer
+	CONFIG_UARTn_TXBUFSIZE - Characters are buffered before
+	   being sent.  This specific the size of the transmit buffer
+	CONFIG_UARTn_BAUD - The configure BAUD of the UART.  Must be
+	CONFIG_UARTn_BITS - The number of bits.  Must be either 7 or 8.
+	CONFIG_UARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
+	CONFIG_UARTn_2STOP - Two stop bits
+
+	CONFIG_SSI0_DISABLE - Select to disable support for SSI0
+	  The TX and RX pins for SSI0 share I/O pins with the TX and RX pins
+	  for UART1.  To avoid conflicts, only one of SSI0 and UART1 should
+	  be enabled in a configuration.
+	CONFIG_SSI1_DISABLE - Select to disable support for SSI1
+	  Note that the LM3S6432 only has one SSI, so SSI1 should always be
+	  disabled.
+	CONFIG_SSI_POLLWAIT - Select to disable interrupt driven SSI support.
+	  Poll-waiting is recommended if the interrupt rate would be to
+	  high in the interrupt driven case.
+	CONFIG_SSI_TXLIMIT - Write this many words to the Tx FIFO before
+	  emptying the Rx FIFO.  If the SPI frequency is high and this
+	  value is large, then larger values of this setting may cause
+	  Rx FIFO overrun errors.  Default: half of the Tx FIFO size (4).
+
+	CONFIG_LM3S_ETHERNET - This must be set (along with CONFIG_NET)
+	  to build the LM3S Ethernet driver
+	CONFIG_LM3S_ETHLEDS - Enable to use Ethernet LEDs on the board.
+	CONFIG_LM3S_BOARDMAC - This should be set in order to use the
+	  MAC address configured in the flash USER registers.
+	CONFIG_LM3S_ETHHDUPLEX - Set to force half duplex operation
+	CONFIG_LM3S_ETHNOAUTOCRC - Set to suppress auto-CRC generation
+	CONFIG_LM3S_ETHNOPAD - Set to suppress Tx padding
+	CONFIG_LM3S_MULTICAST - Set to enable multicast frames
+	CONFIG_LM3S_PROMISCUOUS - Set to enable promiscuous mode
+	CONFIG_LM3S_BADCRC - Set to enable bad CRC rejection.
+	CONFIG_LM3S_DUMPPACKET - Dump each packet received/sent to the console.
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each Stellaris MDL-S2E Reference Design configuration is maintained in a
+sudirectory and can be selected as follow:
+
+	cd tools
+	./configure.sh lm3s6432-s2e/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  nsh:
+    Configures the NuttShell (nsh) located at examples/nsh.  The
+    Configuration enables both the serial and telnetd NSH interfaces.
+
+    NOTE: As it is configured now, you MUST have a network connected.
+    Otherwise, the NSH prompt will not come up because the Ethernet
+    driver is waiting for the network to come up.  That is probably
+    a bug in the Ethernet driver behavior!
+
+  ostest:
+    This configuration directory, performs a simple OS test using
+    examples/ostest.
+
+    NOTE: as the configuration stands, ostest will hang during the 
+    semaphore test.  This has not been debugged.

+OLED
+^^^^
+
+  The Evaluation Kit includes an OLED graphics display. Features:
+
+  - RiT P14201 series display
+  - 128 columns by 96 rows
+  - 4-bit, 16-level gray scale.
+  - High-contrast (typ. 500:1)
+  - Excellent brightness (120 cd/m2)
+  - Fast 10 us response.
+
+  The OLED display has a built-in controller IC with synchronous serial and
+  parallel interfaces (SSD1329). Synchronous serial (SSI) is used on the EVB.
+  The SSI port is shared with the microSD card slot.
+
+  - PC7: OLED display data/control select (D/Cn)
+  - PA3: OLED display chip select (CSn)
+
+  NOTE:  Newer versions of the LM3S6965 Evaluation Kit has an OSAM 128x64x4 OLED
+  display.  Some tweaks to drivers/lcd/p14201.c would be required to support that
+  LCD.
+
+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery or devkitARM, you simply need to add one of the following
+  configuration options to your .config (or defconfig) file:
+
+    CONFIG_LM3S_CODESOURCERYW=y   : CodeSourcery under Windows
+    CONFIG_LM3S_CODESOURCERYL=y   : CodeSourcery under Linux
+    CONFIG_LM3S_DEVKITARM=y       : devkitARM under Windows
+    CONFIG_LM3S_BUILDROOT=y       : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_LM3S_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows) and devkitARM are Windows native toolchains.
+  The CodeSourcey (for Linux) and NuttX buildroot toolchains are Cygwin and/or Linux
+  native toolchains. There are several limitations to using a Windows based
+  toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+  NOTE 3: I recently (i.e., late 2011) tried building with the CodeSourcery Windows
+  toolchain.  The code worked but required 40 seconds to boot (or even until the
+  status LED illuminates)!!  Know idea why. With the buildroot tools, boot time is
+  a couple of seconds.
+
+IDEs
+^^^^
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project.
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/lm3s,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/lm3s/lm3s_vectors.S.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh lm3s6965-ek/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you
+  are building a Cortex-M3 toolchain for Cygwin under Windows.
+
+  NOTE: This is an OABI toolchain.
+
+USB Device Controller Functions
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  Device Overview
+
+    An FT2232 device from Future Technology Devices International Ltd manages
+    USB-to-serial conversion. The FT2232 is factory configured by Luminary
+    Micro to implement a JTAG/SWD port (synchronous serial) on channel A and
+    a Virtual COM Port (VCP) on channel B. This feature allows two simultaneous
+    communications links between the host computer and the target device using
+    a single USB cable. Separate Windows drivers for each function are provided
+    on the Documentation and Software CD.
+
+  Debugging with JTAG/SWD
+
+    The FT2232 USB device performs JTAG/SWD serial operations under the control 
+    of the debugger or the Luminary Flash Programmer.  It also operate as an
+    In-Circuit Debugger Interface (ICDI), allowing debugging of any external
+    target board.  Debugging modes:
+
+    MODE DEBUG FUNCTION       USE                         SELECTED BY
+    1    Internal ICDI        Debug on-board LM3S6965     Default Mode

+    2    ICDI out to JTAG/SWD The EVB is used as a USB    Connecting to an external
+         header               to SWD/JTAG interface to    target and starting debug

+                              the EVB.
+
+  Virtual COM Port
+
+    The Virtual COM Port (VCP) allows Windows applications (such as HyperTerminal)
+    to communicate with UART0 on the LM3S6965 over USB. Once the FT2232 VCP
+    driver is installed, Windows assigns a COM port number to the VCP channel.

+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=lm3s6965-ek (for the Stellaris LM3S6965 Evaluation Kit)
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_LM3S6965EK
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - Describes the installed DRAM (SRAM in this case):
+
+	   CONFIG_DRAM_SIZE=0x00010000 (64Kb)
+
+	CONFIG_DRAM_START - The start address of installed DRAM
+
+	   CONFIG_DRAM_START=0x20000000
+
+	CONFIG_ARCH_IRQPRIO - The LM3S6918 supports interrupt prioritization
+
+	   CONFIG_ARCH_IRQPRIO=y
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	    stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.
+
+  There are configurations for disabling support for interrupts GPIO ports.
+  GPIOJ must be disabled because it does not exist on the LM3S6918.
+  Additional interrupt support can be disabled if desired to reduce memory
+  footprint.
+
+	CONFIG_LM3S_DISABLE_GPIOA_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOB_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOC_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOD_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOE_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOF_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOG_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOH_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOJ_IRQS=y
+ 
+  LM3S6818 specific device driver settings
+
+	CONFIG_UARTn_SERIAL_CONSOLE - selects the UARTn for the
+	   console and ttys0 (default is the UART0).
+	CONFIG_UARTn_RXBUFSIZE - Characters are buffered as received.
+	   This specific the size of the receive buffer
+	CONFIG_UARTn_TXBUFSIZE - Characters are buffered before
+	   being sent.  This specific the size of the transmit buffer
+	CONFIG_UARTn_BAUD - The configure BAUD of the UART.  Must be
+	CONFIG_UARTn_BITS - The number of bits.  Must be either 7 or 8.
+	CONFIG_UARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
+	CONFIG_UARTn_2STOP - Two stop bits
+
+	CONFIG_SSI0_DISABLE - Select to disable support for SSI0
+	CONFIG_SSI1_DISABLE - Select to disable support for SSI1
+	CONFIG_SSI_POLLWAIT - Select to disable interrupt driven SSI support.
+	  Poll-waiting is recommended if the interrupt rate would be to
+	  high in the interrupt driven case.
+	CONFIG_SSI_TXLIMIT - Write this many words to the Tx FIFO before
+	  emptying the Rx FIFO.  If the SPI frequency is high and this
+	  value is large, then larger values of this setting may cause
+	  Rx FIFO overrun errors.  Default: half of the Tx FIFO size (4).
+
+	CONFIG_LM3S_ETHERNET - This must be set (along with CONFIG_NET)
+	  to build the LM3S Ethernet driver
+	CONFIG_LM3S_ETHLEDS - Enable to use Ethernet LEDs on the board.
+	CONFIG_LM3S_BOARDMAC - If the board-specific logic can provide
+	  a MAC address (via lm3s_ethernetmac()), then this should be selected.
+	CONFIG_LM3S_ETHHDUPLEX - Set to force half duplex operation
+	CONFIG_LM3S_ETHNOAUTOCRC - Set to suppress auto-CRC generation
+	CONFIG_LM3S_ETHNOPAD - Set to suppress Tx padding
+	CONFIG_LM3S_MULTICAST - Set to enable multicast frames
+	CONFIG_LM3S_PROMISCUOUS - Set to enable promiscuous mode
+	CONFIG_LM3S_BADCRC - Set to enable bad CRC rejection.
+	CONFIG_LM3S_DUMPPACKET - Dump each packet received/sent to the console.
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each Stellaris LM3S6965 Evaluation Kit configuration is maintained in a
+sudirectory and can be selected as follow:
+
+	cd tools
+	./configure.sh lm3s6965-ek/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  nsh:
+    Configures the NuttShell (nsh) located at examples/nsh.  The
+    Configuration enables both the serial and telnetd NSH interfaces.
+
+    NOTE: As it is configured now, you MUST have a network connected.
+    Otherwise, the NSH prompt will not come up because the Ethernet
+    driver is waiting for the network to come up.  That is probably
+    a bug in the Ethernet driver behavior!
+
+    Network File System (NFS) support can be added by setting the
+    following in your configuration file:
+
+      CONFIG_NFS=y
+  nx:
+    And example using the NuttX graphics system (NX).  This example
+    uses the P14201 OLED driver.
+
+  ostest:
+    This configuration directory, performs a simple OS test using
+    examples/ostest.

+  - PA3: OLED display chip select (CSn)
+
+  NOTE:  Newer versions of the LM3S8962 Evaluation Kit has an OSAM 128x64x4 OLED
+  display.  Some tweaks to drivers/lcd/p14201.c would be required to support that
+  LCD.
+
+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery or devkitARM, you simply need to add one of the following
+  configuration options to your .config (or defconfig) file:
+
+    CONFIG_LM3S_CODESOURCERYW=y   : CodeSourcery under Windows
+    CONFIG_LM3S_CODESOURCERYL=y   : CodeSourcery under Linux
+    CONFIG_LM3S_DEVKITARM=y       : devkitARM under Windows
+    CONFIG_LM3S_BUILDROOT=y       : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_LM3S_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows) and devkitARM are Windows native toolchains.
+  The CodeSourcey (for Linux) and NuttX buildroot toolchains are Cygwin and/or Linux
+  native toolchains. There are several limitations to using a Windows based
+  toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+^^^^
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project.  Here are a few tip before you
+  start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/lm3s,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/lm3s/lm3s_vectors.S.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh lm3s8962-ek/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you
+  are building a Cortex-M3 toolchain for Cygwin under Windows.
+
+  NOTE: This is an OABI toolchain.
+
+USB Device Controller Functions
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  Device Overview
+
+    An FT2232 device from Future Technology Devices International Ltd manages
+    USB-to-serial conversion. The FT2232 is factory configured by Luminary
+    Micro to implement a JTAG/SWD port (synchronous serial) on channel A and
+    a Virtual COM Port (VCP) on channel B. This feature allows two simultaneous
+    communications links between the host computer and the target device using
+    a single USB cable. Separate Windows drivers for each function are provided
+    on the Documentation and Software CD.
+
+  Debugging with JTAG/SWD
+
+    The FT2232 USB device performs JTAG/SWD serial operations under the control 
+    of the debugger or the Luminary Flash Programmer.  It also operate as an
+    In-Circuit Debugger Interface (ICDI), allowing debugging of any external
+    target board.  Debugging modes:
+
+    MODE DEBUG FUNCTION       USE                         SELECTED BY
+    1    Internal ICDI        Debug on-board LM3S8962     Default Mode

+    2    ICDI out to JTAG/SWD The EVB is used as a USB    Connecting to an external
+         header               to SWD/JTAG interface to    target and starting debug

+                              the EVB.
+
+  Virtual COM Port
+
+    The Virtual COM Port (VCP) allows Windows applications (such as HyperTerminal)
+    to communicate with UART0 on the LM3S8962 over USB. Once the FT2232 VCP
+    driver is installed, Windows assigns a COM port number to the VCP channel.
+
+Stellaris LM3S8962 Evaluation Kit Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+	   be set to:
+
+	   CONFIG_ARCH=arm
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_ARM=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_CORTEXM3=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=lm3s
+
+	CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+	   chip:
+
+	   CONFIG_ARCH_CHIP_LM3S8962
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=lm3s8962-ek (for the Stellaris LM3S8962 Evaluation Kit)
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_LM3S8962EK
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - Describes the installed DRAM (SRAM in this case):
+
+	   CONFIG_DRAM_SIZE=0x00010000 (64Kb)
+
+	CONFIG_DRAM_START - The start address of installed DRAM
+
+	   CONFIG_DRAM_START=0x20000000
+
+	CONFIG_ARCH_IRQPRIO - The LM3S6918 supports interrupt prioritization
+
+	   CONFIG_ARCH_IRQPRIO=y
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	    stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.
+
+  There are configurations for disabling support for interrupts GPIO ports.
+  GPIOJ must be disabled because it does not exist on the LM3S6918.
+  Additional interrupt support can be disabled if desired to reduce memory
+  footprint.
+
+	CONFIG_LM3S_DISABLE_GPIOA_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOB_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOC_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOD_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOE_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOF_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOG_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOH_IRQS=n
+	CONFIG_LM3S_DISABLE_GPIOJ_IRQS=y
+ 
+  LM3S6818 specific device driver settings
+
+	CONFIG_UARTn_SERIAL_CONSOLE - selects the UARTn for the
+	   console and ttys0 (default is the UART0).
+	CONFIG_UARTn_RXBUFSIZE - Characters are buffered as received.
+	   This specific the size of the receive buffer
+	CONFIG_UARTn_TXBUFSIZE - Characters are buffered before
+	   being sent.  This specific the size of the transmit buffer
+	CONFIG_UARTn_BAUD - The configure BAUD of the UART.  Must be
+	CONFIG_UARTn_BITS - The number of bits.  Must be either 7 or 8.
+	CONFIG_UARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
+	CONFIG_UARTn_2STOP - Two stop bits
+
+	CONFIG_SSI0_DISABLE - Select to disable support for SSI0
+	CONFIG_SSI1_DISABLE - Select to disable support for SSI1
+	CONFIG_SSI_POLLWAIT - Select to disable interrupt driven SSI support.
+	  Poll-waiting is recommended if the interrupt rate would be to
+	  high in the interrupt driven case.
+	CONFIG_SSI_TXLIMIT - Write this many words to the Tx FIFO before
+	  emptying the Rx FIFO.  If the SPI frequency is high and this
+	  value is large, then larger values of this setting may cause
+	  Rx FIFO overrun errors.  Default: half of the Tx FIFO size (4).
+
+	CONFIG_LM3S_ETHERNET - This must be set (along with CONFIG_NET)
+	  to build the LM3S Ethernet driver
+	CONFIG_LM3S_ETHLEDS - Enable to use Ethernet LEDs on the board.
+	CONFIG_LM3S_BOARDMAC - If the board-specific logic can provide
+	  a MAC address (via lm3s_ethernetmac()), then this should be selected.
+	CONFIG_LM3S_ETHHDUPLEX - Set to force half duplex operation
+	CONFIG_LM3S_ETHNOAUTOCRC - Set to suppress auto-CRC generation
+	CONFIG_LM3S_ETHNOPAD - Set to suppress Tx padding
+	CONFIG_LM3S_MULTICAST - Set to enable multicast frames
+	CONFIG_LM3S_PROMISCUOUS - Set to enable promiscuous mode
+	CONFIG_LM3S_BADCRC - Set to enable bad CRC rejection.
+	CONFIG_LM3S_DUMPPACKET - Dump each packet received/sent to the console.
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each Stellaris LM3S8962 Evaluation Kit configuration is maintained in a
+sudirectory and can be selected as follow:
+
+	cd tools
+	./configure.sh lm3s8962-ek/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  nsh:
+    Configures the NuttShell (nsh) located at examples/nsh.  The
+    Configuration enables both the serial and telnetd NSH interfaces.
+
+    NOTE: As it is configured now, you MUST have a network connected.
+    Otherwise, the NSH prompt will not come up because the Ethernet
+    driver is waiting for the network to come up.  That is probably
+    a bug in the Ethernet driver behavior!
+
+  ostest:
+    This configuration directory, performs a simple OS test using
+    examples/ostest.

+  gpio1[11] - LED D3                J10-17  LED2
+  gpio0[7]  - User Button SW2       J8-25   BTN1
+
+  Console
+  -------
+
+  The LPC4330-Xplorer default console is the USB1 virtual COM port (VCOM).
+
+Status
+======
+
+  This is the current status of the LPC43xx port:
+
+  - The basic OS test configuration and the basic NSH configurations
+    are present and fully verified.  This includes:  SYSTICK system time,
+    pin and GPIO configuration, and serial console support.  A SPIFI
+    MTD driver is also in place but requires further verification.
+
+  - The following drivers have been copied from the LPC17xx port, but
+    require integration into the LPC43xx.  This integration should
+    consist of:
+
+    - Remove LPC17xx power, clocking, and pin configuration logic.
+    - Adding of clock source and frequency to the board.h file.
+    - Adding of LPC43 clock connection and pin configuration logic.
+ 
+    Within any luck, these drivers should come up very quickly:
+ 
+    - lpc43_adc.c,
+    - lpc43_dac.c,
+    - lpc43_gpdma.c,
+    - lpc43_i2c.c,
+    - lpc43_spi.c, and
+    - lpc43_ssp.c
+
+    These LPC17xx drivers were not brought into the LPC43xx port because
+    it appears the these peripherals have been completely redesigned:
+
+    - CAN,
+    - Ethernet,
+    - USB device, and
+    - USB host.
+
+    The following LPC43xx peripherals are unsupported.  Some may be
+    compatible with the LPC17xx, but there is no LPC17xx driver to be
+    ported:
+
+    - SD/MMC,
+    - EMC,
+    - USB0,
+    - USB1,
+    - Ethernet,
+    - LCD,
+    - SCT,
+    - Timers 0-3
+    - MCPWM,
+    - QEI,
+    - Alarm timer,
+    - WWDT,
+    - RTC,
+    - Event monitor, and
+    - CAN,
+
+    For the missing drivers some of these can be leveraged from other
+    MCUs that appear to support the same peripheral IP.
+
+    - USB0 appears to be the same as the USB OTG peripheral for the
+      LPC31xx.  It should be possible to drop in the LPC31xx driver
+      with a small porting effort.
+
+    - The Ethernet block looks to be based on the same IP as the
+      STM32 Ethernet and, as a result, it should be possible to leverage
+      the STM32 Ethernet driver with a little more effort.
+
+Development Environment
+=======================
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment.
+
+GNU Toolchain Options
+=====================
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The Code Red GNU toolchain,
+  2. The CodeSourcery GNU toolchain,
+  3. The Atollic Toolchain,
+  4. The devkitARM GNU toolchain,
+  5. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery or devkitARM toolchain, you simply need add one of the
+  following configuration options to your .config (or defconfig) file:
+
+    CONFIG_LPC43_CODEREDW=y       : Code Red "RedSuite" under Windows
+    CONFIG_LPC43_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_LPC43_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_LPC43_ATOLLIC_LITE=y   : The free, "Lite" version of Atollic toolchain under Windows
+    CONFIG_LPC43_ATOLLIC_PRO=y    : The paid, "Pro" version of Atollic toolchain under Windows
+    CONFIG_LPC43_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_LPC43_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_LPC43_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the Code Red, CodeSourcery (for Windows), Atollic and devkitARM toolchains
+  are Windows native toolchains.  The CodeSourcery (for Linux) and NuttX buildroot
+  toolchains are Cygwin and/or Linux native toolchains. There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  The CodeSourcery Toolchain (2009q1)
+  -----------------------------------
+  The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  The Atollic "Pro" and "Lite" Toolchain
+  --------------------------------------
+  One problem that I had with the Atollic toolchains is that the provide a gcc.exe
+  and g++.exe in the same bin/ file as their ARM binaries.  If the Atollic bin/ path
+  appears in your PATH variable before /usr/bin, then you will get the wrong gcc
+  when you try to build host executables.  This will cause to strange, uninterpretable
+  errors build some host binaries in tools/ when you first make.
+
+  Also, the Atollic toolchains are the only toolchains that have built-in support for
+  the FPU in these configurations.  If you plan to use the Cortex-M4 FPU, you will
+  need to use the Atollic toolchain for now.  See the FPU section below for more
+  information.
+
+  The Atollic "Lite" Toolchain
+  ----------------------------
+  The free, "Lite" version of the Atollic toolchain does not support C++ nor
+  does it support ar, nm, objdump, or objdcopy. If you use the Atollic "Lite"
+  toolchain, you will have to set:
+
+    CONFIG_HAVE_CXX=n
+
+  In order to compile successfully.  Otherwise, you will get errors like:
+
+    "C++ Compiler only available in TrueSTUDIO Professional"
+
+  The make may then fail in some of the post link processing because of some of
+  the other missing tools.  The Make.defs file replaces the ar and nm with
+  the default system x86 tool versions and these seem to work okay.  Disable all
+  of the following to avoid using objcopy:
+
+    CONFIG_RRLOAD_BINARY=n
+    CONFIG_INTELHEX_BINARY=n
+    CONFIG_MOTOROLA_SREC=n
+    CONFIG_RAW_BINARY=n
+
+  devkitARM
+  ---------
+  The devkitARM toolchain includes a version of MSYS make.  Make sure that the
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+====
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project .
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/lpc43xx,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/common/up_vectors.S.
+
+Code Red IDE/Tools
+^^^^^^^^^^^^^^^^^^
+
+  Booting the LPCLink
+  -------------------
+
+  The first step is to activate the LPCLink's boot mode.  Some general
+  instructions to do this are provided here:
+
+    http://support.code-red-tech.com/CodeRedWiki/BootingLPCLink
+
+  For my RedSuite installation path, that can be done using the following
+  steps in a Cygwin bash shell:
+
+    $ /cygdrive/c/code_red/RedSuite_4.2.3_379/redsuite/bin/Scripts/bootLPCXpresso.cmd winusb
+    Booting LPC-Link with LPCXpressoWIN.enc
+    Press any key to continue . . . 
+
+  The same file logic can be found the less restrictive LPCXpresso package at:
+
+    /cygdrive/c/nxp/LPCXpresso_4.2.3_292/lpcxpresso/bin
+
+  (The "free" RedSuite version has a download limit of 8K; the "free" LPCXpresso
+  version has a download limit of 128K).
+
+  NOTE that the following alias is defined in the setenv.sh file and
+  can be used to enter the boot mode with a simpler command:
+
+    alias lpc43xx='${SCRIPT_BIN}/Scripts/bootLPCXpresso.cmd winusb'
+
+  Be default, the setenv.sh scripts uses the LPCXpresso path shown above.
+  Once setenv.sh has been sources, then entering boot mode becomes simply:
+
+    $ lpc43xx
+    Booting LPC-Link with LPCXpressoWIN.enc
+    Press any key to continue . . . 
+
+  Using GDB
+  ---------
+
+  The underlying debugger within Red Suite/LPCXpresso is GDB.  That GDB
+  used from the command line.  The GDB configuration details for command
+  line use are on Code Red Wiki:
+
+    http://support.code-red-tech.com/CodeRedWiki/UsingGDB
+
+  and is also summarized here (see the full Wiki for additional details
+  and options).
+
+  The Code Red Debug Driver implements the GDB "remote" protocol to allow
+  connection to debug targets.  To start a debug session using GDB, use
+  following steps:
+
+    arm-none-eabi-gdb executable.axf                  : Start GDB and name the debug image
+    target extended-remote | <debug driver> <options> : Start debug driver, connect to target
+    load                                              : Load image and download to target
+
+  The where <debug driver> is crt_emu_lpc18_43_nxp for LPC18xx and LPC43xx.
+  Your PATH variable should be set up so that the debug driver executable
+  can be found.  For my installation, the driver for the LPC18xx and LPC43xx
+  is located at:
+
+    /cygdrive/c/code_red/RedSuite_4.2.3_379/redsuite/bin/crt_emu_lpc18_43_nxp.exe, OR
+    /cygdrive/c/nxp/LPCXpresso_4.2.3_292/lpcxpresso/bin/crt_emu_lpc18_43_nxp.exe
+
+  And <options> are:
+
+    -n set information level for the debug driver. n should be 2, 3 or 4.
+        2 should be sufficient in most circumstances 
+
+    -p<part> is the target device to connect to and you should use
+        <part>=LPC4330.
+
+    -wire=<probe> specifies the debug probe.  For LPCLink on Windows 7 use
+        <probe>=winusb.  The 128K free version only supports the LPC-Link
+        and RedProbe debug probes. Other JTAG interfaces are supported in
+        the full version.
+
+  Thus the correct invocation for the LPC4330 under Windows7 would be:
+
+    target extended-remote | crt_emu_lpc18_43_nxp -2 -pLPC4330 -wire=winusb
+
+  DDD.  This command can be used to start GDB under the graphics front-end
+  DDD:
+
+    $ ddd --debugger arm-none-eabi-gdb nuttx &
+
+  NOTE 1:  Don't forget to put the LPCLink in boot mode as described above
+  before starting GDB.  So a typical session might look like this:
+
+    $ lpc43xx
+    Booting LPC-Link with LPCXpressoWIN.enc
+    Press any key to continue . . . 
+
+    $ arm-none-eabi-gdb nuttx
+    (gdb) target extended-remote | crt_emu_lpc18_43_nxp -2 -pLPC4330 -wire=winusb
+    (gdb) load
+    (gdb) r
+    (gdb) c
+
+  NOTE 2:  Don't forget to enable CONFIG_DEBUG_SYMBOLS=y in your NuttX
+  configuration file when you build NuttX.  That option is necessary to build
+  in debugging symbols.
+
+  NOTE 3:  There are few things that NuttX has to do differently if you
+  are using a debugger.  Make sure that you also set CONFIG_DEBUG=y.  Nothing
+  also is needed and no debug output will be generated; but NuttX will
+  use CONFIG_DEBUG=y to mean that a debugger is attached and will deal
+  with certain resets and debug controls appropriately.
+
+  So you should have:
+
+    CONFIG_DEBUG=y
+    CONFIG_DEBUG_SYMBOLS=y
+
+  NOTE 4: Every time that you control-C out of the command line GDB, you
+  leave a copy of the Code Red debugger (crt_emu_lpc18_43_nxp) running.  I
+  have found that if you have these old copies of the debugger running, 
+  hen strange things can happen when start yet another copy of the
+  debugger (I suspect that GDB may be talking with the wrong debugger).
+
+  If you exit GDB with quit (not control-C), it seems to clean-up okay.
+  But I have taken to keeping a Process Explorer window open all of the
+  time to keep track of how many of these bad processes have been created.
+
+  NOTE 5: There is also a certain function that is causing some problems.
+  The very first thing that the start-up logic does is call a function
+  called lpc43_softreset() which resets most of the peripherals.  But it
+  also causes some crashes... I think because the resets are causing some
+  interrupts.
+
+  I put a big delay in the soft reset logic between resetting and clearing
+  pending interrupts  and that seems to help some but I am not confident
+  that that is a fix.  I think that the real fix might be to just eliminated
+  this lpc43_softreset() function if we determine that it is not needed.
+
+  If you step over lpc43_softreset() after loading the coding (using the 'n'
+  command), then everything seems work okay.
+
+  Troubleshooting
+  ---------------
+
+  This page provides some troubleshooting information that you can use to
+  verify that the LPCLink is working correctly:
+
+    http://support.code-red-tech.com/CodeRedWiki/LPCLinkDiagnostics
+
+  Command Line Flash Programming
+  ------------------------------
+
+  The LPC18xx/LPC43xx debug driver can also be used to program the LPC43xx
+  flash directly from the command line.  The script flash.sh that may be
+  found in the configs/lpc4330-xplorer/scripts directory can do that with
+  a single command line command.
+
+  Executing from SPIFI
+  --------------------
+
+  By default, the configurations here assume that you are executing directly
+  from SRAM.
+
+    CONFIG_BOOT_SRAM=y             : Executing in SRAM
+    CONFIG_LPC43_CODEREDW=y        : Code Red under Windows
+
+  To execute from SPIFI, you would need to set:
+
+    CONFIG_BOOT_SPIFI=y            : Executing from SPIFI
+    CONFIG_DRAM_SIZE=(128*1024)    : SRAM Bank0 size
+    CONFIG_DRAM_START=0x10000000   : SRAM Bank0 base address

+NuttX buildroot Toolchain
+=========================
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh lpc4330-xplorer/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you
+  are building a Cortex-M3 toolchain for Cygwin under Windows.
+
+  NOTE: This is an OABI toolchain.
+
+Serial Console
+==============
+
+The LPC4330 Xplorer does not have RS-232 drivers or serial connectors on board.
+USART0 and UART1 are available on J8 as follows:
+
+  ------ ------ -----------------------
+  SIGNAL J8 PIN   LPC4330FET100 PIN
+                  (TFBGA100 package)
+  ------ ------ -----------------------

+  ------ ------ -----------------------
+
+  GND  is available on J8 pin 1
+  5V   is available on J8 pin 2
+  VBAT is available on J8 pin 3
+
+FPU
+===
+
+FPU Configuration Options
+-------------------------
+
+There are two version of the FPU support built into the most NuttX Cortex-M4
+ports.  The current LPC43xx port support only one of these options, the "Non-
+Lazy Floating Point Register Save".  As a consequence, CONFIG_ARMV7M_CMNVECTOR
+must be defined in *all* LPC43xx configuration files.
+
+1. Lazy Floating Point Register Save.
+
+   This is an untested implementation that saves and restores FPU registers
+   only on context switches.  This means: (1) floating point registers are
+   not stored on each context switch and, hence, possibly better interrupt
+   performance.  But, (2) since floating point registers are not saved,
+   you cannot use floating point operations within interrupt handlers.
+
+   This logic can be enabled by simply adding the following to your .config
+   file:
+
+   CONFIG_ARCH_FPU=y
+
+2. Non-Lazy Floating Point Register Save
+
+   Mike Smith has contributed an extensive re-write of the ARMv7-M exception
+   handling logic. This includes verified support for the FPU.  These changes
+   have not yet been incorporated into the mainline and are still considered
+   experimental.  These FPU logic can be enabled with:
+
+   CONFIG_ARCH_FPU=y
+   CONFIG_ARMV7M_CMNVECTOR=y
+
+   You will probably also changes to the ld.script in if this option is selected.
+   This should work:
+
+   -ENTRY(_stext)
+   +ENTRY(__start)         /* Treat __start as the anchor for dead code stripping */
+   +EXTERN(_vectors)       /* Force the vectors to be included in the output */
+
+CFLAGS
+------
+
+Only the Atollic toolchain has built-in support for the Cortex-M4 FPU.  You will see
+the following lines in each Make.defs file:
+
+  ifeq ($(CONFIG_LPC43_ATOLLIC_LITE),y)
+    # Atollic toolchain under Windows
+    ...
+  ifeq ($(CONFIG_ARCH_FPU),y)
+    ARCHCPUFLAGS = -mcpu=cortex-m4 -mthumb -march=armv7e-m -mfpu=fpv4-sp-d16 -mfloat-abi=hard
+  else
+    ARCHCPUFLAGS = -mcpu=cortex-m3 -mthumb -mfloat-abi=soft
+  endif
+  endif
+
+If you are using a toolchain other than the Atollic toolchain, then to use the FPU
+you will also have to modify the CFLAGS to enable compiler support for the ARMv7-M
+FPU.  As of this writing, there are not many GCC toolchains that will support the
+ARMv7-M FPU.
+
+As a minimum you will need to add CFLAG options to (1) enable hardware floating point
+code generation, and to (2) select the FPU implementation.  You might try the same
+options as used with the Atollic toolchain in the Make.defs file:
+
+  ARCHCPUFLAGS = -mcpu=cortex-m4 -mthumb -march=armv7e-m -mfpu=fpv4-sp-d16 -mfloat-abi=hard
+
+Configuration Changes
+---------------------
+
+Below are all of the configuration changes that I had to make to configs/stm3240g-eval/nsh2
+in order to successfully build NuttX using the Atollic toolchain WITH FPU support:
+
+  -CONFIG_ARCH_FPU=n              : Enable FPU support
+  +CONFIG_ARCH_FPU=y
+
+  -CONFIG_LPC43_CODESOURCERYW=y   : Disable the CodeSourcery toolchain
+  +CONFIG_LPC43_CODESOURCERYW=n
+
+  -CONFIG_LPC43_ATOLLIC_LITE=n    : Enable *one* the Atollic toolchains
+   CONFIG_LPC43_ATOLLIC_PRO=n
+  -CONFIG_LPC43_ATOLLIC_LITE=y    : The "Lite" version, OR
+   CONFIG_LPC43_ATOLLIC_PRO=y     : The "Pro" version (not both)
+
+  -CONFIG_INTELHEX_BINARY=y       : Suppress generation FLASH download formats
+  +CONFIG_INTELHEX_BINARY=n       : (Only necessary with the "Lite" version)
+
+  -CONFIG_HAVE_CXX=y              : Suppress generation of C++ code
+  +CONFIG_HAVE_CXX=n              : (Only necessary with the "Lite" version)
+
+See the section above on Toolchains, NOTE 2, for explanations for some of
+the configuration settings.  Some of the usual settings are just not supported
+by the "Lite" version of the Atollic toolchain.
+
+LPC4330-Xplorer Configuration Options
+=====================================
+

+
+       CONFIG_DRAM_SIZE=(32*1024) (32Kb)
+
+       There is an additional 32Kb of SRAM in AHB SRAM banks 0 and 1.
+
+    CONFIG_DRAM_START - The start address of installed DRAM
+
+       CONFIG_DRAM_START=0x10000000
+
+    CONFIG_ARCH_IRQPRIO - The LPC43xx supports interrupt prioritization

+       CONFIG_ARCH_IRQPRIO=y
+
+    CONFIG_ARCH_FPU - The LPC43xxx supports a floating point unit (FPU)
+
+       CONFIG_ARCH_FPU=y
+ 
+    CONFIG_BOOT_xxx - The startup code needs to know if the code is running
+       from internal FLASH, external FLASH, SPIFI, or SRAM in order to
+       initialize properly.  Note that a boot device is not specified for 
+       cases where the code is copied into SRAM; those cases are all covered
+       by CONFIG_BOOT_SRAM.
+
+       CONFIG_BOOT_SRAM=y      : Running from SRAM             (0x1000:0000)

+      used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.

+
+Configurations
+==============
+
+Each LPC4330-Xplorer configuration is maintained in a sudirectory and can be selected
+as follow:
+
+    cd tools
+    ./configure.sh lpc4330-xplorer/<subdir>
+    cd -
+    . ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  ostest:
+  ------
+    This configuration of this directory performs a simple OS test using
+    examples/ostest.  By default, this project assumes that you are
+    executing directly from SRAM.
+
+      CONFIG_BOOT_SRAM=y             : Executing in SRAM
+      CONFIG_LPC43_CODEREDW=y        : Code Red under Windows
+
+    This configuration directory, performs a simple test of the USB host
+    HID keyboard class driver using the test logic in examples/hidkbd.
+
+    If you use the Atollic toolchain, then the FPU test can be enabled in the
+    examples/ostest by adding the following your NuttX configuration file:
+
+     -CONFIG_ARCH_FPU=n              : Enable FPU support
+     +CONFIG_ARCH_FPU=y
+
+     -CONFIG_LPC43_CODESOURCERYW=y   : Disable the CodeSourcery toolchain
+     +CONFIG_LPC43_CODESOURCERYW=n
+
+     -CONFIG_LPC43_ATOLLIC_LITE=n    : Enable *one* the Atollic toolchains
+      CONFIG_LPC43_ATOLLIC_PRO=n
+     -CONFIG_LPC43_ATOLLIC_LITE=y    : The "Lite" version, OR
+      CONFIG_LPC43_ATOLLIC_PRO=n     : The "Pro" version (only one)
+
+     -CONFIG_INTELHEX_BINARY=y       : Suppress generation FLASH download formats
+     +CONFIG_INTELHEX_BINARY=n       : (Only necessary with the "Lite" version)
+
+     -CONFIG_HAVE_CXX=y              : Suppress generation of C++ code
+     +CONFIG_HAVE_CXX=n              : (Only necessary with the "Lite" version)
+
+     -CONFIG_SCHED_WAITPID=y         : Enable the waitpid() API needed by the FPU test
+     +CONFIG_SCHED_WAITPID=n
+
+    The FPU test also needs to know the size of the FPU registers save area in
+    bytes (see arch/arm/include/armv7-m/irq_lazyfpu.h):
+
+     +CONFIG_EXAMPLES_OSTEST_FPUSIZE=(4*33)
+
+  nsh:
+  ----
+    This configuration is the NuttShell (NSH) example at examples/nsh/
+    examples/ostest.    By default, this project assumes that you are
+    executing directly from SRAM.
+
+      CONFIG_BOOT_SRAM=y             : Executing in SRAM
+      CONFIG_LPC43_CODEREDW=y        : Code Red under Windows
+
+    To execute from SPIFI, you would need to set:
+
+      CONFIG_BOOT_SPIFI=y            : Executing from SPIFI
+      CONFIG_DRAM_SIZE=(128*1024)    : SRAM Bank0 size
+      CONFIG_DRAM_START=0x10000000   : SRAM Bank0 base address
+      CONFIG_SPIFI_OFFSET=(512*1024) : SPIFI file system offset
+
+    CONFIG_MM_REGIONS should also be increased if you want to other SRAM banks
+    to the memory pool.
+
+    This configuration has some special options that can be used to
+    create a block device on the SPIFI FLASH.  NOTE:  CONFIG_LPC43_SPIFI=y
+    must also be defined to enable SPIFI setup support:
+
+    SPIFI device geometry:
+
+      CONFIG_SPIFI_OFFSET - Offset the beginning of the block driver this many
+        bytes into the device address space.  This offset must be an exact
+        multiple of the erase block size (CONFIG_SPIFI_BLKSIZE). Default 0.
+      CONFIG_SPIFI_BLKSIZE - The size of one device erase block.  If not defined
+        then the driver will try to determine the correct erase block size by
+        examining that data returned from spifi_initialize (which sometimes
+        seems bad).
+
+    Other SPIFI options
+
+      CONFIG_SPIFI_SECTOR512 - If defined, then the driver will report a more
+        FAT friendly 512 byte sector size and will manage the read-modify-write
+        operations on the larger erase block.
+      CONFIG_SPIFI_READONLY - Define to support only read-only operations.
+      CONFIG_SPIFI_LIBRARY - Don't use the LPC43xx ROM routines but, instead,
+        use an external library implementation of the SPIFI interface.
+      CONFIG_SPIFI_VERIFY - Verify all spifi_program() operations by reading
+        from the SPI address space after each write.
+      CONFIG_DEBUG_SPIFI_DUMP - Debug option to dump read/write buffers.  You
+        probably do not want to enable this unless you want to dig through a
+        *lot* of debug output!  Also required CONFIG_DEBUG, CONFIG_DEBUG_VERBOSE,
+        and CONFIG_DEBUG_FS,
+
+    In my experience, there were some missing function pointers in the LPC43xx
+    SPIFI ROM routines and the SPIFI configuration could only be built with
+    CONFIG_SPIFI_LIBRARY=y.  The SPIFI library is proprietary and cannot be
+    provided within NuttX open source repository; SPIFI library binaries can
+    be found on the lpcware.com website.  In this build sceneario, you must
+    also provide the patch to the external SPIFI library be defining the make
+    variable EXTRA_LIBS in the top-level Make.defs file.  Good luck!

+Jumpers
+-------
+
+  There are many jumpers on the base board.  A usable combination is the
+  default jumper settings WITH the two J54 jumpers both removed.  Those
+  jumpers are for ISP support and will cause the board to reset.
+
+  To use the SD, J55 must be set to provide chip select PIO1_11 signal as
+  the SD slot chip select.

+
+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The Code Red GNU toolchain
+  2. The CodeSourcery GNU toolchain,
+  3. The devkitARM GNU toolchain,
+  4. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the Code Red toolchain and the
+  make system is setup to default to use the Code Red Linux toolchain.  To use
+  the other toolchain, you simply need add one of the following configuration
+  options to your .config (or defconfig) file:
+
+    CONFIG_LPC17_CODESOURCERYW=y   : CodeSourcery under Windows
+    CONFIG_LPC17_CODESOURCERYL=y   : CodeSourcery under Linux
+    CONFIG_LPC17_DEVKITARM=y       : devkitARM under Windows
+    CONFIG_LPC17_BUILDROOT=y       : NuttX buildroot under Linux or Cygwin (default)
+    CONFIG_LPC17_CODEREDW=n        : Code Red toolchain under Windows
+    CONFIG_LPC17_CODEREDL=y        : Code Red toolchain under Linux
+
+  You may also have to modify the PATH in the setenv.h file if your make cannot
+  find the tools.
+
+  NOTE: the CodeSourcery (for Windows), devkitARM, and Code Red (for Windoes)
+  are Windows native toolchains.  The CodeSourcey (for Linux), Code Red (for Linux)
+  and NuttX buildroot toolchains are Cygwin and/or Linux native toolchains. There
+  are several limitations to using a Windows based toolchain in a Cygwin
+  environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+Code Red IDE
+^^^^^^^^^^^^
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project.
+  
+  Makefile Build
+  --------------
+  Under Linux Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/lpc17xx,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/lpc17x/lpc17_vectors.S.
+
+  Using Code Red GNU Tools from Cygwin
+  ------------------------------------
+
+  Under Cygwin, the Code Red command line tools (e.g., arm-non-eabi-gcc) cannot
+  be executed because the they only have execut privileges for Administrators.  I
+  worked around this by:
+  
+  Opening a native Cygwin RXVT as Administrator (Right click, "Run as administrator"),
+  then executing 'chmod 755 *.exe' in the following directories:
+
+  /cygdrive/c/nxp/lpcxpreeso_3.6/bin, and
+  /cygdrive/c/nxp/lpcxpreeso_3.6/Tools/bin
+
+  Command Line Flash Programming
+  ------------------------------
+
+  If using LPCLink as your debug connection, first of all boot the LPC-Link using
+  the script:
+
+    bin\Scripts\bootLPCXpresso type
+
+  where type = winusb for Windows XP, or type = hid for Windows Vista / 7.
+
+  Now run the flash programming utility with the following options
+
+    flash_utility wire -ptarget -flash-load[-exec]=filename [-load-base=base_address]
+
+  Where flash_utility is one of:
+
+    crt_emu_lpc11_13 (for LPC11xx or LPC13xx parts)
+    crt_emu_cm3_nxp (for LPC17xx parts)
+    crt_emu_a7_nxp (for LPC21/22/23/24 parts)
+    crt_emu_a9_nxp (for LPC31/32 and LPC29xx parts)
+    crt_emu_cm3_lmi (for TI Stellaris LM3S parts
+
+  wire is one of:
+
+    (empty) (for Red Probe+, Red Probe, RDB1768v1, or TI Stellaris evaluation boards)
+    -wire=hid (for RDB1768v2 without upgraded firmware)
+    -wire=winusb (for RDB1768v2 with upgraded firmware)
+    -wire=winusb (for LPC-Link on Windows XP)
+    -wire=hid (for LPC-Link on Windows Vista/ Windows 7)
+
+  target is the target chip name. For example LPC1343, LPC1114/301, LPC1768 etc.
+
+  filename is the file to flash program. It may be an executable (axf) or a binary
+  (bin) file. If using a binary file, the base_address must be specified.
+
+  base_address is the base load address when flash programming a binary file. It
+  should be specified as a hex value with a leading 0x.
+
+  Note:
+  - flash-load will leave the processor in a stopped state
+  - flash-load-exec will start execution of application as soon as download has
+    completed.
+
+  Examples
+    To load the executable file app.axf and start it executing on an LPC1758
+    target using Red Probe, use the following command line:
+
+      crt_emu_cm3_nxp -pLPC1758 -flash-load-exec=app.axf
+
+    To load the binary file binary.bin to address 0x1000 to an LPC1343 target
+    using LPC-Link on Windows XP, use the following command line:
+
+      crt_emu_lpc11_13_nxp -wire=hid -pLPC1343 -flash-load=binary.bin -load-base=0x1000
+
+  tools/flash.sh
+  --------------
+
+  All of the above steps are automated in the bash script flash.sh that can
+  be found in the configs/lpcxpresso/tools directory.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/projects/nuttx/files/).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh lpcxpresso-lpc1768/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you
+  are building a Cortex-M3 toolchain for Cygwin under Windows.
+
+  NOTE: This is an OABI toolchain.
+
+NXFLAT Toolchain
+^^^^^^^^^^^^^^^^
+
+  If you are *not* using the NuttX buildroot toolchain and you want to use
+  the NXFLAT tools, then you will still have to build a portion of the buildroot
+  tools -- just the NXFLAT tools.  The buildroot with the NXFLAT tools can
+  be downloaded from the NuttX SourceForge download site
+  (https://sourceforge.net/projects/nuttx/files/).
+ 
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh lpcxpresso-lpc1768/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-nxflat .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly builtNXFLAT binaries.
+
+LEDs
+^^^^
+
+  If CONFIG_ARCH_LEDS is defined, then support for the LPCXpresso LEDs will be
+  included in the build.  See:
+
+  - configs/lpcxpresso-lpc1768/include/board.h - Defines LED constants, types and
+    prototypes the LED interface functions.
+
+  - configs/lpcxpresso-lpc1768/src/lpcxpresso_internal.h - GPIO settings for the LEDs.
+
+  - configs/lpcxpresso-lpc1768/src/up_leds.c - LED control logic.
+
+  The LPCXpresso LPC1768 has a single LEDs (there are more on the Embedded Artists
+  base board, but those are not controlled by NuttX).  Usage this single LED by NuttX
+  is as follows:
+
+  - The LED is not illuminated until the LPCXpresso completes initialization.
+  
+    If the LED is stuck in the OFF state, this means that the LPCXpresso did not 
+    complete intialization.
+
+  - Each time the OS enters an interrupt (or a signal) it will turn the LED OFF and
+    restores its previous stated upon return from the interrupt (or signal).
+
+    The normal state, after initialization will be a dull glow.  The brightness of
+    the glow will be inversely related to the proportion of time spent within interrupt
+    handling logic.  The glow may decrease in brightness when the system is very
+    busy handling device interrupts and increase in brightness as the system becomes
+    idle.
+
+    Stuck in the OFF state suggests that that the system never completed
+    initialization;  Stuck in the ON state would indicated that the system
+    intialialized, but is not takint interrupts.
+
+  - If a fatal assertion or a fatal unhandled exception occurs, the LED will flash
+    strongly as a slow, 2Hz rate.
+
+LPCXpresso Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  General Architecture Settings:
+
+    CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+     be set to:
+
+       CONFIG_ARCH=arm
+
+    CONFIG_ARCH_family - For use in C code:
+
+       CONFIG_ARCH_ARM=y
+
+    CONFIG_ARCH_architecture - For use in C code:
+
+       CONFIG_ARCH_CORTEXM3=y
+
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+       CONFIG_ARCH_CHIP=lpc17xx
+
+    CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+       chip:
+
+       CONFIG_ARCH_CHIP_LPC1768=y
+
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+
+       CONFIG_ARCH_BOARD=lpcxpresso-lpc1768
+
+    CONFIG_ARCH_BOARD_name - For use in C code
+
+       CONFIG_ARCH_BOARD_LPCEXPRESSO=y
+
+    CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+       of delay loops
+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_DRAM_SIZE - Describes the installed DRAM (CPU SRAM in this case):
+
+       CONFIG_DRAM_SIZE=(32*1024) (32Kb)
+
+       There is an additional 32Kb of SRAM in AHB SRAM banks 0 and 1.
+
+    CONFIG_DRAM_START - The start address of installed DRAM
+
+       CONFIG_DRAM_START=0x10000000
+
+    CONFIG_ARCH_IRQPRIO - The LPC17xx supports interrupt prioritization
+
+       CONFIG_ARCH_IRQPRIO=y
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+       stack. If defined, this symbol is the size of the interrupt
+       stack in bytes.  If not defined, the user task stacks will be
+       used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.

+
+Configurations
+^^^^^^^^^^^^^^
+
+Each LPCXpresso configuration is maintained in a sudirectory and can be
+selected as follow:
+
+    cd tools
+    ./configure.sh lpcxpresso-lpc1768/<subdir>
+    cd -
+    . ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  dhcpd:
+    This builds the DCHP server using the apps/examples/dhcpd application
+    (for execution from FLASH.) See apps/examples/README.txt for information
+    about the dhcpd example.
+
+    Jumpers: Nothing special.  Use the default base board jumper
+    settings.
+
+  nsh:
+    Configures the NuttShell (nsh) located at apps/examples/nsh.  The
+    Configuration enables both the serial and telnet NSH interfaces.
+    Support for the board's SPI-based MicroSD card is included
+    (but not passing tests as of this writing).
+
+    NOTE: At present, the value for the SD SPI frequency is too
+    high and the SD will fail.  Setting that frequency to 400000
+    removes the problem. TODO:  Tune this frequency to some optimal
+    value.
+
+    Jumpers: J55 must be set to provide chip select PIO1_11 signal as
+    the SD slot chip select.
+
+  nx:
+    And example using the NuttX graphics system (NX).  This example
+    uses the UG-9664HSWAG01 driver.
+
+    Jumpers:  There are several jumper settings needed by the OLED.
+    All are the default settings:
+    
+    J42: Close to select the SPI interface (Default: closed)
+    J43: Close to support OLED command/data select (Default: closed)
+    J44: Close to allow control of OLED voltage (Default: closed)
+    J45: Close to select SPI clock (Default: closed)
+    J46: Close SPI data input (MOSI) (Default:closed)
+
+  ostest:
+    This configuration directory, performs a simple OS test using
+    apps/examples/ostest.
+ 
+    Jumpers: Nothing special.  Use the default base board jumper
+    settings.
+
+  thttpd:
+    This builds the THTTPD web server example using the THTTPD and
+    the apps/examples/thttpd application.
+
+    NOTE:  You will need to build the NXFLAT toolchain as described
+    above in order to use this example.
+
+    Jumpers: Nothing special.  Use the default base board jumper
+    settings.
+
+  usbstorage:
+    This configuration directory exercises the USB mass storage
+    class driver at apps/examples/usbstorage.  See apps/examples/README.txt
+    for more information.
+
+    NOTE: At present, the value for the SD SPI frequency is too
+    high and the SD will fail.  Setting that frequency to 400000
+    removes the problem. TODO:  Tune this frequency to some optimal
+    value.
+ 
+    Jumpers: J55 must be set to provide chip select PIO1_11 signal as
+    the SD slot chip select.

+
+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery or devkitARM toolchain, you simply need add one of the
+  following configuration options to your .config (or defconfig) file:
+
+    CONFIG_LPC17_CODESOURCERYW=y   : CodeSourcery under Windows
+    CONFIG_LPC17_CODESOURCERYL=y   : CodeSourcery under Linux
+    CONFIG_LPC17_DEVKITARM=y       : devkitARM under Windows
+    CONFIG_LPC17_BUILDROOT=y       : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_LPC17_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows)and devkitARM are Windows native toolchains.
+  The CodeSourcey (for Linux) and NuttX buildroot toolchains are Cygwin and/or
+  Linux native toolchains. There are several limitations to using a Windows based
+  toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+^^^^
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project (There is a simple RIDE project
+  in the RIDE subdirectory).
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/lpc17xx,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/lpc17x/lpc17_vectors.S.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh mbed/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you
+  are building a Cortex-M3 toolchain for Cygwin under Windows.
+
+  NOTE: This is an OABI toolchain.
+
+mbed Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+	   be set to:
+
+	   CONFIG_ARCH=arm
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_ARM=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_CORTEXM3=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=lpc17xx
+
+	CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+	   chip:
+
+	   CONFIG_ARCH_CHIP_LPC1768=y
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=mbed (for the mbed.org board)
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_MBED=y
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - Describes the installed DRAM (CPU SRAM in this case):
+
+	   CONFIG_DRAM_SIZE=(32*1024) (32Kb)
+
+	   There is an additional 32Kb of SRAM in AHB SRAM banks 0 and 1.
+
+	CONFIG_DRAM_START - The start address of installed DRAM
+
+	   CONFIG_DRAM_START=0x10000000
+
+	CONFIG_ARCH_IRQPRIO - The LPC17xx supports interrupt prioritization
+
+	   CONFIG_ARCH_IRQPRIO=y
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	    stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.
+
+	Individual subsystems can be enabled:
+	  CONFIG_LPC17_MAINOSC=y

+	  CONFIG_LPC17_TMR0=n
+	  CONFIG_LPC17_TMR1=n
+	  CONFIG_LPC17_TMR2=n
+	  CONFIG_LPC17_TMR3=n
+	  CONFIG_LPC17_RIT=n

+
+USB Host Configuration
+^^^^^^^^^^^^^^^^^^^^^^
+
+The mbed board can be easily modified to support a USB host interface
+(Remember to add 2 resistors of 15K to D+ and D- pins).  The hidkbd
+configuration assumes that this change has been made.
+
+The NuttShell (NSH) mbed can also be modified in order to support USB
+host operations.  To make these modifications, do the following:
+
+1. First configure to build the NSH configuration from the top-level
+   NuttX directory:
+
+   cd tools
+   ./configure mbed/nsh
+   cd ..
+
+2. Then edit the top-level .config file to enable USB host.  Make the
+   following changes:
+
+   CONFIG_LPC17_USBHOST=n
+   CONFIG_USBHOST=n
+   CONFIG_SCHED_WORKQUEUE=y
+
+When this change is made, NSH should be extended to support USB flash
+devices.  When a FLASH device is inserted, you should see a device
+appear in the /dev (pseudo) directory.  The device name should be
+like /dev/sda, /dev/sdb, etc.  The USB mass storage device, is present
+it can be mounted from the NSH command line like:
+
+   ls /dev
+   mount -t vfat /dev/sda /mnt/flash
+
+Files on the connect USB flash device should then be accessible under
+the mountpoint /mnt/flash.
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each mbed configuration is maintained in a sudirectory and can be selected
+as follow:
+
+	cd tools
+	./configure.sh mbed/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  hidkbd:
+    This configuration directory, performs a simple test of the USB host
+    HID keyboard class driver using the test logic in examples/hidkbd.
+    This configuration assumes that you have modified your mbed for USB
+    host support.
+
+  nsh:
+    Configures the NuttShell (nsh) located at examples/nsh.  The
+    Configuration enables only the serial NSH interfaces.  See notes
+    above for enabling USB host support in this configuration.

+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The NuttX buildroot Toolchain (see below).
+  2. The CodeSourcery GNU toolchain,
+  3. The devkitARM GNU toolchain, or
+ 
+  All testing has been conducted using the NuttX buildroot toolchain.  To use
+  the CodeSourcery or devkitARM GNU toolchain, you simply need to build the
+  system as follows:
+
+     make                         # Will build for the NuttX buildroot toolchain
+     make CROSSDEV=arm-eabi-      # Will build for the devkitARM toolchain
+     make CROSSDEV=arm-none-eabi- # Will build for the CodeSourcery toolchain
+     make CROSSDEV=arm-elf-       # Will build for the NuttX buildroot toolchain
+
+  Of course, hard coding this CROSS_COMPILE value in Make.defs file will save
+  some repetitive typing.
+
+  NOTE: the CodeSourcery and devkitARM toolchains are Windows native toolchains.
+  The NuttX buildroot toolchain is a Cygwin toolchain.  There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context; make CROSSDEV=arm-none-eabi-
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the CodeSourcery toolchain.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) may not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh eagle100/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you are
+  building a Cortex-M3 toolchain for Cygwin under Windows.
+
+Flash Tools
+^^^^^^^^^^^
+
+In System Programming (ISP) Mode
+--------------------------------
+
+1. Make sure you exit minicom (or whatever terminal emulator you are
+   using).  It will interfere with the download.
+
+2. On the MCU123 board, I need to put a jumper on JP3-INT. On that board,
+   JP3-INT is connected to P0.14 of LPC214x. When P0.14 is low and RTS is
+   changed from high to low, the LPC214x will enter ISP (In System
+   Programming) state.
+
+   J2-RST: When J2 is shorted, the reset pin of CPU is controlled by
+   the DTR signal of UART0. Short J2 to enable ISP automatic download.
+
+   Alternatively, you can just press the INT1 button while resetting.
+   The LEDs will be off if the LPC2148 successfully enters ISP mode.
+
+Resetting the board will enter ISP mode when the jumper is connected.
+
+LPC21ISP (Linux)
+----------------
+
+(ca. 2008)
+I use the lpc21isp tool to load NuttX into FLASH.  That tool is available
+in the files section at http://tech.groups.yahoo.com/group/lpc21isp/.  In
+the older version 1.60 of lpc21isp for Linux, I had to make several changes.
+This changes are shown in lpc21ips-1.60.diff.
+
+I use the script lpc21isp.sh to perform the actual download.  You will
+probably have to make some changes to this script in order to use it.
+For example, the path to the built lpc21isp binary will most likely
+have to change.  Then move this script to the top level NuttX
+directory and simply execute it to load NuttX onto the board (after
+entering ISP mode).
+
+Here are the detailed steps I use:
+
+1. Setup ISP (In System Programming) mode (see above).
+
+3. Start lpc21isp.sh
+
+4. Reset the board to 
+
+FlashMagic (Windows/MAC)
+------------------------
+
+(ca. 2012)
+You download FlashMagic for Windows or MAC here: http://www.flashmagictool.com
+
+1. Setup ISP (In System Programming) mode (see above).
+
+2. Start FlashMagic and setup communication parameters.
+
+   Device:           LPC2148
+   COM Port:         (will vary with PC)
+   Baud:             38400 (I am sure it can go faster).
+   Interface:        None (ISP)
+   Oscillator (MHz): 12
+
+   Check "Erase all Flash+Code Rd Prot"
+
+3. Select the nuttx.hex file
+
+4. Options: Verify after programming
+
+5. Start and reset the board to entry ISP mode.  Or hold the INT1
+   button down after reset after you press start.
+
+NOTE:  FlashMagic will complain if the data section overlaps 
+       0x4000000-0x400001ff.
+
+OpenOCD
+-------
+
+I have the (really old) Olimex software installed at C:/gccfd.  Under
+Cygwin, I can do the following:
+
+1. Create a .cfg file:
+
+   $ cat /cygdrive/c/gccfd/openocd/lib/openocd/interface/arm-usb-ocd.cfg /cygdrive/c/gccfd/openocd/lib/openocd/target/lpc2148.cfg > lpc2148.cfg 
+
+2. Start OpenOCD:
+
+   /cygdrive/c/gccfd/openocd/bin/openocd-ftd2xx.exe -f lpc2148.cfg -s . &
+
+3. Start arm-*-gdb (whichever GDB your toolchain uses).
+   
+ARM/LPC214X-specific Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+	   be set to:
+
+	   CONFIG_ARCH=arm
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_ARM=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_ARM7TDMI=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=lpc214x
+
+	CONFIG_ARCH_CHIP_name - For use in C code
+
+	   CONFIG_ARCH_CHIP_LPC214X
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=mcu123-lpc214x
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_MCU123 (for the Spectrum Digital C5471 EVM)
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - Describes the installed RAM.
+
+	CONFIG_DRAM_START - The start address of installed RAM
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	   stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.
+
+  LPC2148 specific chip initialization
+
+    These provide register setup values:
+	CONFIG_EXTMEM_MODE, CONFIG_RAM_MODE, CONFIG_CODE_BASE, CONFIG_PLL_SETUP,
+	CONFIG_MAM_SETUP, CONFIG_APBDIV_SETUP, CONFIG_EMC_SETUP, CONFIG_BCFG0_SETUP,
+	CONFIG_BCFG1_SETUP, CONFIG_BCFG2_SETUP, CONFIG_BCFG3_SETUP, CONFIG_ADC_SETUP
+
+	CONFIG_LPC214x_FIO - Enable fast GPIO (vs. legacy, "old" GPIO).
+
+  LPC214X specific device driver settings
+
+	CONFIG_UARTn_SERIAL_CONSOLE - selects the UARTn for the
+	   console and ttys0 (default is the UART0).
+
+	CONFIG_UARTn_RXBUFSIZE - Characters are buffered as received.
+	   This specific the size of the receive buffer
+
+	CONFIG_UARTn_TXBUFSIZE - Characters are buffered before
+	   being sent.  This specific the size of the transmit buffer
+
+	CONFIG_UARTn_BAUD - The configure BAUD of the UART.
+
+	CONFIG_UARTn_BITS - The number of bits.  Must be either 7 or 8.
+
+	CONFIG_UARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity, 3=mark 1, 4=space 0
+
+	CONFIG_UARTn_2STOP - Two stop bits
+
+  LPC214X USB Configuration
+
+	CONFIG_LPC214X_USBDEV_FRAME_INTERRUPT
+	   Handle USB Start-Of-Frame events. 
+	   Enable reading SOF from interrupt handler vs. simply reading on demand.
+	   Probably a bad idea... Unless there is some issue with sampling the SOF
+	   from hardware asynchronously.
+
+	CONFIG_LPC214X_USBDEV_EPFAST_INTERRUPT
+	   Enable high priority interrupts.  I have no idea why you might want to
+	   do that
+
+	CONFIG_LPC214X_USBDEV_NDMADESCRIPTORS
+	   Number of DMA descriptors to allocate in the 8Kb USB RAM.  This is a
+	   tradeoff between the number of DMA channels that can be supported vs
+	   the size of the DMA buffers available.
+
+	CONFIG_LPC214X_USBDEV_DMA
+	   Enable lpc214x-specific DMA support
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each NXP LPC214x configuration is maintained in a sudirectory and
+can be selected as follow:
+
+	cd tools
+	./configure.sh mcu123-lpc214x/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+composite:
+----------
+
+  A simple test of the USB Composite Device (see
+  apps/examples/README.txt and apps/examples/composite)
+
+  Default toolchain:  CodeSourcery for Windows
+  Output format:  ELF and Intel HEX
+
+  NOTE:  I could not get this to work!  Perhaps this is a
+  consequence of the last USB driver checking (r4359). But
+  backing this change out did not fix the configuration.
+
+nsh:
+----
+
+  Configures the NuttShell (nsh) located at examples/nsh.  The
+  Configuration enables only the serial NSH interfaces.
+
+  Default toolchain:  Buildroot

+
+ostest:
+-------
+
+  This configuration directory, performs a simple OS test using
+  examples/ostest.
+
+  Default toolchain:  Buildroot

+----------
+
+  This configuration directory exercises the USB serial class
+  driver at examples/usbserial.  See examples/README.txt for
+  more information.
+
+  Default toolchain:  Buildroot
+  Output format:  ELF and binary
+
+  NOTE:  If you have problems with this configurationt, perhaps it is a
+  consequence of the last USB driver checking (r4359)
+
+usbstorage:
+-----------
+
+  This configuration directory exercises the USB mass storage
+  class driver at examples/usbstorage.  See examples/README.txt for

+README
+^^^^^
+
+This is the README file for the port of NuttX to the Micropendous 3 board.
+This board is develepmend by http://code.google.com/p/opendous/.  The
+Micropendous 3 is based on an Atmel AT90USB646, 647, 1286 or 1287 MCU.
+NuttX was ported using the AT90USB647 version.  As of this writing,
+documentation for the Micropendous board is available here:
+http://code.google.com/p/micropendous/wiki/Micropendous3

+DFU Bootloader
+^^^^^^^^^^^^^^
+
+There is also an DFU bootloader that resides in the upper 8Kb of FLASH
+(unless you ERASE the flash with with ICE).  You can enter this bootloader
+(if it is in FLASH) by:
+
+Holding both the SW1 (RESET) and SW2, then releasing SW1 while continuing
+to hold SW2.  SW2 connects to the PE2/HWB signal and causes a reset into
+the bootloader memory region.
+
+Then you can use FLIP to load code into FLASH (available at the Atmel Web
+Site).  The DFU USB driver for the DFU bootload is available in the usb
+subdirectory in the FLIP installation location.
+
+Serial Console
+^^^^^^^^^^^^^^
+
+  A serial console is supported on an external MAX232/MAX3232 Connected
+  on PD2 and PD3:
+
+  Port D, Bit 2: RXD1, Receive Data (Data input pin for the USART1). When
+    the USART1 receiver is enabled this pin is configured as an input
+    regardless of the value of DDD2. When the USART forces this pin to
+    be an input, the pull-up can still be controlled by the PORTD2 bit.
+  Port D, Bit 3: TXD1, Transmit Data (Data output pin for the USART1).
+    When the USART1 Transmitter is enabled, this pin is configured as
+    an output regardless of the value of DDD3.

+There are several toolchain options.  However, testing has been performed
+using *only* the NuttX buildroot toolchain described below.  Therefore,
+the NuttX buildroot toolchain is the recommended choice:
+
+Buildroot:
+
+  There is a DIY buildroot version for the AVR boards here:
+  http://sourceforge.net/projects/nuttx/files/buildroot/.  See the
+  following section for details on building this toolchain.
+
+  It is assumed in some places that buildroot toolchain is available
+  at ../misc/buildroot/build_avr.  Edit the setenv.sh file if
+  this is not the case.
+
+  After configuring NuttX, make sure that CONFIG_AVR_BUILDROOT=y is set in your
+  .config file.
+
+WinAVR:
+
+  For Cygwin development environment on Windows machines, you can use
+  WinAVR: http://sourceforge.net/projects/winavr/files/
+
+  It is assumed in some places that WinAVR is installed at C:/WinAVR.  Edit the
+  setenv.sh file if this is not the case.
+
+  After configuring NuttX, make sure that CONFIG_AVR_WINAVR=y is set in your
+  .config file.
+
+  WARNING:  There is an incompatible version of cygwin.dll in the WinAVR/bin
+  directory!  Make sure that the path to the correct cygwin.dll file precedes
+  the path to the WinAVR binaries!
+
+Linux:
+
+  For Linux, there are widely available avr-gcc packages.  On Ubuntu, use:
+  sudo apt-get install gcc-avr gdb-avr avr-libc
+
+  After configuring NuttX, make sure that CONFIG_AVR_LINUXGCC=y is set in your
+  .config file.
+
+Windows Native Toolchains
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  The WinAVR toolchain is a Windows native toolchain. There are several
+  limitations to using a Windows native toolchain in a Cygwin environment. 
+  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath'
+     utility but you might easily find some new path problems.  If so, check
+     out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic
+     links are used in Nuttx (e.g., include/arch).  The make system works
+     around these  problems for the Windows tools by copying directories
+     instead of linking them.  But this can also cause some confusion for
+     you:  For example, you may edit a file in a "linked" directory and find
+     that your changes had no effect. That is because you are building the
+     copy of the file in the "fake" symbolic directory.  If you use a
+     Windows toolchain, you should get in the habit of making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This
+     is because the dependencies are generated using Windows pathes which do
+     not work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native
+     toolchains.  That support can be enabled by modifying your Make.defs
+     file as follows:
+
+    -  MKDEP = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are
+     not building on C:), then you may need to modify tools/mkdeps.sh
+
+  An additional issue with the WinAVR toolchain, in particular, is that it
+  contains an incompatible version of the Cygwin DLL in its bin/ directory.
+  You must take care that the correct Cygwin DLL is used.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  If NuttX buildroot toolchain source tarball cne can be downloaded from the
+  NuttX SourceForge download site (https://sourceforge.net/projects/nuttx/files/).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh micropendous3/<sub-dir>
+
+     NOTE: you also must copy avr-libc header files into the NuttX include
+     directory with command perhaps like:
+
+     cp -a /cygdrive/c/WinAVR/include/avr include/.
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/avr-defconfig-4.5.2 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you
+  are building a toolchain for Cygwin under Windows.
+
+avr-libc
+^^^^^^^^
+
+Header Files
+
+  In any case, header files from avr-libc are required:  http://www.nongnu.org/avr-libc/.
+  A snapshot of avr-lib is included in the WinAVR installation. For Linux
+  development platforms, avr-libc package is readily available (and would
+  be installed in the apt-get command shown above).  But if you are using
+  the NuttX buildroot configuration on Cygwin, then you will have to build
+  get avr-libc from binaries.
+
+Header File Installation
+
+  The NuttX build will required that the AVR header files be available via
+  the NuttX include directory.  This can be accomplished by either copying
+  the avr-libc header files into the NuttX include directory:
+
+  cp -a <avr-libc-path>/include/avr <nuttx-path>/include/.
+
+  Or simply using a symbolic link:
+
+  ln -s <avr-libc-path>/include/avr <nuttx-path>/include/.
+
+Build Notes:
+
+  It may not necessary to have a built version of avr-lib; only header files
+  are required.  Bu if you choose to use the optimized libraru functions of
+  the flowing point library, then you may have to build avr-lib from sources.
+  Below are instructions for building avr-lib from fresh sources:
+
+  1. Download the avr-libc package from: 
+
+     http://savannah.nongnu.org/projects/avr-libc/
+
+     I am using avr-lib-1.7.1.tar.bz2
+
+  2. Upack the tarball and cd into the 
+ 
+     tar jxf avr-lib-1.7.1.tar.bz2
+     cd avr-lib-1.7.1
+
+  3. Configure avr-lib.  Assuming that WinAVR is installed at the following
+     location:
+
+     export PATH=/cygdrive/c/WinAVR/bin:$PATH
+     ./configure --build=`./config.guess` --host=avr
+
+     This takes a *long* time.
+
+  4. Make avr-lib.
+
+     make
+
+     This also takes a long time because it generates variants for nearly
+     all AVR chips.
+
+  5. Install avr-lib.
+
+     make install
+
+Micropendous3 Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+    CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+       be set to:
+
+       CONFIG_ARCH=avr
+
+    CONFIG_ARCH_family - For use in C code:
+
+       CONFIG_ARCH_AVR=y
+
+    CONFIG_ARCH_architecture - For use in C code:
+
+       CONFIG_ARCH_AT90USB=y
+
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+       CONFIG_ARCH_CHIP=at90usb
+
+    CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+       chip.  This should be exactly one of
+
+       CONFIG_ARCH_CHIP_AT90USB646=y
+       CONFIG_ARCH_CHIP_AT90USB647=y
+       CONFIG_ARCH_CHIP_AT90USB1286=y
+       CONFIG_ARCH_CHIP_AT90USB1287=y
+
+       Depending on which Micropendous3 version you have.
+
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+
+       CONFIG_ARCH_BOARD=micropendous3
+
+    CONFIG_ARCH_BOARD_name - For use in C code
+
+       CONFIG_ARCH_BOARD_MICROPENOUS3=y
+
+    CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+       of delay loops
+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_DRAM_SIZE - Describes the installed DRAM.  One of:
+
+       CONFIG_DRAM_SIZE=(4*1024) - (4Kb)
+       CONFIG_DRAM_SIZE=(8*1024) - (8Kb)
+
+    CONFIG_DRAM_START - The start address of installed SRAM
+
+       CONFIG_DRAM_START=0x800100
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+       stack. If defined, this symbol is the size of the interrupt
+       stack in bytes.  If not defined, the user task stacks will be
+      used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.
+
+    Individual subsystems can be enabled:

+      CONFIG_AVR_USART1=y
+      CONFIG_AVR_ANACOMP=n
+      CONFIG_AVR_ADC=n
+      CONFIG_AVR_TWI=n

+be selected as follow:
+
+    cd tools
+    ./configure.sh micropendous3/<subdir>
+    cd -

+    CONFIG_PIC32MX_MICROCHIPW      - MicroChip full toolchain for Windows (C32)
+    CONFIG_PIC32MX_MICROCHIPL      - MicroChip full toolchain for Linux (C32)
+    CONFIG_PIC32MX_MICROCHIPW_LITE - MicroChip LITE toolchain for Windows (C32)
+    CONFIG_PIC32MX_MICROCHIPL_LITE - MicroChip LITE toolchain for Linux (C32)
+
+  NOTE:  The "Lite" versions of the toolchain does not support C++.  Also
+  certain optimization levels are not supported by the Lite toolchain.
+
+  MicrochipOpen
+  -------------
+
+  An alternative, build-it-yourself toolchain is available here:
+  http://sourceforge.net/projects/microchipopen/ .  These tools were
+  last updated circa 2010.  NOTE:  C++ support still not available
+  in this toolchain.  Use this configuration option to select the microchipopen
+  toolchain:
+
+    CONFIG_PIC32MX_MICROCHIPOPENL - microchipOpen toolchain for Linux
+
+  And set the path appropriately in the setenv.sh file.
+
+  Building MicrochipOpen (on Linux)
+  ---------------------------------
+
+  1) Get the build script from this location:
+
+      http://microchipopen.svn.sourceforge.net/viewvc/microchipopen/ccompiler4pic32/buildscripts/trunk/
+
+  2) Build the code using the build script, for example:
+
+      ./build.sh -b v105_freeze
+
+     This will check out the selected branch and build the tools.
+
+  3) Binaries will then be available in a subdirectory with a name something like
+     pic32-v105-freeze-20120622/install-image/bin (depending on the current data
+     and the branch that you selected.
+
+     Note that the tools will have the prefix, mypic32- so, for example, the
+     compiler will be called mypic32-gcc.
+
+  Pinguino mips-elf Toolchain
+  ---------------------------
+
+  Another option is the mips-elf toolchain used with the Pinguino project.  This
+  is a relatively current mips-elf GCC and should provide free C++ support as
+  well. This toolchain can be downloded from the Pinguino website:
+  http://wiki.pinguino.cc/index.php/Main_Page#Download . There is some general
+  information about using the Pinguino mips-elf toolchain in this thread:
+  http://tech.groups.yahoo.com/group/nuttx/message/1821
+
+  Support for the Pinguino mips-elf toolchain has been included in the Mirtoo
+  configurations.  Use one of these configuration options to select the Pinguino
+  mips-elf toolchain:
+
+    CONFIG_PIC32MX_PINGUINOW - Pinguino mips-elf toolchain for Windows
+    CONFIG_PIC32MX_PINGUINOL - Pinguino mips toolchain for Linux
+
+  And set the path appropriately in the setenv.sh file.  These tool configurations
+  are untested -- expect some additional integration issues.  Good luck!
+
+  MPLAB/C32 vs MPLABX/X32
+  -----------------------
+
+  It appears that Microchip is phasing out the MPLAB/C32 toolchain and replacing
+  it with MPLABX and XC32.  At present, the XC32 toolchain is *not* compatible
+  with the NuttX build scripts.  Here are some of the issues that I see when trying
+  to build with XC32:
+
+  1) Make.def changes:  You have to change the tool prefix:
+
+     CROSSDEV=xc32-
+
+  2) debug.ld/release.ld:  The like expect some things that are not present in
+     the current linker scripts (or are expected with different names).  Here
+     are some partial fixes:
+
+     Rename:  kseg0_progmem to kseg0_program_mem
+     Rename:  kseg1_datamem to kseg1_data_mem
+
+  Even then, there are more warnings from the linker and some undefined symbols
+  for non-NuttX code that resides in the unused Microchip libraries.  See this
+  email thread at http://tech.groups.yahoo.com/group/nuttx/message/1458 for more
+  information.  You will have to solve at least this undefined symbol problem if
+  you want to used the XC32 toolchain.
+
+  Windows Native Toolchains
+  -------------------------
+
+  NOTE:  There are several limitations to using a Windows based toolchain in a
+  Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+Loading NuttX with ICD3
+========================
+
+  Intel Hex Forma Files:
+  ----------------------
+
+    When NuttX is built it will produce two files in the top-level NuttX
+    directory:
+
+    1) nuttx - This is an ELF file, and
+    2) nuttx.hex - This is an Intel Hex format file.  This is controlled by
+       the setting CONFIG_INTELHEX_BINARY in the .config file.
+
+    The PICkit tool wants an Intel Hex format file to burn into FLASH. However,
+    there is a problem with the generated nutt.hex: The tool expects the nuttx.hex
+    file to contain physical addresses.  But the nuttx.hex file generated from the
+    top-level make will have address in the KSEG0 and KSEG1 regions.
+
+  tools/pic32mx/mkpichex:
+  ----------------------
+
+    There is a simple tool in the NuttX tools/pic32mx directory that can be
+    used to solve both issues with the nuttx.hex file.  But, first, you must
+    build the tool:
+
+      cd tools/pic32mx
+      make
+
+    Now you will have an excecutable file call mkpichex (or mkpichex.exe on
+    Cygwin).  This program will take the nutt.hex file as an input, it will
+    convert all of the KSEG0 and KSEG1 addresses to physical address, and
+    it will write the modified file, replacing the original nuttx.hex.
+
+    To use this file, you need to do the following things:
+
+      . ./setenv.sh    # Source setenv.sh.  Among other this, this script
+                       # will add the NuttX tools/pic32mx directory to your
+                       # PATH variable
+      make             # Build nuttx and nuttx.hex
+      mkpichex $PWD    # Convert addresses in nuttx.hex.  $PWD is the path
+                       # to the top-level build directory.  It is the only
+                       # required input to mkpichex.
+
+LED Usage
+=========
+
+  The Mirtoo module has 2 user LEDs labeled LED0 and LED1 in the schematics:
+
+    ---  ----- --------------------------------------------------------------
+    PIN  Board Notes
+    ---  ----- --------------------------------------------------------------
+    RC8  LED0  Grounded, high value illuminates
+    RC9  LED1  Grounded, high value illuminates
+
+  The Dimitech DTX1-4000L EV-kit1 supports 3 more LEDs, but there are not
+  controllable from software.
+
+  If CONFIG_ARCH_LEDS is defined, then NuttX will control these LEDs as
+  follows:
+                                 ON        OFF
+    ------------------------- ---- ---- ---- ----
+                              LED0 LED1 LED0 LED1
+    ------------------------- ---- ---- ---- ----
+    LED_STARTED            0  OFF  OFF  ---  ---
+    LED_HEAPALLOCATE       1  ON   OFF  ---  ---
+    LED_IRQSENABLED        2  OFF  ON   ---  ---
+    LED_STACKCREATED       3  ON   ON   ---  ---
+    LED_INIRQ              4  ON   N/C  OFF  N/C
+    LED_SIGNAL             4  ON   N/C  OFF  N/C
+    LED_ASSERTION          4  ON   N/C  OFF  N/C
+    LED_PANIC              4  ON   N/C  OFF  N/C
+
+UART Usage
+==========
+
+  When mounted on the DTX1-4000L EV-kit1 board, serial output is avaiable through
+  an FT230X device via the FUNC0 and FUNC1 module outputs.  If CONFIG_PIC32MX_UART2
+  is enabled, the src/up_boot will configure the UART2 pins as follows:
+
+    ---------- ------ ----- ------ -------------------------
+       BOARD   MODULE  PIN  SIGNAL NOTES
+    ---------- ------ ----- ------ -------------------------
+    FT230X RXD  FUNC0 RPB11  U2RX  UART2 RX (Also PGEC2)
+    FT230X TXD  FUNC1 RPB10  U2TX  UART2 TX (Also PGED2)
+
+  However, since the FUNC0/1 pins are shared with the PGEC/D2, they cannot be used
+  for UART2 if you are also debugging with the ICD3.  In that case, you may need
+  to switch to UART1.
+
+  If CONFIG_PIC32MX_UART1 is enabled, the src/up_boot will configure the UART
+  pins as follows.  This will support communictions (via an external RS-232
+  driver) through X3 pins 4 and 5:
+
+    ---------- ------ ----- ------ -------------------------
+       BOARD   MODULE  PIN  SIGNAL NOTES
+    ---------- ------ ----- ------ -------------------------
+    X3, pin 4   FUNC4 RPBC5  U1TX  UART1 TX
+    X3, pin 5   FUNC5 RPBC6  U1RX  UART1 RX
+
+  If you are not using MPLAB to debug, you may also want to change Make.defs
+  to use the release.ld linker script instead of the debug.ld link script.  This
+  change will give you a little more memory by re-using the boot FLASH and SRAM
+  that would otherwise be reserved for MPLAB.
+
+Analog Input
+============
+
+  The Mirtoo features a PGA117 amplifier/multipexer that can be configured to
+  bring any analog signal from PORT0,.. PORT7 to pin 19 of the PIC32MX:
+
+  --- ------------------------------------------------ ----------------------------
+  PIN PIC32 SIGNAL(s)                                  BOARD SIGNAL/USAGE
+  --- ------------------------------------------------ ----------------------------
+  19  PGED3/VREF+/CVREF+/AN0/C3INC/RPA0/CTED1/PMD7/RA0 AIN PGA117 Vout
+  --- ------------------------------------------------ ----------------------------
+
+  The PGA117 driver can be enabled by setting the following the the nsh
+  configuration:
+
+    CONFIG_ADC=y         : Enable support for analog input devices
+    CONFIG_PIC32MX_ADC=y : Enable support the PIC32 ADC driver
+    CONFIG_SPI_OWNBUS=n  : The PGA117 is *not* the only device on the bus
+    CONFIG_ADC_PGA11X=y  : Enable support for the PGA117
+
+  When CONFIG_PIC32MX_ADC=y is defined, the Mirtoo boot up logic will
+  automatically configure pin 18 (AN0) as an analog input (see configs/mirtoo/src/up_adc.c).
+  To intialize and use the PGA117, you to add logic something like the
+  following in your application code:
+
+  #include <nuttx/spi.h>
+  #include <nuttx/analog/pga11x.h>
+
+  FAR struct spi_dev_s *spi;
+  PGA11X_HANDLE handle;
+
+  /* Get the SPI port */
+
+  spi = up_spiinitialize(2);
+  if (!spi)
+    {
+      dbg("ERROR: Failed to initialize SPI port 2\n");
+      return -ENODEV;
+    }
+
+  /* Now bind the SPI interface to the PGA117 driver */
+
+  handle = pga11x_initialize(spi);
+  if (!handle)
+    {
+      dbg("ERROR: Failed to bind SPI port 2 to the PGA117 driver\n");
+      return -ENODEV;
+    }
+
+  After that initialization is set, then one of PORT0-7 can be select as
+  an analog input to AN0 like:
+
+  struct pga11x_settings_s settings;
+  int ret;
+
+  settings.channel = PGA11X_CHAN_CH2;
+  settings.gain    = PGA11X_GAIN_2;
+
+  ret = pga11x_select(handle, &settings);
+  if (ret < 0)
+    {
+      dbg("ERROR: Failed to select channel 2, gain 2\n");
+      return -EIO;
+    }
+
+  The above logic may belong in configs/mirtoo/src/up_adc.c?
+
+  There is still one missing piece to complete the analog support on the
+  Mirtoo.  This is the ADC driver that collects analog data and provides
+  and ADC driver that can be used with standard open, close, read, and write
+  interfaces.  To complete this driver, the following is needed:
+
+  (1) arch/mips/src/pic32mx/pic32mx-adc.c.  The ADC driver that implements
+      the ADC interfaces defined in include/nuttx/analog/adc.h and must
+      be built when CONFIG_PIC32MX_ADC is defined.
+
+  (2) configs/mirtoo/up_adc.c.  Add Mirtoo logic that initializes and
+      registers the ADC driver.
+
+  A complete ADC driver will be a considerable amount of work to support
+  all of the ADC features (such as timer driven sampling).  If all you want
+  to do is a simple analog conversion, then in lieu of a real ADC driver,
+  you can use simple in-line logic such as you can see in the PIC32MX7 MMB
+  touchscreen driver at configs/pic32mx7mmb/src/up_touchscreen.c
+
+PIC32MX Configuration Options
+=============================
+
+  General Architecture Settings:
+
+    CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+     be set to:
+
+       CONFIG_ARCH=mips
+
+    CONFIG_ARCH_family - For use in C code:
+
+       CONFIG_ARCH_MIPS=y
+
+    CONFIG_ARCH_architecture - For use in C code:
+
+       CONFIG_ARCH_MIPS32=y
+
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+       CONFIG_ARCH_CHIP=pic32mx
+
+    CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+       chip:
+
+       CONFIG_ARCH_CHIP_PIC32MX250F128D=y
+
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+
+       CONFIG_ARCH_BOARD=mirtoo
+
+    CONFIG_ARCH_BOARD_name - For use in C code
+
+       CONFIG_ARCH_BOARD_MIRTOO=y
+
+    CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+       of delay loops
+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_DRAM_SIZE - Describes the installed DRAM (CPU SRAM in this case):
+
+       CONFIG_DRAM_SIZE=(32*1024) (32Kb)
+
+       There is an additional 32Kb of SRAM in AHB SRAM banks 0 and 1.
+
+    CONFIG_DRAM_START - The start address of installed DRAM
+
+       CONFIG_DRAM_START=0xa0000000
+
+    CONFIG_ARCH_IRQPRIO - The PIC32MXx supports interrupt prioritization
+
+       CONFIG_ARCH_IRQPRIO=y
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+       stack. If defined, this symbol is the size of the interrupt
+       stack in bytes.  If not defined, the user task stacks will be
+       used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.

+
+Configurations
+==============
+
+Each PIC32MX configuration is maintained in a sudirectory and can be
+selected as follow:
+
+    cd tools
+    ./configure.sh mirtoo/<subdir>
+    cd -
+    . ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  ostest:
+  =======
+    This configuration directory, performs a simple OS test using
+    apps/examples/ostest.  This configuration use UART1 which is
+    available on FUNC 4 and 5 on connector X3:
+
+      CONFIG_PIC32MX_UART1=y           : UART1 for serial console
+      CONFIG_UART1_SERIAL_CONSOLE=n
+
+    If you are not using MPLAB to debug, you may switch to UART2
+    by editting the .config file after configuration to disable UART1
+    and select UART2.  You should also change Make.defs to use the
+    release.ld linker script instead of the debug.ld link script.
+
+    This configuration also uses the Microchip C32 toolchain under
+    windows by default:
+
+      CONFIG_PIC32MX_MICROCHIPW_LITE=y : Lite version of windows toolchain
+
+    To switch to the Linux C32 toolchain you will have to change (1) the
+    toolchain selection in .config (after configuration) and (2) the
+    path to the toolchain in setenv.sh.  See notes above with regard to
+    the XC32 toolchain.
+
+  nsh:
+  ====
+    This configuration directory holds configuration files tht can
+    be used to support the NuttShell (NSH).  This configuration use
+    UART1 which is available on FUNC 4 and 5 on connector X3:
+
+      CONFIG_PIC32MX_UART1=y           : UART1 for serial console
+      CONFIG_UART1_SERIAL_CONSOLE=n
+
+    UART2
+    -----
+    If you are not using MPLAB to debug, you may switch to UART2
+    by following the instructions above for the ostest configuration.
+
+    This configuration also uses the Microchip C32 toolchain under
+    windows by default:
+
+      CONFIG_PIC32MX_MICROCHIPW_LITE=y : Lite version of windows toolchain
+
+    To switch to the Linux C32 toolchain you will have to change (1) the
+    toolchain selection in .config (after configuration) and (2) the
+    path to the toolchain in setenv.sh.  See notes above with regard to
+    the XC32 toolchain.
+
+    PGA117 Support:
+    --------------
+    The Mirtoo's PGA117 amplifier/multipexer is not used by this configuration
+    but can be enabled by setting:
+
+       CONFIG_ADC=y         : Enable support for analog input devices
+       CONFIG_SPI_OWNBUS=y  : If the PGA117 is the only device on the bus
+       CONFIG_ADC_PGA11X=y  : Enable support for the PGA117
+
+  nxffs:
+  ======
+    This is a configuration very similar to the nsh configuration.  This
+    configure also provides the NuttShell (NSH).  And this configuration use
+    UART1 which is available on FUNC 4 and 5 on connector X3 (as described
+    for the nsh configuration).  This configuration differs from the nsh
+    configuration in the following ways:
+
+    1) It uses the Pinguino toolchain be default (this is easily changed,
+       see above).
+
+       CONFIG_PIC32MX_PINGUINOW=y
+
+    2) SPI2 is enabled and support is included for the NXFFS file system
+       on the 32Mbit SST25 device on the Mirtoo board.  NXFFS is the NuttX
+       wear-leveling file system.
+
+       CONFIG_PIC32MX_SPI2=y
+       CONFIG_MTD_SST25=y
+       CONFIG_SST25_SECTOR512=y
+       CONFIG_DISABLE_MOUNTPOINT=n
+       CONFIG_FS_NXFFS=y
+       CONFIG_NSH_ARCHINIT=y
+
+    3) Many operating system features are suppressed to produce a smaller
+       footprint.
+
+       CONFIG_SCHED_WAITPID=n
+       CONFIG_DISABLE_POSIX_TIMERS=y
+       CONFIG_DISABLE_PTHREAD=y
+       CONFIG_DISABLE_MQUEUE=y
+       CONFIG_DISABLE_MQUEUE=y
+
+    4) Many NSH commands are suppressed, also for a smaller FLASH footprint
+
+       CONFIG_NSH_DISABLESCRIPT=y
+       CONFIG_NSH_DISABLEBG=y
+
+       CONFIG_NSH_DISABLE_DD=y
+       CONFIG_NSH_DISABLE_EXEC=y
+       CONFIG_NSH_DISABLE_EXIT=y
+       CONFIG_NSH_DISABLE_GET=y
+       CONFIG_NSH_DISABLE_IFCONFIG=y
+       CONFIG_NSH_DISABLE_KILL=y
+       CONFIG_NSH_DISABLE_MKFATFS=y
+       CONFIG_NSH_DISABLE_MKFIFO=y
+       CONFIG_NSH_DISABLE_MKRD=y
+       CONFIG_NSH_DISABLE_NFSMOUNT=y
+       CONFIG_NSH_DISABLE_PING=y
+       CONFIG_NSH_DISABLE_PUT=y
+       CONFIG_NSH_DISABLE_SH=y
+       CONFIG_NSH_DISABLE_TEST=y
+       CONFIG_NSH_DISABLE_WGET=y
+
+    When the system boots, you should have the NXFFS file system mounted
+    at /mnt/sst25.
+
+    NOTES:  (1) It takes many seconds to boot the sytem using the NXFFS
+    file system because the entire FLASH must be verified on power up
+    (and longer the first time that NXFFS comes up and has to format the
+    entire FLASH). (2) FAT does not have these delays and this configuration
+    can be modified to use the (larger) FAT file system as described below.
+    But you will, or course, lose the wear-leveling feature if FAT is used.
+
+    fat:
+    ----
+    There is no FAT configuration, but the nxffx configuration can be used
+    to support the FAT FS if the following changes are made to the NuttX
+    configuration file:
+
+      CONFIG_FS_NXFFS=n
+      CONFIG_FS_FAT=y
+      CONFIG_NSH_DISABLE_MKFATFS=n
+
+    In this configuration, the FAT file system will not be automatically
+    monounted.  When NuttX boots to the NSH prompt, you will find the
+    SST5 block driver at /dev/mtdblock0.  This can be formatted with a
+    FAT file system and mounted with these commands:
+
+      nsh> mkfatfs /dev/mtdblock0
+      nsh> mount -t vfat /dev/mtdblock0 /mnt/sst25
+
+    PGA117 Support:
+    ---------------
+    The Mirtoo's PGA117 amplifier/multipexer is not used by this configuration
+    but can be enabled by setting:
+
+      CONFIG_ADC=y         : Enable support for anlog input devices
+      CONFIG_SPI_OWNBUS=n  : The PGA117 is *not* the only device on the bus
+      CONFIG_ADC_PGA11X=y  : Enable support for the PGA117

+ *   defined by struct spi_ops_s (see include/nuttx/spi.h). All other methods 
+ *   including up_spiinitialize()) are provided by common PIC32MX logic.  To use

+ *
+ *   1. Provide logic in pic32mx_boardinitialize() to configure SPI chip select
+ *      pins.
+ *   2. Provide pic32mx_spiNselect() and pic32mx_spiNstatus() functions
+ *      in your board-specific logic.  These functions will perform chip selection
+ *      and status operations using GPIOs in the way your board is configured.
+ *   2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
+ *      pic32mx_spiNcmddata() functions in your board-specific logic.  These
+ *      functions will perform cmd/data selection operations using GPIOs in the way
+ *      your board is configured.
+ *   3. Add a call to up_spiinitialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by up_spiinitialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling 
+ *      mmcsd_spislotinitialize(), for example, will bind the SPI driver to
+ *      the SPI MMC/SD driver).

+
+Toolchain
+^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the ARM920T GCC toolchain (if
+  different from the default).
+
+  If you have no ARM toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+
+  1. You must have already configured Nuttx in <some-dir>nuttx.
+
+     cd tools
+     ./configure.sh mx1ads/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/arm920t-defconfig-4.2.4 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h so that the PATH variable includes the path to the
+     newly built binaries.
+
+ARM/i.MX1-specific Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+	   be set to:
+
+	   CONFIG_ARCH=arm
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_ARM=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_ARM920T=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=imx
+
+	CONFIG_ARCH_CHIP_name - For use in C code.  Could be line _IMX1,
+	   _IMXL, _IMX21, _IMX27, _IMX31, etc. (not all of which are
+	   supported).
+
+	   CONFIG_ARCH_CHIP_IMX1
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=mx1ads (for the Freescale MX1ADS evaluation board)
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_MX1ADS (for the Spectrum Digital C5471 EVM)
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - Describes the installed DRAM.
+
+	CONFIG_DRAM_START - The start address of installed DRAM
+
+	CONFIG_DRAM_VSTART - The startaddress of DRAM (virtual)
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	   stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.
+
+  IMX specific device driver settings
+
+	CONFIG_UARTn_SERIAL_CONSOLE - selects the UARTn for the
+	   console and ttys0 (default is the UART0).
+	CONFIG_UARTn_RXBUFSIZE - Characters are buffered as received.
+	   This specific the size of the receive buffer
+	CONFIG_UARTn_TXBUFSIZE - Characters are buffered before
+	   being sent.  This specific the size of the transmit buffer
+	CONFIG_UARTn_BAUD - The configure BAUD of the UART.  Must be
+	CONFIG_UARTn_BITS - The number of bits.  Must be either 7 or 8.
+	CONFIG_UARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
+	CONFIG_UARTn_2STOP - Two stop bits
+
+  IMX USB Configuration
+
+	CONFIG_IMX_GIO_USBATTACH
+	   GIO that detects USB attach/detach events
+	CONFIG_IMX_GIO_USBDPPULLUP
+	   GIO 
+	CONFIG_DMA320_USBDEV_DMA
+	   Enable IMX-specific DMA support
+	CONFIG_IMX_GIO_USBATTACH=6
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each MX1ADS configuration is maintained in a sudirectory and
+can be selected as follow:
+
+	cd tools
+	./configure.sh imxads/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+ostest
+^^^^^^
+
+This configuration directory, performs a simple OS test using
+examples/ostest.

+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development
+  environment. The source has been built only using the GNU toolchain
+  (see below).  Other toolchains will likely cause problems.
+
+NuttX Buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the HC12 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no HC12 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin
+  environments.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh ne64badge/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/m9s12x-defconfig-3.3.6 .config
+
+  6. make oldconfig
+
+  7. make
+
+     If the make fails because it can't find the file to download, you may
+     have to locate the file on the internet and download it into the archives/
+     directory manually.  For example, binutils-2.18 can be found here:
+     http://ftp.gnu.org/gnu/binutils/
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you are
+  building a Cortex-M3 toolchain for Cygwin under Windows.
+
+FreeScale HCS12 Serial Monitor
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  General:
+    The NuttX HCS12 port is configured to use the Freescale HCS serial
+    monitor.  This monitor supports primitive debug commands that allow
+    FLASH/EEPROM programming and debugging through an RS-232 serial
+    interface.  The serial monior is 2Kb in size and resides in FLASH at
+    addresses 0xf800-0xffff.  The monitor does not use any RAM other than
+    the stack itself.
+
+  AN2458
+    The serial monitor is described in detail in Freescale Application
+    Note AN2458.pdf.
+
+  COP:
+    The serial monitor uses the COP for the cold reset function and should
+    not be used by the application without some precautions (see AN2458).
+
+  Clocking:
+    The serial monitor sets the operating frequency to 24 MHz.  This is
+    not altered by the NuttX start-up; doing so would interfere with the
+    operation of the serial monitor.
+
+  Memory Configuration:
+    Registers:
+    • Register space is located at 0x0000–0x03ff.
+    FLASH:
+    • FLASH memory is any address greater than 0x4000. All paged
+      addresses are assumed to be FLASH memory.
+    • Application code should exclude the 0xf780–0xff7f memory.
+    SRAM:
+    • RAM ends at 0x3FFF and builds down to the limit of the device’s
+      available RAM.
+    • The serial monitor's stack pointer is set to the end of RAM+1
+      (0x4000).
+    EEPROM:
+    • EEPROM (if the target device has any) is limited to the available
+      space between the registers and the RAM (0x0400–to start of RAM).
+    External Devices:
+    • External devices attached to the multiplexed external bus
+      interface are not supported
+
+  Serial Communications:
+    The serial monitor uses RS-232 serial communications through SCI0 at
+    115,200 baud. The monitor must have exclusive use of this interface.
+    Access to the serial port is available through a monitor jump table.
+
+  Interrrupts:
+    The serial monitor redirects interrupt vectors to an unprotected
+    portion of FLASH just before the protected monitor program
+    (0xf780–0xf7fe).  The monitor will automatically redirect vector
+    programming operations to these user vectors.  The user code should
+    therefore keep the normal (non-monitor) vector locations
+    (0xff80–0xfffe).
+
+Soft Registers
+^^^^^^^^^^^^^^
+
+  The mc68hcs12 compilation is prone to errors like the following:
+
+    CC:  lib_b16sin.c
+    lib_b16sin.c: In function `b16sin':
+    lib_b16sin.c:110: error: unable to find a register to spill in class `S_REGS'
+    lib_b16sin.c:110: error: this is the insn:
+    (insn:HI 41 46 44 8 (parallel [
+                (set (subreg:SI (reg:DI 58 [ rad ]) 4)
+                    (reg/v:SI 54 [ rad ]))
+                (clobber (scratch:HI))
+            ]) 20 {movsi_internal} (insn_list 46 (nil))
+        (expr_list:REG_UNUSED (scratch:HI)
+            (expr_list:REG_NO_CONFLICT (reg/v:SI 54 [ rad ])
+                (nil))))
+    lib_b16sin.c:110: confused by earlier errors, bailing out
+
+  There are several ways that this error could be fixed:
+
+  1. Increase the number of soft registers (i.e., "fake" registers defined
+     at fixed memory locations).  This can be done by adding something like
+     -msoft-reg-count=4 to the CFLAGS.  This approach was not taken
+     because:
+
+     - This slows hcs12 performance
+     - All of these soft registers wouil have to be saved and restored
+       on every interrupt and context switch.
+
+  2. Lowering the optimization level by dropping -Os to -O2 or, more likely,
+     by removing -fomit-frame-pointer.  Also not desireable becauase 99% of the
+     files that do not have this problem also increase in size.  Special case
+     compilation with reduced optimization levels just for the files that need
+     it could be done, but this would complicate the make system.
+
+  3. Restructuring files to reduce the complexity.  If you add local variables
+     to hold intermediate computational results, this error can be eliminated.
+     This is the approach taken in NuttX.  It has disadvantages only in that
+     (1) it takes some effort and good guessing to eliminate the problem, and (2)
+     the problem is not really eliminated -- it can and will re-occur when files
+     are changed or new files are added.
+
+  4. Many files are built that are needed by DEM09S12NE64.  Another very simple
+     option if those problem files are needed is to just remove the offending
+     files from the Make.defs file so that they no longer cause a problem.
+
+HCS12/NE64BADGE-specific Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+	   be set to:
+
+	   CONFIG_ARCH=hc
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_HC=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_HCS12=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=mc92s12nec64
+
+	CONFIG_ARCH_CHIP_name - For use in C code
+
+	   CONFIG_ARCH_CHIP_MCS92S12NEC64
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=ne64badge
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_NE64BADGE (for the Future Electronics Group NE64 Badge)
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - Describes the installed RAM.
+
+	CONFIG_DRAM_START - The start address of installed RAM
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	   stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.

+	CONFIG_HCS12_SERIALMON - Indicates that the target systems uses
+	  the Freescale serial bootloader.
+
+	CONFIG_HCS12_NONBANKED - Indicates that the target systems does not
+	  support banking.  Only short calls are made; one fixed page is
+	  presented the the paging window.  Only 48Kb of FLASH is usable
+	  in this configuration: pages 3e, 3d, then 3f will appear as a
+	  contiguous address space in memory.
+
+  HCS12 Sub-system support
+
+	CONFIG_HCS12_SCI0
+	CONFIG_HCS12_SCI1
+
+  HCS12 specific device driver settings:

+
+	CONFIG_SCIn_RXBUFSIZE - Characters are buffered as received.
+	   This specific the size of the receive buffer
+
+	CONFIG_SCIn_TXBUFSIZE - Characters are buffered before
+	   being sent.  This specific the size of the transmit buffer
+
+	CONFIG_SCIn_BAUD - The configure BAUD of the UART.
+

+Dev vs. Production Neuros OSD v1.0 boards
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  This port supports both the original Neuros OSD v1.0 Dev Board.
+  This port has recently been extended to V1.0 Production board (and
+  that is now the default configuration). References:
+
+    http://www.neurostechnology.com/neuros-developer-community
+    http://wiki.neurostechnology.com/index.php/OSD_1.0_Developer_Home
+    http://wiki.neurostechnology.com/index.php/DM320_Platform_development
+
+  There are some differences between the Dev Board and the currently
+  available commercial v1.0 Boards, most notably in the amount of memory:
+  8Mb FLASH and 32Mb RAM vs. 16Mb and 64Mb as in the production board.
+  See the following for more information:
+    
+     http://wiki.neurostechnology.com/index.php/OSD_Developer_Board_v1
+
+  NuttX operates on the ARM9EJS of this dual core processor.  The DSP
+  is available and unused.
+
+  STATUS: This port is code complete, verified, and included in the
+  NuttX 0.2.1 release.
+
+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. Raisonance GNU toolchain, or
+  4. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery, devkitARM or Raisonance GNU toolchain, you simply need to
+  add one of the following configuration options to your .config (or defconfig)
+  file:
+
+    CONFIG_DM320_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_DM320_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_DM320_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_DM320_BUILDROOT=y	  : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_DM320_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows), devkitARM, and Raisonance toolchains are
+  Windows native toolchains.  The CodeSourcey (for Linux) and NuttX buildroot
+  toolchains are Cygwin and/or Linux native toolchains. There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+^^^^
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project (There is a simple RIDE project
+  in the RIDE subdirectory).
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/dm320,
+     arch/arm/src/common, arch/arm/src/arm, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/arm/up_head.S.  You may have to build the NuttX
+  one time from the Cygwin command line in order to obtain the pre-built
+  startup object needed by the IDE.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the ARM926 GCC toolchain (if
+  different from the default).
+
+  If you have no ARM toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+
+  1. You must have already configured Nuttx in <some-dir>nuttx.
+
+     cd tools
+     ./configure.sh ntosd-dm320/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/arm-defconfig .config OR
+     cp configs/arm926t_defconfig-4.2.4 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h so that the PATH variable includes the path to the
+     newly built binaries.
+
+ARM/DM320-specific Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+	   be set to:
+
+	   CONFIG_ARCH=arm
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_ARM=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_ARM926EJS=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=dm320
+
+	CONFIG_ARCH_CHIP_name - For use in C code
+
+	   CONFIG_ARCH_CHIP_DM320
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=ntosd-dm320
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_NTOSD_DM320 (for the Spectrum Digital C5471 EVM)
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - Describes the installed DRAM.
+
+	CONFIG_DRAM_START - The start address of installed DRAM
+
+	CONFIG_DRAM_VSTART - The startaddress of DRAM (virtual)
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt

+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay

+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+nettest

+
+udp
+^^^
+
+This alternative configuration directory is similar to nettest
+except that is use examples/upd to exercise UDP.
+
+uip
+^^^
+
+This configuration file demonstrates the tiny webserver
+at examples/uip.
+

+http://wiki.neurostechnology.com/index.php/The_Neuros_and_Open_Source
+...
+
+Status:
+^^^^^^^
+
+NOTE:  These instructions are for the Neuros development board (and a
+rather old version of NuttX),
+http://wiki.neurostechnology.com/index.php/OSD_Developer_Board_v1
+and have _not_ been updated for the Neuros OSD 1.0 consumer unit
+(or for the current version of NuttX),
+http://wiki.neurostechnology.com/index.php/Neuros_OSD_1.0
+
+At present, the system only supports a serial console and timer
+interrupts so there is not to much that you can do with it.  But I
+would be happy to work with anyone who is interested in using it.
+
+General instructions.
+
+1. Download build-0.1.0.tar.gz and nuttx-0.2.3.tar.gz into the same
+   <directory>.  These are the current versions as of this writing
+   (but could very well new older release now).
+
+2. Unpack, you should now have <directory>/buildroot and
+   <directory>/nuttx-0.2.3
+
+3. Rename nuttx-0.2.3 to nuttx
+
+4. Configure NuttX:
+
+   cd <directory>/nuttx/tools
+  ./configure.sh ntosd-dm320
+
+5. Build the toolchain:
+
+  cd <directory>/buildroot
+  cp configs/c5471-defconfig .config
+  make oldconfig
+  make
+
+6. Build Nuttx:
+
+  cd <directory>nuttx
+  . ./setenv.sh
+  make
+  mv nuttx /tftpboot/nuttx.dm320
+
+7. Configure the OSD u-boot:
+
+   Neuros Devboard > set ipaddr yy.yy.yy.yy
+   Neuros Devboard > set serverip xx.xx.xx.xx
+   Neuros Devboard > ...
+   Neuros Devboard > run update-ipstatic
+
+   where yy.yy.yy.yy is the OSD IP address and xx.xx.xx.xx is
+   the host PC address.
+
+8. Load and run nuttx from uboot
+
+  tftpboot xx.xx.xx.xx nuttx.dm320
+  go 1008000
+
+What will run is an a simple OS test that will verify many of the
+features of the OS.  (this is nutts/examples/ostest).

+
+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery or devkitARM toolchain, you simply need add one of the
+  following configuration options to your .config (or defconfig) file:
+
+    CONFIG_LPC17_CODESOURCERYW=y   : CodeSourcery under Windows
+    CONFIG_LPC17_CODESOURCERYL=y   : CodeSourcery under Linux
+    CONFIG_LPC17_DEVKITARM=y       : devkitARM under Windows
+    CONFIG_LPC17_BUILDROOT=y       : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_LPC17_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows)and devkitARM are Windows native toolchains.
+  The CodeSourcey (for Linux) and NuttX buildroot toolchains are Cygwin and/or
+  Linux native toolchains. There are several limitations to using a Windows based
+  toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+^^^^
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project (There is a simple RIDE project
+  in the RIDE subdirectory).
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/lpc17xx,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/lpc17x/lpc17_vectors.S.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh nucleus2g/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you
+  are building a Cortex-M3 toolchain for Cygwin under Windows.
+
+  NOTE: This is an OABI toolchain.
+
+LEDs
+^^^^
+
+  If CONFIG_ARCH_LEDS is defined, then support for the Nucleus-2G LEDs will be
+  included in the build.  See:
+
+  - configs/nucleus2g/include/board.h - Defines LED constants, types and
+    prototypes the LED interface functions.
+
+  - configs/nucleus2g/src/nucleus2g_internal.h - GPIO settings for the LEDs.
+
+  - configs/nucleus2g/src/up_leds.c - LED control logic.
+
+  The Nucleus2G has 3 LEDs... two on the Babel CAN board and a "heartbeat" LED."
+  The LEDs on the Babel CAN board are capabl of OFF/GREEN/RED/AMBER status.
+  In normal usage, the two LEDs on the Babel CAN board would show CAN status, but if
+  CONFIG_ARCH_LEDS is defined, these LEDs will be controlled as follows for NuttX
+  debug functionality (where NC means "No Change").
+
+  During the boot phases.  LED1 and LED2 will show boot status.
+
+                                          /* LED1   LED2   HEARTBEAT */
+    #define LED_STARTED                0  /* OFF    OFF    OFF */
+    #define LED_HEAPALLOCATE           1  /* GREEN  OFF    OFF */
+    #define LED_IRQSENABLED            2  /* OFF    GREEN  OFF */
+    #define LED_STACKCREATED           3  /* OFF    OFF    OFF */
+
+    #define LED_INIRQ                  4  /*  NC     NC    ON  (momentary) */
+    #define LED_SIGNAL                 5  /*  NC     NC    ON  (momentary) */
+    #define LED_ASSERTION              6  /*  NC     NC    ON  (momentary) */
+    #define LED_PANIC                  7  /*  NC     NC    ON  (2Hz flashing) */
+    #undef  LED_IDLE                      /* Sleep mode indication not supported */
+
+  After the system is booted, this logic will no longer use LEDs 1 and 2.  They
+  are then available for use the application software using lpc17_led1() and
+  lpc17_led2():
+
+    enum lpc17_ledstate_e
+    {
+      LPC17_LEDSTATE_OFF   = 0,
+      LPC17_LEDSTATE_GREEN = 1,
+      LPC17_LEDSTATE_RED   = 2,
+      LPC17_LEDSTATE_AMBER = (LPC17_LEDSTATE_GREEN|LPC17_LEDSTATE_RED),
+    };
+
+    EXTERN void lpc17_led1(enum lpc17_ledstate_e state);
+    EXTERN void lpc17_led2(enum lpc17_ledstate_e state);
+
+  The heartbeat LED is illuminated during all interrupt and signal procressing.
+  Normally, it will glow dimly to inicate that the LPC17xx is taking interrupts.
+  On an assertion PANIC, it will flash at 2Hz.
+

+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	    stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.

+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that

+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.

+
+Configurations
+^^^^^^^^^^^^^^
+
+Each Nucleus 2G configuration is maintained in a
+sudirectory and can be selected as follow:
+
+	cd tools
+	./configure.sh nucleus2g/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  nsh:
+    Configures the NuttShell (nsh) located at examples/nsh.  The
+    Configuration enables only the serial  NSH interfaces.
+
+  ostest:
+    This configuration directory, performs a simple OS test using
+    examples/ostest.
+
+  usbserial:
+    This configuration directory exercises the USB serial class
+    driver at examples/usbserial.  See examples/README.txt for
+    more information.
+
+  usbstorage:
+    This configuration directory exercises the USB mass storage
+    class driver at examples/usbstorage.  See examples/README.txt for
+    more information.

+ *   must be provided by board-specific logic.  They are implementations of the select

+ *   are provided by common LPC17xx logic.  To use this common SPI logic on your
+ *   board:
+ *
+ *   1. Provide logic in lpc17_boardinitialize() to configure SPI/SSP chip select
+ *      pins.
+ *   2. Provide lpc17_ssp0/ssp1select() and lpc17_ssp0/ssp1status() functions
+ *      in your board-specific logic.  These functions will perform chip selection
+ *      and status operations using GPIOs in the way your board is configured.
+ *   3. Add a calls to up_spiinitialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by up_spiinitialize() may then be used to bind the

+
+Repair procedure for ARM-USB-OCD drivers
+
+1.   Uninstalling ARM-USB-OCD drivers
+-------------------------------------
+1.1. Connect your programmer/debugger to your computer, open Device Manager
+     and uninstall the drivers for ARM-USB-OCD.
+1.2. After you have uninstalled ARM-USB-TINY driver from Device Manager,
+     disconnect the programmer from your computer.
+1.3. Now you should download FTClean.exe from here:
+     http://www.ftdichip.com/Support/Utilities/FTClean.zip.
+1.4. After download is complete extract the "*.zip" file, open folder FTClean,
+     and run FTClean.exe
+1.5. Ror VID (Hex) select "Other". And after that fill the first box with 15ba
+     and "PID (Hex)" with 0004.
+1.6. Press "Clean System" button.  Make sure that all FTDI devices are
+     disconnected. (My require administrator privileges).
+
+2. Re-installing the ARM-USB-OCD driver
+---------------------------------------
+2.1 Connect the programmer/debugger to the computer.
+2.2 When prompted, browse to the C:\gccfd\DRIVERS\ARM-USB-OCD-DRIVER
+    directory and install. (A different driver is required for OpenOCD
+    0.4.0.  That driver is available from the olimex.com web site).

+
+  Serial Console
+  --------------
+
+  The LPC1766-STK board has two serial connectors.  One, RS232_0, connects to
+  the LPC1766 UART0.  This is the DB-9 connector next to the power connector.
+  The other RS232_1, connect to the LPC1766 UART1.  This is he DB-9 connector
+  next to the Ethernet connector.
+
+  Simple UART1 is the more flexible UART and since the needs for a serial
+  console are minimal, the more minimal UART0/RS232_0 is used for the NuttX
+  system console.  Of course, this can be changed by editting the NuttX
+  configuration file as discussed below.
+
+  The serial console is configured as follows (57600 8N1):
+
+    BAUD: 57600
+    Number of Bits: 8
+    Parity: None
+    Stop bits: 1
+
+  You will need to connect a monitor program (Hyperterminal, Tera Term,
+  minicom, whatever) to UART0/RS232_0 and configure the serial port as
+  shown above.
+
+  NOTE: The ostest example works fine at 115200, but the other configurations
+  have problems at that rate (probably because they use the interrupt driven
+  serial driver).  Other LPC17xx boards with the same clocking will run at
+  115200.
+
+  LCD
+  ---
+
+  The LPC1766-STK has a Nokia 6100 132x132 LCD and either a Phillips PCF8833
+  or an Epson S1D15G10 LCD controller.  The NuttX configuration may have to
+  be adjusted depending on which controller is used with the LCD.  The
+  "LPC1766-STK development board Users Manual" states tha the board features
+  a "LCD NOKIA 6610 128x128 x12bit color TFT with Epson LCD controller."
+  But, referring to a different Olimex board, "Nokia 6100 LCD Display
+  Driver," Revision 1, James P. Lynch ("Nokia 6100 LCD Display Driver.pdf")
+  says:
+  
+  "The major irritant in using this display is identifying the graphics
+   controller; there are two possibilities (Epson S1D15G00 or Philips
+   PCF8833). The LCD display sold by the German Web Shop Jelu has a Leadis
+   LDS176 controller but it is 100% compatible with the Philips PCF8833).
+   So how do you tell which controller you have? Some message boards have
+   suggested that the LCD display be disassembled and the controller chip
+   measured with a digital caliper – well that’s getting a bit extreme.
+
+  "Here’s what I know. The Olimex boards have both display controllers
+   possible; if the LCD has a GE-12 sticker on it, it’s a Philips PCF8833.
+   If it has a GE-8 sticker, it’s an Epson controller. The older Sparkfun
+   6100 displays were Epson, their web site indicates that the newer ones
+   are an Epson clone. Sparkfun software examples sometimes refer to the
+   Philips controller so the whole issue has become a bit murky. The
+   trading companies in Honk Kong have no idea what is inside the displays
+   they are selling. A Nokia 6100 display that I purchased from Hong Kong
+   a couple of weeks ago had the Philips controller."
+
+  The LCD connects to the LPC1766 via SPI and two GPIOs.  The two GPIOs are
+  noted above:
+  
+    P1.21 is the SPI chip select, and
+    P3.25 is the LCD reset
+    P3.26 is PWM1 output used to control the backlight intensity.
+  
+  MISO0 and MOSI0 are join via a 1K ohm resistor so the LCD appears to be
+  write only.
+
+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery or devkitARM toolchain, you simply need add one of the
+  following configuration options to your .config (or defconfig) file:
+
+    CONFIG_LPC17_CODESOURCERYW=y   : CodeSourcery under Windows
+    CONFIG_LPC17_CODESOURCERYL=y   : CodeSourcery under Linux
+    CONFIG_LPC17_DEVKITARM=y       : devkitARM under Windows
+    CONFIG_LPC17_BUILDROOT=y       : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_LPC17_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows)and devkitARM are Windows native toolchains.
+  The CodeSourcey (for Linux) and NuttX buildroot toolchains are Cygwin and/or
+  Linux native toolchains. There are several limitations to using a Windows based
+  toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+^^^^
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project (There is a simple RIDE project
+  in the RIDE subdirectory).
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/lpc17xx,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/lpc17x/lpc17_vectors.S.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh olimex-lpc1766stk/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you
+  are building a Cortex-M3 toolchain for Cygwin under Windows.
+
+  NOTE: This is an OABI toolchain.
+
+LEDs
+^^^^
+
+  If CONFIG_ARCH_LEDS is defined, then support for the LPC1766-STK LEDs will be
+  included in the build.  See:
+
+  - configs/olimex-lpc1766stk/include/board.h - Defines LED constants, types and
+    prototypes the LED interface functions.
+
+  - configs/olimex-lpc1766stk/src/lpc1766stk_internal.h - GPIO settings for the LEDs.
+
+  - configs/olimex-lpc1766stk/src/up_leds.c - LED control logic.
+
+  The LPC1766-STK has two LEDs.  If CONFIG_ARCH_LEDS is defined, these LEDs will
+  be controlled as follows for NuttX debug functionality (where NC means "No Change").
+  Basically,
+
+  LED1:
+  - OFF means that the OS is still initializing. Initialization is very fast so
+    if you see this at all, it probably means that the system is hanging up
+    somewhere in the initialization phases.
+  - ON means that the OS completed initialization.
+  - Glowing means that the LPC17 is running in a reduced power mode: LED1 is
+    turned off when the processor enters sleep mode and back on when it wakesup
+    up.
+
+  LED2:
+  - ON/OFF toggles means that various events are happening.
+  - GLowing: LED2 is turned on and off on every interrupt so even timer interrupts
+    should cause LED2 to glow faintly in the normal case.
+  - Flashing. If the LED2 is flashing at about 2Hz, that means that a crash
+    has occurred.  If CONFIG_ARCH_STACKDUMP=y, you will get some diagnostic
+    information on the console to help debug what happened.
+
+  NOTE:  LED2 is controlled by a jumper labeled: ACC_IRQ/LED2.  That jump must be
+  in the LED2 position in order to support LED2.
+
+  LED1    LED2      Meaning
+  ------- --------  --------------------------------------------------------------------
+   OFF    OFF      Still initializing and there is no interrupt activity. 
+                    Initialization is very fast so if you see this, it probably means
+                    that the system is hung up somewhere in the initialization phases.
+   OFF     Glowing  Still initializing (see above) but taking interrupts.
+   OFF     ON       This would mean that (1) initialization did not complete but the
+                    software is hung, perhaps in an infinite loop, somewhere inside
+                    of an interrupt handler.
+   OFF     Flashing Ooops!  We crashed before finishing initialization (or, perhaps
+                    after initialization, during an interrupt while the LPC17xx was
+                    sleeping -- see below).
+ 
+   ON      OFF      The system has completed initialization, but is apparently not taking
+                    any interrupts.
+   ON      Glowing  The OS successfully initialized and is taking interrupts (but, for
+                    some reason, is never entering a reduced power mode -- perhaps the
+                    CPU is very busy?).
+   ON      ON       This would mean that (1) the OS complete initialization, but (2)
+                    the software is hung, perhaps in an infinite loop, somewhere inside
+                    of a signal or interrupt handler.
+   Glowing Glowing  This is also a normal healthy state: The OS successfully initialized,
+                    is running in reduced power mode, but taking interrupts.  The glow
+                    is very faint and you may have to dim the lights to see that LEDs are
+                    active at all!  See note below.
+   ON      Flashing Ooops!  We crashed sometime after initialization.
+
+  NOTE: In glowing/glowing case, you get some good subjective information about the
+  behavior of your system by looking at the level of the LED glow (or better, by
+  connecting O-Scope and calculating the actual duty):
+  
+  1. The intensity of the glow is determined by the duty of LED on/off toggle --
+     as the ON period becomes larger with respect the OFF period, the LED will
+     glow more brightly.
+  2. LED2 is turned ON when entering an interrupt and turned OFF when returning from
+     the interrupt.  A brighter LED2 means that the system is spending more time in
+     interrupt handling.
+  3. LED1 is turned OFF just before the processor goes to sleep.  The processor
+     sleeps until awakened by an interrupt.  LED1 is turned back ON after the
+     processor is re-awakened -- actually after returning from the interrupt that
+     cause the processor to re-awaken (LED1 will be off during the execution of
+     that interrupt).  So a brighter LED1 means that the processor is spending
+     less time sleeping.
+
+  When my STM32 sits IDLE -- doing absolutely nothing but processing timer interrupts --
+  I see the following:
+  
+  1. LED1 glows dimly due to the timer interrupts.
+  2. But LED2 is even more dim!  The LED ON time excludes the time processing the
+     interrupt that re-awakens the processing.  So this tells me that the STM32 is
+     spending more time processing timer interrupts than doing any other kind of
+     processing.  That, of course, makes sense if the system is truly idle and only
+     processing timer interrupts.
+
+Using OpenOCD and GDB with an FT2232 JTAG emulator
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  Downloading OpenOCD
+  
+    You can get information about OpenOCD here: http://openocd.berlios.de/web/
+    and you can download it from here. http://sourceforge.net/projects/openocd/files/.
+    To get the latest OpenOCD with more mature lpc17xx, you have to download
+    from the GIT archive.
+    
+      git clone git://openocd.git.sourceforge.net/gitroot/openocd/openocd
+
+    At present, there is only the older, frozen 0.4.0 version.  These, of course,
+    may have changed since I wrote this.
+ 
+  Building OpenOCD under Cygwin:
+
+    You can build OpenOCD for Windows using the Cygwin tools.  Below are a
+    few notes that worked as of November 7, 2010.  Things may have changed
+    by the time you read this, but perhaps the following will be helpful to
+    you:
+    
+    1. Install Cygwin (http://www.cygwin.com/).  My recommendation is to install
+       everything.  There are many tools you will need and it is best just to
+       waste a little disk space and have everthing you need.  Everything will
+       require a couple of gigbytes of disk space.
+
+    2. Create a directory /home/OpenOCD.
+
+    3. Get the FT2232 drivr from http://www.ftdichip.com/Drivers/D2XX.htm and
+       extract it into /home/OpenOCD/ftd2xx
+
+       $ pwd
+       /home/OpenOCD
+       $ ls
+       CDM20802 WHQL Certified.zip
+       $ mkdir ftd2xx
+       $ cd ftd2xx
+       $ unzip ..CDM20802\ WHQL\ Certified.zip 
+       Archive:  CDM20802 WHQL Certified.zip
+       ...
+
+    3. Get the latest OpenOCD source
+    
+       $ pwd
+       /home/OpenOCD
+       $ git clone git://openocd.git.sourceforge.net/gitroot/openocd/openocd
+ 
+       You will then have the source code in /home/OpenOCD/openocd
+
+    4. Build OpenOCD for the FT22322 interface
+
+       $ pwd
+       /home/OpenOCD/openocd
+       $ ./bootstrap 
+
+       Jim is a tiny version of the Tcl scripting language.  It is needed
+       by more recent versions of OpenOCD.  Build libjim.a using the following
+       instructions:
+
+       $ git submodule init
+       $ git submodule update
+       $ cd jimtcl
+       $ ./configure --with-jim-ext=nvp
+       $ make
+       $ make install
+
+       Configure OpenOCD:
+
+       $ ./configure --enable-maintainer-mode --disable-werror --disable-shared \
+                    --enable-ft2232_ftd2xx --with-ftd2xx-win32-zipdir=/home/OpenOCD/ftd2xx \
+                    LDFLAGS="-L/home/OpenOCD/openocd/jimtcl"
+
+        Then build OpenOCD and its HTML documentation:
+
+        $ make
+        $ make html
+
+        The result of the first make will be the "openocd.exe" will be
+        created in the folder /home/openocd/src.  The following command
+        will install OpenOCD to a standard location (/usr/local/bin)
+        using using this command:
+
+        $ make install
+
+  Helper Scripts.
+
+    I have been using the Olimex ARM-USB-OCD JTAG debugger with the
+    LPC1766-STK (http://www.olimex.com).  OpenOCD requires a configuration
+    file.  I keep the one I used last here:
+    
+      configs/olimex-lpc1766stk/tools/olimex.cfg
+
+    However, the "correct" configuration script to use with OpenOCD may
+    change as the features of OpenOCD evolve.  So you should at least
+    compare that olimex.cfg file with configuration files in
+    /usr/local/share/openocd/scripts/target (or /home/OpenOCD/openocd/tcl/target).
+    As of this writing, there is no script for the lpc1766, but the
+    lpc1768 configurtion can be used after changing the flash size to
+    256Kb.  That is, change:
+
+      flash bank $_FLASHNAME lpc2000 0x0 0x80000 0 0 $_TARGETNAME ...
+
+    To:
+ 
+      flash bank $_FLASHNAME lpc2000 0x0 0x40000 0 0 $_TARGETNAME ...
+    
+    There is also a script on the tools/ directory that I use to start
+    the OpenOCD daemon on my system called oocd.sh.  That script will
+    probably require some modifications to work in another environment:
+  
+    - Possibly the value of OPENOCD_PATH and TARGET_PATH
+    - It assumes that the correct script to use is the one at
+      configs/olimex-lpc1766stk/tools/olimex.cfg
+
+  Starting OpenOCD
+
+    Then you should be able to start the OpenOCD daemon like:
+
+      configs/olimex-lpc1766stk/tools/oocd.sh $PWD
+
+    If you use the setenv.sh file, that the path to oocd.sh will be added
+    to your PATH environment variabl.  So, in that case, the command simplifies
+    to just:
+
+      oocd.sh $PWD
+
+    Where it is assumed that you are executing oocd.sh from the top-level
+    directory where NuttX is installed.  $PWD will be the path to the
+    top-level NuttX directory.
+
+  Connecting GDB
+
+    Once the OpenOCD daemon has been started, you can connect to it via
+    GDB using the following GDB command:
+
+      arm-elf-gdb
+      (gdb) target remote localhost:3333
+
+    NOTE:  The name of your GDB program may differ.  For example, with the
+    CodeSourcery toolchain, the ARM GDB would be called arm-none-eabi-gdb.
+
+    After starting GDB, you can load the NuttX ELF file:
+
+      (gdb) symbol-file nuttx
+      (gdb) load nuttx
+
+    NOTES:
+    1. Loading the symbol-file is only useful if you have built NuttX to
+       inclulde debug symbols (by setting CONFIG_DEBUG_SYMBOLS=y in the
+       .config file).
+    2. I usually have to reset, halt, and 'load nuttx' a second time.  For
+       some reason, the first time apparently does not fully program the
+       FLASH.
+    3. The MCU must be halted prior to loading code using 'mon reset'
+       as described below.
+ 
+    OpenOCD will support several special 'monitor' commands.  These
+    GDB commands will send comments to the OpenOCD monitor.  Here
+    are a couple that you will need to use:
+  
+     (gdb) monitor reset
+     (gdb) monitor halt
+
+    NOTES:
+    1. The MCU must be halted using 'mon halt' prior to loading code.
+    2. Reset will restart the processor after loading code.
+    3. The 'monitor' command can be abbreviated as just 'mon'.

+
+USB Host Configuration
+^^^^^^^^^^^^^^^^^^^^^^
+
+The NuttShell (NSH) Nucleus 2G can be modified in order to support
+USB host operations.  To make these modifications, do the following:
+
+1. First configure to build the NSH configuration from the top-level
+   NuttX directory:
+
+   cd tools
+   ./configure nucleus2g/nsh
+   cd ..
+
+2. Then edit the top-level .config file to enable USB host.  Make the
+   following changes:
+
+   CONFIG_LPC17_USBHOST=n
+   CONFIG_USBHOST=n
+   CONFIG_SCHED_WORKQUEUE=y
+
+When this change is made, NSH should be extended to support USB flash
+devices.  When a FLASH device is inserted, you should see a device
+appear in the /dev (pseudo) directory.  The device name should be
+like /dev/sda, /dev/sdb, etc.  The USB mass storage device, is present
+it can be mounted from the NSH command line like:
+
+   ls /dev
+   mount -t vfat /dev/sda /mnt/flash
+
+Files on the connect USB flash device should then be accessible under
+the mountpoint /mnt/flash.
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each Olimex LPC1766-STK configuration is maintained in a
+sudirectory and can be selected as follow:
+
+	cd tools
+	./configure.sh olimex-lpc1766stk/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  ftpc:
+    This is a simple FTP client shell used to exercise the capabilities
+    of the FTPC library (apps/netutils/ftpc).  This example is configured
+    to that it will only work as a "built-in" program that can be run from
+    NSH when CONFIG_NSH_BUILTIN_APPS is defined.
+
+    From NSH, the startup command sequence is then:
+
+      nsh> mount -t vfat /dev/mmcsd0 /tmp # Mount the SD card at /tmp
+      nsh> cd /tmp                        # cd into the /tmp directory
+      nsh> ftpc xx.xx.xx.xx[:pp]          # Start the FTP client
+      nfc> login <name> <password>        # Log into the FTP server
+      nfc> help                           # See a list of FTP commands
+
+    where xx.xx.xx.xx is the IP address of the FTP server and pp is an
+    optional port number (default is the standard FTP port number 21).
+
+    NOTES:
+
+    1. Support for FAT long file names is built-in but can easily be
+       removed if you are concerned about Microsoft patent issues (see the
+       section "FAT Long File Names" in the top-level COPYING file).
+       
+       CONFIG_FS_FAT=y
+       CONFIG_FAT_LCNAMES=y <-- Long file name support
+       CONFIG_FAT_LFN=y
+       CONFIG_FAT_MAXFNAME=32
+       CONFIG_FS_NXFFS=n
+       CONFIG_FS_ROMFS=n
+
+    2. You may also want to define the following in your configuration file.
+       Otherwise, you will have not feedback about what is going on:
+ 
+       CONFIG_DEBUG=y
+       CONFIG_DEBUG_VERBOSE=y
+       CONFIG_DEBUG_FTPC=y
+
+  hidkbd:
+    This configuration directory, performs a simple test of the USB host
+    HID keyboard class driver using the test logic in apps/examples/hidkbd.
+
+  nettest:
+    This configuration directory may be used to enable networking using the
+    LPC17xx's Ethernet controller. It uses apps/examples/nettest to excercise the
+    TCP/IP network.
+
+  nsh:
+    Configures the NuttShell (nsh) located at apps/examples/nsh.  The
+    Configuration enables both the serial and telnet NSH interfaces.
+    Support for the board's SPI-based MicroSD card is included.
+
+    NOTE:  If you start the program with no SD card inserted, there will be
+    a substantial delay. This is because there is no hardware support to sense
+    whether or not an SD card is inserted.  As a result, the driver has to
+    go through many retries and timeouts before it finally decides that there
+    is not SD card in the slot.
+
+    Configuration Notes:
+
+    1. Uses the buildroot toolchaing (CONFIG_LPC17_BUILDROOT=y).  But that is
+       easily reconfigured (see above)
+    2. Support for FAT long file names is built-in but can easily be
+       removed if you are concerned about Microsoft patent issues (see the
+       section "FAT Long File Names" in the top-level COPYING file).
+       
+        CONFIG_FS_FAT=y
+        CONFIG_FAT_LCNAMES=y <-- Long file name support
+        CONFIG_FAT_LFN=y
+        CONFIG_FAT_MAXFNAME=32
+        CONFIG_FS_NXFFS=n
+        CONFIG_FS_ROMFS=n
+
+    3. Includes logic to support a button test (apps/examples/buttons).  To
+       enable the button test, make the following changes in the .config
+       after configuring:
+
+       -CONFIG_ARCH_BUTTONS=n
+       +CONFIG_ARCH_BUTTONS=y
+
+       -CONFIG_GPIO_IRQ=n
+       -CONFIG_ARCH_IRQBUTTONS=n
+       +CONFIG_GPIO_IRQ=y
+       +CONFIG_ARCH_IRQBUTTONS=y
+
+    4. This example supports the CAN loopback test (apps/examples/can) but this
+       must be manually enabled by selecting:
+
+       CONFIG_CAN=y             : Enable the generic CAN infrastructure
+       CONFIG_LPC17_CAN1=y      : Enable CAN1
+       CONFIG_CAN_LOOPBACK=y    : Enable CAN loopback mode
+
+       See also apps/examples/README.txt
+ 
+       Special CAN-only debug options:
+
+       CONFIG_DEBUG_CAN
+       CONFIG_CAN_REGDEBUG
+
+  nx:
+    An example using the NuttX graphics system (NX).  This example uses
+    the Nokia 6100 LCD driver. NOTE:  The Nokia 6100 driver does not
+    work on this board as of this writing.
+
+  ostest:
+    This configuration directory, performs a simple OS test using
+    apps/examples/ostest.
+
+  slip-httpd:
+    This configuration is identical to the thttpd configuration except that
+    it uses the SLIP data link layer via a serial driver instead of the
+    Ethernet data link layer.  The Ethernet driver is disabled; SLIP IP
+    packets are exchanged on UART1; UART0 is still the serial console.
+
+    1. Configure and build the slip-httpd configuration.
+    2. Connect to a Linux box (assuming /dev/ttyS0)
+    3. Reset on the target side and attach SLIP on the Linux side:
+    
+       $ modprobe slip
+       $ slattach -L -p slip -s 57600 /dev/ttyS0 &
+ 
+       This should create an interface with a name like sl0, or sl1, etc.
+       Add -d to get debug output.  This will show the interface name.
+
+       NOTE: The -L option is included to suppress use of hardware flow
+       control.  This is necessary because I haven't figured out how to 
+       use the UART1 hardware flow control yet.
+
+       NOTE: The Linux slip module hard-codes its MTU size to 296.  So you
+       might as well set CONFIG_NET_BUFSIZE to 296 as well.
+
+    4. After turning over the line to the SLIP driver, you must configure
+       the network interface. Again, you do this using the standard
+       ifconfig and route commands. Assume that we have connected to a
+       host PC with address 192.168.0.101 from your target with address
+       10.0.0.2. On the Linux PC you would execute the following as root:
+
+       $ ifconfig sl0 10.0.0.1 pointopoint 10.0.0.2 up
+       $ route add 10.0.0.2 dev sl0
+
+       Assuming the SLIP is attached to device sl0.
+
+    5. For monitoring/debugging traffic:
+
+       $ tcpdump -n -nn -i sl0 -x -X -s 1500
+
+    NOTE: Only UART1 supports the hardware handshake.  If hardware
+    handshake is not available, then you might try the slattach option
+    -L which is supposed to enable "3-wire operation."
+
+    NOTE: This configurat only works with VERBOSE debug disabled.  For some
+    reason, certain debug statements hang(?).
+    
+    NOTE: This example does not use UART1's hardware flow control.  UART1
+    hardware flow control is partially implemented but does not behave as
+    expected.  It needs a little more work.
+
+  thttpd:
+    This builds the THTTPD web server example using the THTTPD and
+    the apps/examples/thttpd application.
+
+  usbserial:
+    This configuration directory exercises the USB serial class
+    driver at apps/examples/usbserial.  See apps/examples/README.txt for
+    more information.
+
+  usbstorage:
+    This configuration directory exercises the USB mass storage
+    class driver at apps/examples/usbstorage.  See apps/examples/README.txt
+    for more information.

+ *   4. The handle returned by up_spiinitialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling

+Repair procedure for ARM-USB-OCD drivers
+
+1.   Uninstalling ARM-USB-OCD drivers
+-------------------------------------
+1.1. Connect your programmer/debugger to your computer, open Device Manager
+     and uninstall the drivers for ARM-USB-OCD.
+1.2. After you have uninstalled ARM-USB-TINY driver from Device Manager,
+     disconnect the programmer from your computer.
+1.3. Now you should download FTClean.exe from here:
+     http://www.ftdichip.com/Support/Utilities/FTClean.zip.
+1.4. After download is complete extract the "*.zip" file, open folder FTClean,
+     and run FTClean.exe
+1.5. Ror VID (Hex) select "Other". And after that fill the first box with 15ba
+     and "PID (Hex)" with 0004.
+1.6. Press "Clean System" button.  Make sure that all FTDI devices are
+     disconnected. (My require administrator privileges).
+
+2. Re-installing the ARM-USB-OCD driver
+---------------------------------------
+2.1 Connect the programmer/debugger to the computer.
+2.2 When prompted, browse to the C:\gccfd\DRIVERS\ARM-USB-OCD-DRIVER
+    directory and install. (A different driver is required for OpenOCD
+    0.4.0.  That driver is available from the olimex.com web site).

+
+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The NuttX buildroot Toolchain (see below).
+  2. The CodeSourcery GNU toolchain,
+  3. The devkitARM GNU toolchain, or
+
+  All testing has been conducted using the NuttX buildroot toolchain.  To use
+  the CodeSourcery or devkitARM GNU toolchain, you simply need to build the
+  system as follows:
+
+     make                         # Will build for the NuttX buildroot toolchain
+     make CROSSDEV=arm-eabi-      # Will build for the devkitARM toolchain
+     make CROSSDEV=arm-none-eabi- # Will build for the CodeSourcery toolchain
+     make CROSSDEV=arm-elf-       # Will build for the NuttX buildroot toolchain
+
+  Of course, hard coding this CROSS_COMPILE value in Make.defs file will save
+  some repetitive typing.
+
+  NOTE: the CodeSourcery and devkitARM toolchains are Windows native toolchains.
+  The NuttX buildroot toolchain is a Cygwin toolchain.  There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context; make CROSSDEV=arm-none-eabi-
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the CodeSourcery toolchain.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) may not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the ARM toolchain (if
+  different from the default).
+
+  If you have no ARM toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+
+  1. You must have already configured Nuttx in <some-dir>nuttx.
+
+     cd tools
+     ./configure.sh olimex-strp711/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/arm-defconfig .config
+     or
+     cp configs/arm7tdmi-defconfig-4.3.3 .config  (Last tested with this toolchain)
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h so that the PATH variable includes the path to the
+     newly built binaries.
+
+Linux OpenOCD with Wiggler JTAG
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For a debug environment, I am using OpenOCD with a Wiggler-clone JTAG interface.  The
+following steps worked for me with a 20081028 OpenOCD snapshot.
+
+GENERAL STEPS:
+
+1. Check out OpenOCD
+
+    svn checkout svn://svn.berlios.de/openocd/trunk openocd
+
+2. Build OpenOCD
+
+  Read the INSTALL file from the files you just downloaded.  You probably just need
+  to run:
+
+    ./bootstrap
+
+  Then configure OpenOCD using the configure script created by ./bootstrap.
+
+    ./configure --enable-parport
+
+  Build OpenOCD with:
+
+    make
+
+  Install OpenOCD.  Since we used the default configuration the code will be
+  installed at /usr/local/bin/openocd. Other files will be installed at
+  /usr/local/lib/openocd (configuration files, scripts, etc.) and /usr/local/share/info
+  (online documentation accessable via 'info openocd').  You need root priviledges
+  to do the following:
+
+    make install.
+
+3. Setup
+
+  OpenOCD reads its configuration from the file openocd.cfg in the current directory
+  when started.  You have two different options:
+
+  * Create a symbolic link named openocd.cfg to one of the configuration files in
+    /usr/local/lib/openocd, or
+
+  * Use a custom configuration file specified with the ‘-f <conf.file>’ command line
+    switch opeion when starting OpenOCD.
+
+  For the STR-P711, I have included bash scripts in the scripts sub-directory.
+
+4. Running OpenOCD
+
+  Make sure the ARM7TDMI board is powered and the JTAG cable is connected
+
+  Run 'src/openocd -d' (might be required to be root) and check for any errors
+  reported. The '-d' option enables debugging info.
+
+5. Telnet interface
+
+  telnet into port 4444 to get a command interface: 'telnet localhost 4444'
+
+6. GDB
+
+  start arm-elf-gdb
+  type 'file <executable.elf>' to load the executable
+  type 'set debug remote 1' to enable tracing of gdb protocol (if required)
+  type 'target remote localhost:3333' to connect to the target
+  The same commands from the telnet interface can now be accessed through the
+  'monitor' command, e.g. 'monitor help'
+
+Windows OpenOCD will Olimex JTAG
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  I have been using the Olimex ARM-USB-OCD JTAG debugger with the STR-P711
+  (http://www.olimex.com).  The OpenOCD configuration file is here:
+  scripts/oocd_ft2xx.cfg.  There is also a script on the scripts/ directory that
+  I used to start the OpenOCD daemon on my system called oocd.sh.  That
+  script would probably require some modifications to work in another
+  environment:
+  
+    - possibly the value of OPENOCD_PATH
+    - If you are working under Linux you will need to change any
+      occurances of `cygpath -w blablabla` to just blablabla
+
+  The setenv.sh file includes some environment varialble settings
+  that are needed by oocd.sh.  If you have $PATH and other environment
+  variables set up, then you should be able to start the OpenOCD daemon like:
+
+    oocd.sh
+
+  To use the Windows Olimex USB JTAG (or 'oocd.sh pp' to use the Wriggler
+  JTAG) where it is assumed that you are executing oocd.sh from the top level
+  level NuttX directory.
+
+  Once the OpenOCD daemon has been started, you can connect to it via
+  GDB using the following GDB command:
+
+   arm-elf-gdb
+   (gdb) target remote localhost:3333
+
+  And you can load the NuttX ELF file into FLASH:
+
+   (gdb) load nuttx
+
+  (There are also some files in the scripts/ directory that I used to
+  get OpenOCD working with a Wriggler clone... I never got that stuff
+  working).
+
+MMC/SD Slot
+^^^^^^^^^^^
+
+  STR-P711 PIN MMC/SD USAGE     PIN CONFIGURATION
+  ------------ ---------------- -----------------------

+  P1.15/HTXD   13/15 CP         P1.15 input
+
+  Use of SPI1 doesn't conflict with anything.  WP conflicts USB; CP conflicts
+  with NTXD. 
+
+ENC28J60 Module
+^^^^^^^^^^^^^^^
+
+  The ENC28J60 module does not come on the Olimex-STR-P711, but this describes
+  how I have connected it.  NOTE that the ENC28J60 requires an external interrupt
+  (XTI) pin.  The only easily accessible XTI pins are on SPI0/1 so you can't have
+  both SPI0 and 1 together with this configuration.
+
+  Module CON5     QFN ENC2860 Description
+  --------------- -------------------------------------------------------
+  1  J8-1 NET CS   5  ~CS    Chip select input pin for SPI interface (active low)
+  2     2 SCK      4  SCK    Clock in pin for SPI interface
+  3     3 MOSI     3  SI     Data in pin for SPI interface
+  4     4 MISO     2  SO     Data out pin for SPI interface
+  5     5 GND      -- ---    ---
+  10 J9-1 3V3      -- ---    ---
+  9     2 WOL      1  ~WOL   Unicast WOL filter

+  7     4 CLKOUT   27 CLKOUT Programmable clock output pin
+  6     5 NET RST  6  ~RESET Active-low device Reset input
+
+  For the Olimex STR-P711, the ENC28J60 module is placed on SPI0 and uses
+  P0.3 for CS, P0.6 for an interrupt, and P0.4 as a reset:
+
+  Module CON5     Olimex STR-P711 Connection
+  --------------- -------------------------------------------------------
+  1  J8-1 NET CS   SPI0-2     P0.3 output P0.3/S0.SS/I1.SDA
+  2     2 SCK      SPI0-5     SCLK0       P0.2/S0.SCLK/I1.SCL
+  3     3 MOSI     SPI0-3     MOSI0       P0.0/S0.MOSI/U3.RX
+  4     4 MISO     SPI0-4     MISO0       P0.1/S0.MISO/U3.TX
+  5     5 GND      SPI0-1     GND
+  10 J9-1 3V3      SPI0-6     3.3V

+  7     4 CLKOUT   NC
+  6     5 NET RST  SPI1-4     P0.4 output P0.4/S1.MISO
+
+  UART3, I2C cannot be used with SPI0.  The GPIOs selected for the ENC28J60
+  interrupt conflict with TIM1.
+
+  NOTE:  As of this writing, the ENC28J60 does not function on the board.
+  The board just locks up when the ENC29J60 is powered.  Most likely,
+  in sufficient current is provided via USB to power both the board and
+  the ENC28J60 (And I don't have the correct wall wart to power the
+  the board).
+
+Configurations:
+---------------
+
+  nettest:
+    This configuration directory may be used to enable networking using the
+    an Microchip ENC28J60 SPI ethernet module (see above for connection to
+    STR-P711.
+
+  nsh:
+    Configures the NuttShell (nsh) located at examples/nsh.  The
+    Configuration enables both the serial and telnetd NSH interfaces.
+
+  ostest:
+    This configuration directory, performs a simple OS test using
+    examples/ostest.

+Repair procedure for ARM-USB-OCD drivers
+
+1.   Uninstalling ARM-USB-OCD drivers
+-------------------------------------
+1.1. Connect your programmer/debugger to your computer, open Device Manager
+     and uninstall the drivers for ARM-USB-OCD.
+1.2. After you have uninstalled ARM-USB-TINY driver from Device Manager,
+     disconnect the programmer from your computer.
+1.3. Now you should download FTClean.exe from here:
+     http://www.ftdichip.com/Support/Utilities/FTClean.zip.
+1.4. After download is complete extract the "*.zip" file, open folder FTClean,
+     and run FTClean.exe
+1.5. Ror VID (Hex) select "Other". And after that fill the first box with 15ba
+     and "PID (Hex)" with 0004.
+1.6. Press "Clean System" button.  Make sure that all FTDI devices are
+     disconnected. (My require administrator privileges).
+
+2. Re-installing the ARM-USB-OCD driver
+---------------------------------------
+2.1 Connect the programmer/debugger to the computer.
+2.2 When prompted, browse to the C:\gccfd\DRIVERS\ARM-USB-OCD-DRIVER
+    directory and install. (A different driver is required for OpenOCD
+    0.4.0.  That driver is available from the olimex.com web site).

+ * ENC28J60 Module
+ *
+ * The ENC28J60 module does not come on the Olimex-STR-P711, but this
+ * describes how I have connected it.  NOTE that the ENC28J60 requires an
+ * external interrupt (XTI) pin.  The only easily accessible XTI pins are on
+ * SPI0/1 so you can't have both SPI0 and 1 together with this configuration.
+ *
+ * Module CON5     QFN ENC2860 Description
+ * --------------- -------------------------------------------------------
+ * 1  J8-1 NET CS   5  ~CS    Chip select input pin for SPI interface (active low)
+ * 2     2 SCK      4  SCK    Clock in pin for SPI interface
+ * 3     3 MOSI     3  SI     Data in pin for SPI interface
+ * 4     4 MISO     2  SO     Data out pin for SPI interface
+ * 5     5 GND      -- ---    ---
+ * 10 J9-1 3V3      -- ---    ---
+ * 9     2 WOL      1  ~WOL   Unicast WOL filter
+ * 8     3 NET INT  28 ~INT   Interrupt output pin (active low)
+ * 7     4 CLKOUT   27 CLKOUT Programmable clock output pin
+ * 6     5 NET RST  6  ~RESET Active-low device Reset input
+ *
+ * For the Olimex STR-P711, the ENC28J60 module is placed on SPI0 and uses
+ * P0.3 for CS, P0.6 for an interrupt, and P0.4 as a reset:
+ *
+ * Module CON5     Olimex STR-P711 Connection

+=====================
+
+This README file discusses the port of NuttX to the PIC32MX board from
+PCB Logic Design Co.  This board features the MicroChip PIC32MX460F512L.
+The board is a very simple -- little more than a carrier for the PIC32
+MCU plus voltage regulation, debug interface, and an OTG connector.
+
+Contents

+PIC32MX460F512L Pin Out
+=======================
+
+  PIC32MX460F512L 100-Pin TQFP (USB) Pin Out.  The mapping to the pins on
+  the PCL Logic board are very simple, each pin is brought out to a connector
+  label with the PIC32MX460F512L pin number.
+
+  On board logic only manages power, crystal, and USB signals.

+Toolchains
+==========
+
+  MPLAB/C32
+  ---------
+
+  I am using the free, "Lite" version of the PIC32MX toolchain available
+  for download from the microchip.com web site.  I am using the Windows
+  version.  The MicroChip toolchain is the only toolchain currently
+  supported in these configurations, but it should be a simple matter to
+  adapt to other toolchains by modifying the Make.defs file include in
+  each configuration.
+
+  C32 Toolchain Options:
+
+    CONFIG_PIC32MX_MICROCHIPW      - MicroChip full toolchain for Windows
+    CONFIG_PIC32MX_MICROCHIPL      - MicroChip full toolchain for Linux
+    CONFIG_PIC32MX_MICROCHIPW_LITE - MicroChip "Lite" toolchain for Windows
+    CONFIG_PIC32MX_MICROCHIPL_LITE - MicroChip "Lite" toolchain for Linux
+
+  NOTE:  The "Lite" versions of the toolchain does not support C++.  Also
+  certain optimization levels are not supported by the "Lite" toolchain.
+
+  MicrochipOpen
+  -------------
+
+  An alternative, build-it-yourself toolchain is available here:
+  http://sourceforge.net/projects/microchipopen/ .  These tools were
+  last updated circa 2010.  NOTE:  C++ support still not available
+  in this toolchain.
+
+  Building MicrochipOpen (on Linux)
+
+  1) Get the build script from this location:
+
+      http://microchipopen.svn.sourceforge.net/viewvc/microchipopen/ccompiler4pic32/buildscripts/trunk/
+
+  2) Build the code using the build script, for example:
+
+      ./build.sh -b v105_freeze
+
+     This will check out the selected branch and build the tools.
+
+  3) Binaries will then be available in a subdirectory with a name something like
+     pic32-v105-freeze-20120622/install-image/bin (depending on the current data
+     and the branch that you selected.
+
+     Note that the tools will have the prefix, mypic32- so, for example, the
+     compiler will be called mypic32-gcc.
+
+  Pinguino mips-elf Toolchain
+  ---------------------------
+
+  Another option is the mips-elf toolchain used with the Pinguino project.  This
+  is a relatively current mips-elf GCC and should provide free C++ support as
+  well. This toolchain can be downloded from the Pinguino website:
+  http://wiki.pinguino.cc/index.php/Main_Page#Download . There is some general
+  information about using the Pinguino mips-elf toolchain in this thread:
+  http://tech.groups.yahoo.com/group/nuttx/message/1821
+
+  See also configs/mirtoo/README.txt.  There is an experimental (untested)
+  configuration for the Mirtoo platform in that directory.
+
+  MPLAB/C32 vs MPLABX/X32
+  -----------------------
+
+  It appears that Microchip is phasing out the MPLAB/C32 toolchain and replacing
+  it with MPLABX and XC32.  At present, the XC32 toolchain is *not* compatible
+  with the NuttX build scripts.  Here are some of the issues that I see when trying
+  to build with XC32:
+
+  1) Make.def changes:  You have to change the tool prefix:
+
+     CROSSDEV=xc32-
+
+  2) debug.ld/release.ld:  The like expect some things that are not present in
+     the current linker scripts (or are expected with different names).  Here
+     are some partial fixes:
+
+     Rename:  kseg0_progmem to kseg0_program_mem
+     Rename:  kseg1_datamem to kseg1_data_mem
+
+  Even then, there are more warnings from the linker and some undefined symbols
+  for non-NuttX code that resides in the unused Microchip libraries.  See this
+  email thread at http://tech.groups.yahoo.com/group/nuttx/message/1458 for more
+  information.  You will have to solve at least this undefined symbol problem if
+  you want to used the XC32 toolchain.
+
+  Windows Native Toolchains
+  -------------------------
+  
+  NOTE:  There are several limitations to using a Windows based toolchain in a
+  Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+Loading NuttX with PICkit2
+==========================
+
+  NOTE:  You need a PICKit3 if you plan to use the MPLAB debugger!  The PICKit2
+  can, however, still be used to load programs.  Instructions for the PICKit3
+  are similar.
+
+  Intel Hex Forma Files:
+  ----------------------
+
+    When NuttX is built it will produce two files in the top-level NuttX
+    directory:
+
+    1) nuttx - This is an ELF file, and
+    2) nuttx.hex - This is an Intel Hex format file.  This is controlled by
+       the setting CONFIG_INTELHEX_BINARY in the .config file.
+
+    The PICkit tool wants an Intel Hex format file to burn into FLASH. However,
+    there is a problem with the generated nutt.hex: The tool expects the nuttx.hex
+    file to contain physical addresses.  But the nuttx.hex file generated from the
+    top-level make will have address in the KSEG0 and KSEG1 regions.
+
+  tools/pic32mx/mkpichex:
+  ----------------------
+
+    There is a simple tool in the NuttX tools/pic32mx directory that can be
+    used to solve both issues with the nuttx.hex file.  But, first, you must
+    build the tool:
+
+      cd tools/pic32mx
+      make
+
+    Now you will have an excecutable file call mkpichex (or mkpichex.exe on
+    Cygwin).  This program will take the nutt.hex file as an input, it will
+    convert all of the KSEG0 and KSEG1 addresses to physical address, and
+    it will write the modified file, replacing the original nuttx.hex.
+
+    To use this file, you need to do the following things:
+
+      . ./setenv.sh    # Source setenv.sh.  Among other this, this script
+                       # will add the NuttX tools/pic32mx directory to your
+                       # PATH variable
+      make             # Build nuttx and nuttx.hex
+      mkpichex $PWD    # Convert addresses in nuttx.hex.  $PWD is the path
+                       # to the top-level build directory.  It is the only
+                       # required input to mkpichex.
+
+PIC32MX Configuration Options
+=============================
+
+  General Architecture Settings:
+
+    CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+     be set to:
+
+       CONFIG_ARCH=mips
+
+    CONFIG_ARCH_family - For use in C code:
+
+       CONFIG_ARCH_MIPS=y
+
+    CONFIG_ARCH_architecture - For use in C code:
+
+       CONFIG_ARCH_MIPS32=y
+
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+       CONFIG_ARCH_CHIP=pic32mx
+
+    CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+       chip:
+
+       CONFIG_ARCH_CHIP_PIC32MX460F512L=y
+
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+
+       CONFIG_ARCH_BOARD=pcblogic-pic32mx
+
+    CONFIG_ARCH_BOARD_name - For use in C code
+
+       CONFIG_ARCH_BOARD_PCBLOGICPIC32MX=y
+
+    CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+       of delay loops
+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_DRAM_SIZE - Describes the installed DRAM (CPU SRAM in this case):
+
+       CONFIG_DRAM_SIZE=(32*1024) (32Kb)
+
+       There is an additional 32Kb of SRAM in AHB SRAM banks 0 and 1.
+
+    CONFIG_DRAM_START - The start address of installed DRAM
+
+       CONFIG_DRAM_START=0xa0000000
+
+    CONFIG_ARCH_IRQPRIO - The PIC32MXx supports interrupt prioritization
+
+       CONFIG_ARCH_IRQPRIO=y
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+       stack. If defined, this symbol is the size of the interrupt
+       stack in bytes.  If not defined, the user task stacks will be
+       used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.

+Toolchains
+==========
+
+  MPLAB/C32
+  ---------
+
+  I am using the free, "Lite" version of the PIC32MX toolchain available
+  for download from the microchip.com web site.  I am using the Windows
+  version.  The MicroChip toolchain is the only toolchain currently
+  supported in these configurations, but it should be a simple matter to
+  adapt to other toolchains by modifying the Make.defs file include in
+  each configuration.
+
+  C32 Toolchain Options:
+
+    CONFIG_PIC32MX_MICROCHIPW      - MicroChip full toolchain for Windows
+    CONFIG_PIC32MX_MICROCHIPL      - MicroChip full toolchain for Linux
+    CONFIG_PIC32MX_MICROCHIPW_LITE - MicroChip "Lite" toolchain for Windows
+    CONFIG_PIC32MX_MICROCHIPL_LITE - MicroChip "Lite" toolchain for Linux
+
+  NOTE:  The "Lite" versions of the toolchain does not support C++.  Also
+  certain optimization levels are not supported by the "Lite" toolchain.
+
+  MicrochipOpen
+  -------------
+
+  An alternative, build-it-yourself toolchain is available here:
+  http://sourceforge.net/projects/microchipopen/ .  These tools were
+  last updated circa 2010.  NOTE:  C++ support still not available
+  in this toolchain.
+
+  Building MicrochipOpen (on Linux)
+
+  1) Get the build script from this location:
+
+      http://microchipopen.svn.sourceforge.net/viewvc/microchipopen/ccompiler4pic32/buildscripts/trunk/
+
+  2) Build the code using the build script, for example:
+
+      ./build.sh -b v105_freeze
+
+     This will check out the selected branch and build the tools.
+
+  3) Binaries will then be available in a subdirectory with a name something like
+     pic32-v105-freeze-20120622/install-image/bin (depending on the current data
+     and the branch that you selected.
+
+     Note that the tools will have the prefix, mypic32- so, for example, the
+     compiler will be called mypic32-gcc.
+
+  Pinguino mips-elf Toolchain
+  ---------------------------
+
+  Another option is the mips-elf toolchain used with the Pinguino project.  This
+  is a relatively current mips-elf GCC and should provide free C++ support as
+  well. This toolchain can be downloded from the Pinguino website:
+  http://wiki.pinguino.cc/index.php/Main_Page#Download . There is some general
+  information about using the Pinguino mips-elf toolchain in this thread:
+  http://tech.groups.yahoo.com/group/nuttx/message/1821
+
+  See also configs/mirtoo/README.txt.  There is an experimental (untested)
+  configuration for the Mirtoo platform in that directory.
+
+  MPLAB/C32 vs MPLABX/X32
+  -----------------------
+
+  It appears that Microchip is phasing out the MPLAB/C32 toolchain and replacing
+  it with MPLABX and XC32.  At present, the XC32 toolchain is *not* compatible
+  with the NuttX build scripts.  Here are some of the issues that I see when trying
+  to build with XC32:
+
+  1) Make.def changes:  You have to change the tool prefix:
+
+     CROSSDEV=xc32-
+
+  2) debug.ld/release.ld:  The like expect some things that are not present in
+     the current linker scripts (or are expected with different names).  Here
+     are some partial fixes:
+
+     Rename:  kseg0_progmem to kseg0_program_mem
+     Rename:  kseg1_datamem to kseg1_data_mem
+
+  Even then, there are more warnings from the linker and some undefined symbols
+  for non-NuttX code that resides in the unused Microchip libraries.  See this
+  email thread at http://tech.groups.yahoo.com/group/nuttx/message/1458 for more
+  information.  You will have to solve at least this undefined symbol problem if
+  you want to used the XC32 toolchain.
+
+  Windows Native Toolchains
+  -------------------------
+  
+  NOTE:  There are several limitations to using a Windows based toolchain in a
+  Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+Powering the Board
+==================
+
+  Ethernet Starter Kit:
+
+    There are two ways to supply power to the PIC32 Ethernet Starter Kit:
+
+      - USB bus power connected to USB debug connector J1.
+      - An external application board with a regulated DC power supply that
+        provides +5V can be connected to the J2 application board connector
+        that is provided on the bottom side of the board.
+
+    One green LED (D3) is provided to show that the PIC32 microcontroller
+    is powered up.
+
+  Ethernet Starter Kit with MEB:
+  
+    Power can be supplied to the Multimedia Expansion Board through the DC
+    connector located on the Multimedia Expansion Board... By connecting 
+    9-14V power supply to the DC connector, the Multimedia Expansion Board
+    and starter kit will receive the proper voltages. The user can also
+    supply power via the starter kit. However, if the application uses
+    multiple features of the Multimedia Expansion Board, it is recommended
+    to use 9-14V power supply."
+
+On Board Debug Support
+======================
+
+  The PIC32 Ethernet Starter Kit includes a PIC32MX440F512H USB microcontroller
+  that provides debugger connectivity over USB. The PIC32MX440F512H is hard-wired
+  to the PIC32 device to provide two types of protocol translation:
+
+    - I/O pins of PIC32MX440F512H to the ICSP™ pins of the PIC32
+    - I/O pins of PIC32MX440F512H to the JTAG pins of the PIC32
+
+  The PIC32 Ethernet Starter Kit currently uses the JTAG pins of the PIC32 device for
+  programming and debugging.
+
+Creating Compatible NuttX HEX files
+===================================
+
+  Intel Hex Format Files:
+  -----------------------
+
+    When NuttX is built it will produce two files in the top-level NuttX
+    directory:
+
+    1) nuttx - This is an ELF file, and
+    2) nuttx.hex - This is an Intel Hex format file.  This is controlled by
+       the setting CONFIG_INTELHEX_BINARY in the .config file.
+
+    The PICkit tool wants an Intel Hex format file to burn into FLASH. However,
+    there is a problem with the generated nutt.hex: The tool expects the nuttx.hex
+    file to contain physical addresses.  But the nuttx.hex file generated from the
+    top-level make will have address in the KSEG0 and KSEG1 regions.
+
+  tools/pic32mx/mkpichex:
+  ----------------------
+
+    There is a simple tool in the NuttX tools/pic32mx directory that can be
+    used to solve both issues with the nuttx.hex file.  But, first, you must
+    build the tool:
+
+      cd tools/pic32mx
+      make
+
+    Now you will have an excecutable file call mkpichex (or mkpichex.exe on
+    Cygwin).  This program will take the nutt.hex file as an input, it will
+    convert all of the KSEG0 and KSEG1 addresses to physical address, and
+    it will write the modified file, replacing the original nuttx.hex.
+
+    To use this file, you need to do the following things:
+
+      . ./setenv.sh    # Source setenv.sh.  Among other this, this script
+                       # will add the NuttX tools/pic32mx directory to your
+                       # PATH variable
+      make             # Build nuttx and nuttx.hex
+      mkpichex $PWD    #  Convert addresses in nuttx.hex.  $PWD is the path
+                       # to the top-level build directory.  It is the only
+                       # required input to mkpichex.
+
+Serial Console: MEB
+===================
+
+ [[Warning:  This all sounds great, but the fact is that I have not yet
+   gotten any serial UART output to work from the MEB.]]
+
+  A serial console is not required to use NuttX.  However, all of the
+  Nuttx example code in the apps/examples assumes that you have a 
+  serial console.  The Ethernet Starter Kit(even with the MEB) does not
+  have any RS-232 connector needed to drive the serial console.
+
+  Raw UART signals are available at the MEB's PICtail connector, however,
+  and can be connected to an external MAX2232 board to get a serial console.
+  The defconfig files are set up to use UART2.  So the proper connections
+  would be:

+     16    U2RX
+     18    U2TX
+     28    GND
+
+  UART1 is also brought out on the PICtail and would be connected as:

+PIC32MX Configuration Options
+=============================
+
+  General Architecture Settings:
+
+    CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+     be set to:
+
+       CONFIG_ARCH=mips
+
+    CONFIG_ARCH_family - For use in C code:
+
+       CONFIG_ARCH_MIPS=y
+
+    CONFIG_ARCH_architecture - For use in C code:
+
+       CONFIG_ARCH_MIPS32=y
+
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+       CONFIG_ARCH_CHIP=pic32mx
+
+    CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+       chip:
+
+       CONFIG_ARCH_CHIP_PIC32MX795F512L=y
+
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+
+       CONFIG_ARCH_BOARD=pic32-starterkit
+
+    CONFIG_ARCH_BOARD_name - For use in C code
+
+       CONFIG_ARCH_BOARD_PIC32_STARTERKIT=y
+
+    CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+       of delay loops
+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_DRAM_SIZE - Describes the installed DRAM (CPU SRAM in this case):
+
+       CONFIG_DRAM_SIZE=(32*1024) (32Kb)
+
+       There is an additional 32Kb of SRAM in AHB SRAM banks 0 and 1.
+
+    CONFIG_DRAM_START - The start address of installed DRAM
+
+       CONFIG_DRAM_START=0xa0000000
+
+    CONFIG_ARCH_IRQPRIO - The PIC32MXx supports interrupt prioritization
+
+       CONFIG_ARCH_IRQPRIO=y
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+       stack. If defined, this symbol is the size of the interrupt
+       stack in bytes.  If not defined, the user task stacks will be
+       used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.
+
+    PIC32MX Configuration
+
+      CONFIG_PIC32MX_MVEC - Select muli- vs. single-vectored interrupts
+
+    Individual subsystems can be enabled:
+
+       CONFIG_PIC32MX_WDT            - Watchdog timer

+Configurations
+==============
+
+Each PIC32MX configuration is maintained in a sudirectory and can be
+selected as follow:
+
+    cd tools
+    ./configure.sh pic32-starterkit/<subdir>
+    cd -
+    . ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  ostest:
+  =======
+    Description.
+    ------------
+    This configuration directory, performs a simple OS test using
+    apps/examples/ostest.
+
+    Serial Output.
+    --------------
+    The OS test produces all of its test output on the serial console.
+    This configuration has UART1 enabled as a serial console.  I have
+    been unable to get this UART work on the MEB.  But on the Expansion
+    I/O board, this maps to RX = J11 pin 41 and TX = J11 pin 43
+
+  nsh:
+  ====
+    Description.
+    ------------
+    This is the NuttShell (NSH) using the NSH startup logic at
+    apps/examples/nsh.
+
+    Serial Output.
+    --------------
+    The OS test produces all of its test output on the serial console.
+    This configuration has UART1 enabled as a serial console.  I have
+    been unable to get this UART work on the MEB.  But on the Expansion
+    I/O board, this maps to RX = J11 pin 41 and TX = J11 pin 43
+
+    USB Configuations.
+    -----------------
+    Several USB device configurations can be enabled and included
+    as NSH built-in built in functions.  
+
+    To use USB device, connect the starter kit to the host using a cable
+    with a Type-B micro-plug to the starter kit’s micro-A/B port J5, located
+    on the bottom side of the starter kit. The other end of the cable
+    must have a Type-A plug. Connect it to a USB host. Jumper JP2 should be
+    removed.
+
+    All USB device configurations require the following basic setup in
+    your NuttX configuration file to enable USB device support:
+ 
+      CONFIG_USBDEV=y         : Enable basic USB device support
+      CONFIG_PIC32MX_USBDEV=y : Enable PIC32 USB device support
+
+    examples/usbterm - This option can be enabled by uncommenting
+    the following line in the appconfig file:
+
+      CONFIGURED_APPS += examples/usbterm
+
+    And by enabling one of the USB serial devices:
+
+      CONFIG_PL2303=y         : Enable the Prolifics PL2303 emulation
+      CONFIG_CDCACM=y         : or the CDC/ACM serial driver (not both)
+
+    examples/cdcacm -  The examples/cdcacm program can be included as an 
+    function by uncommenting the following line in the appconfig file:
+    
+      CONFIGURED_APPS += examples/cdcacm
+
+    and defining the following in your .config file:
+
+      CONFIG_CDCACM=y         : Enable the CDCACM device
+
+    examples/usbstorage - There are some hooks in the appconfig file
+    to enable the USB mass storage device.  However, this device cannot
+    work until support for the SD card is also incorporated.
+
+    Networking Configuations.
+    -------------------------
+    Several Networking configurations can be enabled and included
+    as NSH built-in built in functions.  The following additional
+    configuration settings are required:
+
+      CONFIG_NET=y              : Enable networking support
+      CONFIG_PIC32MX_ETHERNET=y : Enable the PIC32 Ethernet driver
+      CONFIG_NSH_TELNET=y       : Enable the Telnet NSH console (optional)
+
+    NOTES:
+    1. This logic will assume that a network is connected.  During its
+       initialization, it will try to negotiate the link speed.  If you have
+       no network connected when you reset the board, there will be a long
+       delay (maybe 30 seconds?) before anything happens.  That is the timeout
+       before the networking finally gives up and decides that no network is
+       available.
+
+    2. This example can support an FTP client.  In order to build in FTP client
+       support simply uncomment the following lines in the appconfig file (before
+       configuring) or in the apps/.config file (after configuring):
+
+       #CONFIGURED_APPS += netutils/ftpc
+       #CONFIGURED_APPS += examples/ftpc
+
+    3. This example can support an FTP server.  In order to build in FTP server
+       support simply uncomment the following lines in the appconfig file (before
+       configuring) or in the apps/.config file (after configuring):
+
+       #CONFIGURED_APPS += netutils/ftpd
+       #CONFIGURED_APPS += examples/ftpd
+
+       And enable poll() support in the NuttX configuration file:
+
+       CONFIG_DISABLE_POLL=n
+
+  nsh2:
+  =====
+
+    This is an alternative NSH configuration.  Without the Expansion I/O board,
+    there is no way to connect a serial console.  This NSH alternative supports
+    only a Telnet console.  The nsh2 differs from the nsh configuration in the
+    following ways:
+
+    1. Networking is enabled:
+
+       CONFIG_NET=y                : Enable networking support
+       CONFIG_PIC32MX_ETHERNET=y   : Enable the PIC32 Ethernet driver
+       CONFIG_NSH_CONSOLE=n        : Disable NSH serial console
+       CONFIG_NSH_TELNET=y         : Enable the Telnet NSH console
+
+       See apps/nshlib/README.txt for other NSH networking-related configuration
+       settings.
+
+    2. UART1 is disabled
+ 
+      CONFIG_PIC32MX_UART1=n        : UART1 is disabled (as well as other UARTs)
+      CONFIG_UART1_SERIAL_CONSOLE=n : There is no serial console
+
+    3. The RAM log is enabled"
+    
+      CONFIG_SYSLOG=y             : Enables the System Logging feature.
+      CONFIG_RAMLOG=y             : Enable the RAM-based logging feature.
+      CONFIG_RAMLOG_CONSOLE=n     : (there is no default console device)
+      CONFIG_RAMLOG_SYSLOG=y      : This enables the RAM-based logger as the
+                                    system logger.
+
+      Logging is currently set up to use 16Kb of memory:
+
+      CONFIG_RAMLOG_CONSOLE_BUFSIZE=16384
+
+    There are a few other configuration differences as necessary to support
+    this different device configuration. Just the do the 'diff' if you are
+    curious.
+
+    NOTES:
+      See the notes for the nsh configuration.  Most also apply to the nsh2
+      configuration.
+
+  Using a RAM disk and the USB MSC device with nsh and nsh2
+  ---------------------------------------------------------
+  Here is an experimental change to either examples/nsh or examples/nsh2
+  that will create a RAM disk and attempt to export that RAM disk as a
+  USB mass storage device.
+
+  1. Changes to nuttx/.config
+
+    a) Enable support for the PIC32 USB device
+
+      -CONFIG_PIC32MX_USBDEV=n 
+      +CONFIG_PIC32MX_USBDEV=y
+
+    b) Enable NuttX USB device support
+
+      -CONFIG_USBDEV=n
+      +CONFIG_USBDEV=y
+
+    c) Enable the USB MSC class driver
+
+      -CONFIG_USBMSC=n
+      +CONFIG_USBMSC=y
+
+    d) Use a RAM disk (instead of an SD card) as the USB MSC logical unit:
+
+      -CONFIG_EXAMPLES_USBMSC_DEVPATH1="/dev/mmcsd0"
+      +CONFIG_EXAMPLES_USBMSC_DEVPATH1="/dev/ram0"
+
+  2. Changes to nuttx/.config.
+
+    a) Enable building of the examples/usbstorage:
+
+      -# CONFIGURED_APPS += examples/usbstorage
+      +  CONFIGURED_APPS += examples/usbstorage
+
+  3. When NSH first comes up, you must manually create the RAM disk
+     before exporting it:
+
+    a) Create a 64Kb RAM disk at /dev/ram0:
+
+      nsh> mkrd -s 512 128
+
+    b) Put a FAT file system on the RAM disk:
+  
+      nsh> mkfatfs /dev/ram0
+
+    b) Now the 'msconn' command will connect to the host and
+       export /dev/ram0 as the USB logical unit:
+
+      nsh> msconn
+
+    NOTE:  This modification should be considered experimental.  IN the
+    little testing I have done with it, it appears functional.  But the
+    logic has not been stressed and there could still be lurking issues.
+    (There is a bug associated with this configuration listed in the
+    top-level TODO list).

+ *   implementations of the select, status, and cmddata methods of the SPI interface
+ *   defined by struct spi_ops_s (see include/nuttx/spi.h). All other methods 
+ *   including up_spiinitialize()) are provided by common PIC32MX logic.  To use
+ *   this common SPI logic on your board:
+ *
+ *   1. Provide logic in pic32mx_boardinitialize() to configure SPI/SSP chip select
+ *      pins.
+ *   2. Provide pic32mx_spiNselect() and pic32mx_spiNstatus() functions
+ *      in your board-specific logic.  These functions will perform chip selection
+ *      and status operations using GPIOs in the way your board is configured.
+ *   2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
+ *      pic32mx_spiNcmddata() functions in your board-specific logic.  These
+ *      functions will perform cmd/data selection operations using GPIOs in the way
+ *      your board is configured.
+ *   3. Add a call to up_spiinitialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by up_spiinitialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling 
+ *      mmcsd_spislotinitialize(), for example, will bind the SPI driver to
+ *      the SPI MMC/SD driver).

+Toolchains
+==========
+
+  MPLAB/C32
+  ---------
+
+  I am using the free, "Lite" version of the PIC32MX toolchain available
+  for download from the microchip.com web site.  I am using the Windows
+  version.  The MicroChip toolchain is the only toolchain currently
+  supported in these configurations, but it should be a simple matter to
+  adapt to other toolchains by modifying the Make.defs file include in
+  each configuration.
+
+  C32 Toolchain Options:
+
+    CONFIG_PIC32MX_MICROCHIPW      - MicroChip full toolchain for Windows
+    CONFIG_PIC32MX_MICROCHIPL      - MicroChip full toolchain for Linux
+    CONFIG_PIC32MX_MICROCHIPW_LITE - MicroChip "Lite" toolchain for Windows
+    CONFIG_PIC32MX_MICROCHIPL_LITE - MicroChip "Lite" toolchain for Linux
+
+  NOTE:  The "Lite" versions of the toolchain does not support C++.  Also
+  certain optimization levels are not supported by the "Lite" toolchain.
+
+  MicrochipOpen
+  -------------
+
+  An alternative, build-it-yourself toolchain is available here:
+  http://sourceforge.net/projects/microchipopen/ .  These tools were
+  last updated circa 2010.  NOTE:  C++ support still not available
+  in this toolchain.
+
+  Building MicrochipOpen (on Linux)
+
+  1) Get the build script from this location:
+
+      http://microchipopen.svn.sourceforge.net/viewvc/microchipopen/ccompiler4pic32/buildscripts/trunk/
+
+  2) Build the code using the build script, for example:
+
+      ./build.sh -b v105_freeze
+
+     This will check out the selected branch and build the tools.
+
+  3) Binaries will then be available in a subdirectory with a name something like
+     pic32-v105-freeze-20120622/install-image/bin (depending on the current data
+     and the branch that you selected.
+
+     Note that the tools will have the prefix, mypic32- so, for example, the
+     compiler will be called mypic32-gcc.
+
+  Pinguino mips-elf Toolchain
+  ---------------------------
+
+  Another option is the mips-elf toolchain used with the Pinguino project.  This
+  is a relatively current mips-elf GCC and should provide free C++ support as
+  well. This toolchain can be downloded from the Pinguino website:
+  http://wiki.pinguino.cc/index.php/Main_Page#Download . There is some general
+  information about using the Pinguino mips-elf toolchain in this thread:
+  http://tech.groups.yahoo.com/group/nuttx/message/1821
+
+  See also configs/mirtoo/README.txt.  There is an experimental (untested)
+  configuration for the Mirtoo platform in that directory.
+
+  MPLAB/C32 vs MPLABX/X32
+  -----------------------
+
+  It appears that Microchip is phasing out the MPLAB/C32 toolchain and replacing
+  it with MPLABX and XC32.  At present, the XC32 toolchain is *not* compatible
+  with the NuttX build scripts.  Here are some of the issues that I see when trying
+  to build with XC32:
+
+  1) Make.def changes:  You have to change the tool prefix:
+
+     CROSSDEV=xc32-
+
+  2) debug.ld/release.ld:  The like expect some things that are not present in
+     the current linker scripts (or are expected with different names).  Here
+     are some partial fixes:
+
+     Rename:  kseg0_progmem to kseg0_program_mem
+     Rename:  kseg1_datamem to kseg1_data_mem
+
+  Even then, there are more warnings from the linker and some undefined symbols
+  for non-NuttX code that resides in the unused Microchip libraries.  See this
+  email thread at http://tech.groups.yahoo.com/group/nuttx/message/1458 for more
+  information.  You will have to solve at least this undefined symbol problem if
+  you want to used the XC32 toolchain.
+
+  Windows Native Toolchains
+  -------------------------
+  
+  NOTE:  There are several limitations to using a Windows based toolchain in a
+  Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+

+
+Creating Compatible NuttX HEX files
+===================================
+
+  Intel Hex Format Files:
+  -----------------------
+
+    When NuttX is built it will produce two files in the top-level NuttX
+    directory:
+
+    1) nuttx - This is an ELF file, and
+    2) nuttx.hex - This is an Intel Hex format file.  This is controlled by
+       the setting CONFIG_INTELHEX_BINARY in the .config file.
+
+    The PICkit tool wants an Intel Hex format file to burn into FLASH. However,
+    there is a problem with the generated nutt.hex: The tool expects the nuttx.hex
+    file to contain physical addresses.  But the nuttx.hex file generated from the
+    top-level make will have address in the KSEG0 and KSEG1 regions.
+
+  tools/pic32mx/mkpichex:
+  ----------------------
+
+    There is a simple tool in the NuttX tools/pic32mx directory that can be
+    used to solve both issues with the nuttx.hex file.  But, first, you must
+    build the tool:
+
+      cd tools/pic32mx
+      make
+
+    Now you will have an excecutable file call mkpichex (or mkpichex.exe on
+    Cygwin).  This program will take the nutt.hex file as an input, it will
+    convert all of the KSEG0 and KSEG1 addresses to physical address, and
+    it will write the modified file, replacing the original nuttx.hex.
+
+    To use this file, you need to do the following things:
+
+      . ./setenv.sh    # Source setenv.sh.  Among other this, this script
+                       # will add the NuttX tools/pic32mx directory to your
+                       # PATH variable
+      make             # Build nuttx and nuttx.hex
+      mkpichex $PWD    #  Convert addresses in nuttx.hex.  $PWD is the path
+                       # to the top-level build directory.  It is the only
+                       # required input to mkpichex.

+PIC32MX Configuration Options
+=============================
+
+  General Architecture Settings:
+
+    CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+     be set to:
+
+       CONFIG_ARCH=mips
+
+    CONFIG_ARCH_family - For use in C code:
+
+       CONFIG_ARCH_MIPS=y
+
+    CONFIG_ARCH_architecture - For use in C code:
+
+       CONFIG_ARCH_MIPS32=y
+
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+       CONFIG_ARCH_CHIP=pic32mx
+
+    CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+       chip:
+
+       CONFIG_ARCH_CHIP_PIC32MX795F512L=y
+
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+
+       CONFIG_ARCH_BOARD=pic32mx7mmb
+
+    CONFIG_ARCH_BOARD_name - For use in C code
+
+       CONFIG_ARCH_BOARD_PIC32MX7MMB=y
+
+    CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+       of delay loops
+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_DRAM_SIZE - Describes the installed DRAM (CPU SRAM in this case):
+
+       CONFIG_DRAM_SIZE=(32*1024) (32Kb)
+
+       There is an additional 32Kb of SRAM in AHB SRAM banks 0 and 1.
+
+    CONFIG_DRAM_START - The start address of installed DRAM
+
+       CONFIG_DRAM_START=0xa0000000
+
+    CONFIG_ARCH_IRQPRIO - The PIC32MXx supports interrupt prioritization
+
+       CONFIG_ARCH_IRQPRIO=y
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+       stack. If defined, this symbol is the size of the interrupt
+       stack in bytes.  If not defined, the user task stacks will be
+       used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.

+
+    USB Configurations.
+    ------------------
+    USB device support is enabled by default in this configuration.
+    The following settings are defined by default (and can be set
+    to 'n' to disabled USB device support).
+ 
+      CONFIG_USBDEV=y         : Enable basic USB device support
+      CONFIG_PIC32MX_USBDEV=y : Enable PIC32 USB device support
+      CONFIG_USBMSC=y         : USB supports a mass storage device.
+
+    In this configuration, NSH will support the following commands:
+
+      msconn  : Connect the mass storage device, exportint the SD
+                card as the USB mass storage logical unit.
+      msdis   : Disconnect the USB mass storage device
+ 
+    NOTE: The SD card should *not* be mounted under NSH *and* exported
+    by the mass storage device!!! That can result in corruption of the
+    SD card format.  This is the sequence of commands that you should
+    used to work the the SD card safely:
+
+      mount -t vfat /dev/mmcsd0 /mnt/sdcard : Mount the SD card initially
+      ...
+      umount /mnt/sdcard   : Unmount the SD card before connecting
+      msconn               : Connect the USB MSC
+      ...
+      msdis                : Disconnect the USB MSC
+      mount -t vfat /dev/mmcsd0 /mnt/sdcard : Re-mount the SD card
+      ...
+      
+    Other USB other device configurations can be enabled and
+    included as NSH built-in built in functions.

+
+      CONFIG_NSH_DHCPC=n                        : DHCP is disabled
+      CONFIG_NSH_IPADDR=(10<<24|0<<16|0<<8|2)   : Target IP address 10.0.0.2
+      CONFIG_NSH_DRIPADDR=(10<<24|0<<16|0<<8|1) : Host IP address 10.0.0.1
+
+    This will probably need to be customized for your network.
+ 
+    NOTES:
+    1. This logic will assume that a network is connected.  During its
+       initialization, it will try to negotiate the link speed.  If you have
+       no network connected when you reset the board, there will be a long
+       delay (maybe 30 seconds?) before anything happens.  That is the timeout
+       before the networking finally gives up and decides that no network is
+       available.
+
+    2. This example can support an FTP client.  In order to build in FTP client
+       support simply uncomment the following lines in the appconfig file (before
+       configuring) or in the apps/.config file (after configuring):
+
+       #CONFIGURED_APPS += netutils/ftpc
+       #CONFIGURED_APPS += examples/ftpc
+
+    3. This example can support an FTP server.  In order to build in FTP server
+       support simply uncomment the following lines in the appconfig file (before
+       configuring) or in the apps/.config file (after configuring):
+
+       #CONFIGURED_APPS += netutils/ftpd
+       #CONFIGURED_APPS += examples/ftpd
+
+       And enable poll() support in the NuttX configuration file:
+
+       CONFIG_DISABLE_POLL=n
+
+  Using a RAM disk and the USB MSC device to the nsh configuration
+  ----------------------------------------------------------------
+  Here is an experimental change to examples/nsh that will create a RAM
+  disk and attempt to export that RAM disk as a USB mass storage device.
+
+  1. Changes to nuttx/.config
+
+    a) Enable support for the PIC32 USB device
+
+      -CONFIG_PIC32MX_USBDEV=n 
+      +CONFIG_PIC32MX_USBDEV=y
+
+    b) Enable NuttX USB device support
+
+      -CONFIG_USBDEV=n
+      +CONFIG_USBDEV=y
+
+    c) Enable the USB MSC class driver
+
+      -CONFIG_USBMSC=n
+      +CONFIG_USBMSC=y
+
+    d) Use a RAM disk (instead of an SD card) as the USB MSC logical unit:
+
+      -CONFIG_EXAMPLES_USBMSC_DEVPATH1="/dev/mmcsd0"
+      +CONFIG_EXAMPLES_USBMSC_DEVPATH1="/dev/ram0"
+
+  2. Changes to nuttx/.config.
+
+    a) Enable building of the examples/usbstorage:
+
+      -# CONFIGURED_APPS += examples/usbstorage
+      +  CONFIGURED_APPS += examples/usbstorage
+
+  3. When NSH first comes up, you must manually create the RAM disk
+     before exporting it:
+
+    a) Create a 64Kb RAM disk at /dev/ram0:
+
+      nsh> mkrd -s 512 128
+
+    b) Put a FAT file system on the RAM disk:
+  
+      nsh> mkfatfs /dev/ram0
+
+    b) Now the 'msconn' command will connect to the host and
+       export /dev/ram0 as the USB logical unit:
+
+      nsh> msconn
+
+    NOTE:  This modification should be considered experimental.  IN the
+    little testing I have done with it, it appears functional.  But the
+    logic has not been stressed and there could still be lurking issues.
+    (There is a bug associated with this configuration listed in the
+    top-level TODO list).
+
+  Adding LCD and graphics support to the nsh configuration:
+  --------------------------------------------------------
+
+    LCD support is already enabled in defconfig (nuttx/.config):
+
+      CONFIG_NX=y                          : Enable graphics suppport
+      CONFIG_PIC32MX_PMP=y                 : Enable parallel port support
+      CONFIG_LCD_MIO283QT2=y               : MIO283QT2 LCD support
+
+    But you will have to enable a specific graphics example application
+    in order to see anything.
+ 
+    appconfig (apps/.config):  Enable the application configurations that you
+    want to use.  Asexamples:
+
+      CONFIGURED_APPS += examples/nx       : Pick one or more
+      CONFIGURED_APPS += examples/nxhello  :
+      CONFIGURED_APPS += examples/nximage  :
+      CONFIGURED_APPS += examples/nxlines  :
+
+  Enabling touch screen support in the nsh configuaration
+  -------------------------------------------------------
+
+    In defconfig (or nuttx/.config), set:
+
+      CONFIG_INPUT=y                       : Enable input device support
+      CONFIG_SCHED_WORKQUEUE=y             : Work queue support needed
+
+    In appconfig (or apps/.config), uncomment:
+
+      CONFIGURED_APPS += examples/touchscreen

+ * Name:  pic32mx_spiNselect, pic32mx_spiNstatus, and pic32mx_spiNcmddata

+ *   implementations of the select, status, and cmddata methods of the SPI interface
+ *   defined by struct spi_ops_s (see include/nuttx/spi.h). All other methods 
+ *   including up_spiinitialize()) are provided by common PIC32MX logic.  To use
+ *   this common SPI logic on your board:
+ *
+ *   1. Provide logic in pic32mx_boardinitialize() to configure SPI chip select
+ *      pins.
+ *   2. Provide pic32mx_spiNselect() and pic32mx_spiNstatus() functions
+ *      in your board-specific logic.  These functions will perform chip selection
+ *      and status operations using GPIOs in the way your board is configured.
+ *   2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
+ *      pic32mx_spiNcmddata() functions in your board-specific logic.  These
+ *      functions will perform cmd/data selection operations using GPIOs in the way
+ *      your board is configured.
+ *   3. Add a call to up_spiinitialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by up_spiinitialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling 
+ *      mmcsd_spislotinitialize(), for example, will bind the SPI driver to
+ *      the SPI MMC/SD driver).

+   *  can be used to detect when Vbus is high (host actively powering), or low
+   *  (host is shut down or otherwise not supplying power).  The USB firmware
+   *  can then periodically poll this I/O pin to know when it is okay to turn on
+   *  the USB module/D+/D- pull up resistor.  When designing a purely bus powered
+   *  peripheral device, it is not possible to source current on D+ or D- when the

+pjrc-8051 README
+^^^^^^^^^^^^^^^^
+
+This port uses the PJRC 87C52 development system and the SDCC toolchain.
+
+The PJRC 87C52 development system can be obtained from http://www.pjrc.com/.
+
+The SDCC toolchain is available from http://sdcc.sourceforge.net/.  All
+testing has been performed using verison 2.6.0 of the SDDC toolchain.
+
+Building the SDCC toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The SDCC toolchain is built with the standard configure/make/make install
+sequence.  However, some special actions are required to generate libraries
+compatible with this build.  First start with the usual steps
+
+  download
+  unpack
+  cd sdcc
+  ./configure
+  make
+
+But before installing, we need to apply a patch to the SDCC 2.6.0 source.
+WARNING:  This patch is specific to the particular combination of CFLAGS
+that are used in the compilation.  If you change Make.defs, then you will
+likely have to change the patch as well.
+
+  Apply sdcc-2.6.0.patch
+  cd sdcc/device/lib
+  make model-mcs51-stack-auto
+
+Then
+
+  cd sdcc
+  make install
+

+README
+======
+
+This README file describes the contents of the build configurations available
+for the NuttX QEMU i486 port.
+
+Contents
+========
+
+  * QEMU
+    - Building QEMU
+    - Cygwin Build Problems
+    - Running QEMU
+  * Toolchains
+    - Cygwin Buildroot Toolchain
+    - Buildroot Instructions
+  * FAQ
+  * Configurations
+    - ostest
+    - nsh
+
+QEMU
+====
+
+QEMU is a generic and open source machine emulator and virtualizer.  Here are
+some links (which will probably be mostly outdated by the time your read this):
+
+  Home Page:     http://wiki.qemu.org/Main_Page
+  Downloads:     http://wiki.qemu.org/Download
+  Documentation: http://wiki.qemu.org/Manual
+  Usage:         qemu -nographic -kernel nuttx.elf
+
+Building QEMU
+-------------
+
+  tar zxf qemu-0.14.0.tar.gz 
+  cd qemu-0.14.0
+  ./configure --target-list=i386-softmmu
+  make
+  make install
+
+Cygwin Build Problems
+---------------------
+
+  Error:
+ 
+    "gcc: The -mno-cygwin flag has been removed; use a mingw-targeted cross-compiler."
+
+  Workaround:
+  
+    None known.  It does not seem possible to build QEMU using the Cygwin gcc.
+    I tried editing configure.  Removing the following line will allow QEMU to
+    configure:
+  
+      QEMU_CFLAGS="-mno-cygwin $QEMU_CFLAGS"
+
+    However, it then fails later during the compilation phase.
+
+  Recommendation:
+ 
+    1. Google for "qemu windows download" and download some pre-built QEMU
+       binaries.  I found 0.14.0 here: http://dietpc.org/windows/qemu/, or
+    2. Try building QEMU with MingGW (I understand that this is difficult).
+
+  NOTE: As of this writing, I have not been successful getting ANY pre-built
+  version of QEMU to work successfully with WinXP.  The same binaries work
+  fine on Vista, however.
+
+Running QEMU
+------------
+
+  In the top-level NuttX directory:
+
+    qemu -cpu 486 -m 2 -kernel nuttx.elf -nographic
+
+  The -nographic option redirects COM1 to your console.  However, the -nographic
+  option does not work under Cygwin.  For simple testing under Cygwin, I use
+  
+    qemu -cpu 486 -m 2 -kernel nuttx.elf -serial file:test.txt
+
+  which will send COM1 output to the file test.txt.
+ 
+Toolchains
+==========
+
+  Two target environments are supported: (1) Linux and (2) Cygwin under Windows.
+  Any GCC toolchain that can produce i486 ELF binaries should work.  On Linux,
+  you can probably use the installed system gcc.  But that will not work with
+  Cygwin.  Why?  Because the Cygwin gcc (and probably the MinGW gcc as well) do
+  not produce ELF final binaries but, rather, DOS MZ executables (i.e., .exe
+  files).  Those cannot be used with QEMU.
+
+  The file */setenv.sh should be modified to point to the correct path to the
+  GCC toolchain (if different from the default in your PATH variable).
+
+Cygwin Buildroot Toolchain
+--------------------------
+
+  With Cygwin the solution is to build an i486 cross-development toolchain to
+  generate the i486 ELF files needed by QEMU.  The NuttX buildroot package will
+  create such a toolchain.
+
+  NOTE: As of this writing, none of the released buildroot packages support the
+  i486 build.  This is only available in SVN or in any any 1.10 or later buildroot
+  release.
+
+Buildroot Instructions
+----------------------
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh qemu-i486/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/i486-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you
+  run into problems building the toolchain for Cygwin under Windows.
+
+FAQ
+===
+
+Q: I get the following error message, "undefined reference to '__stack_chk_fail'"
+A: Add -fno-stack-protector to ARCHCPUFLAGS in you Make.defs file.  Switch the
+   commenting on the following two lines in the Make.defs file:
+
+   ARCHCPUFLAGS = -march=i486 -mtune=i486 -fno-builtin
+   #ARCHCPUFLAGS = -march=i486 -mtune=i486 -fno-builtin -fno-stack-protector
+
+Configurations
+==============
+
+ostest
+------
+
+  The "standard" NuttX examples/ostest configuration.  This
+  configuration may be selected as follows:
+
+    cd <nuttx-directory>/tools
+    ./configure.sh qemu-i486/ostest
+
+nsh
+---
+
+  Configures the NuttShell (nsh) located at examples/nsh.  This
+  configuration may be selected as follows:
+
+    cd <nuttx-directory>/tools
+    ./configure.sh qemu-i486/nsh

+RGMP README File
+================
+
+RGMP stands for RTOS and GPOS on Multi-Processor.  RGMP is a project for 
+running GPOS and RTOS simultaneously on multi-processor platforms. You can
+port your favorite RTOS to RGMP together with an unmodified Linux to form a
+hybrid operating system. This makes your application able to use both RTOS
+and GPOS features.
+
+See http://rgmp.sourceforge.net/wiki/index.php/Main_Page for further
+information about RGMP.
+
+The updated build instructions can be found at:
+http://rgmp.sourceforge.net/wiki/index.php/Documentation
+
+Ubuntu Build Instructions
+--------------------------
+Build requirements:
+  * x86 PC:
+  	Ubuntu 10.04, 10.10 or 11.04
+  * OMAP4430 pandaboard:
+	Ubuntu 11.04
+
+Run requirements:
+  * multi-processor x86 PC:
+	Ubuntu 10.04, 10.10 or 11.04
+  * OMAP4430 pandaboard:
+	Ubuntu 11.04
+
+1. Download RGMP from the following URL:
+
+   http://rgmp.sourceforge.net/wiki/index.php/Download
+
+   You should choose a right verion of RGMP compatible with this NuttX release.
+   Extract the tar file:
+
+   $ tar -xjvf rgmp-<RGMP-version>.tar.bz2
+
+2. Get Linux kernel header:
+
+   $ sudo apt-get install linux-headers-$(uname -r)
+
+3. Build and install RGMP:
+
+   $ cd <rgmp-dir>
+   $ ./configure
+   $ make
+   $ sudo make install
+   $ sudo /usr/rgmp/setup
+   $ exit
+
+4. Configure NuttX.  For example, for the RGMP x86 NSH configuration, do the
+   following:
+
+   $ cd <nuttx-dir>
+   $ cd tools
+   $ ./configure.sh rgmp/x86/nsh
+   $ cd ..
+
+5. Build NuttX. Get the binary image at <nuttx-dir>/kernel.img.
+
+   $ cd <nuttx-dir>
+   $ make
+
+6. Run NuttX in RGMP:
+
+   $ cd <nuttx-dir>
+   $ su
+   $ rgmp_run
+
+
+Other Linux OS Build Instruction
+--------------------------------------
+Requirements:
+  * multi-processor x86 PC
+	running Linux kernel 2.6.32, 2.6.35 or 2.6.38
+  * OMAP4430 pandaboard
+	running Linux kernel 2.6.38
+
+1. Get your running Linux kernel header under /usr/src/linux-headers-$(uname -r)
+   directory.
+
+2. Following the Ubuntu steps begin at 3. 
+
+Note: You can configure the RGMP to find Linux kernel header in a different
+      place and install RGMP to a different place. See information printed
+      by the following instruction:
+
+      $ cd <rgmp-dir>
+      $ ./configure -h
+   
+

+README
+^^^^^^
+
+This README discusses issues unique to NuttX configurations for the
+Atmel SAM3U-EK development board.
+
+Contents
+^^^^^^^^
+
+  - Development Environment
+  - GNU Toolchain Options
+  - IDEs
+  - NuttX buildroot Toolchain
+  - LEDs
+  - SAM3U-EK-specific Configuration Options
+  - Configurations
+
+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain, ok
+  4. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery, devkitARM or Raisonance GNU toolchain, you simply need to
+  add one of the following configuration options to your .config (or defconfig)
+  file:
+
+    CONFIG_SAM3U_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_SAM3U_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_SAM3U_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_SAM3U_BUILDROOT=y	  : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_SAM3U_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows), devkitARM, and Raisonance toolchains are
+  Windows native toolchains.  The CodeSourcey (for Linux) and NuttX buildroot
+  toolchains are Cygwin and/or Linux native toolchains. There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+^^^^
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project (There is a simple RIDE project
+  in the RIDE subdirectory).
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/sam3u,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/sam3u/sam3u_vectors.S.  You may need to build NuttX
+  one time from the Cygwin command line in order to obtain the pre-built
+  startup object needed by RIDE.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh sam3u-ek/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you are
+  building a Cortex-M3 toolchain for Cygwin under Windows.
+
+LEDs
+^^^^
+
+The SAM3U-EK board has four LEDs labeled LD1, LD2, LD3 and LD4 on the
+the board.  Usage of these LEDs is defined in include/board.h and src/up_leds.c.
+They are encoded as follows:
+
+	SYMBOL				Meaning		LED0*	LED1	LED2
+	-------------------	-----------------------	-------	-------	-------
+	LED_STARTED		NuttX has been started	OFF	OFF	OFF
+	LED_HEAPALLOCATE	Heap has been allocated	OFF	OFF	ON
+	LED_IRQSENABLED		Interrupts enabled	OFF	ON	OFF
+	LED_STACKCREATED	Idle stack created	OFF	ON	ON
+	LED_INIRQ		In an interrupt**	N/C	FLASH   N/C
+	LED_SIGNAL		In a signal handler***  N/C	N/C	FLASH
+	LED_ASSERTION		An assertion failed	FLASH	N/C	N/C
+	LED_PANIC		The system has crashed	FLASH	N/C	N/C
+
+  * If LED1 and LED2 are statically on, then NuttX probably failed to boot
+    and these LEDs will give you some indication of where the failure was
+ ** The normal state is LED0=OFF, LED2=ON and LED1 faintly glowing.  This faint
+    glow is because of timer interupts that result in the LED being illuminated
+    on a small proportion of the time.
+*** LED2 may also flicker normally if signals are processed.
+
+SAM3U-EK-specific Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+	   be set to:
+
+	   CONFIG_ARCH=arm
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_ARM=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_CORTEXM3=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=sam3u
+
+	CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+	   chip:
+
+	   CONFIG_ARCH_CHIP_AT91SAM3U4
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=sam3u_ek (for the SAM3U-EK development board)
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_SAM3UEK=y
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - Describes the installed DRAM (SRAM in this case):
+
+	   CONFIG_DRAM_SIZE=0x0000c000 (48Kb)
+
+	CONFIG_DRAM_START - The start address of installed DRAM
+
+	   CONFIG_DRAM_START=0x20000000
+
+	CONFIG_ARCH_IRQPRIO - The SAM3UF103Z supports interrupt prioritization
+
+	   CONFIG_ARCH_IRQPRIO=y
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	    stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.
+
+  Individual subsystems can be enabled:
+
+	CONFIG_SAM3U_DMA
+	CONFIG_SAM3U_HSMCI
+	CONFIG_SAM3U_NAND
+	CONFIG_SAM3U_SPI
+	CONFIG_SAM3U_UART
+	CONFIG_SAM3U_USART0
+	CONFIG_SAM3U_USART1
+	CONFIG_SAM3U_USART2
+	CONFIG_SAM3U_USART3
+
+  Some subsystems can be configured to operate in different ways. The drivers
+  need to know how to configure the subsystem.
+
+	CONFIG_GPIOA_IRQ
+	CONFIG_GPIOB_IRQ
+	CONFIG_GPIOC_IRQ
+	CONFIG_USART0_ISUART
+	CONFIG_USART1_ISUART
+	CONFIG_USART2_ISUART
+	CONFIG_USART3_ISUART
+
+  AT91SAM3U specific device driver settings
+
+	CONFIG_U[S]ARTn_SERIAL_CONSOLE - selects the USARTn (n=0,1,2,3) or UART
+           m (m=4,5) for the console and ttys0 (default is the USART1).
+	CONFIG_U[S]ARTn_RXBUFSIZE - Characters are buffered as received.
+	   This specific the size of the receive buffer
+	CONFIG_U[S]ARTn_TXBUFSIZE - Characters are buffered before
+	   being sent.  This specific the size of the transmit buffer
+	CONFIG_U[S]ARTn_BAUD - The configure BAUD of the UART.  Must be
+	CONFIG_U[S]ARTn_BITS - The number of bits.  Must be either 7 or 8.
+	CONFIG_U[S]ARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
+	CONFIG_U[S]ARTn_2STOP - Two stop bits
+
+  LCD Options.  Other than the standard LCD configuration options
+  (see configs/README.txt), the SAM3U-EK driver also supports:
+
+	CONFIG_LCD_PORTRAIT - Present the display in the standard 240x320
+	   "Portrait" orientation.  Default:  The display is rotated to
+	   support a 320x240 "Landscape" orientation.
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each SAM3U-EK configuration is maintained in a sudirectory and
+can be selected as follow:
+
+	cd tools
+	./configure.sh sam3u-ek/<subdir>
+	cd -
+	. ./setenv.sh
+
+Before sourcing the setenv.sh file above, you should examine it and perform
+edits as necessary so that BUILDROOT_BIN is the correct path to the directory
+than holds your toolchain binaries.
+
+And then build NuttX by simply typing the following.  At the conclusion of
+the make, the nuttx binary will reside in an ELF file called, simply, nuttx.
+
+	make
+
+The <subdir> that is provided above as an argument to the tools/configure.sh
+must be is one of the following:
+
+  knsh:
+    This is identical to the nsh configuration below except that NuttX
+    is built as a kernel-mode, monolithic module and the user applications
+    are built separately.  This build requires a special make command; not
+    just 'make' but make with the following two arguments:
+
+	    make pass1 pass2
+
+    This is required because in the normal case (just 'make'), make will
+    create all dependencies then execute the pass1 and pass2 targets.  But
+    this example, pass2 depends on auto-generatd files produced during pass1.
+    This specall make command ('make pass1 pass2') will make the dependencies
+    separately for each pass.
+
+	At there end of the build, there four files will top-level build
+	directory:
+
+	nuttx_user.elf	- The pass1 ELF file
+	nuttx			- The pass2 ELF file
+	nuttx_user.hex	- The pass1 Intel HEX format file
+	nuttx.hex		- The pass2 Intel HEX file
+
+	The J-Link program will except files in .hex, .mot, .srec, and .bin
+	formats.
+
+  nsh:
+    Configures the NuttShell (nsh) located at examples/nsh.  The
+    Configuration enables both the serial and telnetd NSH interfaces.
+
+  nx:
+    Configures to use examples/nx using the HX834x LCD hardwar on
+    the SAM3U-EK development board.
+
+  ostest:
+    This configuration directory, performs a simple OS test using
+    examples/ostest.  By default, this project assumes that you are
+    using the DFU bootloader.
+
+  touchscreen:
+    This configuration implements an NSH configuratin with several
+    built-in applications.  The configuration is called touchscreen
+    because we intend to use this configuration to develop the
+    SAM3U-EK touchscreen.  However, there is no touchscreen driver
+    in place as of this writing.

+ * The LCD module gets its reset from NRST. As explained previously, this NRST is
+ * shared with the JTAG port and the push button BP1. The LCD chip select signal is
+ * connected to NCS2 (a dedicated jumper can disable it, making NCS2 available for
+ * other custom usage).
+ *
+ * The SAM3U4E communicates with the LCD through PIOB where a 16-bit parallel
+ * “8080-like” protocol data bus has to be implemented by software.
+ *
+ * LCD backlight is made of 4 white chip LEDs in parallel, driven by an AAT3194
+ * charge pump, MN4. The AAT3194 is controlled by the SAM3U4E through a single line
+ * Simple Serial Control (S2Cwire) interface, which permits to enable, disable, and
+ * set the LED drive current (LED brightness control) from a 32-level logarithmic
+ * scale. Four resistors R93/R94/R95/R96 are implemented for optional current
+ * limitation.
+ *
+ * The LCD module integrates a 4-wire touch screen panel controlled by
+ * MN5, ADS7843, which is a slave device on the SAM3U4E SPI bus. The ADS7843 touch
+ * ADC auxiliary inputs IN3/IN4 are connected to test points for optional function
+ * extension.

+ *     manage the board-specific aspects of the unique SAM3U chip select

+ *     (see include/nuttx/spi.h). All other methods including
+ *     up_spiinitialize()) are provided by common SAM3U logic.
+ *
+ *  To use this common SPI logic on your board:
+ *
+ *   1. Provide logic in sam3u_boardinitialize() to configure SPI chip select
+ *      pins.
+ *   2. Provide sam3u_spicsnumber(), sam3u_spiselect() and sam3u_spistatus()
+ *      functions in your board-specific logic.  These functions will perform
+ *      chip selection and status operations using GPIOs in the way your board
+ *      is configured.
+ *   2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
+ *      sam3u_spicmddata() functions in your board-specific logic.  This
+ *      function will perform cmd/data selection operations using GPIOs in
+ *      the way your board is configured.
+ *   3. Add a call to up_spiinitialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by up_spiinitialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling 
+ *      mmcsd_spislotinitialize(), for example, will bind the SPI driver to

+Development Environment
+=======================
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment because the development tools that I used only work under Windows.
+
+GNU Toolchain Options
+=====================
+
+  Toolchain Configurations
+  ------------------------
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The Atollic Toolchain,
+  3. The devkitARM GNU toolchain,
+  4. Raisonance GNU toolchain, or
+  5. The NuttX buildroot Toolchain (see below).
+
+  Most testing has been conducted using the CodeSourcery toolchain for Windows and
+  that is the default toolchain in most configurations.  To use the Atollic,
+  devkitARM, Raisonance GNU, or NuttX buildroot toolchain, you simply need to
+  add one of the following configuration options to your .config (or defconfig)
+  file:
+
+    CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_STM32_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_STM32_ATOLLIC_LITE=y   : The free, "Lite" version of Atollic toolchain under Windows
+    CONFIG_STM32_ATOLLIC_PRO=y    : The paid, "Pro" version of Atollic toolchain under Windows
+    CONFIG_STM32_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_STM32_RAISONANCE=y     : Raisonance RIDE7 under Windows
+    CONFIG_STM32_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin (default)
+
+  If you change the default toolchain, then you may also have to modify the PATH in
+  the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows), Atollic, devkitARM, and Raisonance toolchains are
+  Windows native toolchains.  The CodeSourcery (for Linux) and NuttX buildroot
+  toolchains are Cygwin and/or Linux native toolchains. There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  The CodeSourcery Toolchain (2009q1)
+  -----------------------------------
+  The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  The Atollic "Pro" and "Lite" Toolchain
+  --------------------------------------
+  One problem that I had with the Atollic toolchains is that the provide a gcc.exe
+  and g++.exe in the same bin/ file as their ARM binaries.  If the Atollic bin/ path
+  appears in your PATH variable before /usr/bin, then you will get the wrong gcc
+  when you try to build host executables.  This will cause to strange, uninterpretable
+  errors build some host binaries in tools/ when you first make.
+
+  The Atollic "Lite" Toolchain
+  ----------------------------
+  The free, "Lite" version of the Atollic toolchain does not support C++ nor
+  does it support ar, nm, objdump, or objdcopy. If you use the Atollic "Lite"
+  toolchain, you will have to set:
+
+    CONFIG_HAVE_CXX=n
+
+  In order to compile successfully.  Otherwise, you will get errors like:
+
+    "C++ Compiler only available in TrueSTUDIO Professional"
+
+  The make may then fail in some of the post link processing because of some of
+  the other missing tools.  The Make.defs file replaces the ar and nm with
+  the default system x86 tool versions and these seem to work okay.  Disable all
+  of the following to avoid using objcopy:
+
+    CONFIG_RRLOAD_BINARY=n
+    CONFIG_INTELHEX_BINARY=n
+    CONFIG_MOTOROLA_SREC=n
+    CONFIG_RAW_BINARY=n
+
+  devkitARM
+  ---------
+  The devkitARM toolchain includes a version of MSYS make.  Make sure that the
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+====
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project.
+
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/stm32,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/stm32/stm32_vectors.S.  With RIDE, I have to build NuttX
+  one time from the Cygwin command line in order to obtain the pre-built
+  startup object needed by RIDE.
+
+NuttX buildroot Toolchain
+=========================
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh shenzhou/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you are
+  building a Cortex-M3 toolchain for Cygwin under Windows.
+
+LEDs
+====
+
+The Shenzhou board has four LEDs labeled LED1, LED2, LED3 and LED4 on the
+board. These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
+defined.  In that case, the usage by the board port is defined in
+include/board.h and src/up_leds.c. The LEDs are used to encode OS-related
+events as follows:
+
+    SYMBOL               Meaning                 LED1*   LED2    LED3    LED4****
+    -------------------  ----------------------- ------- ------- ------- ------
+    LED_STARTED          NuttX has been started  ON      OFF     OFF     OFF
+    LED_HEAPALLOCATE     Heap has been allocated OFF     ON      OFF     OFF
+    LED_IRQSENABLED      Interrupts enabled      ON      ON      OFF     OFF
+    LED_STACKCREATED     Idle stack created      OFF     OFF     ON      OFF
+    LED_INIRQ            In an interrupt**       ON      N/C     N/C     OFF
+    LED_SIGNAL           In a signal handler***  N/C     ON      N/C     OFF
+    LED_ASSERTION        An assertion failed     ON      ON      N/C     OFF
+    LED_PANIC            The system has crashed  N/C     N/C     N/C     ON
+    LED_IDLE             STM32 is is sleep mode  (Optional, not used)
+
+   * If LED1, LED2, LED3 are statically on, then NuttX probably failed to boot
+     and these LEDs will give you some indication of where the failure was
+  ** The normal state is LED3 ON and LED1 faintly glowing.  This faint glow
+     is because of timer interupts that result in the LED being illuminated
+     on a small proportion of the time.
+ *** LED2 may also flicker normally if signals are processed.
+**** LED4 may not be available if RS-485 is also used it will then indicate
+     the RS-485 direction.
+
+Shenzhou-specific Configuration Options
+============================================
+
+    CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+       be set to:
+
+       CONFIG_ARCH=arm
+
+    CONFIG_ARCH_family - For use in C code:
+
+       CONFIG_ARCH_ARM=y
+
+    CONFIG_ARCH_architecture - For use in C code:
+
+       CONFIG_ARCH_CORTEXM3=y
+
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+       CONFIG_ARCH_CHIP=stm32
+
+    CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+       chip:
+
+       CONFIG_ARCH_CHIP_STM32F107VC=y
+
+    CONFIG_ARCH_BOARD_STM32_CUSTOM_CLOCKCONFIG - Enables special STM32 clock
+       configuration features.
+
+       CONFIG_ARCH_BOARD_STM32_CUSTOM_CLOCKCONFIG=n
+
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+
+       CONFIG_ARCH_BOARD=shenzhou (for the Shenzhou development board)
+
+    CONFIG_ARCH_BOARD_name - For use in C code
+
+       CONFIG_ARCH_BOARD_SHENZHOU=y
+
+    CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+       of delay loops
+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_DRAM_SIZE - Describes the installed DRAM (SRAM in this case):
+
+       CONFIG_DRAM_SIZE=0x00010000 (64Kb)
+
+    CONFIG_DRAM_START - The start address of installed DRAM
+
+       CONFIG_DRAM_START=0x20000000
+
+    CONFIG_STM32_CCMEXCLUDE - Exclude CCM SRAM from the HEAP
+
+    CONFIG_ARCH_IRQPRIO - The STM32107xxx supports interrupt prioritization
+
+       CONFIG_ARCH_IRQPRIO=y
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+       stack. If defined, this symbol is the size of the interrupt
+        stack in bytes.  If not defined, the user task stacks will be
+      used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.
+
+  Individual subsystems can be enabled:

+    CONFIG_STM32_SPI1
+    CONFIG_STM32_USART1
+    CONFIG_STM32_ADC1
+    CONFIG_STM32_ADC2
+
+  Timer devices may be used for different purposes.  One special purpose is
+  to generate modulated outputs for such things as motor control.  If CONFIG_STM32_TIMn
+  is defined (as above) then the following may also be defined to indicate that
+  the timer is intended to be used for pulsed output modulation, ADC conversion,
+  or DAC conversion. Note that ADC/DAC require two definition:  Not only do you have
+  to assign the timer (n) for used by the ADC or DAC, but then you also have to
+  configure which ADC or DAC (m) it is assigned to.
+
+    CONFIG_STM32_TIMn_PWM   Reserve timer n for use by PWM, n=1,..,14
+    CONFIG_STM32_TIMn_ADC   Reserve timer n for use by ADC, n=1,..,14

+    CONFIG_STM32_TIMn_DAC   Reserve timer n for use by DAC, n=1,..,14
+    CONFIG_STM32_TIMn_DACm  Reserve timer n to trigger DACm, n=1,..,14, m=1,..,2
+
+  For each timer that is enabled for PWM usage, we need the following additional
+  configuration settings:
+
+    CONFIG_STM32_TIMx_CHANNEL - Specifies the timer output channel {1,..,4}
+
+  NOTE: The STM32 timers are each capable of generating different signals on
+  each of the four channels with different duty cycles.  That capability is
+  not supported by this driver:  Only one output channel per timer.
+
+  JTAG Enable settings (by default JTAG-DP and SW-DP are disabled):
+
+    CONFIG_STM32_JTAG_FULL_ENABLE - Enables full SWJ (JTAG-DP + SW-DP)
+    CONFIG_STM32_JTAG_NOJNTRST_ENABLE - Enables full SWJ (JTAG-DP + SW-DP)
+      but without JNTRST.
+    CONFIG_STM32_JTAG_SW_ENABLE - Set JTAG-DP disabled and SW-DP enabled
+
+  STM32107xxx specific device driver settings
+
+    CONFIG_U[S]ARTn_SERIAL_CONSOLE - selects the USARTn (n=1,2,3) or UART
+           m (m=4,5) for the console and ttys0 (default is the USART1).
+    CONFIG_U[S]ARTn_RXBUFSIZE - Characters are buffered as received.
+       This specific the size of the receive buffer
+    CONFIG_U[S]ARTn_TXBUFSIZE - Characters are buffered before
+       being sent.  This specific the size of the transmit buffer
+    CONFIG_U[S]ARTn_BAUD - The configure BAUD of the UART.  Must be
+    CONFIG_U[S]ARTn_BITS - The number of bits.  Must be either 7 or 8.
+    CONFIG_U[S]ARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
+    CONFIG_U[S]ARTn_2STOP - Two stop bits
+
+    CONFIG_STM32_SPI_INTERRUPTS - Select to enable interrupt driven SPI
+      support. Non-interrupt-driven, poll-waiting is recommended if the
+      interrupt rate would be to high in the interrupt driven case.
+    CONFIG_STM32_SPI_DMA - Use DMA to improve SPI transfer performance.
+      Cannot be used with CONFIG_STM32_SPI_INTERRUPT.
+

+    CONFIG_STM32_ETH100MBPS - If CONFIG_STM32_AUTONEG is not defined, then this
+      may be defined to select 100 MBps speed.  Default: 10 Mbps
+    CONFIG_STM32_PHYSR - This must be provided if CONFIG_STM32_AUTONEG is
+      defined.  The PHY status register address may diff from PHY to PHY.  This
+      configuration sets the address of the PHY status register.
+    CONFIG_STM32_PHYSR_SPEED - This must be provided if CONFIG_STM32_AUTONEG is
+      defined.  This provides bit mask indicating 10 or 100MBps speed.
+    CONFIG_STM32_PHYSR_100MBPS - This must be provided if CONFIG_STM32_AUTONEG is
+      defined.  This provides the value of the speed bit(s) indicating 100MBps speed.
+    CONFIG_STM32_PHYSR_MODE - This must be provided if CONFIG_STM32_AUTONEG is
+      defined.  This provide bit mask indicating full or half duplex modes.
+    CONFIG_STM32_PHYSR_FULLDUPLEX - This must be provided if CONFIG_STM32_AUTONEG is
+      defined.  This provides the value of the mode bits indicating full duplex mode.
+    CONFIG_STM32_ETH_PTP - Precision Time Protocol (PTP).  Not supported
+      but some hooks are indicated with this condition.
+
+  Shenzhou CAN Configuration

+      mode for testing. The STM32 CAN driver does support loopback mode.
+    CONFIG_CAN1_BAUD - CAN1 BAUD rate.  Required if CONFIG_STM32_CAN1 is defined.
+    CONFIG_CAN2_BAUD - CAN1 BAUD rate.  Required if CONFIG_STM32_CAN2 is defined.

+    CONFIG_CAN_TSEG2 - the number of CAN time quanta in segment 2. Default: 7
+    CONFIG_CAN_REGDEBUG - If CONFIG_DEBUG is set, this will generate an
+      dump of all CAN registers.
+
+  Shenzhou LCD Hardware Configuration
+
+  The LCD driver supports the following LCDs on the STM324xG_EVAL board:
+
+    AM-240320L8TNQW00H (LCD_ILI9320 or LCD_ILI9321) OR
+    AM-240320D5TOQW01H (LCD_ILI9325)
+
+  Configuration options.
+
+    CONFIG_LCD_LANDSCAPE - Define for 320x240 display "landscape"
+      support. Default is this 320x240 "landscape" orientation
+      For the Shenzhou board, the edge opposite from the row of buttons
+      is used as the top of the display in this orientation.
+    CONFIG_LCD_RLANDSCAPE - Define for 320x240 display "reverse
+      landscape" support. Default is this 320x240 "landscape"
+      orientation
+      For the Shenzhou board, the edge next to the row of buttons
+      is used as the top of the display in this orientation.
+    CONFIG_LCD_PORTRAIT - Define for 240x320 display "portrait"
+      orientation support.
+    CONFIG_LCD_RPORTRAIT - Define for 240x320 display "reverse
+      portrait" orientation support.
+    CONFIG_LCD_RDSHIFT - When reading 16-bit gram data, there appears
+      to be a shift in the returned data.  This value fixes the offset.
+      Default 5.
+
+    The LCD driver dynamically selects the LCD based on the reported LCD
+    ID value.  However, code size can be reduced by suppressing support for
+    individual LCDs using:
+
+    CONFIG_STM32_ILI9320_DISABLE (includes ILI9321)
+    CONFIG_STM32_ILI9325_DISABLE
+
+  STM32 USB OTG FS Host Driver Support
+
+  Pre-requisites
+ 
+   CONFIG_USBHOST         - Enable USB host support
+   CONFIG_STM32_OTGFS     - Enable the STM32 USB OTG FS block
+   CONFIG_STM32_SYSCFG    - Needed
+   CONFIG_SCHED_WORKQUEUE - Worker thread support is required
+ 
+  Options:
+ 
+   CONFIG_STM32_OTGFS_RXFIFO_SIZE - Size of the RX FIFO in 32-bit words.
+     Default 128 (512 bytes)
+   CONFIG_STM32_OTGFS_NPTXFIFO_SIZE - Size of the non-periodic Tx FIFO
+     in 32-bit words.  Default 96 (384 bytes)
+   CONFIG_STM32_OTGFS_PTXFIFO_SIZE - Size of the periodic Tx FIFO in 32-bit
+     words.  Default 96 (384 bytes)
+   CONFIG_STM32_OTGFS_DESCSIZE - Maximum size of a descriptor.  Default: 128
+   CONFIG_STM32_OTGFS_SOFINTR - Enable SOF interrupts.  Why would you ever
+     want to do that?
+   CONFIG_STM32_USBHOST_REGDEBUG - Enable very low-level register access
+     debug.  Depends on CONFIG_DEBUG.
+   CONFIG_STM32_USBHOST_PKTDUMP - Dump all incoming and outgoing USB
+     packets. Depends on CONFIG_DEBUG.
+
+Configurations
+==============
+
+Each Shenzhou configuration is maintained in a sudirectory and
+can be selected as follow:
+
+    cd tools
+    ./configure.sh shenzhou/<subdir>
+    cd -
+    . ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  nsh:
+  ---
+    Configures the NuttShell (nsh) located at apps/examples/nsh.  The
+    Configuration enables both the serial and telnet NSH interfaces.
+
+    CONFIG_STM32_CODESOURCERYW=y              : CodeSourcery under Windows
+    CONFIG_NSH_DHCPC=n                        : DHCP is disabled
+    CONFIG_NSH_IPADDR=0x0a000002              : Target IP address 10.0.0.2
+    CONFIG_NSH_DRIPADDR=0x0a000001            : Host IP address 10.0.0.1
+
+    NOTES:
+    1. This example assumes that a network is connected.  During its
+       initialization, it will try to negotiate the link speed.  If you have
+       no network connected when you reset the board, there will be a long
+       delay (maybe 30 seconds?) before anything happens.  That is the timeout
+       before the networking finally gives up and decides that no network is
+       available.

+ *      board-specific logic.  These functions will perform chip selection and
+ *      status operations using GPIOs in the way your board is configured.
+ *   3. Add a calls to up_spiinitialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by up_spiinitialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling

+Repair procedure for ARM-USB-OCD drivers
+
+1.   Uninstalling ARM-USB-OCD drivers
+-------------------------------------
+1.1. Connect your programmer/debugger to your computer, open Device Manager
+     and uninstall the drivers for ARM-USB-OCD.
+1.2. After you have uninstalled ARM-USB-TINY driver from Device Manager,
+     disconnect the programmer from your computer.
+1.3. Now you should download FTClean.exe from here:
+     http://www.ftdichip.com/Support/Utilities/FTClean.zip.
+1.4. After download is complete extract the "*.zip" file, open folder FTClean,
+     and run FTClean.exe
+1.5. Ror VID (Hex) select "Other". And after that fill the first box with 15ba
+     and "PID (Hex)" with 0004.
+1.6. Press "Clean System" button.  Make sure that all FTDI devices are
+     disconnected. (My require administrator privileges).
+
+2. Re-installing the ARM-USB-OCD driver
+---------------------------------------
+2.1 Connect the programmer/debugger to the computer.
+2.2 When prompted, browse to the C:\gccfd\DRIVERS\ARM-USB-OCD-DRIVER
+    directory and install. (A different driver is required for OpenOCD
+    0.4.0.  That driver is available from the olimex.com web site).

+Overview
+^^^^^^^^
+
+Description
+-----------
+This README file describes the contents of the build configurations available
+for the NuttX "sim" target.  The sim target is a NuttX port that runs as a
+user-space program under Linux or Cygwin.  It is a very "low fidelity" embedded
+system simulation: This environment does not support any kind of asynchonous
+events -- there are nothing like interrupts in this context.  Therefore, there
+can be no pre-empting events.
+
+Fake Interrupts
+---------------
+In order to get timed behavior, the system timer "interrupt handler" is called
+from the sim target's IDLE loop.  The IDLE runs whenever there is no other task
+running.  So, for example, if a task calls sleep(), then that task will suspend
+wanting for the time to elapse.  If nothing else is available to run, then the
+IDLE loop runs and the timer increments, eventually re-awakening the sleeping task.
+
+Context switching is based on logic similar to setjmp() and longjmp().
+
+The sim target is used primarily as a development and test platform for new
+RTOS features.  It is also of academic interest.  But it has no real-world
+application that I know of.
+
+Timing Fidelity
+---------------
+NOTE:  In order to facility fast testing, the sim target's IDLE loop, by default,
+calls the system "interrupt handler" as fast as possible.  As a result, there
+really are no noticeable delays when a task sleeps.  However, the task really does
+sleep -- but the time scale is wrong.  If you want behavior that is closer to
+normal timing, then you can define CONFIG_SIM_WALLTIME=y in your configuration
+file.  This configuration setting will cause the sim target's IDLE loop to delay
+on each call so that the system "timer interrupt" is called at a rate approximately
+correct for the system timer tick rate.  With this definition in the configuration,
+sleep() behavior is more or less normal.
+
+Debugging
+^^^^^^^^^
+One of the best reasons to use the simulation is that is supports great, Linux-
+based debugging.  Here are the steps that I following to use the Linux ddd
+graphical front-end to GDB:
+
+1. Modify the top-level configuration file.  Enable debug symbols by defining
+   the following.
+
+   cd <NuttX-Directory>
+   CONFIG_DEBUG_SYMBOLS=y
+
+2. Re-build:
+
+   cd <NuttX-Directory>
+   make clean
+   make
+
+3. Then start the debugging:
+
+   ddd nuttx &
+   gdb> b user_start
+   gdb> r
+
+NOTE:  This above steps work fine on both Linux and Cygwin.  On Cygwin, you
+will need to start the Cywin-X server before running ddd.
+
+Issues
+^^^^^^
+
+64-Bit Issues
+-------------
+As mentioned above, context switching is based on logic like setjmp and longjmp.
+This context switching is only available for 32-bit targets.  On 64-bit machines,
+this context switching will fail.
+
+There are other 64-bit issues as well.  For example, addresses are retained in
+32-bit unsigned integer types in a few places.  On a 64-bit machine, the 32-bit
+address storage may correcupt 64-bit addressing.  NOTE:  This is really a bug --
+addresses should not be retained in uint32_t types but rather in uintptr_t types
+to avoid issues just like this.
+
+The workaround on 64-bit machines for now is to build for a 32-bit target on the
+64-bit machine.  The workaround for this issue has been included in NuttX 6.15 and
+beyond.  For thoses versions, you must add CONFIG_SIM_M32=y to the .config file in
+order to enable building a 32-bit image on a 64-bit platform.
+
+For older versions of NuttX, a patch also exists.  The patch the Make.defs file in the
+appropriate places so that -m32 is included in the CFLAGS and -m32 and -melf_386
+are included in the LDFLAGS. See the patch
+0001-Quick-hacks-to-build-sim-nsh-ostest-on-x86_64-as-32-.patch that can be found at
+http://tech.groups.yahoo.com/group/nuttx/files.
+
+Compiler differences
+--------------------
+
+operator new:
+
+  Problem:     "'operator new' takes size_t ('...') as first parameter"
+  Workaround:   Add -fpermissive to the compilation flags
+
+Continue up_setjmp() issues:
+
+  With some newer compilers, I am now getting segmentation faults in
+  up_setjmp.S (even when built with the -m32 option).  I have not looked into
+  this yet.
+
+Stack Size Issues
+-----------------
+When you run the NuttX simulation, it uses stacks allocated by NuttX from the
+NuttX heap.  The memory management model is exactly the same in the simulation
+as it is real, target system.  This is good because this produces a higher
+fidelity simulation.
+
+However, when the simulation calls into Linux/Cygwin libraries, it will still
+use these small simulation stacks.  This happens, for example, when you call
+into the system to get and put characters to the console window or when you
+make x11 calls into the system.  The programming model within those libraries
+will assume a Linux/Cygwin environment where the stack size grows dynamically
+and not the small, limited stacks of a deeply embedded system.
+
+As a consequence, those system libraries may allocate large data structures
+on the stack and overflow the small NuttX stacks.  X11, in particular,
+requires large stacks.  If you are using X11 in the simulation, make sure
+that you set aside a "lot" of stack for the X11 system calls (maybe 8 or 16Kb).
+The stack size for the thread that begins with user start is controlled
+by the configuration setting CONFIG_USERMAIN_STACKSIZE; you may need to
+increase this value to larger number to survive the X11 system calls.
+
+If you are running X11 applications as NSH add-on programs, then the stack
+size of the add-on program is controlled in another way.  Here are the
+steps for increasing the stack size in that case:
+
+  cd ../apps/namedapps  # Go to the namedapps directory
+  vi namedapps_list.h   # Edit this file and increase the stack size of the add-on
+  rm .built *.o         # This will force the namedapps logic to rebuild
+
+Buffered I/O Issues
+-------------------
+The simulated serial driver has some odd behavior.  It will stall for a long time
+on reads when the C stdio buffers are being refilled. This only effects the behavior
+of things like fgetc().  Workaround: Set CONFIG_STDIO_BUFFER_SIZE=0, suppressing
+all C buffered I/O.
+
+Networking Issues
+-----------------
+I never did get networking to work on the sim target.  It tries to use the tap device
+(/dev/net/tun) to emulate an Ethernet NIC, but I never got it correctly integrated
+with the NuttX networking (I probably should try using raw sockets instead).
+
+X11 Issues
+----------
+There is an X11-based framebuffer driver that you can use exercise the NuttX graphics
+subsystem on the simulator (see the sim/nx11 configuration below).  This may require a
+lot of tinkering to get working, depending upon where your X11 installation stores
+libraries and header files and how it names libraries.
+
+For example, on UBuntu 9.09, I had to do the following to get a clean build:
+
+    cd /usr/lib/
+    sudo ln -s libXext.so.6.4.0 libXext.so
+
+(I also get a segmentation fault at the conclusion of the NX test -- that will need
+to get looked into as well).
+
+The X11 examples builds on Cygwin, but does not run.  The last time I tried it,
+XOpenDisplay() aborted the program.  UPDATE:  This was caused by the small stack
+size and can be fixed by increasing the size of the NuttX stack that calls into
+X11.  See the discussion "Stack Size Issues" above.
+
+Configurations
+^^^^^^^^^^^^^^
+
+mount
+
+  Description
+  -----------
+  Configures to use examples/mount.  This configuration may be
+  selected as follows:
+
+    cd <nuttx-directory>/tools
+    ./configure.sh sim/mount
+
+nettest
+
+  Description
+  -----------
+  Configures to use examples/nettest.  This configuration
+  enables networking using the network TAP device.  It may
+  be selected via:
+
+    cd <nuttx-directory>/tools
+    ./configure.sh sim/nettest
+
+  NOTES:
+  - The NuttX network is not, however, functional on the Linux TAP
+    device yet.
+
+  - As of NuttX-5.18, when built on Windows, this test does not try
+    to use the TAP device (which is not available on Cygwin anyway), 
+    but inside will try to use the Cygwin WPCAP library.  Only the
+    most preliminary testing has been performed with the Cygwin WPCAP
+    library, however.
+
+    NOTE that the IP address is hard-coded in arch/sim/src/up_wpcap.c.
+    You will either need to edit your configuration files to use 10.0.0.1
+    on the "target" (CONFIG_EXAMPLE_NETTEST_*) or edit up_wpcap.c to
+    select the IP address that you want to use.
+
+nsh
+
+  Description
+  -----------
+  Configures to use the NuttShell at examples/nsh.  This configuration
+  may be selected as follows:
+
+    cd <nuttx-directory>/tools
+    ./configure.sh sim/nsh
+
+nsh2
+
+  Description
+  -----------
+  This is another example that configures to use the NuttShell at examples/nsh.
+  Unlike nsh, this version uses NSH built-in functions.  The nx, nxhello, and
+  nxlines examples are included as built-in functions.
+
+  X11 Configuration
+  -----------------
+  This configuration uses an X11-based framebuffer driver.  Of course, this
+  configuration can only be used in environments that support X11!  (And it
+  may not even be usable in all of those environments without some "tweaking"
+  See discussion below under the nx11 configuration).
+
+  Configuring
+  -----------
+  This configuration may be selected as follows:
+
+    cd <nuttx-directory>/tools
+    ./configure.sh sim/nsh2
+
+nx
+
+  Description
+  -----------
+  Configures to use examples/nx.  This configuration may be
+  selected as follows:
+
+    cd <nuttx-directory>/tools
+    ./configure.sh sim/nx
+
+  Special Framebuffer Configuration
+  ---------------------------------
+  Special simulated framebuffer configuration options:
+
+    CONFIG_SIM_FBHEIGHT - Height of the framebuffer in pixels
+    CONFIG_SIM_FBWIDTH  - Width of the framebuffer in pixels.
+    CONFIG_SIM_FBBPP    - Pixel depth in bits
+
+  No Display!
+  -----------
+  This version has NO DISPLAY and is only useful for debugging NX
+  internals in environments where X11 is not supported.  There is
+  and additonal configuration that may be added to include an X11-
+  based simulated framebuffer driver:
+  
+    CONFIG_SIM_X11FB    - Use X11 window for framebuffer
+
+  See the "nx11" configuration below for more information.
+
+  Multi- and Single-User Modes
+  ----------------------------
+  The default is the single-user NX implementation.  To select
+  the multi-user NX implementation:
+
+    CONFG_NX_MULTIUSER=y
+    CONFIG_DISABLE_MQUEUE=n
+
+nx11
+
+  Description
+  -----------
+  Configures to use examples/nx.  This configuration is similar
+  to the nx configuration except that it adds support for an X11-
+  based framebuffer driver.  Of course, this configuration can only
+  be used in environments that support X11!  (And it may not even
+  be usable in all of those environments without some "tweaking").
+  
+  This configuration may be selected as follows:
+
+    cd <nuttx-directory>/tools
+    ./configure.sh sim/nx11
+
+  Special Framebuffer Configuration
+  ---------------------------------
+  This configuration uses the same special simulated framebuffer
+  configuration options as the nx configuration:
+
+    CONFIG_SIM_X11FB    - Use X11 window for framebuffer
+    CONFIG_SIM_FBHEIGHT - Height of the framebuffer in pixels
+    CONFIG_SIM_FBWIDTH  - Width of the framebuffer in pixels.
+    CONFIG_SIM_FBBPP    - Pixel depth in bits
+
+  X11 Configuration
+  -----------------
+  But now, since CONFIG_SIM_X11FB is also selected the following
+  definitions are needed
+
+    CONFIG_SIM_FBBPP (must match the resolution of the display).
+    CONFIG_FB_CMAP=y
+
+  My system has 24-bit color, but packed into 32-bit words so
+  the correct seeting of CONFIG_SIM_FBBPP is 32.
+
+  For whatever value of CONFIG_SIM_FBBPP is selected, the
+  corresponidng CONFIG_NX_DISABLE_*BPP setting must not be
+  disabled.
+
+  Touchscreen Support
+  -------------------
+  A X11 mouse-based touchscreen simulation can also be enabled
+  by setting:
+
+    CONFIG_INPUT=y
+    CONFIG_SIM_TOUCHSCREEN=y
+
+  Then you must also have some application logic that will call
+  arch_tcinitialize(0) to register the touchscreen driver.  See
+  also configuration "touchscreen"
+
+  NOTES:
+
+  1. If you do not have the call to sim_tcinitializE(0), the build
+     will mysteriously fail claiming that is can't find up_tcenter()
+     and up_tcleave().  That is a consequence of the crazy way that
+     the simulation is built and can only be eliminated by calling
+     up_simtouchscreen(0) from your application.
+
+  2. You must first up_fbinitialize() before calling up_simtouchscreen()
+     or you will get a crash.
+
+  3. Call sim_tcuninintialize() when you are finished with the
+     simulated touchscreen.
+
+  4. Enable CONFIG_DEBUG_INPUT=y for touchscreen debug output.
+
+  X11 Build Issues
+  ----------------
+  To get the system to compile under various X11 installations
+  you may have to modify a few things.  For example, in order
+  to find libXext, I had to make the following change under
+  Ubuntu 9.09:
+
+    cd /usr/lib/
+    sudo ln -s libXext.so.6.4.0 libXext.so
+
+  Multi- and Single-User Modes
+  ----------------------------
+  The default is the single-user NX implementation.  To select
+  the multi-user NX implementation:
+
+    CONFG_NX_MULTIUSER=y
+    CONFIG_DISABLE_MQUEUE=n
+
+  examples/nxconsole
+  ------------------
+  This configuration is also set up to use the examples/nxconsole
+  test instead of examples/nx.  To enable this configuration,
+  First, select Multi-User mode as described above.  Then add the
+  following definitions to the defconfig file:
+
+    -CONFIG_NXCONSOLE=n
+    +CONFIG_NXCONSOLE=y
+
+    -CONFIG_NX_MULTIUSER=n
+    +CONFIG_NX_MULTIUSER=y
+
+  Comment out the following in the appconfig file:
+
+    -CONFIGURED_APPS += examples/nx
+    +#CONFIGURED_APPS += examples/nx
+
+  And uncomment the following:
+
+    -#CONFIGURED_APPS += examples/nxconsole
+    +CONFIGURED_APPS += examples/nxconsole
+
+  See apps/examples/README.txt for further details.
+
+nxwm
+
+  This is a special configuration setup for the NxWM window manager
+  UnitTest.  The NxWM window manager can be found here:
+
+    trunk/NxWidgets/nxwm
+
+  The NxWM unit test can be found at:
+
+    trunk/NxWidgets/UnitTests/nxwm
+
+  Documentation for installing the NxWM unit test can be found here:
+
+    trunk/NxWidgets/UnitTests/READEM.txt
+
+  NOTE:  There is an issue with running this example under the
+  simulation.  In the default configuration, this example will
+  run the NxConsole example which waits on readline() for console
+  intput.  When it calls readline(), the whole system blocks
+  waiting from input from the host OS.  So, in order to get
+  this example to run, you must comment out the readline call in
+  apps/nshlib/nsh_consolemain.c like:

+  apps/examples/touchscreen.  This test will create an empty X11 window
+  and will print the touchscreen output as it is received from the 
+  simulated touchscreen driver.  This configuration may
+  by selected as follows:
+
+    cd <nuttx-directory>/tools
+    ./configure.sh sim/touchscreen
+
+  Since this example uses the simulated frame buffer driver, the
+  most of the configuration settings discussed for the "nx11"
+  configuration also apply here.  See that discussion above.
+
+  See apps/examples/README.txt for further information about build
+  requirements and configuration settings.

+configs/skp16c26/README.txt

+^^^^^^^^^^^^^^^^^^^^^^^^^^^

+

+1. The buildroot package can be used to build an M16C toolchain.  The toolchain

+   buildroot can be downloaded from misc/buildroot in the NuttX SVN.  Insructions

+   for building the toolchain are provided below.

+

+   However, the target cannot be built because the GNU m16c-elf-ld link fails with 

+   the following message:

+

+     m32c-elf-ld: BFD (GNU Binutils) 2.19 assertion fail /home/Owner/projects/nuttx/buildroot/toolchain_build_m32c/binutils-2.19/bfd/elf32-m32c.c:482

+

+   Where the reference line is:

+

+     /* If the symbol is out of range for a 16-bit address,

+        we must have allocated a plt entry.  */

+     BFD_ASSERT (*plt_offset != (bfd_vma) -1);

+

+   No workaround is known at this time.  This is a show stopper for M16C.

+

+2. A supported version of the M16C toolchain is available here: 

+

+     http://www.kpitgnutools.com/index.php

+

+   This download is free but requires registration.  Unfortunately, this v0901 of

+   this toolchain shows the same behavior:

+

+   c:\Hew3\Tools\KPIT Cummins\GNUM16CM32C-ELF\v0901\m32c-elf\bin\m32c-elf-ld.exe: BFD (GNU Binutils) 2.19-GNUM16CM32C_v0901 assertion fail /home/kpit/fsfsrc/binutils-2.19/bfd/elf32-m32c.c:482

+

+It is possible that this error messasge my be telling me -- a very roundabout way --

+that I have exceeded the FLASH region, but I think that unlikely (it is difficult

+to know if the link does not complete gracefully).

+

+BUILDING THE R8C/M16C/M32C GNU TOOLCHAIN USING BUILDROOT

+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

+

+NOTE:  See the toolchain issues above -- you may not want to waste your time.

+

+1. CD to the correct directory.

+

+   Change to the directory just above the NuttX installation.  If <nuttx-dir> is

+   where NuttX is installed, then cd to <nuttx-dir>/..

+

+2. Get and Install the buildroot Module

+

+   a. Using a release tarball:

+

+     cd <nuttx-dir>/..

+     Download the appropriate buildroot package.

+     unpack the buildroot package

+     rename the directory to buildroot

+

+   b. Using SVN

+   

+     Check out the misc/buildroot module. SVN checkout instructions:

+

+        svn co https://nuttx.svn.sourceforge.net/svnroot/nuttx nuttx/trunk/misc/buildroot

+

+     Move the buildroot Source Tree and create the archive directory

+

+        mv misc/buildroot .

+

+   Make the archive directory:

+  

+     mkdir archive

+

+   The <nuttx-dir>/../buildroot is where the toolchain is built;

+   The <nuttx-dir>/../archive directory is where toolchain sources will be downloaded.

+

+3. Make sure that NuttX is configured

+

+     cd <nuttx-dir>/tools

+     ./configure.sh <nuttx-configuration>

+     

+4. Configure and Make the buildroot

+

+     cd buildroot

+     cp configs/m32c-defconfig-4.2.4 .config

+     make oldconfig

+     make

+

+   This will download the large source packages for the toolchain and build the toolchain.

+   The resulting binaries will be under buildroot/build_m32c.  There will also be a

+   large build directory called toolchain_build_m32c; this directory can be removed once

+   the build completes successfully.

+

+Cygwin GCC BUILD NOTES

+^^^^^^^^^^^^^^^^^^^^^^

+   On Cygwin, the buildroot 'make' command will fail with an error like:

+

+   "...

+      build/genchecksum cc1-dummy > cc1-checksum.c

+      opening cc1-dummy: No such file or directory

+   ..."

+

+   This is caused because on Cygwin, host executables will be generated with the extension .exe

+   and, apparently, the make variable "exeext" is set incorrectly.  A work around after the

+   above occurs is:

+

+      cd toolchain_build_m32c/gcc-4.2.4-initial/gcc	# Go to the directory where error occurred

+      mv cc1-dummy.exe cc1-dummy			# Rename the executable without .exe

+      rm cc1-checksum.c					# Get rid of the bad generated file

+

+   Then resume the buildroot make:

+

+      cd -						# Back to the buildroot make directory

+      make						# Restart the build

+

+   GCC is built twice.  First a initial, "bootstap" GCC is produced in

+   toolchain_build_m32c/gcc-4.2.4-initial, then the final GCC is produced in

+   toolchain_build_m32c/gcc-4.2.4-final.  The above error will occur twice:  Once for

+   the intial GCC build (see above) and once for the final GCC build. For the final GCC

+   build, the workaround is the same except that the directory will be

+   toolchain_build_m32c/gcc-4.2.4-final/gcc.

+

+
+Development Environment
+=======================
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment because the Raisonance R-Link emulatator and some RIDE7 development tools
+  were used and those tools works only under Windows.
+
+GNU Toolchain Options
+=====================
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. Raisonance GNU toolchain, or
+  4. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery, devkitARM or Raisonance GNU toolchain, you simply need to
+  add one of the following configuration options to your .config (or defconfig)
+  file:
+
+    CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_STM32_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_STM32_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_STM32_RAISONANCE=y     : Raisonance RIDE7 under Windows
+    CONFIG_STM32_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_STM32_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows), devkitARM, and Raisonance toolchains are
+  Windows native toolchains.  The CodeSourcey (for Linux) and NuttX buildroot
+  toolchains are Cygwin and/or Linux native toolchains. There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+====
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project (There is a simple RIDE project
+  in the RIDE subdirectory).
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/stm32,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/stm32/stm32_vectors.S.  With RIDE, I have to build NuttX
+  one time from the Cygwin command line in order to obtain the pre-built
+  startup object needed by RIDE.
+
+NuttX buildroot Toolchain
+=========================
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.

+
+DFU and JTAG
+============
+
+  Enbling Support for the DFU Bootloader
+  --------------------------------------
+  The linker files in these projects can be configured to indicate that you
+  will be loading code using STMicro built-in USB Device Firmware Upgrade (DFU)
+  loader or via some JTAG emulator.  You can specify the DFU bootloader by
+  adding the following line:
+
+    CONFIG_STM32_DFU=y
+
+  to your .config file. Most of the configurations in this directory are set
+  up to use the DFU loader.
+
+  If CONFIG_STM32_DFU is defined, the code will not be positioned at the beginning
+  of FLASH (0x08000000) but will be offset to 0x08003000.  This offset is needed
+  to make space for the DFU loader and 0x08003000 is where the DFU loader expects
+  to find new applications at boot time.  If you need to change that origin for some
+  other bootloader, you will need to edit the file(s) ld.script.dfu for the
+  configuration.
+
+  The DFU SE PC-based software is available from the STMicro website,
+  http://www.st.com.  General usage instructions:
+  
+  1. Convert the NuttX Intel Hex file (nuttx.hex) into a special DFU
+     file (nuttx.dfu)... see below for details.
+  2. Connect the STM3210E-EVAL board to your computer using a USB
+     cable.
+  3. Start the DFU loader on the STM3210E-EVAL board.  You do this by
+     resetting the board while holding the "Key" button.  Windows should
+     recognize that the DFU loader has been installed.
+  3. Run the DFU SE program to load nuttx.dfu into FLASH.
+
+  What if the DFU loader is not in FLASH?  The loader code is available
+  inside of the Demo dirctory of the USBLib ZIP file that can be downloaded
+  from the STMicro Website.  You can build it using RIDE (or other toolchains);
+  you will need a JTAG emulator to burn it into FLASH the first time.
+
+  In order to use STMicro's built-in DFU loader, you will have to get
+  the NuttX binary into a special format with a .dfu extension.  The
+  DFU SE PC_based software installation includes a file "DFU File Manager"
+  conversion program that a file in Intel Hex format to the special DFU
+  format.  When you successfully build NuttX, you will find a file called
+  nutt.hex in the top-level directory.  That is the file that you should
+  provide to the DFU File Manager.  You will end up with a file called
+  nuttx.dfu that you can use with the STMicro DFU SE program.
+
+  Enabling JTAG
+  -------------
+  If you are not using the DFU, then you will probably also need to enable
+  JTAG support.  By default, all JTAG support is disabled but there NuttX
+  configuration options to enable JTAG in various different ways.
+
+  These configurations effect the setting of the SWJ_CFG[2:0] bits in the AFIO
+  MAPR register.  These bits are used to configure the SWJ and trace alternate function I/Os. The SWJ (SerialWire JTAG) supports JTAG or SWD access to the
+  Cortex debug port.  The default state in this port is for all JTAG support
+  to be disable.
+
+  CONFIG_STM32_JTAG_FULL_ENABLE - sets SWJ_CFG[2:0] to 000 which enables full
+    SWJ (JTAG-DP + SW-DP)
+
+  CONFIG_STM32_JTAG_NOJNTRST_ENABLE - sets SWJ_CFG[2:0] to 001 which enable
+    full SWJ (JTAG-DP + SW-DP) but without JNTRST.
+
+  CONFIG_STM32_JTAG_SW_ENABLE - sets SWJ_CFG[2:0] to 010 which would set JTAG-DP
+    disabled and SW-DP enabled
+
+  The default setting (none of the above defined) is SWJ_CFG[2:0] set to 100
+  which disable JTAG-DP and SW-DP.
+
+OpenOCD
+=======
+
+I have also used OpenOCD with the STM3210E-EVAL.  In this case, I used
+the Olimex USB ARM OCD.  See the script in configs/stm3210e-eval/tools/oocd.sh
+for more information.  Using the script:
+
+1) Start the OpenOCD GDB server
+
+   cd <nuttx-build-directory>
+   configs/stm3210e-eval/tools/oocd.sh $PWD
+
+2) Load Nuttx
+
+   cd <nuttx-built-directory>
+   arm-none-eabi-gdb nuttx
+   gdb> target remote localhost:3333
+   gdb> mon reset
+   gdb> mon halt
+   gdb> load nuttx
+
+3) Running NuttX
+
+   gdb> mon reset
+   gdb> c
+
+LEDs
+====
+
+The STM3210E-EVAL board has four LEDs labeled LD1, LD2, LD3 and LD4 on the
+board.. These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
+defined.  In that case, the usage by the board port is defined in
+include/board.h and src/up_leds.c. The LEDs are used to encode OS-related
+events as follows:
+
+    SYMBOL           Meaning                 LED1* LED2  LED3  LED4
+    ---------------- ----------------------- ----- ----- ----- -----
+    LED_STARTED      NuttX has been started  ON    OFF   OFF   OFF
+    LED_HEAPALLOCATE Heap has been allocated OFF   ON    OFF   OFF
+    LED_IRQSENABLED  Interrupts enabled      ON    ON    OFF   OFF
+    LED_STACKCREATED Idle stack created      OFF   OFF   ON    OFF
+    LED_INIRQ        In an interrupt**       ON    N/C   N/C   OFF
+    LED_SIGNAL       In a signal handler***  N/C   ON    N/C   OFF
+    LED_ASSERTION    An assertion failed     ON    ON    N/C   OFF
+    LED_PANIC        The system has crashed  N/C   N/C   N/C   ON
+    LED_IDLE         STM32 is is sleep mode  (Optional, not used)
+
+  * If LED1, LED2, LED3 are statically on, then NuttX probably failed to boot
+    and these LEDs will give you some indication of where the failure was
+ ** The normal state is LED3 ON and LED1 faintly glowing.  This faint glow
+    is because of timer interupts that result in the LED being illuminated
+    on a small proportion of the time.
+*** LED2 may also flicker normally if signals are processed.
+
+Temperature Sensor
+==================
+
+Support for the on-board LM-75 temperature sensor is available.  This supported
+has been verified, but has not been included in any of the available the
+configurations.  To set up the temperature sensor, add the following to the
+NuttX configuration file
+
+  CONFIG_I2C=y
+  CONFIG_I2C_LM75=y
+
+Then you can implement logic like the following to use the temperature sensor:
+
+  #include <nuttx/sensors/lm75.h>
+  #include <arch/board/board.h>
+
+  ret =  stm32_lm75initialize("/dev/temp");       /* Register the temperature sensor */
+  fd = open("/dev/temp", O_RDONLY);               /* Open the temperature sensor device */
+  ret = ioctl(fd, SNIOC_FAHRENHEIT, 0);           /* Select Fahrenheit */
+  bytesread = read(fd, buffer, 8*sizeof(b16_t));  /* Read temperature samples */
+
+More complex temperature sensor operations are also available.  See the IOCTAL
+commands enumerated in include/nuttx/sensors/lm75.h.  Also read the descriptions
+of the stm32_lm75initialize() and stm32_lm75attach() interfaces in the
+arch/board/board.h file (sames as configs/stm3210e-eval/include/board.h).
+
+RTC
+===
+
+  The STM32 RTC may configured using the following settings.
+
+    CONFIG_RTC - Enables general support for a hardware RTC. Specific
+      architectures may require other specific settings.
+    CONFIG_RTC_HIRES - The typical RTC keeps time to resolution of 1
+      second, usually supporting a 32-bit time_t value.  In this case,
+      the RTC is used to &quot;seed&quot; the normal NuttX timer and the
+      NuttX timer provides for higher resoution time. If CONFIG_RTC_HIRES
+      is enabled in the NuttX configuration, then the RTC provides higher
+      resolution time and completely replaces the system timer for purpose of
+      date and time.
+      CONFIG_RTC_FREQUENCY - If CONFIG_RTC_HIRES is defined, then the
+      frequency of the high resolution RTC must be provided.  If CONFIG_RTC_HIRES
+      is not defined, CONFIG_RTC_FREQUENCY is assumed to be one.
+    CONFIG_RTC_ALARM - Enable if the RTC hardware supports setting of an alarm. 
+      A callback function will be executed when the alarm goes off
+
+  In hi-res mode, the STM32 RTC operates only at 16384Hz.  Overflow interrupts
+  are handled when the 32-bit RTC counter overflows every 3 days and 43 minutes.
+  A BKP register is incremented on each overflow interrupt creating, effectively,
+  a 48-bit RTC counter.
+
+  In the lo-res mode, the RTC operates at 1Hz.  Overflow interrupts are not handled
+  (because the next overflow is not expected until the year 2106.
+
+   WARNING:  Overflow interrupts are lost whenever the STM32 is powered down.  The
+   overflow interrupt may be lost even if the STM32 is powered down only momentarily.
+   Therefore hi-res solution is only useful in systems where the power is always on.
+
+FSMC SRAM
+=========
+
+The 8-Mbit SRAM is connected to the STM32 at PG10 which will be FSMC_NE3, Bank1
+SRAM3.  This memory will appear at address 0x68000000.
+
+The on-board SRAM can be configured by setting
+
+  CONFIG_STM32_FSMC=y                         : Enables the FSMC
+  CONFIG_STM32_FSMC_SRAM=y                    : Enable external SRAM support
+  CONFIG_HEAP2_BASE=0x68000000                : SRAM will be located at 0x680000000
+  CONFIG_HEAP2_SIZE=1048576                   : The size of the SRAM is 1Mbyte
+  CONFIG_MM_REGIONS=2                         : There will be two memory regions
+                                              : in the heap
+
+STM3210E-EVAL-specific Configuration Options
+============================================
+
+    CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+       be set to:
+
+       CONFIG_ARCH=arm
+
+    CONFIG_ARCH_family - For use in C code:
+
+       CONFIG_ARCH_ARM=y
+
+    CONFIG_ARCH_architecture - For use in C code:
+
+       CONFIG_ARCH_CORTEXM3=y
+
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+       CONFIG_ARCH_CHIP=stm32
+
+    CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+       chip:
+
+       CONFIG_ARCH_CHIP_STM32F103ZET6
+
+    CONFIG_ARCH_BOARD_STM32_CUSTOM_CLOCKCONFIG - Enables special STM32 clock
+       configuration features.
+
+       CONFIG_ARCH_BOARD_STM32_CUSTOM_CLOCKCONFIG=n
+ 
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+
+       CONFIG_ARCH_BOARD=stm3210e_eval (for the STM3210E-EVAL development board)
+
+    CONFIG_ARCH_BOARD_name - For use in C code
+
+       CONFIG_ARCH_BOARD_STM3210E_EVAL=y
+
+    CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+       of delay loops
+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_DRAM_SIZE - Describes the installed DRAM (SRAM in this case):
+
+       CONFIG_DRAM_SIZE=0x00010000 (64Kb)
+
+    CONFIG_DRAM_START - The start address of installed DRAM
+
+       CONFIG_DRAM_START=0x20000000
+
+    CONFIG_ARCH_IRQPRIO - The STM32F103Z supports interrupt prioritization
+
+       CONFIG_ARCH_IRQPRIO=y
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+       stack. If defined, this symbol is the size of the interrupt
+        stack in bytes.  If not defined, the user task stacks will be
+      used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.

+  Timer and I2C devices may need to the following to force power to be applied
+  unconditionally at power up.  (Otherwise, the device is powered when it is
+  initialized).
+
+    CONFIG_STM32_FORCEPOWER
+
+  Timer devices may be used for different purposes.  One special purpose is
+  to generate modulated outputs for such things as motor control.  If CONFIG_STM32_TIMn
+  is defined (as above) then the following may also be defined to indicate that
+  the timer is intended to be used for pulsed output modulation, ADC conversion,
+  or DAC conversion.  Note that ADC/DAC require two definition:  Not only do you have
+  to assign the timer (n) for used by the ADC or DAC, but then you also have to
+  configure which ADC or DAC (m) it is assigned to.
+
+    CONFIG_STM32_TIMn_PWM   Reserve timer n for use by PWM, n=1,..,8
+    CONFIG_STM32_TIMn_ADC   Reserve timer n for use by ADC, n=1,..,8

+    CONFIG_STM32_TIMn_DACm  Reserve timer n to trigger DACm, n=1,..,8, m=1,..,2
+
+  For each timer that is enabled for PWM usage, we need the following additional
+  configuration settings:
+
+    CONFIG_STM32_TIMx_CHANNEL - Specifies the timer output channel {1,..,4}
+ 
+  NOTE: The STM32 timers are each capable of generating different signals on
+  each of the four channels with different duty cycles.  That capability is
+  not supported by this driver:  Only one output channel per timer.
+
+  Alternate pin mappings.  The STM3210E-EVAL board requires only CAN1 remapping
+  On the STM3210E-EVAL board pin PB9 is wired as TX and pin PB8 is wired as RX.
+  Which then makes the proper connection through the CAN transiver SN65HVD230 
+  out to the CAN D-type 9-pn male connector where pin 2 is CANL and pin 7 is CANH.

+
+  STM3210E-EVAL LCD Hardware Configuration
+
+    CONFIG_LCD_LANDSCAPE - Define for 320x240 display "landscape"
+      support. Default is this 320x240 "landscape" orientation
+      (this setting is informative only... not used).
+    CONFIG_LCD_PORTRAIT - Define for 240x320 display "portrait"

+      320x240 "landscape" orientation.
+    CONFIG_LCD_RPORTRAIT - Define for 240x320 display "reverse
+      portrait" orientation support.  In this orientation, the
+      STM3210E-EVAL's LCD ribbon cable is at the top of the display.
+      Default is 320x240 "landscape" orientation.
+    CONFIG_LCD_BACKLIGHT - Define to support a backlight.
+    CONFIG_LCD_PWM - If CONFIG_STM32_TIM1 is also defined, then an

+    individual LCDs using:
+
+    CONFIG_STM32_AM240320_DISABLE
+    CONFIG_STM32_SPFD5408B_DISABLE
+    CONFIG_STM32_R61580_DISABLE

+    =========== ======================= ================================
+
+    (1) You will probably need to modify nsh/setenv.sh or nsh2/setenv.sh
+        to set up the correct PATH variable for whichever toolchain you
+        may use.
+    (2) Since DfuSe is assumed, this configuration may only work under
+        Cygwin without modification.
+    (3) When any other device other than /dev/console is used for a user
+        interface, (1) linefeeds (\n) will not be expanded to carriage return
+        / linefeeds \r\n). You will need to configure your terminal program
+        to account for this. And (2) input is not automatically echoed so
+        you will have to turn local echo on.
+    (4) Microsoft holds several patents related to the design of
+        long file names in the FAT file system.  Please refer to the
+        details in the top-level COPYING file.  Please do not use FAT
+        long file name unless you are familiar with these patent issues.
+    (5) When built as an NSH add-on command (CONFIG_EXAMPLES_USBMSC_BUILTIN=y),
+        Caution should be used to assure that the SD drive is not in use when
+        the USB storage device is configured.  Specifically, the SD driver
+        should be unmounted like:
+
+        nsh> mount -t vfat /dev/mmcsd0 /mnt/sdcard # Card is mounted in NSH
+        ...
+        nsh> umount /mnd/sdcard                    # Unmount before connecting USB!!!
+        nsh> msconn                                # Connect the USB storage device
+        ...
+        nsh> msdis                                 # Disconnect USB storate device
+        nsh> mount -t vfat /dev/mmcsd0 /mnt/sdcard # Restore the mount
+
+        Failure to do this could result in corruption of the SD card format.
+
+    The nsh2 contains support for some built-in applications that can be
+    enabled by make some additional minor changes:
+
+    (1) examples/can.  The CAN test example can be enabled by changing the
+        following settings in nsh2/defconfig:
+
+        CONFIG_CAN=y             # Enable CAN "upper-half" driver support
+        CONFIG_STM32_CAN1=y      # Enable STM32 CAN1 "lower-half" driver support
+
+        The default CAN settings may need to change in your board board
+        configuration:
+
+        CONFIG_CAN_EXTID=y       # Support extended IDs
+        CONFIG_CAN1_BAUD=250000  # Bit rate: 250 KHz
+        CONFIG_CAN_TSEG1=12      # 80% sample point
+        CONFIG_CAN_TSEG2=3
+  nx:
+  ---
+    An example using the NuttX graphics system (NX).  This example
+    focuses on general window controls, movement, mouse and keyboard
+    input.
+
+      CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+      CONFIG_LCD_RPORTRAIT=y        : 240x320 reverse portrait
+
+  nxconsole:
+  ----------
+    This is yet another NSH configuration.  This NSH configuration differs
+    from the other, however, in that it uses the NxConsole driver to host
+    the NSH shell.
+
+    Some of the differences in this configuration include these settings
+    in the defconfig file:
+
+    These select NX Multi-User mode:
+
+      CONFG_NX_MULTIUSER=y
+      CONFIG_DISABLE_MQUEUE=n
+ 
+    The following definition in the defconfig file to enables the NxConsole
+    driver:
+
+      CONFIG_NXCONSOLE=y
+
+    The appconfig file selects examples/nxconsole instead of examples/nsh:
+
+      CONFIGURED_APPS += examples/nxconsole
+
+    Other configuration settings:
+
+      CONFIG_STM32_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin
+      CONFIG_LCD_LANDSCAPE=y        : 320x240 landscape
+
+  nxlines:
+  ------
+    Another example using the NuttX graphics system (NX).   This
+    example focuses on placing lines on the background in various
+    orientations.
+
+      CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+      CONFIG_LCD_RPORTRAIT=y        : 240x320 reverse portrait
+
+  nxtext:
+  ------
+    Another example using the NuttX graphics system (NX).   This
+    example focuses on placing text on the background while pop-up
+    windows occur.  Text should continue to update normally with
+    or without the popup windows present.
+
+      CONFIG_STM32_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin
+      CONFIG_LCD_RPORTRAIT=y        : 240x320 reverse portrait
+
+    NOTE:  When I tried building this example with the CodeSourcery
+    tools, I got a hardfault inside of its libgcc.  I haven't
+    retested since then, but beware if you choose to change the
+    toolchain.
+
+  ostest:
+  ------
+    This configuration directory, performs a simple OS test using
+    examples/ostest.  By default, this project assumes that you are
+    using the DFU bootloader.
+
+      CONFIG_STM32_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin
+
+  pm:
+  --
+    This is a configuration that is used to test STM32 power management, i.e.,
+    to test that the board can go into lower and lower states of power usage
+    as a result of inactivity.  This configuration is based on the nsh2
+    configuration with modifications for testing power management.  This
+    configuration should provide some guideline for power management in your
+    STM32 application.
+
+      CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+
+    CONFIG_PM_CUSTOMINIT and CONFIG_IDLE_CUSTOM are necessary parts of the
+    PM configuration:
+
+      CONFIG_PM_CUSTOMINIT=y
+
+    CONFIG_PM_CUSTOMINIT moves the PM initialization from arch/arm/src/stm32/stm32_pminitialiaze.c
+    to configs/stm3210-eval/src/up_pm.c.  This allows us to support board-
+    specific PM initialization.
+    
+      CONFIG_IDLE_CUSTOM=y
+
+    The bulk of the PM activities occur in the IDLE loop.  The IDLE loop is
+    special because it is what runs when there is no other task running.  Therefore
+    when the IDLE executes, we can be assure that nothing else is going on; this
+    is the ideal condition for doing reduced power management.
+
+    The configuration CONFIG_IDLE_CUSTOM allows us to "steal" the normal STM32
+    IDLE loop (of arch/arm/src/stm32/stm32_idle.c) and replace this with our own
+    custom IDLE loop (at configs/stm3210-eval/src/up_idle.c).
+
+    Here are some additional things to note in the configuration:
+
+      CONFIG_PM_BUTTONS=y
+    
+    CONFIG_PM_BUTTONS enables button support for PM testing.  Buttons can drive
+    EXTI interrupts and EXTI interrrupts can be used to wakeup for certain reduced
+    power modes (STOP mode).  The use of the buttons here is for PM testing purposes
+    only; buttons would normally be part the application code and CONFIG_PM_BUTTONS
+    would not be defined.
+
+      CONFIG_RTC_ALARM=y
+
+    The RTC alarm is used to wake up from STOP mode and to transition to
+    STANDBY mode.  This used of the RTC alarm could conflict with other uses of
+    the RTC alarm in your application.
+
+  RIDE
+  ----
+    This configuration builds a trivial bring-up binary.  It is
+    useful only because it words with the RIDE7 IDE and R-Link debugger.
+
+      CONFIG_STM32_RAISONANCE=y     : Raisonance RIDE7 under Windows
+
+  usbserial:
+  ---------
+    This configuration directory exercises the USB serial class
+    driver at examples/usbserial.  See examples/README.txt for
+    more information.
+
+      CONFIG_STM32_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin
+
+    USB debug output can be enabled as by changing the following
+    settings in the configuration file:
+
+      -CONFIG_DEBUG=n
+      -CONFIG_DEBUG_VERBOSE=n
+      -CONFIG_DEBUG_USB=n
+      +CONFIG_DEBUG=y
+      +CONFIG_DEBUG_VERBOSE=y
+      +CONFIG_DEBUG_USB=y
+
+      -CONFIG_EXAMPLES_USBSERIAL_TRACEINIT=n
+      -CONFIG_EXAMPLES_USBSERIAL_TRACECLASS=n
+      -CONFIG_EXAMPLES_USBSERIAL_TRACETRANSFERS=n
+      -CONFIG_EXAMPLES_USBSERIAL_TRACECONTROLLER=n
+      -CONFIG_EXAMPLES_USBSERIAL_TRACEINTERRUPTS=n
+      +CONFIG_EXAMPLES_USBSERIAL_TRACEINIT=y
+      +CONFIG_EXAMPLES_USBSERIAL_TRACECLASS=y
+      +CONFIG_EXAMPLES_USBSERIAL_TRACETRANSFERS=y
+      +CONFIG_EXAMPLES_USBSERIAL_TRACECONTROLLER=y
+      +CONFIG_EXAMPLES_USBSERIAL_TRACEINTERRUPTS=y
+
+    By default, the usbserial example uses the Prolific PL2303
+    serial/USB converter emulation.  The example can be modified
+    to use the CDC/ACM serial class by making the following changes
+    to the configuration file:
+
+      -CONFIG_PL2303=y
+      +CONFIG_PL2303=n
+
+      -CONFIG_CDCACM=n
+      +CONFIG_CDCACM=y
+
+    The example can also be converted to use the alternative
+    USB serial example at apps/examples/usbterm by changing the 
+    following:
+
+      -CONFIGURED_APPS += examples/usbserial
+      +CONFIGURED_APPS += examples/usbterm
+
+    In either the original appconfig file (before configuring)
+    or in the final apps/.config file (after configuring).
+
+  usbstorage:
+  ----------
+    This configuration directory exercises the USB mass storage
+    class driver at examples/usbstorage.  See examples/README.txt for
+    more information.
+
+      CONFIG_STM32_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin

+README

+------

+

+This directory contains a simple RIDE7 project used to bring up the

+STM3210E-EVAL board.  This project includes only the STM32 boot-up

+code under arch/arm/src and configs/stm3210e-eval/src plus as little

+additional environmental support as necessary.

+

+bigfatstub.c

+

+  The NuttX OS is not included in this project.  This file contains

+  stubs for all of the NuttX entry points and this replaces NuttX

+

+Make.defs, defconfig, setenv.h

+

+  The first step to using this RIDE project is to build a compatible

+  cygwin project.  This will set up of the directories and produce

+  all of the necessary autogenerated files.

+

+    cd tools

+    ./configure.sh stm3210e-eva/RIDE

+    cd ..

+    . ./setenv.sh

+    make

+

+nuttx.*

+

+  RIDE7 project files

+  

+stm32-nuttx.ld

+

+  This is the linker script that replaces the RIDE7 linker script.

+

+stm32-ld.sh

+

+  This is a shell script that will use the RIDE7 tools to relink the

+  NuttX binaries.  Useful because RIDE7 does not provide much linker

+  output to see what is going on.

+Repair procedure for ARM-USB-OCD drivers
+
+1.   Uninstalling ARM-USB-OCD drivers
+-------------------------------------
+1.1. Connect your programmer/debugger to your computer, open Device Manager
+     and uninstall the drivers for ARM-USB-OCD.
+1.2. After you have uninstalled ARM-USB-TINY driver from Device Manager,
+     disconnect the programmer from your computer.
+1.3. Now you should download FTClean.exe from here:
+     http://www.ftdichip.com/Support/Utilities/FTClean.zip.
+1.4. After download is complete extract the "*.zip" file, open folder FTClean,
+     and run FTClean.exe
+1.5. Ror VID (Hex) select "Other". And after that fill the first box with 15ba
+     and "PID (Hex)" with 0004.
+1.6. Press "Clean System" button.  Make sure that all FTDI devices are
+     disconnected. (My require administrator privileges).
+
+2. Re-installing the ARM-USB-OCD driver
+---------------------------------------
+2.1 Connect the programmer/debugger to the computer.
+2.2 When prompted, browse to the C:\gccfd\DRIVERS\ARM-USB-OCD-DRIVER
+    directory and install. (A different driver is required for OpenOCD
+    0.4.0.  That driver is available from the olimex.com web site).

+Development Environment
+=======================
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment because the Raisonance R-Link emulatator and some RIDE7 development tools
+  were used and those tools works only under Windows.
+
+GNU Toolchain Options
+=====================
+
+  Toolchain Configurations
+  ------------------------
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The Atollic Toolchain,
+  3. The devkitARM GNU toolchain,
+  4. Raisonance GNU toolchain, or
+  5. The NuttX buildroot Toolchain (see below).
+
+  Most testing has been conducted using the CodeSourcery toolchain for Windows and
+  that is the default toolchain in most configurations.  To use the Atollic
+  devkitARM, Raisonance GNU, or NuttX buildroot toolchain, you simply need to
+  add one of the following configuration options to your .config (or defconfig)
+  file:
+
+    CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_STM32_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_STM32_ATOLLIC_LITE=y   : The free, "Lite" version of Atollic toolchain under Windows
+    CONFIG_STM32_ATOLLIC_PRO=y    : The paid, "Pro" version of Atollic toolchain under Windows
+    CONFIG_STM32_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_STM32_RAISONANCE=y     : Raisonance RIDE7 under Windows
+    CONFIG_STM32_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin (default)
+
+  If you change the default toolchain, then you may also have to modify the PATH in
+  the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows), Atollic, devkitARM, and Raisonance toolchains are
+  Windows native toolchains.  The CodeSourcey (for Linux) and NuttX buildroot
+  toolchains are Cygwin and/or Linux native toolchains. There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  The CodeSourcery Toolchain (2009q1)
+  -----------------------------------
+  The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  The Atollic "Pro" and "Lite" Toolchain
+  --------------------------------------
+  One problem that I had with the Atollic toolchains is that the provide a gcc.exe
+  and g++.exe in the same bin/ file as their ARM binaries.  If the Atollic bin/ path
+  appears in your PATH variable before /usr/bin, then you will get the wrong gcc
+  when you try to build host executables.  This will cause to strange, uninterpretable
+  errors build some host binaries in tools/ when you first make.
+
+  The Atollic "Lite" Toolchain
+  ----------------------------
+  The free, "Lite" version of the Atollic toolchain does not support C++ nor
+  does it support ar, nm, objdump, or objdcopy. If you use the Atollic "Lite"
+  toolchain, you will have to set:
+
+    CONFIG_HAVE_CXX=n
+
+  In order to compile successfully.  Otherwise, you will get errors like:
+
+    "C++ Compiler only available in TrueSTUDIO Professional"
+
+  The make may then fail in some of the post link processing because of some of
+  the other missing tools.  The Make.defs file replaces the ar and nm with
+  the default system x86 tool versions and these seem to work okay.  Disable all
+  of the following to avoid using objcopy:
+
+    CONFIG_RRLOAD_BINARY=n
+    CONFIG_INTELHEX_BINARY=n
+    CONFIG_MOTOROLA_SREC=n
+    CONFIG_RAW_BINARY=n
+
+  devkitARM
+  ---------
+  The devkitARM toolchain includes a version of MSYS make.  Make sure that the
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+====
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project.
+
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/stm32,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/stm32/stm32_vectors.S.  With RIDE, I have to build NuttX
+  one time from the Cygwin command line in order to obtain the pre-built
+  startup object needed by RIDE.
+
+NuttX buildroot Toolchain
+=========================
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh stm3220g-eval/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you are
+  building a Cortex-M3 toolchain for Cygwin under Windows.
+
+Ethernet
+========
+
+The Ethernet driver is configured to use the MII interface:
+
+  Board Jumper Settings:
+
+    Jumper  Description
+    JP8     To enable MII, JP8 should not be fitted.
+    JP6     2-3: Enable MII interface mode
+    JP5     2-3: Provide 25 MHz clock for MII or 50 MHz clock for RMII by MCO at PA8
+    SB1     Not used with MII
+
+LEDs
+====
+
+The STM3220G-EVAL board has four LEDs labeled LD1, LD2, LD3 and LD4 on the
+board.. These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
+defined.  In that case, the usage by the board port is defined in
+include/board.h and src/up_leds.c. The LEDs are used to encode OS-related\

+
+PWM
+===
+
+The STM3220G-Eval has no real on-board PWM devices, but the board can be
+configured to output a pulse train using timer output pins.  The following
+pins have been use to generate PWM output (see board.h for some other
+candidates):
+
+TIM4 CH2.  Pin PD13 is used by the FSMC (FSMC_A18) and is also connected
+to the Motor Control Connector (CN5) just for this purpose.  If FSMC is
+not enabled, then FSMC_A18 will not be used (and will be tri-stated from
+the LCD).
+
+  CONFIGURATION:
+
+    CONFIG_STM32_TIM4=y
+    CONFIG_PWM=n
+    CONFIG_PWM_PULSECOUNT=n
+    CONFIG_STM32_TIM4_PWM=y
+    CONFIG_STM32_TIM4_CHANNEL=2
+
+  ACCESS:
+
+    Daughterboard Extension Connector, CN3, pin 32
+    Ground is available on CN3, pin1
+
+  NOTE: TIM4 hardware will not support pulse counting.
+
+TIM8 CH4:  Pin PC9 is used by the microSD card (MicroSDCard_D1) and I2S
+(I2S_CKIN) but can be completely disconnected from both by opening JP16.
+
+  CONFIGURATION:
+
+    CONFIG_STM32_TIM8=y
+    CONFIG_PWM=n
+    CONFIG_PWM_PULSECOUNT=y

+
+  ACCESS:
+
+    Daughterboard Extension Connector, CN3, pin 17
+    Ground is available on CN3, pin1
+
+CAN
+===
+
+Connector 10 (CN10) is DB-9 male connector that can be used with CAN1 or CAN2.
+
+  JP10 connects CAN1_RX or CAN2_RX to the CAN transceiver
+  JP3 connects CAN1_TX or CAN2_TX to the CAN transceiver
+
+CAN signals are then available on CN10 pins:
+
+  CN10 Pin 7 = CANH
+  CN10 Pin 2 = CANL
+
+Mapping to STM32 GPIO pins:
+
+  PD0   = FSMC_D2 & CAN1_RX
+  PD1   = FSMC_D3 & CAN1_TX
+  PB13  = ULPI_D6 & CAN2_TX
+  PB5   = ULPI_D7 & CAN2_RX
+

+FSMC SRAM
+=========
+
+On-board SRAM
+-------------
+
+A 16 Mbit SRAM is connected to the STM32F407IGH6 FSMC bus which shares the same
+I/Os with the CAN1 bus. Jumper settings:
+
+  JP1: Connect PE4 to SRAM as A20
+  JP2: onnect PE3 to SRAM as A19
+
+JP3 and JP10 must not be fitted for SRAM and LCD application.  JP3 and JP10
+select CAN1 or CAN2 if fitted; neither if not fitted.
+
+The on-board SRAM can be configured by setting
+
+  CONFIG_STM32_FSMC=y
+  CONFIG_STM32_FSMC_SRAM=y
+  CONFIG_HEAP2_BASE=0x64000000
+  CONFIG_HEAP2_SIZE=2097152
+  CONFIG_MM_REGIONS=2
+
+Configuration Options
+---------------------
+
+Internal SRAM is available in all members of the STM32 family. In addition
+to internal SRAM, SRAM may also be available through the FSMC.  In order to
+use FSMC SRAM, the following additional things need to be present in the
+NuttX configuration file:
+
+  CONFIG_STM32_FSMC=y        : Enables the FSMC
+  CONFIG_STM32_FSMC_SRAM=y   : Indicates that SRAM is available via the
+                               FSMC (as opposed to an LCD or FLASH).
+  CONFIG_HEAP2_BASE          : The base address of the SRAM in the FSMC
+                               address space
+  CONFIG_HEAP2_SIZE          : The size of the SRAM in the FSMC
+                               address space
+  CONFIG_MM_REGIONS          : Must be set to a large enough value to
+                               include the FSMC SRAM
+
+SRAM Configurations
+-------------------
+There are 2 possible SRAM configurations:
+
+  Configuration 1. System SRAM (only)
+                   CONFIG_MM_REGIONS == 1
+  Configuration 2. System SRAM and FSMC SRAM
+                   CONFIG_MM_REGIONS == 2
+                   CONFIG_STM32_FSMC_SRAM defined

+
+       CONFIG_DRAM_START=0x20000000
+
+    In addition to internal SRAM, SRAM may also be available through the FSMC.
+    In order to use FSMC SRAM, the following additional things need to be
+    present in the NuttX configuration file:
+
+    CONFIG_STM32_FSMC_SRAM - Indicates that SRAM is available via the
+      FSMC (as opposed to an LCD or FLASH).

+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that

+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.

+  is defined (as above) then the following may also be defined to indicate that
+  the timer is intended to be used for pulsed output modulation, ADC conversion,

+    CONFIG_STM32_CODESOURCERYW=y                  : CodeSourcery under Windows
+    CONFIG_NSH_DHCPC=n                            : DHCP is disabled

+
+    NOTES:
+    1. This example assumes that a network is connected.  During its
+       initialization, it will try to negotiate the link speed.  If you have
+       no network connected when you reset the board, there will be a long
+       delay (maybe 30 seconds?) before anything happens.  That is the timeout
+       before the networking finally gives up and decides that no network is
+       available.
+
+    2. This example supports the ADC test (apps/examples/adc) but this must
+       be manually enabled by selecting:
+
+       CONFIG_ADC=y             : Enable the generic ADC infrastructure
+       CONFIG_STM32_ADC3=y      : Enable ADC3
+       CONFIG_STM32_TIM1=y      : Enable Timer 1
+       CONFIG_STM32_TIM1_ADC=y  : Indicate that timer 1 will be used to trigger an ADC
+       CONFIG_STM32_TIM1_ADC3=y : Assign timer 1 to drive ADC3 sampling
+       CONFIG_STM32_ADC3_SAMPLE_FREQUENCY=100 : Select a sampling frequency
+
+       See also apps/examples/README.txt
+
+       General debug for analog devices (ADC/DAC):
+
+       CONFIG_DEBUG_ANALOG
+
+    3. This example supports the PWM test (apps/examples/pwm) but this must
+       be manually enabled by selecting eeither
+
+       CONFIG_PWM=y                : Enable the generic PWM infrastructure
+       CONFIG_PWM_PULSECOUNT=n     : Disable to support for TIM1/8 pulse counts
+       CONFIG_STM32_TIM4=y         : Enable TIM4
+       CONFIG_STM32_TIM4_PWM=y     : Use TIM4 to generate PWM output
+       CONFIG_STM32_TIM4_CHANNEL=2 : Select output on TIM4, channel 2
+
+       If CONFIG_STM32_FSMC is disabled, output will appear on CN3, pin 32.
+       Ground is available on CN3, pin1.
+
+       Or..
+
+       CONFIG_PWM=y                : Enable the generic PWM infrastructure
+       CONFIG_PWM_PULSECOUNT=y     : Enable to support for TIM1/8 pulse counts
+       CONFIG_STM32_TIM8=y         : Enable TIM8
+       CONFIG_STM32_TIM8_PWM=y     : Use TIM8 to generate PWM output
+       CONFIG_STM32_TIM8_CHANNEL=4 : Select output on TIM8, channel 4
+
+       If CONFIG_STM32_FSMC is disabled, output will appear on CN3, pin 17
+       Ground is available on CN23 pin1.
+
+       See also include/board.h and apps/examples/README.txt
+
+       Special PWM-only debug options:
+
+       CONFIG_DEBUG_PWM
+
+    4. This example supports the CAN loopback test (apps/examples/can) but this
+       must be manually enabled by selecting:
+
+       CONFIG_CAN=y             : Enable the generic CAN infrastructure
+       CONFIG_CAN_EXID=y or n   : Enable to support extended ID frames
+       CONFIG_STM32_CAN1=y      : Enable CAN1
+       CONFIG_CAN_LOOPBACK=y    : Enable CAN loopback mode
+
+       See also apps/examples/README.txt
+
+       Special CAN-only debug options:
+
+       CONFIG_DEBUG_CAN
+       CONFIG_CAN_REGDEBUG
+
+    5. This example can support an FTP client.  In order to build in FTP client
+       support simply uncomment the following lines in the appconfig file (before
+       configuring) or in the apps/.config file (after configuring):
+
+       #CONFIGURED_APPS += netutils/ftpc
+       #CONFIGURED_APPS += examples/ftpc
+
+    6. This example can support an FTP server.  In order to build in FTP server
+       support simply uncomment the following lines in the appconfig file (before
+       configuring) or in the apps/.config file (after configuring):
+
+       #CONFIGURED_APPS += netutils/ftpd
+       #CONFIGURED_APPS += examples/ftpd
+
+       And enable poll() support in the NuttX configuration file:
+
+       CONFIG_DISABLE_POLL=n
+
+    7. This example supports the watchdog timer test (apps/examples/watchdog)
+       but this must be manually enabled by selecting:
+
+       CONFIG_WATCHDOG=y         : Enables watchdog timer driver support
+       CONFIG_STM32_WWDG=y       : Enables the WWDG timer facility, OR
+       CONFIG_STM32_IWDG=y       : Enables the IWDG timer facility (but not both)
+
+       The WWDG watchdog is driven off the (fast) 42MHz PCLK1 and, as result,
+       has a maximum timeout value of 49 milliseconds.  For WWDG watchdog, you
+       should also add the fillowing to the configuration file:
+
+       CONFIG_EXAMPLES_WATCHDOG_PINGDELAY=20
+       CONFIG_EXAMPLES_WATCHDOG_TIMEOUT=49
+
+       The IWDG timer has a range of about 35 seconds and should not be an issue.
+
+    7. Adding LCD and graphics support:
+
+       appconfig (apps/.config):  Enable the application configurations that you
+       want to use.  Asexamples:
+
+       CONFIGURED_APPS += examples/nx       : Pick one or more
+       CONFIGURED_APPS += examples/nxhello  :
+       CONFIGURED_APPS += examples/nximage  :
+       CONFIGURED_APPS += examples/nxlines  :
+
+       defconfig (nuttx/.config):
+
+       CONFIG_STM32_FSMC=y                  : FSMC support is required for the LCD
+       CONFIG_NX=y                          : Enable graphics suppport
+       CONFIG_MM_REGIONS=2                  : When FSMC is enabled, so is the on-board SRAM memory region
+
+    8. USB OTG FS Device or Host Support
+ 
+       CONFIG_USBDEV          - Enable USB device support, OR
+       CONFIG_USBHOST         - Enable USB host support (but not both)
+
+       CONFIG_STM32_OTGFS     - Enable the STM32 USB OTG FS block
+       CONFIG_STM32_SYSCFG    - Needed for all USB OTF FS support
+
+       CONFIG_SCHED_WORKQUEUE - Worker thread support is required for the mass
+                                storage class (both host and device).
+       CONFIG_NSH_ARCHINIT    - Architecture specific USB initialization
+                                is needed
+
+    9. This configuration requires that jumper JP22 be set to enable RS-232 operation.
+
+  nsh2:
+  -----
+
+    This is an alternaitve NSH configuration.  One limitation of the STM3220G-EVAL
+    board is that you cannot have both a UART-based NSH console and SDIO support.
+    The nsh2 differs from the nsh configuration in the following ways:
+
+    -CONFIG_STM32_USART3=y      : USART3 is disabled
+    + CONFIG_STM32_USART3=n
+
+    -CONFIG_STM32_SDIO=n        : SDIO is enabled
+    +CONFIG_STM32_SDIO=y
+
+    Logically, these are the only differences:  This configuration has SDIO (and
+    the SD card) enabled and the serial console disabled. There is ONLY a
+    Telnet console!.
+
+    There are some special settings to make life with only a Telnet
+
+    CONFIG_SYSLOG=y - Enables the System Logging feature.
+    CONFIG_RAMLOG=y - Enable the RAM-based logging feature.
+    CONFIG_RAMLOG_CONSOLE=y - Use the RAM logger as the default console.
+      This means that any console output from non-Telnet threads will
+      go into the circular buffer in RAM.
+    CONFIG_RAMLOG_SYSLOG - This enables the RAM-based logger as the
+      system logger.  This means that (1) in addition to the console
+      output from other tasks, ALL of the debug output will also to
+      to the circular buffer in RAM, and (2) NSH will now support a
+      command called 'dmesg' that can be used to dump the RAM log.
+
+    There are a few other configuration differences as necessary to support
+    this different device configuration. Just the do the 'diff' if you are
+    curious.
+
+    NOTES:
+    1. See the notes for the nsh configuration.  Most also apply to the nsh2
+       configuration.
+
+    2. RS-232 is disabled, but Telnet is still available for use as a console.
+       Since RS-232 and SDIO use the same pins (one controlled by JP22), RS232
+       and SDIO cannot be used concurrently.
+
+    3. This configuration requires that jumper JP22 be set to enable SDIO
+       operation.  To enable MicroSD Card, which shares same I/Os with RS-232,
+       JP22 is not fitted.
+
+    4. In order to use SDIO without overruns, DMA must be used.
+
+    5. Another SDIO/DMA issue.  This one is probably a software bug.  This is
+       the bug as stated in the TODO list:
+
+       "If you use a large I/O buffer to access the file system, then the
+        MMCSD driver will perform multiple block SD transfers.  With DMA
+        ON, this seems to result in CRC errors detected by the hardware
+        during the transfer.  Workaround:  CONFIG_MMCSD_MULTIBLOCK_DISABLE=y"
+
+       For this reason, CONFIG_MMCSD_MULTIBLOCK_DISABLE=y appears in the defconfig
+       file.
+
+    6. Another DMA-related concern.  I see this statement in the reference
+       manual:  "The burst configuration has to be selected in order to respect
+       the AHB protocol, where bursts must not cross the 1 KB address boundary
+       because the minimum address space that can be allocated to a single slave
+       is 1 KB. This means that the 1 KB address boundary should not be crossed
+       by a burst block transfer, otherwise an AHB error would be generated,
+       that is not reported by the DMA registers."
+
+       There is nothing in the DMA driver to prevent this now.
+
+  nxwm
+  ----
+    This is a special configuration setup for the NxWM window manager
+    UnitTest.  The NxWM window manager can be found here:
+
+      trunk/NxWidgets/nxwm
+
+    The NxWM unit test can be found at:
+
+      trunk/NxWidgets/UnitTests/nxwm
+
+    Documentation for installing the NxWM unit test can be found here:
+
+      trunk/NxWidgets/UnitTests/README.txt
+
+    Here is the quick summary of the build steps:
+
+    1. Intall the nxwm configuration
+
+       $ cd ~/nuttx/trunk/nuttx/tools
+       $ ./configure.sh stm3220g-eval/nxwm
+
+    2. Make the build context (only)
+
+       $ cd ..
+       $ . ./setenv.sh
+       $ make context
+       ...
+
+    3. Install the nxwm unit test
+
+       $ cd ~/nuttx/trunk/NxWidgets
+       $ tools/install.sh ~/nuttx/trunk/apps nxwm
+       Creating symbolic link
+        - To ~/nuttx/trunk/NxWidgets/UnitTests/nxwm
+        - At ~/nuttx/trunk/apps/external
+
+    4. Build the NxWidgets library
+
+       $ cd ~/nuttx/trunk/NxWidgets/libnxwidgets
+       $ make TOPDIR=~/nuttx/trunk/nuttx
+       ...
+
+    5. Build the NxWM library
+
+       $ cd ~/nuttx/trunk/NxWidgets/nxwm
+       $ make TOPDIR=~//nuttx/trunk/nuttx
+       ...
+
+    6. Built NuttX with the installed unit test as the application
+
+       $ cd ~/nuttx/trunk/nuttx
+       $ make
+
+  ostest:
+  ------
+    This configuration directory, performs a simple OS test using
+    examples/ostest.  By default, this project assumes that you are
+    using the DFU bootloader.
+
+    CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+
+  telnetd:
+  --------
+
+    A simple test of the Telnet daemon(see apps/netutils/README.txt,
+    apps/examples/README.txt, and apps/examples/telnetd).  This is
+    the same daemon that is used in the nsh configuration so if you
+    use NSH, then you don't care about this.  This test is good for
+    testing the Telnet daemon only because it works in a simpler
+    environment than does the nsh configuration.

+ *   General transaction rules.  The requested AHB transaction data size can be 8-,

+ *   Case 2: AHB transaction size is greater than the memory size
+ *     In this case, the FSMC splits the AHB transaction into smaller consecutive
+ *     memory accesses in order to meet the external data width.
+ *   Case 3: AHB transaction size is smaller than the memory size.
+ *     SRAM supports the byte select feature.
+ *     a) FSMC allows write transactions accessing the right data through its
+ *        byte lanes (NBL[1:0])
+ *     b) Read transactions are allowed (the controller reads the entire memory
+ *        word and uses the needed byte only). The NBL[1:0] are always kept low
+ *        during read transactions.

+ *
+ *   General transaction rules.  The requested AHB transaction data size can be 8-,
+ *   16- or 32-bit wide whereas the SRAM has a fixed 16-bit data width. Some simple
+ *   transaction rules must be followed:
+ *
+ *   Case 1: AHB transaction width and SRAM data width are equal
+ *     There is no issue in this case.
+ *   Case 2: AHB transaction size is greater than the memory size
+ *     In this case, the FSMC splits the AHB transaction into smaller consecutive
+ *     memory accesses in order to meet the external data width.
+ *   Case 3: AHB transaction size is smaller than the memory size.
+ *     SRAM supports the byte select feature.
+ *     a) FSMC allows write transactions accessing the right data through its
+ *        byte lanes (NBL[1:0])
+ *     b) Read transactions are allowed (the controller reads the entire memory
+ *        word and uses the needed byte only). The NBL[1:0] are always kept low

+ *
+ *   1. Provide logic in stm32_boardinitialize() to configure SPI chip select
+ *      pins.
+ *   2. Provide stm32_spi1/2/3select() and stm32_spi1/2/3status() functions in your
+ *      board-specific logic.  These functions will perform chip selection and
+ *      status operations using GPIOs in the way your board is configured.
+ *   3. Add a calls to up_spiinitialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by up_spiinitialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling
+ *      mmcsd_spislotinitialize(), for example, will bind the SPI driver to
+ *      the SPI MMC/SD driver).

+Repair procedure for ARM-USB-OCD drivers
+
+1.   Uninstalling ARM-USB-OCD drivers
+-------------------------------------
+1.1. Connect your programmer/debugger to your computer, open Device Manager
+     and uninstall the drivers for ARM-USB-OCD.
+1.2. After you have uninstalled ARM-USB-TINY driver from Device Manager,
+     disconnect the programmer from your computer.
+1.3. Now you should download FTClean.exe from here:
+     http://www.ftdichip.com/Support/Utilities/FTClean.zip.
+1.4. After download is complete extract the "*.zip" file, open folder FTClean,
+     and run FTClean.exe
+1.5. Ror VID (Hex) select "Other". And after that fill the first box with 15ba
+     and "PID (Hex)" with 0004.
+1.6. Press "Clean System" button.  Make sure that all FTDI devices are
+     disconnected. (My require administrator privileges).
+
+2. Re-installing the ARM-USB-OCD driver
+---------------------------------------
+2.1 Connect the programmer/debugger to the computer.
+2.2 When prompted, browse to the C:\gccfd\DRIVERS\ARM-USB-OCD-DRIVER
+    directory and install. (A different driver is required for OpenOCD
+    0.4.0.  That driver is available from the olimex.com web site).

+Development Environment
+=======================
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment because the Raisonance R-Link emulatator and some RIDE7 development tools
+  were used and those tools works only under Windows.
+
+GNU Toolchain Options
+=====================
+
+  Toolchain Configurations
+  ------------------------
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The Atollic Toolchain,
+  3. The devkitARM GNU toolchain,
+  4. Raisonance GNU toolchain, or
+  5. The NuttX buildroot Toolchain (see below).
+
+  Most testing has been conducted using the CodeSourcery toolchain for Windows and
+  that is the default toolchain in most configurations (FPU-related testing has
+  been performed with the Atolloc toolchain for windows.  To use the Atollic,
+  devkitARM, Raisonance GNU, or NuttX buildroot toolchain, you simply need to
+  add one of the following configuration options to your .config (or defconfig)
+  file:
+
+    CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_STM32_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_STM32_ATOLLIC_LITE=y   : The free, "Lite" version of Atollic toolchain under Windows
+    CONFIG_STM32_ATOLLIC_PRO=y    : The paid, "Pro" version of Atollic toolchain under Windows
+    CONFIG_STM32_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_STM32_RAISONANCE=y     : Raisonance RIDE7 under Windows
+    CONFIG_STM32_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin (default)
+
+  If you change the default toolchain, then you may also have to modify the PATH in
+  the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows), Atollic, devkitARM, and Raisonance toolchains are
+  Windows native toolchains.  The CodeSourcery (for Linux) and NuttX buildroot
+  toolchains are Cygwin and/or Linux native toolchains. There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  The CodeSourcery Toolchain (2009q1)
+  -----------------------------------
+  The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  The Atollic "Pro" and "Lite" Toolchain
+  --------------------------------------
+  One problem that I had with the Atollic toolchains is that the provide a gcc.exe
+  and g++.exe in the same bin/ file as their ARM binaries.  If the Atollic bin/ path
+  appears in your PATH variable before /usr/bin, then you will get the wrong gcc
+  when you try to build host executables.  This will cause to strange, uninterpretable
+  errors build some host binaries in tools/ when you first make.
+
+  Also, the Atollic toolchains are the only toolchains that have built-in support for
+  the FPU in these configurations.  If you plan to use the Cortex-M4 FPU, you will
+  need to use the Atollic toolchain for now.  See the FPU section below for more
+  information.
+
+  The Atollic "Lite" Toolchain
+  ----------------------------
+  The free, "Lite" version of the Atollic toolchain does not support C++ nor
+  does it support ar, nm, objdump, or objdcopy. If you use the Atollic "Lite"
+  toolchain, you will have to set:
+
+    CONFIG_HAVE_CXX=n
+
+  In order to compile successfully.  Otherwise, you will get errors like:
+
+    "C++ Compiler only available in TrueSTUDIO Professional"
+
+  The make may then fail in some of the post link processing because of some of
+  the other missing tools.  The Make.defs file replaces the ar and nm with
+  the default system x86 tool versions and these seem to work okay.  Disable all
+  of the following to avoid using objcopy:
+
+    CONFIG_RRLOAD_BINARY=n
+    CONFIG_INTELHEX_BINARY=n
+    CONFIG_MOTOROLA_SREC=n
+    CONFIG_RAW_BINARY=n
+
+  devkitARM
+  ---------
+  The devkitARM toolchain includes a version of MSYS make.  Make sure that the
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+====
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project.
+
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/stm32,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/stm32/stm32_vectors.S.  With RIDE, I have to build NuttX
+  one time from the Cygwin command line in order to obtain the pre-built
+  startup object needed by RIDE.
+
+NuttX buildroot Toolchain
+=========================
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh stm3240g-eval/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you are
+  building a Cortex-M3 toolchain for Cygwin under Windows.
+
+Ethernet
+========
+
+The Ethernet driver is configured to use the MII interface:
+
+  Board Jumper Settings:
+
+    Jumper  Description
+    JP8     To enable MII, JP8 should not be fitted.
+    JP6     2-3: Enable MII interface mode
+    JP5     2-3: Provide 25 MHz clock for MII or 50 MHz clock for RMII by MCO at PA8
+    SB1     Not used with MII
+
+LEDs
+====
+
+The STM3240G-EVAL board has four LEDs labeled LD1, LD2, LD3 and LD4 on the
+board.. These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
+defined.  In that case, the usage by the board port is defined in
+include/board.h and src/up_leds.c. The LEDs are used to encode OS-related\
+events as follows:
+
+    SYMBOL               Meaning                 LED1*   LED2    LED3    LED4
+    -------------------  ----------------------- ------- ------- ------- ------
+    LED_STARTED          NuttX has been started  ON      OFF     OFF     OFF
+    LED_HEAPALLOCATE     Heap has been allocated OFF     ON      OFF     OFF
+    LED_IRQSENABLED      Interrupts enabled      ON      ON      OFF     OFF
+    LED_STACKCREATED     Idle stack created      OFF     OFF     ON      OFF
+    LED_INIRQ            In an interrupt**       ON      N/C     N/C     OFF
+    LED_SIGNAL           In a signal handler***  N/C     ON      N/C     OFF
+    LED_ASSERTION        An assertion failed     ON      ON      N/C     OFF
+    LED_PANIC            The system has crashed  N/C     N/C     N/C     ON
+    LED_IDLE             STM32 is is sleep mode  (Optional, not used)
+
+  * If LED1, LED2, LED3 are statically on, then NuttX probably failed to boot
+    and these LEDs will give you some indication of where the failure was
+ ** The normal state is LED3 ON and LED1 faintly glowing.  This faint glow
+    is because of timer interupts that result in the LED being illuminated
+    on a small proportion of the time.
+*** LED2 may also flicker normally if signals are processed.
+
+PWM
+===
+
+The STM3240G-Eval has no real on-board PWM devices, but the board can be
+configured to output a pulse train using timer output pins.  The following
+pins have been use to generate PWM output (see board.h for some other
+candidates):
+
+TIM4 CH2.  Pin PD13 is used by the FSMC (FSMC_A18) and is also connected
+to the Motor Control Connector (CN5) just for this purpose.  If FSMC is
+not enabled, then FSMC_A18 will not be used (and will be tri-stated from
+the LCD).
+
+  CONFIGURATION:
+
+    CONFIG_STM32_TIM4=y
+    CONFIG_PWM=n
+    CONFIG_PWM_PULSECOUNT=n
+    CONFIG_STM32_TIM4_PWM=y
+    CONFIG_STM32_TIM4_CHANNEL=2
+
+  ACCESS:
+
+    Daughterboard Extension Connector, CN3, pin 32
+    Ground is available on CN3, pin1
+
+  NOTE: TIM4 hardware will not support pulse counting.
+
+TIM8 CH4:  Pin PC9 is used by the microSD card (MicroSDCard_D1) and I2S
+(I2S_CKIN) but can be completely disconnected from both by opening JP16.
+
+  CONFIGURATION:
+
+    CONFIG_STM32_TIM8=y
+    CONFIG_PWM=n
+    CONFIG_PWM_PULSECOUNT=y
+    CONFIG_STM32_TIM8_PWM=y
+    CONFIG_STM32_TIM8_CHANNEL=4
+
+  ACCESS:
+
+    Daughterboard Extension Connector, CN3, pin 17
+    Ground is available on CN3, pin1
+
+CAN
+===
+
+Connector 10 (CN10) is DB-9 male connector that can be used with CAN1 or CAN2.
+
+  JP10 connects CAN1_RX or CAN2_RX to the CAN transceiver
+  JP3 connects CAN1_TX or CAN2_TX to the CAN transceiver
+
+CAN signals are then available on CN10 pins:
+
+  CN10 Pin 7 = CANH
+  CN10 Pin 2 = CANL
+
+Mapping to STM32 GPIO pins:
+
+  PD0   = FSMC_D2 & CAN1_RX
+  PD1   = FSMC_D3 & CAN1_TX
+  PB13  = ULPI_D6 & CAN2_TX
+  PB5   = ULPI_D7 & CAN2_RX
+
+Configuration Options:
+
+  CONFIG_CAN - Enables CAN support (one or both of CONFIG_STM32_CAN1 or
+    CONFIG_STM32_CAN2 must also be defined)
+  CONFIG_CAN_EXTID - Enables support for the 29-bit extended ID.  Default
+    Standard 11-bit IDs.
+ CONFIG_CAN_FIFOSIZE - The size of the circular buffer of CAN messages.
+    Default: 8
+  CONFIG_CAN_NPENDINGRTR - The size of the list of pending RTR requests.
+    Default: 4
+
+  CONFIG_STM32_CAN1 - Enable support for CAN1
+  CONFIG_CAN1_BAUD - CAN1 BAUD rate.  Required if CONFIG_STM32_CAN1 is defined.
+  CONFIG_STM32_CAN2 - Enable support for CAN2
+  CONFIG_CAN2_BAUD - CAN1 BAUD rate.  Required if CONFIG_STM32_CAN2 is defined.
+  CONFIG_CAN_TSEG1 - The number of CAN time quanta in segment 1. Default: 6
+  CONFIG_CAN_TSEG2 - the number of CAN time quanta in segment 2. Default: 7
+  CONFIG_CAN_REGDEBUG - If CONFIG_DEBUG is set, this will generate an
+    dump of all CAN registers.
+
+FPU
+===
+
+FPU Configuration Options
+-------------------------
+
+There are two version of the FPU support built into the STM32 port.
+
+1. Lazy Floating Point Register Save.
+
+   This is an untested implementation that saves and restores FPU registers
+   only on context switches.  This means: (1) floating point registers are
+   not stored on each context switch and, hence, possibly better interrupt
+   performance.  But, (2) since floating point registers are not saved,
+   you cannot use floating point operations within interrupt handlers.
+
+   This logic can be enabled by simply adding the following to your .config
+   file:
+
+   CONFIG_ARCH_FPU=y
+
+2. Non-Lazy Floating Point Register Save
+
+   Mike Smith has contributed an extensive re-write of the ARMv7-M exception
+   handling logic. This includes verified support for the FPU.  These changes
+   have not yet been incorporated into the mainline and are still considered
+   experimental.  These FPU logic can be enabled with:
+
+   CONFIG_ARCH_FPU=y
+   CONFIG_ARMV7M_CMNVECTOR=y
+
+   You will probably also changes to the scripts/ld.script in if this option is selected.
+   This should work:
+
+   -ENTRY(_stext)
+   +ENTRY(__start)         /* Treat __start as the anchor for dead code stripping */
+   +EXTERN(_vectors)       /* Force the vectors to be included in the output */
+
+CFLAGS
+------
+
+Only the Atollic toolchain has built-in support for the Cortex-M4 FPU.  You will see
+the following lines in each Make.defs file:
+
+  ifeq ($(CONFIG_STM32_ATOLLIC_LITE),y)
+    # Atollic toolchain under Windows
+    ...
+  ifeq ($(CONFIG_ARCH_FPU),y)
+    ARCHCPUFLAGS = -mcpu=cortex-m4 -mthumb -march=armv7e-m -mfpu=fpv4-sp-d16 -mfloat-abi=hard
+  else
+    ARCHCPUFLAGS = -mcpu=cortex-m3 -mthumb -mfloat-abi=soft
+  endif
+  endif
+
+If you are using a toolchain other than the Atollic toolchain, then to use the FPU
+you will also have to modify the CFLAGS to enable compiler support for the ARMv7-M
+FPU.  As of this writing, there are not many GCC toolchains that will support the
+ARMv7-M FPU.
+
+As a minimum you will need to add CFLAG options to (1) enable hardware floating point
+code generation, and to (2) select the FPU implementation.  You might try the same

+Configuration Changes
+---------------------
+
+Below are all of the configuration changes that I had to make to configs/stm3240g-eval/nsh2
+in order to successfully build NuttX using the Atollic toolchain WITH FPU support:
+
+  -CONFIG_ARCH_FPU=n              : Enable FPU support
+  +CONFIG_ARCH_FPU=y
+
+  -CONFIG_STM32_CODESOURCERYW=y   : Disable the CodeSourcery toolchain
+  +CONFIG_STM32_CODESOURCERYW=n
+
+  -CONFIG_STM32_ATOLLIC_LITE=n   : Enable *one* the Atollic toolchains
+   CONFIG_STM32_ATOLLIC_PRO=n
+  -CONFIG_STM32_ATOLLIC_LITE=y   : The "Lite" version, OR
+   CONFIG_STM32_ATOLLIC_PRO=y    : The "Pro" version (not both)
+
+  -CONFIG_INTELHEX_BINARY=y       : Suppress generation FLASH download formats
+  +CONFIG_INTELHEX_BINARY=n       : (Only necessary with the "Lite" version)
+
+  -CONFIG_HAVE_CXX=y              : Suppress generation of C++ code
+  +CONFIG_HAVE_CXX=n              : (Only necessary with the "Lite" version)
+
+See the section above on Toolchains, NOTE 2, for explanations for some of
+the configuration settings.  Some of the usual settings are just not supported
+by the "Lite" version of the Atollic toolchain.
+
+FSMC SRAM
+=========
+
+On-board SRAM
+-------------
+
+A 16 Mbit SRAM is connected to the STM32F407IGH6 FSMC bus which shares the same
+I/Os with the CAN1 bus. Jumper settings:
+
+  JP1: Connect PE4 to SRAM as A20
+  JP2: onnect PE3 to SRAM as A19
+
+JP3 and JP10 must not be fitted for SRAM and LCD application.  JP3 and JP10
+select CAN1 or CAN2 if fitted; neither if not fitted.
+
+The on-board SRAM can be configured by setting
+
+  CONFIG_STM32_FSMC=y
+  CONFIG_STM32_FSMC_SRAM=y
+  CONFIG_HEAP2_BASE=0x64000000
+  CONFIG_HEAP2_SIZE=2097152
+  CONFIG_MM_REGIONS=2 (or =3, see below)
+
+Configuration Options
+---------------------
+Internal SRAM is available in all members of the STM32 family. The F4 family
+also contains internal CCM SRAM.  This SRAM is different because it cannot
+be used for DMA.  So if DMA needed, then the following should be defined
+to exclude CCM SRAM from the heap:
+
+  CONFIG_STM32_CCMEXCLUDE    : Exclude CCM SRAM from the HEAP
+
+In addition to internal SRAM, SRAM may also be available through the FSMC.
+In order to use FSMC SRAM, the following additional things need to be
+present in the NuttX configuration file:
+
+  CONFIG_STM32_FSMC=y        : Enables the FSMC
+  CONFIG_STM32_FSMC_SRAM=y   : Indicates that SRAM is available via the
+                               FSMC (as opposed to an LCD or FLASH).
+  CONFIG_HEAP2_BASE          : The base address of the SRAM in the FSMC
+                               address space
+  CONFIG_HEAP2_SIZE          : The size of the SRAM in the FSMC
+                               address space
+  CONFIG_MM_REGIONS          : Must be set to a large enough value to
+                               include the FSMC SRAM
+
+SRAM Configurations

+There are 4 possible SRAM configurations:
+
+  Configuration 1. System SRAM (only)
+                   CONFIG_MM_REGIONS == 1

+                   CONFIG_STM32_CCMEXCLUDE NOT defined
+  Configuration 3. System SRAM and FSMC SRAM
+                   CONFIG_MM_REGIONS == 2
+                   CONFIG_STM32_FSMC_SRAM defined
+                   CONFIG_STM32_CCMEXCLUDE defined
+  Configuration 4. System SRAM, CCM SRAM, and FSMC SRAM
+                   CONFIG_MM_REGIONS == 3
+                   CONFIG_STM32_FSMC_SRAM defined
+                   CONFIG_STM32_CCMEXCLUDE NOT defined
+I/O Expanders

+
+The STM3240G-EVAL has two STMPE811QTR I/O expanders on board both connected to
+the STM32 via I2C1.  They share a common interrupt line: PI2.

+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until

+  is defined (as above) then the following may also be defined to indicate that
+  the timer is intended to be used for pulsed output modulation, ADC conversion,
+  or DAC conversion. Note that ADC/DAC require two definition:  Not only do you have
+  to assign the timer (n) for used by the ADC or DAC, but then you also have to
+  configure which ADC or DAC (m) it is assigned to.
+

+
+Configurations
+==============
+
+Each STM3240G-EVAL configuration is maintained in a sudirectory and
+can be selected as follow:
+
+    cd tools
+    ./configure.sh stm3240g-eval/<subdir>
+    cd -
+    . ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  dhcpd:
+  -----
+
+    This builds the DCHP server using the apps/examples/dhcpd application
+    (for execution from FLASH.) See apps/examples/README.txt for information
+    about the dhcpd example.  The server address is 10.0.0.1 and it serves
+    IP addresses in the range 10.0.0.2 through 10.0.0.17 (all of which, of
+    course, are configurable).
+
+    CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+
+  discover:
+  --------
+    This configuration exercises netutils/discover utility using
+    apps/exmaples/discover.  This example initializes and starts the UDP
+    discover daemon. This daemon is useful for discovering devices in
+    local networks, especially with DHCP configured devices.  It listens
+    for UDP broadcasts which also can include a device class so that
+    groups of devices can be discovered. It is also possible to address all
+    classes with a kind of broadcast discover.
+
+    Configuration settings that you may need to change for your
+    environment:

+
+  nettest:
+  -------
+
+    This configuration directory may be used to verify networking performance
+    using the STM32's Ethernet controller. It uses apps/examples/nettest to excercise the
+    TCP/IP network.
+
+    CONFIG_EXAMPLE_NETTEST_SERVER=n                       : Target is configured as the client
+    CONFIG_EXAMPLE_NETTEST_PERFORMANCE=y                  : Only network performance is verified.
+    CONFIG_EXAMPLE_NETTEST_IPADDR=(10<<24|0<<16|0<<8|2)   : Target side is IP: 10.0.0.2
+    CONFIG_EXAMPLE_NETTEST_DRIPADDR=(10<<24|0<<16|0<<8|1) : Host side is IP: 10.0.0.1
+    CONFIG_EXAMPLE_NETTEST_CLIENTIP=(10<<24|0<<16|0<<8|1) : Server address used by which ever is client.
+
+  nsh:
+  ---
+    Configures the NuttShell (nsh) located at apps/examples/nsh.  The
+    Configuration enables both the serial and telnet NSH interfaces.
+
+    CONFIG_STM32_CODESOURCERYW=y              : CodeSourcery under Windows
+    CONFIG_NSH_DHCPC=n                        : DHCP is disabled
+    CONFIG_NSH_IPADDR=(10<<24|0<<16|0<<8|2)   : Target IP address 10.0.0.2
+    CONFIG_NSH_DRIPADDR=(10<<24|0<<16|0<<8|1) : Host IP address 10.0.0.1
+
+    NOTES:
+    1. This example assumes that a network is connected.  During its
+       initialization, it will try to negotiate the link speed.  If you have
+       no network connected when you reset the board, there will be a long
+       delay (maybe 30 seconds?) before anything happens.  That is the timeout
+       before the networking finally gives up and decides that no network is
+       available.
+
+    2. This example supports the ADC test (apps/examples/adc) but this must
+       be manually enabled by selecting:
+
+       CONFIG_ADC=y             : Enable the generic ADC infrastructure
+       CONFIG_STM32_ADC3=y      : Enable ADC3
+       CONFIG_STM32_TIM1=y      : Enable Timer 1
+       CONFIG_STM32_TIM1_ADC=y  : Indicate that timer 1 will be used to trigger an ADC
+       CONFIG_STM32_TIM1_ADC3=y : Assign timer 1 to drive ADC3 sampling
+       CONFIG_STM32_ADC3_SAMPLE_FREQUENCY=100 : Select a sampling frequency
+
+       See also apps/examples/README.txt
+
+       General debug for analog devices (ADC/DAC):
+
+       CONFIG_DEBUG_ANALOG
+
+    3. This example supports the PWM test (apps/examples/pwm) but this must
+       be manually enabled by selecting eeither
+
+       CONFIG_PWM=y                : Enable the generic PWM infrastructure
+       CONFIG_PWM_PULSECOUNT=n     : Disable to support for TIM1/8 pulse counts
+       CONFIG_STM32_TIM4=y         : Enable TIM4
+       CONFIG_STM32_TIM4_PWM=y     : Use TIM4 to generate PWM output
+       CONFIG_STM32_TIM4_CHANNEL=2 : Select output on TIM4, channel 2
+
+       If CONFIG_STM32_FSMC is disabled, output will appear on CN3, pin 32.
+       Ground is available on CN3, pin1.
+
+       Or..
+
+       CONFIG_PWM=y                : Enable the generic PWM infrastructure
+       CONFIG_PWM_PULSECOUNT=y     : Enable to support for TIM1/8 pulse counts
+       CONFIG_STM32_TIM8=y         : Enable TIM8
+       CONFIG_STM32_TIM8_PWM=y     : Use TIM8 to generate PWM output
+       CONFIG_STM32_TIM8_CHANNEL=4 : Select output on TIM8, channel 4
+
+       If CONFIG_STM32_FSMC is disabled, output will appear on CN3, pin 17
+       Ground is available on CN23 pin1.
+
+       See also include/board.h and apps/examples/README.txt
+
+       Special PWM-only debug options:
+
+       CONFIG_DEBUG_PWM
+
+    4. This example supports the CAN loopback test (apps/examples/can) but this
+       must be manually enabled by selecting:
+
+       CONFIG_CAN=y             : Enable the generic CAN infrastructure
+       CONFIG_CAN_EXID=y or n   : Enable to support extended ID frames
+       CONFIG_STM32_CAN1=y      : Enable CAN1
+       CONFIG_CAN_LOOPBACK=y    : Enable CAN loopback mode
+
+       See also apps/examples/README.txt
+
+       Special CAN-only debug options:
+
+       CONFIG_DEBUG_CAN
+       CONFIG_CAN_REGDEBUG
+
+    5. This example can support an FTP client.  In order to build in FTP client
+       support simply uncomment the following lines in the appconfig file (before
+       configuring) or in the apps/.config file (after configuring):
+
+       #CONFIGURED_APPS += netutils/ftpc
+       #CONFIGURED_APPS += examples/ftpc
+
+    6. This example can support an FTP server.  In order to build in FTP server
+       support simply uncomment the following lines in the appconfig file (before
+       configuring) or in the apps/.config file (after configuring):
+
+       #CONFIGURED_APPS += netutils/ftpd
+       #CONFIGURED_APPS += examples/ftpd
+
+       And enable poll() support in the NuttX configuration file:
+
+       CONFIG_DISABLE_POLL=n
+
+    7. This example supports the watchdog timer test (apps/examples/watchdog)
+       but this must be manually enabled by selecting:
+
+       CONFIG_WATCHDOG=y         : Enables watchdog timer driver support
+       CONFIG_STM32_WWDG=y       : Enables the WWDG timer facility, OR
+       CONFIG_STM32_IWDG=y       : Enables the IWDG timer facility (but not both)
+
+       The WWDG watchdog is driven off the (fast) 42MHz PCLK1 and, as result,
+       has a maximum timeout value of 49 milliseconds.  For WWDG watchdog, you
+       should also add the fillowing to the configuration file:
+
+       CONFIG_EXAMPLES_WATCHDOG_PINGDELAY=20
+       CONFIG_EXAMPLES_WATCHDOG_TIMEOUT=49
+
+       The IWDG timer has a range of about 35 seconds and should not be an issue.
+
+    7. Adding LCD and graphics support:
+
+       appconfig (apps/.config):  Enable the application configurations that you
+       want to use.  Asexamples:
+
+       CONFIGURED_APPS += examples/nx       : Pick one or more
+       CONFIGURED_APPS += examples/nxhello  :
+       CONFIGURED_APPS += examples/nximage  :
+       CONFIGURED_APPS += examples/nxlines  :
+
+       defconfig (nuttx/.config):
+
+       CONFIG_STM32_FSMC=y                  : FSMC support is required for the LCD
+       CONFIG_NX=y                          : Enable graphics suppport
+       CONFIG_MM_REGIONS=3                  : When FSMC is enabled, so is the on-board SRAM memory region
+
+    8. USB OTG FS Device or Host Support
+ 
+       CONFIG_USBDEV          - Enable USB device support, OR
+       CONFIG_USBHOST         - Enable USB host support
+       CONFIG_STM32_OTGFS     - Enable the STM32 USB OTG FS block
+       CONFIG_STM32_SYSCFG    - Needed
+       CONFIG_SCHED_WORKQUEUE - Worker thread support is required
+
+    9. USB OTG FS Host Support.  The following changes will enable support for
+       a USB host on the STM32F4Discovery, including support for a mass storage
+       class driver:
+
+       CONFIG_USBDEV=n          - Make sure tht USB device support is disabled
+       CONFIG_USBHOST=y         - Enable USB host support
+       CONFIG_STM32_OTGFS=y     - Enable the STM32 USB OTG FS block
+       CONFIG_STM32_SYSCFG=y    - Needed for all USB OTF FS support
+       CONFIG_SCHED_WORKQUEUE=y - Worker thread support is required for the mass
+                                  storage class driver.
+       CONFIG_NSH_ARCHINIT=y    - Architecture specific USB initialization
+                                  is needed for NSH
+       CONFIG_FS_FAT=y          - Needed by the USB host mass storage class.
+
+       With those changes, you can use NSH with a FLASH pen driver as shown
+       belong.  Here NSH is started with nothing in the USB host slot:
+
+       NuttShell (NSH) NuttX-x.yy
+       nsh> ls /dev
+       /dev:
+        console
+        null
+        ttyS0
+
+       After inserting the FLASH drive, the /dev/sda appears and can be
+       mounted like this:
+
+       nsh> ls /dev
+       /dev:
+        console
+        null
+        sda
+        ttyS0
+       nsh> mount -t vfat /dev/sda /mnt/stuff
+       nsh> ls /mnt/stuff
+       /mnt/stuff:
+        -rw-rw-rw-   16236 filea.c
+
+       And files on the FLASH can be manipulated to standard interfaces:
+
+       nsh> echo "This is a test" >/mnt/stuff/atest.txt
+       nsh> ls /mnt/stuff
+       /mnt/stuff:
+        -rw-rw-rw-   16236 filea.c
+        -rw-rw-rw-      16 atest.txt
+       nsh> cat /mnt/stuff/atest.txt
+       This is a test
+       nsh> cp /mnt/stuff/filea.c fileb.c
+       nsh> ls /mnt/stuff
+       /mnt/stuff:
+        -rw-rw-rw-   16236 filea.c
+        -rw-rw-rw-      16 atest.txt
+        -rw-rw-rw-   16236 fileb.c
+
+       To prevent data loss, don't forget to un-mount the FLASH drive
+       before removing it:
+
+       nsh> umount /mnt/stuff
+
+    11. This configuration requires that jumper JP22 be set to enable RS-232
+       operation.
+
+  nsh2:
+  -----
+
+    This is an alternative NSH configuration.  One limitation of the STM3240G-EVAL
+    board is that you cannot have both a UART-based NSH console and SDIO support.
+    The nsh2 differs from the nsh configuration in the following ways:
+
+    -CONFIG_STM32_USART3=y      : USART3 is disabled
+    +CONFIG_STM32_USART3=n
+
+    -CONFIG_STM32_SDIO=n        : SDIO is enabled
+    +CONFIG_STM32_SDIO=y
+
+    Logically, these are the only differences:  This configuration has SDIO (and
+    the SD card) enabled and the serial console disabled. There is ONLY a
+    Telnet console!.
+
+    There are some special settings to make life with only a Telnet
+
+    CONFIG_SYSLOG=y - Enables the System Logging feature.
+    CONFIG_RAMLOG=y - Enable the RAM-based logging feature.
+    CONFIG_RAMLOG_CONSOLE=y - Use the RAM logger as the default console.
+      This means that any console output from non-Telnet threads will
+      go into the circular buffer in RAM.
+    CONFIG_RAMLOG_SYSLOG - This enables the RAM-based logger as the
+      system logger.  This means that (1) in addition to the console
+      output from other tasks, ALL of the debug output will also to
+      to the circular buffer in RAM, and (2) NSH will now support a
+      command called 'dmesg' that can be used to dump the RAM log.
+
+    There are a few other configuration differences as necessary to support
+    this different device configuration. Just the do the 'diff' if you are
+    curious.
+
+    NOTES:
+    1. See the notes for the nsh configuration.  Most also apply to the nsh2
+       configuration.  Like the nsh configuration, this configuration can
+       be modified to support a variety of additional tests.
+
+    2. RS-232 is disabled, but Telnet is still available for use as a console.
+       Since RS-232 and SDIO use the same pins (one controlled by JP22), RS232
+       and SDIO cannot be used concurrently.
+
+    3. This configuration requires that jumper JP22 be set to enable SDIO
+       operation.  To enable MicroSD Card, which shares same I/Os with RS-232,
+       JP22 is not fitted.
+
+    4. In order to use SDIO without overruns, DMA must be used.  The STM32 F4
+       has 192Kb of SRAM in two banks:  112Kb of "system" SRAM located at
+       0x2000:0000 and 64Kb of "CCM" SRAM located at 0x1000:0000. It appears
+       that you cannot perform DMA from CCM SRAM.  The work around that I have now
+       is simply to omit the 64Kb of CCM SRAM from the heap so that all memory is
+       allocated from System SRAM.  This is done by setting:
+
+       CONFIG_MM_REGIONS=1
+
+       Then DMA works fine. The downside is, of course, is that we lose 64Kb
+       of precious SRAM.
+
+    5. Another SDIO/DMA issue.  This one is probably a software bug.  This is
+       the bug as stated in the TODO list:
+
+       "If you use a large I/O buffer to access the file system, then the
+        MMCSD driver will perform multiple block SD transfers.  With DMA
+        ON, this seems to result in CRC errors detected by the hardware
+        during the transfer.  Workaround:  CONFIG_MMCSD_MULTIBLOCK_DISABLE=y"
+
+       For this reason, CONFIG_MMCSD_MULTIBLOCK_DISABLE=y appears in the defconfig
+       file.
+
+    6. Another DMA-related concern.  I see this statement in the reference
+       manual:  "The burst configuration has to be selected in order to respect
+       the AHB protocol, where bursts must not cross the 1 KB address boundary
+       because the minimum address space that can be allocated to a single slave
+       is 1 KB. This means that the 1 KB address boundary should not be crossed
+       by a burst block transfer, otherwise an AHB error would be generated,
+       that is not reported by the DMA registers."
+
+       There is nothing in the DMA driver to prevent this now.
+
+  nxconsole:
+  ----------
+    This is yet another NSH configuration.  This NSH configuration differs
+    from the others, however, in that it uses the NxConsole driver to host
+    the NSH shell.
+
+    Some of the differences in this configuration and the normal nsh configuration
+    include these settings in the defconfig file:
+
+    These select NX Multi-User mode:
+
+      CONFG_NX_MULTIUSER=y
+      CONFIG_DISABLE_MQUEUE=n
+
+    The following definition in the defconfig file to enables the NxConsole
+    driver:
+
+      CONFIG_NXCONSOLE=y
+
+    The appconfig file selects examples/nxconsole instead of examples/nsh:
+
+      CONFIGURED_APPS += examples/nxconsole
+
+    Other configuration settings:
+
+      CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+      CONFIG_LCD_LANDSCAPE=y        : 320x240 landscape
+
+  nxwm
+  ----
+    This is a special configuration setup for the NxWM window manager
+    UnitTest.  The NxWM window manager can be found here:
+
+      trunk/NxWidgets/nxwm
+
+    The NxWM unit test can be found at:
+
+      trunk/NxWidgets/UnitTests/nxwm
+
+    Documentation for installing the NxWM unit test can be found here:
+
+      trunk/NxWidgets/UnitTests/README.txt
+
+    Here is the quick summary of the build steps:
+
+    1. Intall the nxwm configuration
+
+       $ cd ~/nuttx/trunk/nuttx/tools
+       $ ./configure.sh stm3240g-eval/nxwm
+
+    2. Make the build context (only)
+
+       $ cd ..
+       $ . ./setenv.sh
+       $ make context
+       ...
+
+    3. Install the nxwm unit test
+
+       $ cd ~/nuttx/trunk/NxWidgets
+       $ tools/install.sh ~/nuttx/trunk/apps nxwm
+       Creating symbolic link
+        - To ~/nuttx/trunk/NxWidgets/UnitTests/nxwm
+        - At ~/nuttx/trunk/apps/external
+
+    4. Build the NxWidgets library
+
+       $ cd ~/nuttx/trunk/NxWidgets/libnxwidgets
+       $ make TOPDIR=~/nuttx/trunk/nuttx
+       ...
+
+    5. Build the NxWM library
+
+       $ cd ~/nuttx/trunk/NxWidgets/nxwm
+       $ make TOPDIR=~//nuttx/trunk/nuttx
+       ...
+
+    6. Built NuttX with the installed unit test as the application
+
+       $ cd ~/nuttx/trunk/nuttx
+       $ make
+
+  ostest:
+  ------
+    This configuration directory, performs a simple OS test using
+    examples/ostest.  By default, this project assumes that you are
+    using the DFU bootloader.
+
+      CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+
+    If you use the Atollic toolchain, then the FPU test can be enabled in the
+    examples/ostest by adding the following your NuttX configuration file:
+
+     -CONFIG_ARCH_FPU=n              : Enable FPU support
+     +CONFIG_ARCH_FPU=y
+
+     -CONFIG_STM32_CODESOURCERYW=y   : Disable the CodeSourcery toolchain
+     +CONFIG_STM32_CODESOURCERYW=n
+
+     -CONFIG_STM32_ATOLLIC_LITE=n   : Enable *one* the Atollic toolchains
+      CONFIG_STM32_ATOLLIC_PRO=n
+     -CONFIG_STM32_ATOLLIC_LITE=y   : The "Lite" version, OR
+      CONFIG_STM32_ATOLLIC_PRO=n    : The "Pro" version (only one)
+
+     -CONFIG_INTELHEX_BINARY=y       : Suppress generation FLASH download formats
+     +CONFIG_INTELHEX_BINARY=n       : (Only necessary with the "Lite" version)
+
+     -CONFIG_HAVE_CXX=y              : Suppress generation of C++ code
+     +CONFIG_HAVE_CXX=n              : (Only necessary with the "Lite" version)
+
+     -CONFIG_SCHED_WAITPID=y         : Enable the waitpid() API needed by the FPU test
+     +CONFIG_SCHED_WAITPID=n
+
+    The FPU test also needs to know the size of the FPU registers save area in
+    bytes (see arch/arm/include/armv7-m/irq_lazyfpu.h):
+
+     +CONFIG_EXAMPLES_OSTEST_FPUSIZE=(4*33)
+
+  telnetd:
+  --------
+
+    A simple test of the Telnet daemon(see apps/netutils/README.txt,
+    apps/examples/README.txt, and apps/examples/telnetd).  This is
+    the same daemon that is used in the nsh configuration so if you
+    use NSH, then you don't care about this.  This test is good for
+    testing the Telnet daemon only because it works in a simpler
+    environment than does the nsh configuration.
+
+  xmlrpc
+  ------
+
+    An example configuration for the Embeddable Lightweight XML-RPC
+    Server at apps/examples/xmlrpc. See http://www.drdobbs.com/web-development/\
+    an-embeddable-lightweight-xml-rpc-server/184405364 for more info.

+ *
+ *   General transaction rules.  The requested AHB transaction data size can be 8-,
+ *   16- or 32-bit wide whereas the SRAM has a fixed 16-bit data width. Some simple

+ *
+ *   Case 1: AHB transaction width and SRAM data width are equal
+ *     There is no issue in this case.
+ *   Case 2: AHB transaction size is greater than the memory size
+ *     In this case, the FSMC splits the AHB transaction into smaller consecutive
+ *     memory accesses in order to meet the external data width.
+ *   Case 3: AHB transaction size is smaller than the memory size.
+ *     SRAM supports the byte select feature.
+ *     a) FSMC allows write transactions accessing the right data through its
+ *        byte lanes (NBL[1:0])
+ *     b) Read transactions are allowed (the controller reads the entire memory
+ *        word and uses the needed byte only). The NBL[1:0] are always kept low
+ *        during read transactions.

+ *   NOR/SRAM2 base address (0x64000000)
+ *
+ *   General transaction rules.  The requested AHB transaction data size can be 8-,
+ *   16- or 32-bit wide whereas the SRAM has a fixed 16-bit data width. Some simple
+ *   transaction rules must be followed:
+ *
+ *   Case 1: AHB transaction width and SRAM data width are equal
+ *     There is no issue in this case.
+ *   Case 2: AHB transaction size is greater than the memory size
+ *     In this case, the FSMC splits the AHB transaction into smaller consecutive
+ *     memory accesses in order to meet the external data width.
+ *   Case 3: AHB transaction size is smaller than the memory size.
+ *     SRAM supports the byte select feature.
+ *     a) FSMC allows write transactions accessing the right data through its
+ *        byte lanes (NBL[1:0])
+ *     b) Read transactions are allowed (the controller reads the entire memory
+ *        word and uses the needed byte only). The NBL[1:0] are always kept low
+ *        during read transactions.

+ *
+ *   1. Provide logic in stm32_boardinitialize() to configure SPI chip select
+ *      pins.
+ *   2. Provide stm32_spi1/2/3select() and stm32_spi1/2/3status() functions in your
+ *      board-specific logic.  These functions will perform chip selection and
+ *      status operations using GPIOs in the way your board is configured.
+ *   3. Add a calls to up_spiinitialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by up_spiinitialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling
+ *      mmcsd_spislotinitialize(), for example, will bind the SPI driver to

+Development Environment
+=======================
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment because the Raisonance R-Link emulatator and some RIDE7 development tools
+  were used and those tools works only under Windows.
+
+GNU Toolchain Options
+=====================
+
+  Toolchain Configurations
+  ------------------------
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The Atollic Toolchain, 
+  3. The devkitARM GNU toolchain,
+  4. Raisonance GNU toolchain, or
+  5. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the CodeSourcery toolchain for Windows.  To use
+  the Atollic, devkitARM, Raisonance GNU, or NuttX buildroot toolchain, you simply need to
+  add one of the following configuration options to your .config (or defconfig)
+  file:
+
+    CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_STM32_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_STM32_ATOLLIC_LITE=y   : The free, "Lite" version of Atollic toolchain under Windows
+    CONFIG_STM32_ATOLLIC_PRO=y    : The paid, "Pro" version of Atollic toolchain under Windows
+    CONFIG_STM32_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_STM32_RAISONANCE=y     : Raisonance RIDE7 under Windows
+    CONFIG_STM32_BUILDROOT=y      : NuttX buildroot under Linux or Cygwin (default)
+
+  If you change the default toolchain, then you may also have to modify the PATH in
+  the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows), Atollic, devkitARM, and Raisonance toolchains are
+  Windows native toolchains.  The CodeSourcey (for Linux) and NuttX buildroot
+  toolchains are Cygwin and/or Linux native toolchains. There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  The CodeSourcery Toolchain (2009q1)
+  -----------------------------------
+  The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  The Atollic "Pro" and "Lite" Toolchain
+  --------------------------------------
+  One problem that I had with the Atollic toolchains is that the provide a gcc.exe
+  and g++.exe in the same bin/ file as their ARM binaries.  If the Atollic bin/ path
+  appears in your PATH variable before /usr/bin, then you will get the wrong gcc
+  when you try to build host executables.  This will cause to strange, uninterpretable
+  errors build some host binaries in tools/ when you first make.
+
+  Also, the Atollic toolchains are the only toolchains that have built-in support for
+  the FPU in these configurations.  If you plan to use the Cortex-M4 FPU, you will
+  need to use the Atollic toolchain for now.  See the FPU section below for more
+  information.
+
+  The Atollic "Lite" Toolchain
+  ----------------------------
+  The free, "Lite" version of the Atollic toolchain does not support C++ nor
+  does it support ar, nm, objdump, or objdcopy. If you use the Atollic "Lite"
+  toolchain, you will have to set:
+
+    CONFIG_HAVE_CXX=n
+
+  In order to compile successfully.  Otherwise, you will get errors like:
+
+    "C++ Compiler only available in TrueSTUDIO Professional"
+  
+  The make may then fail in some of the post link processing because of some of
+  the other missing tools.  The Make.defs file replaces the ar and nm with
+  the default system x86 tool versions and these seem to work okay.  Disable all
+  of the following to avoid using objcopy:
+
+    CONFIG_RRLOAD_BINARY=n
+    CONFIG_INTELHEX_BINARY=n
+    CONFIG_MOTOROLA_SREC=n
+    CONFIG_RAW_BINARY=n
+
+  devkitARM
+  ---------
+  The devkitARM toolchain includes a version of MSYS make.  Make sure that the
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+====
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project.
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/stm32,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/stm32/stm32_vectors.S.  With RIDE, I have to build NuttX
+  one time from the Cygwin command line in order to obtain the pre-built
+  startup object needed by RIDE.
+
+NuttX buildroot Toolchain
+=========================
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh STM32F4Discovery/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you are
+  building a Cortex-M3 toolchain for Cygwin under Windows.
+
+LEDs
+====
+
+The STM32F4Discovery board has four LEDs; green, organge, red and blue on the
+board.. These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
+defined.  In that case, the usage by the board port is defined in
+include/board.h and src/up_leds.c. The LEDs are used to encode OS-related
+events as follows:
+
+  SYMBOL                Meaning                 LED1*    LED2     LED3     LED4
+                                                green    orange   red      blue
+  -------------------  -----------------------  -------  -------  -------  ------

+  LED_HEAPALLOCATE     Heap has been allocated  OFF      ON       OFF      OFF
+  LED_IRQSENABLED      Interrupts enabled       ON       ON       OFF      OFF
+  LED_STACKCREATED     Idle stack created       OFF      OFF      ON       OFF
+  LED_INIRQ            In an interrupt**        ON       N/C      N/C      OFF
+  LED_SIGNAL           In a signal handler***   N/C      ON       N/C      OFF
+  LED_ASSERTION        An assertion failed      ON       ON       N/C      OFF
+  LED_PANIC            The system has crashed   N/C      N/C      N/C      ON
+  LED_IDLE             STM32 is is sleep mode   (Optional, not used)
+
+  * If LED1, LED2, LED3 are statically on, then NuttX probably failed to boot
+    and these LEDs will give you some indication of where the failure was
+ ** The normal state is LED3 ON and LED1 faintly glowing.  This faint glow
+    is because of timer interupts that result in the LED being illuminated
+    on a small proportion of the time.
+*** LED2 may also flicker normally if signals are processed.
+
+PWM
+===
+
+The STM32F4Discovery has no real on-board PWM devices, but the board can be
+configured to output a pulse train using TIM4 CH2 on PD3.  This pin is
+available next to the audio jack.

+
+Quadrature Encode Timer Inputs
+------------------------------
+
+If enabled (by setting CONFIG_QENCODER=y), then quadrature encoder will
+use either TIM2 or TIM8 (see nsh/defconfig).  If TIM2 is selected, the input 
+pins PA15 and PA1 for CH1 and CH2, respectively).  If TIM8 is selected, then
+PC6 and PI5 will be used for CH1 and CH2  (see include board.h for pin
+definitions).
+
+FPU
+===
+
+FPU Configuration Options
+-------------------------
+
+There are two version of the FPU support built into the STM32 port.
+
+1. Lazy Floating Point Register Save.
+
+   This is an untested implementation that saves and restores FPU registers
+   only on context switches.  This means: (1) floating point registers are
+   not stored on each context switch and, hence, possibly better interrupt
+   performance.  But, (2) since floating point registers are not saved,
+   you cannot use floating point operations within interrupt handlers.
+
+   This logic can be enabled by simply adding the following to your .config
+   file:
+
+   CONFIG_ARCH_FPU=y
+
+2. Non-Lazy Floating Point Register Save
+
+   Mike Smith has contributed an extensive re-write of the ARMv7-M exception
+   handling logic. This includes verified support for the FPU.  These changes
+   have not yet been incorporated into the mainline and are still considered
+   experimental.  These FPU logic can be enabled with:
+
+   CONFIG_ARCH_FPU=y
+   CONFIG_ARMV7M_CMNVECTOR=y
+
+   You will probably also changes to the ld.script in if this option is selected.
+   This should work:
+
+   -ENTRY(_stext)
+   +ENTRY(__start)         /* Treat __start as the anchor for dead code stripping */
+   +EXTERN(_vectors)       /* Force the vectors to be included in the output */
+
+CFLAGS
+------
+
+Only the Atollic toolchain has built-in support for the Cortex-M4 FPU.  You will see
+the following lines in each Make.defs file:
+
+  ifeq ($(CONFIG_STM32_ATOLLIC_LITE),y)
+    # Atollic toolchain under Windows
+    ...
+  ifeq ($(CONFIG_ARCH_FPU),y)
+    ARCHCPUFLAGS = -mcpu=cortex-m4 -mthumb -march=armv7e-m -mfpu=fpv4-sp-d16 -mfloat-abi=hard
+  else
+    ARCHCPUFLAGS = -mcpu=cortex-m3 -mthumb -mfloat-abi=soft
+  endif
+  endif
+
+If you are using a toolchain other than the Atollic toolchain, then to use the FPU
+you will also have to modify the CFLAGS to enable compiler support for the ARMv7-M
+FPU.  As of this writing, there are not many GCC toolchains that will support the
+ARMv7-M FPU.  
+
+As a minimum you will need to add CFLAG options to (1) enable hardware floating point
+code generation, and to (2) select the FPU implementation.  You might try the same
+options as used with the Atollic toolchain in the Make.defs file:
+
+  ARCHCPUFLAGS = -mcpu=cortex-m4 -mthumb -march=armv7e-m -mfpu=fpv4-sp-d16 -mfloat-abi=hard
+
+FSMC SRAM
+=========
+
+On-board SRAM
+-------------
+The STM32F4Discovery has no on-board SRAM.  The information here is only for
+reference in case you choose to add some.
+
+Configuration Options
+---------------------
+Internal SRAM is available in all members of the STM32 family. The F4 family
+also contains internal CCM SRAM.  This SRAM is different because it cannot
+be used for DMA.  So if DMA needed, then the following should be defined
+to exclude CCM SRAM from the heap:
+
+  CONFIG_STM32_CCMEXCLUDE    : Exclude CCM SRAM from the HEAP
+
+In addition to internal SRAM, SRAM may also be available through the FSMC.
+In order to use FSMC SRAM, the following additional things need to be
+present in the NuttX configuration file:
+
+  CONFIG_STM32_FSMC=y        : Enables the FSMC
+  CONFIG_STM32_FSMC_SRAM=y   : Indicates that SRAM is available via the
+                               FSMC (as opposed to an LCD or FLASH).
+  CONFIG_HEAP2_BASE          : The base address of the SRAM in the FSMC
+                               address space
+  CONFIG_HEAP2_SIZE          : The size of the SRAM in the FSMC
+                               address space
+  CONFIG_MM_REGIONS          : Must be set to a large enough value to
+                               include the FSMC SRAM 
+
+SRAM Configurations
+-------------------
+There are 4 possible SRAM configurations:
+
+  Configuration 1. System SRAM (only)
+                   CONFIG_MM_REGIONS == 1
+                   CONFIG_STM32_FSMC_SRAM NOT defined
+                   CONFIG_STM32_CCMEXCLUDE defined
+  Configuration 2. System SRAM and CCM SRAM
+                   CONFIG_MM_REGIONS == 2
+                   CONFIG_STM32_FSMC_SRAM NOT defined
+                   CONFIG_STM32_CCMEXCLUDE NOT defined
+  Configuration 3. System SRAM and FSMC SRAM
+                   CONFIG_MM_REGIONS == 2
+                   CONFIG_STM32_FSMC_SRAM defined
+                   CONFIG_STM32_CCMEXCLUDE defined
+  Configuration 4. System SRAM, CCM SRAM, and FSMC SRAM
+                   CONFIG_MM_REGIONS == 3
+                   CONFIG_STM32_FSMC_SRAM defined
+                   CONFIG_STM32_CCMEXCLUDE NOT defined
+
+Configuration Changes
+---------------------
+
+Below are all of the configuration changes that I had to make to configs/stm3240g-eval/nsh2
+in order to successfully build NuttX using the Atollic toolchain WITH FPU support:
+
+  -CONFIG_ARCH_FPU=n              : Enable FPU support
+  +CONFIG_ARCH_FPU=y
+
+  -CONFIG_STM32_CODESOURCERYW=y   : Disable the CodeSourcery toolchain
+  +CONFIG_STM32_CODESOURCERYW=n
+
+  -CONFIG_STM32_ATOLLIC_LITE=n   : Enable *one* the Atollic toolchains
+   CONFIG_STM32_ATOLLIC_PRO=n
+  -CONFIG_STM32_ATOLLIC_LITE=y   : The "Lite" version
+   CONFIG_STM32_ATOLLIC_PRO=n    : The "Pro" version
+
+  -CONFIG_INTELHEX_BINARY=y       : Suppress generation FLASH download formats
+  +CONFIG_INTELHEX_BINARY=n       : (Only necessary with the "Lite" version)
+
+  -CONFIG_HAVE_CXX=y              : Suppress generation of C++ code
+  +CONFIG_HAVE_CXX=n              : (Only necessary with the "Lite" version)
+
+See the section above on Toolchains, NOTE 2, for explanations for some of
+the configuration settings.  Some of the usual settings are just not supported
+by the "Lite" version of the Atollic toolchain.
+
+SSD1289
+=======
+
+I purchased an LCD display on eBay from china.  The LCD is 320x240 RGB565 and
+is based on an SSD1289 LCD controller and an XPT2046 touch IC.  The pin out
+from the 2x16 connect on the LCD is labeled as follows:

+       CONFIG_DRAM_START=0x20000000
+
+    CONFIG_STM32_CCMEXCLUDE - Exclude CCM SRAM from the HEAP
+
+    In addition to internal SRAM, SRAM may also be available through the FSMC.
+    In order to use FSMC SRAM, the following additional things need to be
+    present in the NuttX configuration file:
+
+    CONFIG_STM32_FSMC_SRAM - Indicates that SRAM is available via the
+      FSMC (as opposed to an LCD or FLASH).
+
+    CONFIG_HEAP2_BASE - The base address of the SRAM in the FSMC address space (hex)
+
+    CONFIG_HEAP2_SIZE - The size of the SRAM in the FSMC address space (decimal)
+
+    CONFIG_ARCH_IRQPRIO - The STM32F4Discovery supports interrupt prioritization
+
+       CONFIG_ARCH_IRQPRIO=y
+
+    CONFIG_ARCH_FPU - The STM32F4Discovery supports a floating point unit (FPU)
+
+       CONFIG_ARCH_FPU=y
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+       stack. If defined, this symbol is the size of the interrupt
+        stack in bytes.  If not defined, the user task stacks will be
+      used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.

+  Timer devices may be used for different purposes.  One special purpose is
+  to generate modulated outputs for such things as motor control.  If CONFIG_STM32_TIMn
+  is defined (as above) then the following may also be defined to indicate that
+  the timer is intended to be used for pulsed output modulation, ADC conversion,
+  or DAC conversion. Note that ADC/DAC require two definition:  Not only do you have

+    CONFIG_STM32_TIMn_DACm  Reserve timer n to trigger DACm, n=1,..,14, m=1,..,2
+
+  For each timer that is enabled for PWM usage, we need the following additional
+  configuration settings:
+
+    CONFIG_STM32_TIMx_CHANNEL - Specifies the timer output channel {1,..,4}
+ 
+  NOTE: The STM32 timers are each capable of generating different signals on
+  each of the four channels with different duty cycles.  That capability is
+  not supported by this driver:  Only one output channel per timer.

+Configurations
+==============
+
+Each STM32F4Discovery configuration is maintained in a sudirectory and
+can be selected as follow:
+
+    cd tools
+    ./configure.sh STM32F4Discovery/<subdir>
+    cd -
+    . ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  ostest:
+  ------
+    This configuration directory, performs a simple OS test using
+    examples/ostest.  By default, this project assumes that you are
+    using the DFU bootloader.
+
+    Default toolchain:
+
+    CONFIG_STM32_CODESOURCERYL=y  : CodeSourcery under Linux / Mac OS X
+
+    If you use the Atollic toolchain, then the FPU test can be enabled in the
+    examples/ostest by adding the following your NuttX configuration file:
+
+     -CONFIG_ARCH_FPU=n              : Enable FPU support
+     +CONFIG_ARCH_FPU=y
+
+     -CONFIG_STM32_CODESOURCERYW=y   : Disable the CodeSourcery toolchain
+     +CONFIG_STM32_CODESOURCERYW=n
+
+     -CONFIG_STM32_ATOLLIC_LITE=n   : Enable *one* the Atollic toolchains
+      CONFIG_STM32_ATOLLIC_PRO=n
+     -CONFIG_STM32_ATOLLIC_LITE=y   : The "Lite" version
+      CONFIG_STM32_ATOLLIC_PRO=n    : The "Pro" version
+
+     -CONFIG_INTELHEX_BINARY=y       : Suppress generation FLASH download formats
+     +CONFIG_INTELHEX_BINARY=n       : (Only necessary with the "Lite" version)
+
+     -CONFIG_HAVE_CXX=y              : Suppress generation of C++ code
+     +CONFIG_HAVE_CXX=n              : (Only necessary with the "Lite" version)
+
+     -CONFIG_SCHED_WAITPID=y         : Enable the waitpid() API needed by the FPU test
+     +CONFIG_SCHED_WAITPID=n
+
+    The FPU test also needs to know the size of the FPU registers save area in
+    bytes (see arch/arm/include/armv7-m/irq_lazyfpu.h):
+
+     -CONFIG_EXAMPLES_OSTEST_FPUSIZE=(4*33)
+ 
+  nsh:
+  ---
+    Configures the NuttShell (nsh) located at apps/examples/nsh.  The
+    Configuration enables both the serial and telnet NSH interfaces.
+
+    Default toolchain:
+
+    CONFIG_STM32_CODESOURCERYL=y  : CodeSourcery under Linux / Mac OS X
+
+    NOTES:
+    1. This example supports the PWM test (apps/examples/pwm) but this must
+       be manually enabled by selecting:
+
+       CONFIG_PWM=y              : Enable the generic PWM infrastructure
+       CONFIG_STM32_TIM4=y       : Enable TIM4
+       CONFIG_STM32_TIM4_PWM=y   : Use TIM4 to generate PWM output
+
+       See also apps/examples/README.txt
+
+       Special PWM-only debug options:
+
+       CONFIG_DEBUG_PWM
+
+    2. This example supports the Quadrature Encode test (apps/examples/qencoder)
+       but this must be manually enabled by selecting:
+
+       CONFIG_QENCODER=y         : Enable the generic Quadrature Encoder infrastructure
+       CONFIG_STM32_TIM8=y       : Enable TIM8
+       CONFIG_STM32_TIM2=n       : (Or optionally TIM2)
+       CONFIG_STM32_TIM8_QE=y    : Use TIM8 as the quadrature encoder
+       CONFIG_STM32_TIM2_QE=y    : (Or optionally TIM2)
+
+       See also apps/examples/README.txt
+
+       Special PWM-only debug options:
+
+       CONFIG_DEBUG_QENCODER
+
+    3. This example supports the watchdog timer test (apps/examples/watchdog)
+       but this must be manually enabled by selecting:
+
+       CONFIG_WATCHDOG=y         : Enables watchdog timer driver support
+       CONFIG_STM32_WWDG=y       : Enables the WWDG timer facility, OR
+       CONFIG_STM32_IWDG=y       : Enables the IWDG timer facility (but not both)
+
+       The WWDG watchdog is driven off the (fast) 42MHz PCLK1 and, as result,
+       has a maximum timeout value of 49 milliseconds.  for WWDG watchdog, you
+       should also add the fillowing to the configuration file:
+
+       CONFIG_EXAMPLES_WATCHDOG_PINGDELAY=20
+       CONFIG_EXAMPLES_WATCHDOG_TIMEOUT=49
+
+       The IWDG timer has a range of about 35 seconds and should not be an issue.
+
+     4. USB Support (CDC/ACM device)
+
+        CONFIG_STM32_OTGFS=y      : STM32 OTG FS support
+        CONFIG_USBDEV=y           : USB device support must be enabled
+        CONFIG_CDCACM=y           : The CDC/ACM driver must be built
+        CONFIG_NSH_BUILTIN_APPS=y : NSH built-in application support must be enabled
+
+     5. Using the USB console.
+
+        The STM32F4Discovery NSH configuration can be set up to use a USB CDC/ACM
+        (or PL2303) USB console.  The normal way that you would configure the
+        the USB console would be to change the .config file like this:
+
+        CONFIG_STM32_OTGFS=y      : STM32 OTG FS support
+        CONFIG_DEV_CONSOLE=n      : Inhibit use of /dev/console by other logic
+        CONFIG_USBDEV=y           : USB device support must be enabled
+        CONFIG_CDCACM=y           : The CDC/ACM driver must be built
+        CONFIG_CDCACM_CONSOLE=y   : Enable the CDC/ACM USB console.
+
+        However, that configuration does not work.  It fails early probably because
+        of some dependency on /dev/console before the USB connection is established.
+
+        But there is a work around for this that works better (but has some side
+        effects).  The following configuration will also create a NSH USB console
+        but this version will will use /dev/console.  Instead, it will use the
+        normal /dev/ttyACM0 USB serial device for the console:
+
+        CONFIG_STM32_OTGFS=y      : STM32 OTG FS support
+        CONFIG_USBDEV=y           : USB device support must be enabled
+        CONFIG_CDCACM=y           : The CDC/ACM driver must be built
+        CONFIG_CDCACM_CONSOLE=n   : Done use the CDC/ACM USB console.
+        CONFIG_NSH_USBCONSOLE=y   : Instead use some other USB device for the console
+
+        The particular USB device that is used is:
+
+        CONFIG_NSH_USBCONDEV="/dev/ttyACM0"
+
+        NOTE 1: When you first start the USB console, you have hit ENTER a few
+        times before NSH starts.  The logic does this to prevent sending USB data
+        before there is anything on the host side listening for USB serial input.
+
+        Now the side effects:
+
+        NOTE 2. When any other device other than /dev/console is used for a user
+        interface, linefeeds (\n) will not be expanded to carriage return /
+        linefeeds (\r\n).  You will need to set your terminal program to account
+        for this.
+
+        NOTE 3: /dev/console still exists and still refers to the serial port. So
+        you can still use certain kinds of debug output (see include/debug.h, all
+        of the interfaces based on lib_lowprintf will work in this configuration).
+
+    6. USB OTG FS Host Support.  The following changes will enable support for
+       a USB host on the STM32F4Discovery, including support for a mass storage
+       class driver:
+ 
+       CONFIG_USBDEV=n          - Make sure tht USB device support is disabled
+       CONFIG_USBHOST=y         - Enable USB host support
+       CONFIG_STM32_OTGFS=y     - Enable the STM32 USB OTG FS block
+       CONFIG_STM32_SYSCFG=y    - Needed for all USB OTF FS support
+       CONFIG_SCHED_WORKQUEUE=y - Worker thread support is required for the mass
+                                  storage class driver.
+       CONFIG_NSH_ARCHINIT=y    - Architecture specific USB initialization
+                                  is needed for NSH
+       CONFIG_FS_FAT=y          - Needed by the USB host mass storage class.
+
+       With those changes, you can use NSH with a FLASH pen driver as shown
+       belong.  Here NSH is started with nothing in the USB host slot:
+
+       NuttShell (NSH) NuttX-x.yy
+       nsh> ls /dev
+       /dev:
+        console
+        null
+        ttyS0
+
+       After inserting the FLASH drive, the /dev/sda appears and can be
+       mounted like this:
+
+       nsh> ls /dev
+       /dev:
+        console
+        null
+        sda
+        ttyS0
+       nsh> mount -t vfat /dev/sda /mnt/stuff
+       nsh> ls /mnt/stuff
+       /mnt/stuff:
+        -rw-rw-rw-   16236 filea.c
+
+       And files on the FLASH can be manipulated to standard interfaces:
+
+       nsh> echo "This is a test" >/mnt/stuff/atest.txt
+       nsh> ls /mnt/stuff
+       /mnt/stuff:
+        -rw-rw-rw-   16236 filea.c
+        -rw-rw-rw-      16 atest.txt
+       nsh> cat /mnt/stuff/atest.txt
+       This is a test
+       nsh> cp /mnt/stuff/filea.c fileb.c
+       nsh> ls /mnt/stuff
+       /mnt/stuff:
+        -rw-rw-rw-   16236 filea.c
+        -rw-rw-rw-      16 atest.txt
+        -rw-rw-rw-   16236 fileb.c
+
+       To prevent data loss, don't forget to un-mount the FLASH drive
+       before removing it:
+
+       nsh> umount /mnt/stuff
+

+    An example using the NuttX graphics system (NX).   This example focuses on
+    placing lines on the background in various orientations.
+
+      CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+      CONFIG_LCD_LANDSCAPE=y        : 320x240 landscape orientation
+
+    The STM32F4Discovery board does not have any graphics capability.  This
+    configuration assumes that you have connected an SD1289-based LCD as
+    described about under "SSD1289".  NOTE:  At present, it has not been
+    proven that the STM32F4Discovery can actually drive an LCD.  There are
+    some issues with how some of the dedicated FSMC pins are used on the
+    boards.  This configuration may not be useful and may only serve as
+    an illustration of how to build for th SSD1289 LCD.
+
+    Default toolchain:
+
+      CONFIG_STM32_CODESOURCERYW=y : CodeSourcery under Windows
+
+    NOTE: As of this writing, I have not seen the LCD work!
+
+  pm:
+  --
+    This is a configuration that is used to test STM32 power management, i.e.,
+    to test that the board can go into lower and lower states of power usage
+    as a result of inactivity.  This configuration is based on the nsh2
+    configuration with modifications for testing power management.  This
+    configuration should provide some guideline for power management in your
+    STM32 application.
+
+      CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+
+    CONFIG_PM_CUSTOMINIT and CONFIG_IDLE_CUSTOM are necessary parts of the
+    PM configuration:
+
+      CONFIG_PM_CUSTOMINIT=y
+
+    CONFIG_PM_CUSTOMINIT moves the PM initialization from arch/arm/src/stm32/stm32_pminitialiaze.c
+    to configs/stm3210-eval/src/up_pm.c.  This allows us to support board-
+    specific PM initialization.
+    
+      CONFIG_IDLE_CUSTOM=y
+
+    The bulk of the PM activities occur in the IDLE loop.  The IDLE loop is
+    special because it is what runs when there is no other task running.  Therefore
+    when the IDLE executes, we can be assure that nothing else is going on; this
+    is the ideal condition for doing reduced power management.
+
+    The configuration CONFIG_IDLE_CUSTOM allows us to "steal" the normal STM32
+    IDLE loop (of arch/arm/src/stm32/stm32_idle.c) and replace this with our own
+    custom IDLE loop (at configs/stm3210-eval/src/up_idle.c).
+
+    Here are some additional things to note in the configuration:
+
+      CONFIG_PM_BUTTONS=y
+    
+    CONFIG_PM_BUTTONS enables button support for PM testing.  Buttons can drive
+    EXTI interrupts and EXTI interrrupts can be used to wakeup for certain reduced
+    power modes (STOP mode).  The use of the buttons here is for PM testing purposes
+    only; buttons would normally be part the application code and CONFIG_PM_BUTTONS
+    would not be defined.
+
+      CONFIG_RTC_ALARM=y
+
+    The RTC alarm is used to wake up from STOP mode and to transition to
+    STANDBY mode.  This used of the RTC alarm could conflict with other uses of
+    the RTC alarm in your application.

+ * Description:
+ *   The external functions, stm32_spi1/2/3select and stm32_spi1/2/3status must be
+ *   provided by board-specific logic.  They are implementations of the select
+ *   and status methods of the SPI interface defined by struct spi_ops_s (see
+ *   include/nuttx/spi.h). All other methods (including up_spiinitialize())
+ *   are provided by common STM32 logic.  To use this common SPI logic on your
+ *   board:
+ *
+ *   1. Provide logic in stm32_boardinitialize() to configure SPI chip select
+ *      pins.
+ *   2. Provide stm32_spi1/2/3select() and stm32_spi1/2/3status() functions in your
+ *      board-specific logic.  These functions will perform chip selection and
+ *      status operations using GPIOs in the way your board is configured.
+ *   3. Add a calls to up_spiinitialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by up_spiinitialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling
+ *      mmcsd_spislotinitialize(), for example, will bind the SPI driver to
+ *      the SPI MMC/SD driver).

+Toolchains
+==========
+
+  MPLAB/C32
+  ---------
+
+  I am using the free, "Lite" version of the PIC32MX toolchain available
+  for download from the microchip.com web site.  I am using the Windows
+  version.  The MicroChip toolchain is the only toolchain currently
+  supported in these configurations, but it should be a simple matter to
+  adapt to other toolchains by modifying the Make.defs file include in
+  each configuration.
+
+  C32 Toolchain Options:
+
+    CONFIG_PIC32MX_MICROCHIPW      - MicroChip full toolchain for Windows
+    CONFIG_PIC32MX_MICROCHIPL      - MicroChip full toolchain for Linux
+    CONFIG_PIC32MX_MICROCHIPW_LITE - MicroChip "Lite" toolchain for Windows
+    CONFIG_PIC32MX_MICROCHIPL_LITE - MicroChip "Lite" toolchain for Linux
+
+  NOTE:  The "Lite" versions of the toolchain does not support C++.  Also
+  certain optimization levels are not supported by the "Lite" toolchain.
+
+  MicrochipOpen
+  -------------
+
+  An alternative, build-it-yourself toolchain is available here:
+  http://sourceforge.net/projects/microchipopen/ .  These tools were
+  last updated circa 2010.  NOTE:  C++ support still not available
+  in this toolchain.
+
+  Building MicrochipOpen (on Linux)
+
+  1) Get the build script from this location:
+
+      http://microchipopen.svn.sourceforge.net/viewvc/microchipopen/ccompiler4pic32/buildscripts/trunk/
+
+  2) Build the code using the build script, for example:
+
+      ./build.sh -b v105_freeze
+
+     This will check out the selected branch and build the tools.
+
+  3) Binaries will then be available in a subdirectory with a name something like
+     pic32-v105-freeze-20120622/install-image/bin (depending on the current data
+     and the branch that you selected.
+
+     Note that the tools will have the prefix, mypic32- so, for example, the
+     compiler will be called mypic32-gcc.
+
+  Penguino mips-elf Toolchain
+  ---------------------------
+
+  Another option is the mips-elf toolchain used with the Penguino project.  This
+  is a relatively current mips-elf GCC and should provide free C++ support as
+  well. This toolchain can be downloded from the Penguino website:
+  http://wiki.pinguino.cc/index.php/Main_Page#Download . There is some general
+  information about using the Penguino mips-elf toolchain in this thread:
+  http://tech.groups.yahoo.com/group/nuttx/message/1821
+
+  See also configs/mirtoo/README.txt.  There is an experimental (untested)
+  configuration for the Mirtoo platform in that directory.
+
+  MPLAB/C32 vs MPLABX/X32
+  -----------------------
+
+  It appears that Microchip is phasing out the MPLAB/C32 toolchain and replacing
+  it with MPLABX and XC32.  At present, the XC32 toolchain is *not* compatible
+  with the NuttX build scripts.  Here are some of the issues that I see when trying
+  to build with XC32:
+
+  1) Make.def changes:  You have to change the tool prefix:
+
+     CROSSDEV=xc32-
+
+  2) debug.ld/release.ld:  The like expect some things that are not present in
+     the current linker scripts (or are expected with different names).  Here
+     are some partial fixes:
+
+     Rename:  kseg0_progmem to kseg0_program_mem
+     Rename:  kseg1_datamem to kseg1_data_mem
+
+  Even then, there are more warnings from the linker and some undefined symbols
+  for non-NuttX code that resides in the unused Microchip libraries.  See this
+  email thread at http://tech.groups.yahoo.com/group/nuttx/message/1458 for more
+  information.  You will have to solve at least this undefined symbol problem if
+  you want to used the XC32 toolchain.
+
+  Windows Native Toolchains
+  -------------------------
+  
+  NOTE:  There are several limitations to using a Windows based toolchain in a
+  Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+Loading NuttX with PICkit2
+==========================
+
+  NOTE:  You need a PICKit3 if you plan to use the MPLAB debugger!  The PICKit2
+  can, however, still be used to load programs.  Instructions for the PICKit3
+  are similar.
+
+  Intel Hex Forma Files:
+  ----------------------
+
+    When NuttX is built it will produce two files in the top-level NuttX
+    directory:
+
+    1) nuttx - This is an ELF file, and
+    2) nuttx.hex - This is an Intel Hex format file.  This is controlled by
+       the setting CONFIG_INTELHEX_BINARY in the .config file.
+
+    The PICkit tool wants an Intel Hex format file to burn into FLASH. However,
+    there is a problem with the generated nutt.hex: The tool expects the nuttx.hex
+    file to contain physical addresses.  But the nuttx.hex file generated from the
+    top-level make will have address in the KSEG0 and KSEG1 regions.
+
+  tools/pic32mx/mkpichex:
+  ----------------------
+
+    There is a simple tool in the NuttX tools/pic32mx directory that can be
+    used to solve both issues with the nuttx.hex file.  But, first, you must
+    build the tool:
+
+      cd tools/pic32mx
+      make
+
+    Now you will have an excecutable file call mkpichex (or mkpichex.exe on
+    Cygwin).  This program will take the nutt.hex file as an input, it will
+    convert all of the KSEG0 and KSEG1 addresses to physical address, and
+    it will write the modified file, replacing the original nuttx.hex.
+
+    To use this file, you need to do the following things:
+
+      . ./setenv.sh    # Source setenv.sh.  Among other this, this script
+                       # will add the NuttX tools/pic32mx directory to your
+                       # PATH variable
+      make             # Build nuttx and nuttx.hex
+      mkpichex $PWD    # Convert addresses in nuttx.hex.  $PWD is the path
+                       # to the top-level build directory.  It is the only
+                       # required input to mkpichex.
+
+PIC32MX Configuration Options
+=============================
+
+  General Architecture Settings:
+
+    CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+     be set to:
+
+       CONFIG_ARCH=mips
+
+    CONFIG_ARCH_family - For use in C code:
+
+       CONFIG_ARCH_MIPS=y
+
+    CONFIG_ARCH_architecture - For use in C code:
+
+       CONFIG_ARCH_MIPS32=y
+
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+       CONFIG_ARCH_CHIP=pic32mx
+
+    CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+       chip:
+
+       CONFIG_ARCH_CHIP_PIC32MX440F512H=y
+
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+
+       CONFIG_ARCH_BOARD=sure-pic32mx
+
+    CONFIG_ARCH_DBDP11215 Distinguishes the DB_DP11215 PIC32 Storage 
+      Demo Board
+
+    CONFIG_ARCH_DBDP11212 Distingustes the DB-DP11212 PIC32 General
+      Purpose Demo Board
+
+    CONFIG_ARCH_BOARD_name - For use in C code
+
+       CONFIG_ARCH_BOARD_SUREPIC32MX=y
+
+    CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+       of delay loops
+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_DRAM_SIZE - Describes the installed DRAM (CPU SRAM in this case):
+
+       CONFIG_DRAM_SIZE=(32*1024) (32Kb)
+
+       There is an additional 32Kb of SRAM in AHB SRAM banks 0 and 1.
+
+    CONFIG_DRAM_START - The start address of installed DRAM
+
+       CONFIG_DRAM_START=0xa0000000
+
+    CONFIG_ARCH_IRQPRIO - The PIC32MXx supports interrupt prioritization
+
+       CONFIG_ARCH_IRQPRIO=y
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+       stack. If defined, this symbol is the size of the interrupt
+       stack in bytes.  If not defined, the user task stacks will be
+       used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.

+
+  PIC32MXx USB Host Configuration (the PIC32MX does not support USB Host)
+
+Configurations
+==============
+
+Each PIC32MX configuration is maintained in a sudirectory and can be
+selected as follow:
+
+    cd tools
+    ./configure.sh sure-pic32mx/<subdir>
+    cd -
+    . ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  ostest:
+  =======
+    Description.
+    ------------
+    This configuration directory, performs a simple OS test using
+    apps/examples/ostest.
+
+  nsh:
+  ====
+    Description.
+    ------------
+    Configures the NuttShell (nsh) located at apps/examples/nsh.  The
+    Configuration enables only the serial NSH interface.
+
+    USB Configuations.
+    -----------------
+    Several USB device configurations can be enabled and included
+    as NSH built-in built in functions.  All require the following
+    basic setup in your .config to enable USB device support:
+ 
+      CONFIG_USBDEV=y         : Enable basic USB device support
+      CONFIG_PIC32MX_USBDEV=y : Enable PIC32 USB device support
+
+    examples/usbterm - This option can be enabled by uncommenting
+    the following line in the appconfig file:
+
+      CONFIGURED_APPS += examples/usbterm
+
+    And by enabling one of the USB serial devices:
+
+      CONFIG_PL2303=y         : Enable the Prolifics PL2303 emulation
+      CONFIG_CDCACM=y         : or the CDC/ACM serial driver (not both)
+
+    examples/cdcacm -  The examples/cdcacm program can be included as an 
+    function by uncommenting the following line in the appconfig file:
+    
+      CONFIGURED_APPS += examples/cdcacm
+
+    and defining the following in your .config file:
+
+      CONFIG_CDCACM=y         : Enable the CDCACM device
+
+    examples/usbstorage - There are some hooks in the appconfig file
+    to enable the USB mass storage device.  However, this device cannot
+    work until support for the SD card is also incorporated.
+
+    SD Card Support.
+    ----------------
+    Support for the on-board, SPI-based SD card is available but is
+    not yet functional (at least at the time of this writing).  SD
+    card support can be enabled for testing by simply enabling SPI2
+    support in the configuration file:
+
+      -CONFIG_PIC32MX_SPI2=n
+      +CONFIG_PIC32MX_SPI2=y
+
+    Debug output for testing the SD card can be enabled using:
+
+      -CONFIG_DEBUG_FS=n
+      -CONFIG_DEBUG_SPI=n
+      +CONFIG_DEBUG_FS=y
+      +CONFIG_DEBUG_SPI=y
+
+  usbnsh:
+  =======
+    Description.
+    ------------
+    This is another NSH example.  If differs from the 'nsh' configuration
+    above in that this configurations uses a USB serial device for console
+    I/O.  This configuration was created to support the "DB-DP11212 PIC32
+    General Purpose Demo Board" which has no easily accessible serial port.
+    However, as of this writing, the configuration has set for the
+    "DB_DP11215 PIC32 Storage Demo Board" and has only be testing on that
+    board.
+
+    Comparison to nsh
+    -----------------
+    Below summarizes the key configuration differences between the 'nsh'
+    and the 'upnsh' configurations:
+
+      CONFIG_USBDEV=y               : NuttX USB device support is enabled
+      CONFIG_PIC32MX_USBDEV=y       : The PIC32MX USB device driver is built
+      CONFIG_UART1_SERIAL_CONSOLE=n : There is no serial console
+      CONFIG_UART2_SERIAL_CONSOLE=n :
+      CONFIG_CDCACM=y               : The CDC/ACM serial device class is enabled
+      CONFIG_CDCACM_CONSOLE=y       : The CDC/ACM serial device is the console
+
+    Using the Prolifics PL2303 Emulation
+    ------------------------------------
+    You could also use the non-standard PL2303 serial device instead of
+    the standard CDC/ACM serial device by changing:
+
+      CONFIG_CDCACM=y               : Disable the CDC/ACM serial device class
+      CONFIG_CDCACM_CONSOLE=y       : The CDC/ACM serial device is NOT the console
+      CONFIG_PL2303=y               : The Prolifics PL2303 emulation is enabled
+      CONFIG_PL2303_CONSOLE=y       : The PL2303 serial device is the console
+
+    Why would you want to use a non-standard USB serial driver?  You might
+    to use the PL2303 driver with a Windows host because it should
+    automatically install the PL2303 driver (you might have to go through
+    some effort to get Windows to recognize the CDC/ACM device).

+ *   buttons or up_irqbutton() may be called to register button interrupt
+ *   handlers.
+ *
+ *   After up_buttoninit() has been called, up_buttons() may be called to
+ *   collect the state of all buttons.  up_buttons() returns an 8-bit bit set
+ *   with each bit associated with a button.  See the BUTTON_*_BIT
+ *   definitions in board.h for the meaning of each bit.
+ *
+ *   up_irqbutton() may be called to register an interrupt handler that will
+ *   be called when a button is depressed or released.  The ID value is a
+ *   button enumeration value that uniquely identifies a button resource.
+ *   See the BUTTON_* definitions in board.h for the meaning of enumeration
+ *   value.  The previous interrupt handler address is returned (so that it
+ *   may restored, if so desired).
+ *
+ *   When an interrupt occurs, it is due to a change on the GPIO input pin
+ *   associated with the button.  In that case, all attached change
+ *   notification handlers will be called.  Each handler must maintain state
+ *   and determine if the unlying GPIO button input value changed.

+   *  When designing a self powered (as opposed to bus powered) USB peripheral

+   *  or D- pull up resistor unless Vbus is actively powered.  Therefore, the
+   *  firmware needs some means to detect when Vbus is being powered by the host.
+   *  A 5V tolerant I/O pin can be connected to Vbus (through a resistor), and
+   *  can be used to detect when Vbus is high (host actively powering), or low
+   *  (host is shut down or otherwise not supplying power).  The USB firmware
+   *  can then periodically poll this I/O pin to know when it is okay to turn on
+   *  the USB module/D+/D- pull up resistor.  When designing a purely bus powered
+   *  peripheral device, it is not possible to source current on D+ or D- when the

+Halfkey Bootloader
+^^^^^^^^^^^^^^^^^^
+
+o Download the Teensy application from http://pjrc.com/teensy/loader.html
+o Instructions are available for your OS at that places as well.
+
+Summary:
+
+1. Start Teensy
+2. Press button on the Teensy board
+3. Select a HEX file (File menu)
+4. Select "program" (Operations menu)
+5. Reboot (Operations menu).
+
+Serial Console
+^^^^^^^^^^^^^^
+
+  A serial console is supported on an external MAX232/MAX3232 Connected
+  on PD2 and PD3:
+
+  Port D, Bit 2: RXD1, Receive Data (Data input pin for the USART1). When
+    the USART1 receiver is enabled this pin is configured as an input
+    regardless of the value of DDD2. When the USART forces this pin to
+    be an input, the pull-up can still be controlled by the PORTD2 bit.
+  Port D, Bit 3: TXD1, Transmit Data (Data output pin for the USART1).
+    When the USART1 Transmitter is enabled, this pin is configured as
+    an output regardless of the value of DDD3.

+
+Toolchains
+^^^^^^^^^^
+
+There are several toolchain options.  However, testing has been performed
+using *only* the NuttX buildroot toolchain described below.  Therefore,
+the NuttX buildroot toolchain is the recommended choice:
+
+Buildroot:
+
+  There is a DIY buildroot version for the AVR boards here:
+  http://sourceforge.net/projects/nuttx/files/buildroot/.  See the
+  following section for details on building this toolchain.
+
+  It is assumed in some places that buildroot toolchain is available
+  at ../misc/buildroot/build_avr.  Edit the setenv.sh file if
+  this is not the case.
+
+  After configuring NuttX, make sure that CONFIG_AVR_BUILDROOT=y is set in your
+  .config file.
+
+WinAVR:
+
+  For Cygwin development environment on Windows machines, you can use
+  WinAVR: http://sourceforge.net/projects/winavr/files/
+
+  It is assumed in some places that WinAVR is installed at C:/WinAVR.  Edit the
+  setenv.sh file if this is not the case.
+
+  After configuring NuttX, make sure that CONFIG_AVR_WINAVR=y is set in your
+  .config file.
+
+  WARNING:  There is an incompatible version of cygwin.dll in the WinAVR/bin
+  directory!  Make sure that the path to the correct cygwin.dll file precedes
+  the path to the WinAVR binaries!
+
+Linux:
+
+  For Linux, there are widely available avr-gcc packages.  On Ubuntu, use:
+  sudo apt-get install gcc-avr gdb-avr avr-libc
+
+  After configuring NuttX, make sure that CONFIG_AVR_LINUXGCC=y is set in your
+  .config file.
+
+Windows Native Toolchains
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  The WinAVR toolchain is a Windows native toolchain. There are several
+  limitations to using a Windows native toolchain in a Cygwin environment. 
+  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath'
+     utility but you might easily find some new path problems.  If so, check
+     out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic
+     links are used in Nuttx (e.g., include/arch).  The make system works
+     around these  problems for the Windows tools by copying directories
+     instead of linking them.  But this can also cause some confusion for
+     you:  For example, you may edit a file in a "linked" directory and find
+     that your changes had no effect. That is because you are building the
+     copy of the file in the "fake" symbolic directory.  If you use a
+     Windows toolchain, you should get in the habit of making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This
+     is because the dependencies are generated using Windows pathes which do
+     not work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native
+     toolchains.  That support can be enabled by modifying your Make.defs
+     file as follows:
+
+    -  MKDEP = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are
+     not building on C:), then you may need to modify tools/mkdeps.sh
+
+  An additional issue with the WinAVR toolchain, in particular, is that it
+  contains an incompatible version of the Cygwin DLL in its bin/ directory.
+  You must take care that the correct Cygwin DLL is used.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  If NuttX buildroot toolchain source tarball cne can be downloaded from the
+  NuttX SourceForge download site (https://sourceforge.net/projects/nuttx/files/).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh Teensy++/<sub-dir>
+
+     NOTE: you also must copy avr-libc header files into the NuttX include
+     directory with command perhaps like:
+
+     cp -a /cygdrive/c/WinAVR/include/avr include/.
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/avr-defconfig-4.5.2 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you
+  are building a toolchain for Cygwin under Windows.
+
+avr-libc
+^^^^^^^^
+
+Header Files
+
+  In any case, header files from avr-libc are required:  http://www.nongnu.org/avr-libc/.
+  A snapshot of avr-lib is included in the WinAVR installation. For Linux
+  development platforms, avr-libc package is readily available (and would
+  be installed in the apt-get command shown above).  But if you are using
+  the NuttX buildroot configuration on Cygwin, then you will have to build
+  get avr-libc from binaries.
+
+Header File Installation
+
+  The NuttX build will required that the AVR header files be available via
+  the NuttX include directory.  This can be accomplished by either copying
+  the avr-libc header files into the NuttX include directory:
+
+  cp -a <avr-libc-path>/include/avr <nuttx-path>/include/.
+
+  Or simply using a symbolic link:
+
+  ln -s <avr-libc-path>/include/avr <nuttx-path>/include/.
+
+Build Notes:
+
+  It may not necessary to have a built version of avr-lib; only header files
+  are required.  Bu if you choose to use the optimized libraru functions of
+  the flowing point library, then you may have to build avr-lib from sources.
+  Below are instructions for building avr-lib from fresh sources:
+
+  1. Download the avr-libc package from: 
+
+     http://savannah.nongnu.org/projects/avr-libc/
+
+     I am using avr-lib-1.7.1.tar.bz2
+
+  2. Upack the tarball and cd into the 
+ 
+     tar jxf avr-lib-1.7.1.tar.bz2
+     cd avr-lib-1.7.1
+
+  3. Configure avr-lib.  Assuming that WinAVR is installed at the following
+     location:
+
+     export PATH=/cygdrive/c/WinAVR/bin:$PATH
+     ./configure --build=`./config.guess` --host=avr
+
+     This takes a *long* time.
+
+  4. Make avr-lib.
+
+     make
+
+     This also takes a long time because it generates variants for nearly
+     all AVR chips.
+
+  5. Install avr-lib.
+
+     make install
+
+Teensy++ Configuration Options
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+    CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+       be set to:
+
+       CONFIG_ARCH=avr
+
+    CONFIG_ARCH_family - For use in C code:
+
+       CONFIG_ARCH_AVR=y
+
+    CONFIG_ARCH_architecture - For use in C code:
+
+       CONFIG_ARCH_AT90USB=y
+
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+       CONFIG_ARCH_CHIP=at90usb
+
+    CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+       chip. 
+
+       CONFIG_ARCH_CHIP_AT90USB1286=y
+
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+
+       CONFIG_ARCH_BOARD=teensy
+
+    CONFIG_ARCH_BOARD_name - For use in C code
+
+       CONFIG_ARCH_BOARD_TEENSY=y
+
+    CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+       of delay loops
+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_DRAM_SIZE - Describes the installed DRAM.  One of:
+
+       CONFIG_DRAM_SIZE=(8*1024) - (8Kb)
+
+    CONFIG_DRAM_START - The start address of installed DRAM
+
+       CONFIG_DRAM_START=0x800100
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+       stack. If defined, this symbol is the size of the interrupt
+       stack in bytes.  If not defined, the user task stacks will be
+      used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.
+
+    Individual subsystems can be enabled:
+
+      CONFIG_AVR_INT0=n
+      CONFIG_AVR_INT1=n
+      CONFIG_AVR_INT2=n
+      CONFIG_AVR_INT3=n

+      CONFIG_AVR_TIMER0=n
+      CONFIG_AVR_TIMER1=n
+      CONFIG_AVR_TIMER2=n
+      CONFIG_AVR_TIMER3=n
+      CONFIG_AVR_SPI=n
+      CONFIG_AVR_USART1=y
+      CONFIG_AVR_ANACOMP=n
+      CONFIG_AVR_ADC=n
+      CONFIG_AVR_TWI=n
+ 
+  If the watchdog is enabled, this specifies the initial timeout.  Default
+  is maximum supported value.
+
+      CONFIG_WDTO_15MS
+      CONFIG_WDTO_30MS
+      CONFIG_WDTO_60MS
+      CONFIG_WDTO_120MS
+      CONFIG_WDTO_1250MS
+      CONFIG_WDTO_500MS
+      CONFIG_WDTO_1S
+      CONFIG_WDTO_2S
+      CONFIG_WDTO_4S
+      CONFIG_WDTO_8S
+
+  AT90USB specific device driver settings
+
+    CONFIG_USARTn_SERIAL_CONSOLE - selects the USARTn for the
+       console and ttys0 (default is no serial console).
+    CONFIG_USARTn_RXBUFSIZE - Characters are buffered as received.
+       This specific the size of the receive buffer
+    CONFIG_USARTn_TXBUFSIZE - Characters are buffered before
+       being sent.  This specific the size of the transmit buffer
+    CONFIG_USARTn_BAUD - The configure BAUD of the USART.  Must be
+    CONFIG_USARTn_BITS - The number of bits.  Must be either 7 or 8.
+    CONFIG_USARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
+    CONFIG_USARTn_2STOP - Two stop bits
+
+  AT90USB specific USB device configuration
+
+    CONFIG_USB_DISABLE_PADREGULATOR
+    CONFIG_USB_LOWSPEED
+    CONFIG_USB_NOISYVBUS
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each Teensy++ configuration is maintained in a sudirectory and can
+be selected as follow:
+
+    cd tools
+    ./configure.sh teensy/<subdir>
+    cd -
+    . ./setenv.sh
+
+NOTE: You must also copy avr-libc header files, perhaps like:
+
+     cp -a /cygdrive/c/WinAVR/include/avr include/.
+
+Where <subdir> is one of the following:
+
+  hello:
+    The simple apps/examples/hello "Hello, World!" example.
+
+  ostest:
+    This configuration directory, performs a simple OS test using
+    apps/examples/ostest. NOTE:  The OS test is quite large.  In order
+    to get it to fit within AVR memory constraints, it will probably be
+    necessary to disable some OS features.
+
+  usbstorage:
+    This configuration directory exercises the USB mass storage
+    class driver at apps/examples/usbstorage.  See apps/examples/README.txt
+    for more information.  NOTE:  THIS CONFIGURATION HAS NOT YET BEEN
+    DEBUGGED AND DOES NOT WORK!!!  ISSUES:  (1) THE SPI DRIVER IS UNTESTED,
+    (2) THE USB DRIVER IS UNTESTED, AND (3) THE RAM USAGE MIGHT BE EXCESSIVE.
+
+    Update 7/11:  (1) The SPI/SD driver has been verified, however, (2) I
+    believe that the current teensy/usbstorage configuration uses too
+    much SRAM for the system to behave sanely.  A lower memory footprint
+    version of the mass storage driver will be required before this can
+    be debugged

+ *
+ *   1. Provide logic in avr_sspinitialize() to configure SPI chip select pins.
+ *   2. Provide avr_spiselect() and avr_spistatus() functions in your board-specific
+ *      logic.  These functions will perform chip selection and status operations
+ *      in the way your board is configured.
+ *   3. Add a calls to at90usb_spiinitialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by up_spiinitialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling  mmcsd_spislotinitialize(),

+TWR-SER Serial Board Connection
+===============================
+
+The serial board connects into the tower and then maps to the tower pins to
+yet other functions (see TWR-SER.pdf).
+
+For the serial port, the following jumpers are required:
+
+  J15: 1-2 (default)
+  J17: 1-2 (default)
+  J18: 1-2 (default)
+  J19: 1-2 (default)
+
+The two connections map as follows:
+
+  A41 RXD0  - Not connected
+  A42 TXD0  - Not connected
+  A43 RXD1  - ELE_RXD (connects indirectory to DB-9 connector J8)
+  A44 TXD1  - ELE_TXD (connects indirectory to DB-9 connector J8)
+
+Finally, we can conclude that:
+
+  UART4 (PTE24/25) is not connected, and
+  UART3 (PTC16/17) is associated with the DB9 connector
+
+NOTE: UART5 is associated with OSJTAG bridge and may also be usable.
+
+LEDs
+====
+
+The TWR-K60N100 board has four LEDs labeled D2..D4 on the board.  Usage of
+these LEDs is defined in include/board.h and src/up_leds.c.  They are encoded
+as follows:
+
+	SYMBOL				Meaning					LED1*	LED2	LED3	LED4
+	-------------------	-----------------------	-------	-------	-------	------
+	LED_STARTED			NuttX has been started	ON		OFF		OFF		OFF
+	LED_HEAPALLOCATE	Heap has been allocated	OFF		ON		OFF		OFF
+	LED_IRQSENABLED		Interrupts enabled		ON		ON		OFF		OFF
+	LED_STACKCREATED	Idle stack created		OFF		OFF		ON		OFF
+	LED_INIRQ			In an interrupt**		ON		N/C		N/C		OFF
+	LED_SIGNAL			In a signal handler***  N/C		ON		N/C		OFF
+	LED_ASSERTION		An assertion failed		ON		ON		N/C		OFF
+	LED_PANIC			The system has crashed	N/C		N/C		N/C		ON
+    LED_IDLE            STM32 is is sleep mode  (Optional, not used)
+
+  * If LED1, LED2, LED3 are statically on, then NuttX probably failed to boot
+    and these LEDs will give you some indication of where the failure was
+ ** The normal state is LED3 ON and LED1 faintly glowing.  This faint glow
+    is because of timer interupts that result in the LED being illuminated
+    on a small proportion of the time.
+*** LED2 may also flicker normally if signals are processed.
+
+Development Environment
+=======================
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment.
+
+GNU Toolchain Options
+=====================
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the CodeSourcery Windows toolchain.  To
+  use the devkitARM or the NuttX GNU toolchain, you simply need to change the
+  the following configuration options to your .config (or defconfig) file:
+
+    CONFIG_KINETIS_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_KINETIS_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_KINETIS_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_KINETIS_BUILDROOT=y	    : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_KINETIS_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows) and devkitARM toolchains are
+  Windows native toolchains.  The CodeSourcey (for Linux) and NuttX buildroot
+  toolchains are Cygwin and/or Linux native toolchains. There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+====
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project.
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/k40,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/kinetis/k40_vectors.S.
+
+NuttX buildroot Toolchain
+=========================
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M4 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M4 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  NOTE:  The NuttX toolchain is an OABI toolchain (vs. the more common EABI)
+  and does not include optimizations for Cortex-M4 (ARMv7E-M).
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh twr-k60n512/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes

+TWR-K60N512-specific Configuration Options
+==========================================
+
+	CONFIG_ARCH - Identifies the arch/ subdirectory.  This sould
+	   be set to:
+
+	   CONFIG_ARCH=arm
+
+	CONFIG_ARCH_family - For use in C code:
+
+	   CONFIG_ARCH_ARM=y
+
+	CONFIG_ARCH_architecture - For use in C code:
+
+	   CONFIG_ARCH_CORTEXM4=y
+
+	CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+	   CONFIG_ARCH_CHIP=k40
+
+	CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+	   chip:
+
+	   CONFIG_ARCH_CHIP_MK60N512VMD100
+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=twr-k60n512 (for the TWR-K60N512 development board)
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+
+	   CONFIG_ARCH_BOARD_TWR_K60N512=y
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - Describes the installed DRAM (SRAM in this case):
+
+	   CONFIG_DRAM_SIZE=0x00010000 (64Kb)
+
+	CONFIG_DRAM_START - The start address of installed DRAM
+
+	   CONFIG_DRAM_START=0x20000000
+
+	CONFIG_ARCH_IRQPRIO - The Kinetis K60 supports interrupt prioritization
+
+	   CONFIG_ARCH_IRQPRIO=y
+
+	CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+	   have LEDs
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	    stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.

+Configurations
+==============
+
+Each TWR-K60N512 configuration is maintained in a sudirectory and
+can be selected as follow:
+
+	cd tools
+	./configure.sh twr-k60n512/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  ostest:
+  ------
+    This configuration directory, performs a simple OS test using
+    examples/ostest.  By default, this project assumes that you are
+    using the DFU bootloader.
+
+    CONFIG_KINETIS_BUILDROOT=y	  : NuttX buildroot under Linux or Cygwin
+
+  nsh:
+  ---
+    Configures the NuttShell (nsh) located at apps/examples/nsh.  The
+    Configuration enables both the serial and telnet NSH interfaces.
+    Support for the board's SPI-based MicroSD card is included
+    (but not passing tests as of this writing).
+
+	NOTE: An SDHC driver is underwork and can be enabled in the NSH
+    configuration for further testing be setting the following
+    configuration faluesas follows:
+
+      -CONFIG_KINETIS_SDHC=n
+      +CONFIG_KINETIS_SDHC=y         # Enable the SDHC driver
+
+      -CONFIG_GPIO_IRQ=n
+      +CONFIG_GPIO_IRQ=y             # Enable GPIO interrupts
+
+      -CONFIG_KINETIS_PORTEINTS=n
+      +CONFIG_KINETIS_PORTEINTS=y    # Enable PortE GPIO interrupts
+
+      -CONFIG_SCHED_WORKQUEUE=n
+      +CONFIG_SCHED_WORKQUEUE=y      # Enable the NuttX workqueue
+
+      -CONFIG_NSH_ARCHINIT=n

+ *   that, up_buttons() may be called to collect the current state of all
+ *   buttons or up_irqbutton() may be called to register button interrupt
+ *   handlers.
+ *
+ *   After up_buttoninit() has been called, up_buttons() may be called to
+ *   collect the state of all buttons.  up_buttons() returns an 8-bit bit set
+ *   with each bit associated with a button.  See the BUTTON_*_BIT and JOYSTICK_*_BIT
+ *   definitions in board.h for the meaning of each bit.
+ *
+ *   up_irqbutton() may be called to register an interrupt handler that will
+ *   be called when a button is depressed or released.  The ID value is a
+ *   button enumeration value that uniquely identifies a button resource. See the
+ *   BUTTON_* and JOYSTICK_* definitions in board.h for the meaning of enumeration
+ *   value.  The previous interrupt handler address is returned (so that it may
+ *   restored, if so desired).

+ *
+ *   1. Provide logic in kinetis_boardinitialize() to configure SPI chip select
+ *      pins.
+ *   2. Provide kinetis_spi1/2/3select() and kinetis_spi1/2/3status() functions in your
+ *      board-specific logic.  These functions will perform chip selection and

+ *   3. Add a calls to up_spiinitialize() in your low level application
+ *      initialization logic

+====================
+
+This README file discusses the port of NuttX to the Sparkfun UBW32 board.
+This port uses the original v2.5 board which is based on the MicroChip
+PIC32MX460F512L.  See http://www.sparkfun.com/products/8971.  This older
+version has been replaced with this board http://www.sparkfun.com/products/9713.
+See also http://www.schmalzhaus.com/UBW32/.

+PIC32MX460F512L Pin Out
+=======================
+
+  PIC32MX460F512L 100-Pin TQFP (USB) Pin Out.  The mapping to the pins on
+  the PCL Logic board are very simple, each pin is brought out to a connector
+  label with the PIC32MX460F512L pin number.
+
+  On board logic only manages power, crystal, and USB signals.

+MAX3232 Connection
+==================
+
+  I use a tiny, MAX3232 board that I got from the eBay made by NKC
+  Electronics (http://www.nkcelectronics.com/).  As of this writing, it
+  is also available here: http://www.nkcelectronics.com/rs232-to-ttl-3v--55v-convert232356.html
+
+  CTS -- Not connected
+  RTS -- Not connected
+  TX  -- J4 pin 31: U1TX/RF8
+  RX  -- J4 pin 30: U1RX/RF2
+  GND -- J4 pin 40: GND
+  Vcc -- J4 pin 39: 5V
+ 
+Toolchains
+==========
+
+  MPLAB/C32
+  ---------
+
+  I am using the free, "Lite" version of the PIC32MX toolchain available
+  for download from the microchip.com web site.  I am using the Windows
+  version.  The MicroChip toolchain is the only toolchain currently
+  supported in these configurations, but it should be a simple matter to
+  adapt to other toolchains by modifying the Make.defs file include in
+  each configuration.
+
+  C32 Toolchain Options:
+
+    CONFIG_PIC32MX_MICROCHIPW      - MicroChip full toolchain for Windows
+    CONFIG_PIC32MX_MICROCHIPL      - MicroChip full toolchain for Linux
+    CONFIG_PIC32MX_MICROCHIPW_LITE - MicroChip "Lite" toolchain for Windows
+    CONFIG_PIC32MX_MICROCHIPL_LITE - MicroChip "Lite" toolchain for Linux
+
+  NOTE:  The "Lite" versions of the toolchain does not support C++.  Also
+  certain optimization levels are not supported by the "Lite" toolchain.
+
+  MicrochipOpen
+  -------------
+
+  An alternative, build-it-yourself toolchain is available here:
+  http://sourceforge.net/projects/microchipopen/ .  These tools were
+  last updated circa 2010.  NOTE:  C++ support still not available
+  in this toolchain.
+
+  Building MicrochipOpen (on Linux)
+
+  1) Get the build script from this location:
+
+      http://microchipopen.svn.sourceforge.net/viewvc/microchipopen/ccompiler4pic32/buildscripts/trunk/
+
+  2) Build the code using the build script, for example:
+
+      ./build.sh -b v105_freeze
+
+     This will check out the selected branch and build the tools.
+
+  3) Binaries will then be available in a subdirectory with a name something like
+     pic32-v105-freeze-20120622/install-image/bin (depending on the current data
+     and the branch that you selected.
+
+     Note that the tools will have the prefix, mypic32- so, for example, the
+     compiler will be called mypic32-gcc.
+
+  Pinguino mips-elf Toolchain
+  ---------------------------
+
+  Another option is the mips-elf toolchain used with the Pinguino project.  This
+  is a relatively current mips-elf GCC and should provide free C++ support as
+  well. This toolchain can be downloded from the Pinguino website:
+  http://wiki.pinguino.cc/index.php/Main_Page#Download . There is some general
+  information about using the Pinguino mips-elf toolchain in this thread:

+
+  MPLAB/C32 vs MPLABX/X32
+  -----------------------
+
+  It appears that Microchip is phasing out the MPLAB/C32 toolchain and replacing
+  it with MPLABX and XC32.  At present, the XC32 toolchain is *not* compatible
+  with the NuttX build scripts.  Here are some of the issues that I see when trying
+  to build with XC32:
+
+  1) Make.def changes:  You have to change the tool prefix:
+
+     -CROSSDEV=pic32-
+     +CROSSDEV=xc32-
+
+  2) debug.ld/release.ld:  The like expect some things that are not present in
+     the current linker scripts (or are expected with different names).  Here
+     are some partial fixes:
+
+     Rename:  kseg0_progmem to kseg0_program_mem
+     Rename:  kseg1_datamem to kseg1_data_mem
+
+  Even then, there are more warnings from the linker and some undefined symbols
+  for non-NuttX code that resides in the unused Microchip libraries.  See this
+  email thread at http://tech.groups.yahoo.com/group/nuttx/message/1458 for more
+  information.  You will have to solve at least this undefined symbol problem if
+  you want to used the XC32 toolchain.
+
+  Windows Native Toolchains
+  -------------------------
+  
+  NOTE:  There are several limitations to using a Windows based toolchain in a
+  Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+Loading NuttX with PICkit2
+==========================
+
+  NOTE:  You need a PICKit3 if you plan to use the MPLAB debugger!  The PICKit2
+  can, however, still be used to load programs.  Instructions for the PICKit3
+  are similar.
+
+  Intel Hex Forma Files:
+  ----------------------
+
+    When NuttX is built it will produce two files in the top-level NuttX
+    directory:
+
+    1) nuttx - This is an ELF file, and
+    2) nuttx.hex - This is an Intel Hex format file.  This is controlled by
+       the setting CONFIG_INTELHEX_BINARY in the .config file.
+
+    The PICkit tool wants an Intel Hex format file to burn into FLASH. However,
+    there is a problem with the generated nutt.hex: The tool expects the nuttx.hex
+    file to contain physical addresses.  But the nuttx.hex file generated from the
+    top-level make will have address in the KSEG0 and KSEG1 regions.
+
+  tools/pic32mx/mkpichex:
+  ----------------------
+
+    There is a simple tool in the NuttX tools/pic32mx directory that can be
+    used to solve both issues with the nuttx.hex file.  But, first, you must
+    build the tool:
+
+      cd tools/pic32mx
+      make
+
+    Now you will have an excecutable file call mkpichex (or mkpichex.exe on
+    Cygwin).  This program will take the nutt.hex file as an input, it will
+    convert all of the KSEG0 and KSEG1 addresses to physical address, and
+    it will write the modified file, replacing the original nuttx.hex.
+
+    To use this file, you need to do the following things:
+
+      . ./setenv.sh    # Source setenv.sh.  Among other this, this script
+                       # will add the NuttX tools/pic32mx directory to your
+                       # PATH variable
+      make             # Build nuttx and nuttx.hex
+      mkpichex $PWD    # Convert addresses in nuttx.hex.  $PWD is the path
+                       # to the top-level build directory.  It is the only
+                       # required input to mkpichex.

+PIC32MX Configuration Options
+=============================
+
+  General Architecture Settings:
+
+    CONFIG_ARCH - Identifies the arch/ subdirectory.  This should
+     be set to:
+
+       CONFIG_ARCH=mips
+
+    CONFIG_ARCH_family - For use in C code:
+
+       CONFIG_ARCH_MIPS=y
+
+    CONFIG_ARCH_architecture - For use in C code:
+
+       CONFIG_ARCH_MIPS32=y
+
+    CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+       CONFIG_ARCH_CHIP=pic32mx
+
+    CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+       chip:
+
+       CONFIG_ARCH_CHIP_PIC32MX460F512L=y
+
+    CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+       hence, the board that supports the particular chip or SoC.
+
+       CONFIG_ARCH_BOARD=ubw32
+
+    CONFIG_ARCH_BOARD_name - For use in C code
+
+       CONFIG_ARCH_BOARD_UBW32=y
+
+    CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+       of delay loops
+
+    CONFIG_ENDIAN_BIG - define if big endian (default is little
+       endian)
+
+    CONFIG_DRAM_SIZE - Describes the installed DRAM (CPU SRAM in this case):
+
+       CONFIG_DRAM_SIZE=(32*1024) (32Kb)
+
+       There is an additional 32Kb of SRAM in AHB SRAM banks 0 and 1.
+
+    CONFIG_DRAM_START - The start address of installed DRAM
+
+       CONFIG_DRAM_START=0xa0000000
+
+    CONFIG_ARCH_IRQPRIO - The PIC32MXx supports interrupt prioritization
+
+       CONFIG_ARCH_IRQPRIO=y
+
+    CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+       have LEDs
+
+    CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+       stack. If defined, this symbol is the size of the interrupt
+       stack in bytes.  If not defined, the user task stacks will be
+       used during interrupt handling.
+
+    CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+    CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+    CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+       cause a 100 second delay during boot-up.  This 100 second delay
+       serves no purpose other than it allows you to calibratre
+       CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+       the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+       the delay actually is 100 seconds.

+    USB Configuations.
+    -----------------
+    Several USB device configurations can be enabled and included
+    as NSH built-in built in functions.
+
+    All USB device configurations require the following basic setup in
+    your NuttX configuration file to enable USB device support:
+
+      CONFIG_USBDEV=y         : Enable basic USB device support
+      CONFIG_PIC32MX_USBDEV=y : Enable PIC32 USB device support
+
+    examples/usbterm - This option can be enabled by uncommenting
+    the following line in the appconfig file:
+
+      CONFIGURED_APPS += examples/usbterm
+
+    And by enabling one of the USB serial devices:
+
+      CONFIG_PL2303=y         : Enable the Prolifics PL2303 emulation
+      CONFIG_CDCACM=y         : or the CDC/ACM serial driver (not both)
+
+    examples/cdcacm -  The examples/cdcacm program can be included as an
+    function by uncommenting the following line in the appconfig file:
+
+      CONFIGURED_APPS += examples/cdcacm
+
+    and defining the following in your .config file:
+
+      CONFIG_CDCACM=y         : Enable the CDCACM device

+ *   buttons or up_irqbutton() may be called to register button interrupt
+ *   handlers.
+ *
+ *   After up_buttoninit() has been called, up_buttons() may be called to
+ *   collect the state of all buttons.  up_buttons() returns an 8-bit bit set
+ *   with each bit associated with a button.  See the BUTTON_*_BIT
+ *   definitions in board.h for the meaning of each bit.
+ *
+ *   up_irqbutton() may be called to register an interrupt handler that will
+ *   be called when a button is depressed or released.  The ID value is a
+ *   button enumeration value that uniquely identifies a button resource.
+ *   See the BUTTON_* definitions in board.h for the meaning of enumeration
+ *   value.  The previous interrupt handler address is returned (so that it
+ *   may restored, if so desired).
+ *
+ *   When an interrupt occurs, it is due to a change on the GPIO input pin
+ *   associated with the button.  In that case, all attached change
+ *   notification handlers will be called.  Each handler must maintain state
+ *   and determine if the unlying GPIO button input value changed.

+Status
+^^^^^^
+
+*** UNSTABLE ***
+The port is basically complete and many examples run correctly.  However, there
+are remaining instabilities that make the port un-usable.  The nature of these
+is not understood; the behavior is that certain SH-1 instructions stop working
+as advertised.  This could be a silicon problem, some pipeline issue that is not
+handled properly by the gcc 3.4.5 toolchain (which has very limit SH-1 support
+to begin with), or perhaps with the CMON debugger.  At any rate, I have exhausted
+all of the energy that I am willing to put into this cool old processor for the
+time being.
+
+Toolchain
+^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the SH toolchain (if
+  different from the default).
+
+  If you have no SH toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+
+  1. You must have already configured Nuttx in <some-dir>nuttx.
+
+     cd tools
+     ./configure.sh us7032evb1/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/sh-defconfig .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h so that the PATH variable includes the path to the
+     newly built binaries.
+
+shterm
+^^^^^^
+
+  The USB7032EVB1 supports CMON in PROM.  CMON requires special
+  serial interactions in order to upload and download program files.
+  Therefore, a standard terminal emulation program (such as minicom)
+  cannot be used.
+
+  The shterm subdirectory contains a small terminal emulation
+  program that supports these special interactions for file transfers.
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each SH-1 configuration is maintained in a sudirectory and
+can be selected as follow:
+
+	cd tools
+	./configure.sh us7032evb1/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+ostest
+^^^^^^as advertised.  This could be a silicon problem, some pipeline issue that is not handled properly by the gcc 3.4.5 tool
+
+This configuration directory, performs a simple OS test using
+examples/ostest.
+
+nsh
+^^^
+
+Configures the NuttShell (nsh) located at examples/nsh.  The
+Configuration enables only the serial NSH interfaces.
+
+NOTE:  At present, the NSH example does not run.  See the "Status"
+discussion above for a full explanation.
+
+Configuration Options
+^^^^^^^^^^^^^^^^^^^^^
+
+In additional to the common configuration options listed in the
+file configs/README.txt, there are other configuration options
+specific to the SH-1
+
+Architecture selection
+
+  CONFIG_ARCH - identifies the arch subdirectory and, hence, the
+    processor architecture.  This should be sh (for arch/sh)
+  CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory.
+    This should be sh1 (for arch/sh/src/sh1 and arch/sh/include/sh1)
+  CONFIG_ARCH_SH1 and CONFIG_ARCH_CHIP_SH7032 - for use in C code.  These
+    identify the particular chip or SoC that the architecture is
+    implemented in.
+  CONFIG_ARCH_BOARD - identifies the configs subdirectory and, hence,
+    the board that supports the particular chip or SoC.  This
+    should be us7032evb1 for (configs/us7032evb1).
+  CONFIG_ARCH_BOARD_US7032EVB1 - for use in C code
+  CONFIG_ENDIAN_BIG - the SH-1 usually runs big-endian
+  CONFIG_ARCH_NOINTC - define if the architecture does not
+    support an interrupt controller or otherwise cannot support
+    APIs like up_enable_irq() and up_disable_irq().  Should be
+    defined.
+  CONFIG_ARCH_IRQPRIO
+    Define if the architecture suports prioritizaton of interrupts
+    and the up_prioritize_irq() API.  Should be defined.
+  CONFIG_BOARD_LOOPSPERMSEC - for delay loops
+  CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to SH1_LCEVB1
+  CONFIG_DRAM_SIZE - Describes the internal DRAM.
+  CONFIG_DRAM_START - The start address of internal DRAM
+  CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+    stack. If defined, this symbol is the size of the interrupt
+    stack in bytes.  If not defined, the user task stacks will be
+    used during interrupt handling.
+  CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+  CONFIG_SH1_DMAC0, CONFIG_SH1_DMAC1, CONFIG_SH1_DMAC2, CONFIG_SH1_DMAC3,
+  CONFIG_SH1_ITU1, CONFIG_SH1_ITU2, CONFIG_SH1_ITU3, CONFIG_SH1_ITU4,
+  CONFIG_SH1_SCI0, CONFIG_SH1_SCI1, CONFIG_SH1_PCU, CONFIG_SH1_AD,
+  CONFIG_SH1_WDT, CONFIG_SH1_CMI - Each unused chip block should b
+    disabled to save space
+
+SH1 specific device driver settings
+
+  CONFIG_SCIn_SERIAL_CONSOLE - selects the SCIn for the
+    console and ttys0 (default is the UART0).
+  CONFIG_SCIn_RXBUFSIZE - Characters are buffered as received.
+    This specific the size of the receive buffer
+  CONFIG_SCIn_TXBUFSIZE - Characters are buffered before
+    being sent.  This specific the size of the transmit buffer
+  CONFIG_SCIn_BAUD - The configure BAUD of the UART.  Must be
+  CONFIG_SCIn_BITS - The number of bits.  Must be either 7 or 8.
+  CONFIG_SCIn_PARTIY - 0=no parity, 1=odd parity, 2=even parity, 3=mark 1, 4=space 0
+  CONFIG_SCIn_2STOP - Two stop bits

+README
+^^^^^^
+
+This README discusses issues unique to NuttX configurations for the
+ISOTEL NetClamps VSN V1.2 ready2go sensor network platform.
+More information can be found at http://www.netclamps.com
+
+Contents
+^^^^^^^^
+

+  - GNU Toolchain Options
+  - IDEs
+  - NuttX buildroot Toolchain
+  - DFU
+  - LEDs
+  - VSN-specific Configuration Options
+  - Configurations
+
+Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^
+
+  Either Linux or Cygwin on Windows can be used for the development environment.
+  The source has been built only using the GNU toolchain (see below).  Other
+  toolchains will likely cause problems. Testing was performed using the Cygwin
+  environment because the Raisonance R-Link emulatator and some RIDE7 development tools
+  were used and those tools works only under Windows.
+
+GNU Toolchain Options
+^^^^^^^^^^^^^^^^^^^^^
+
+  The NuttX make system has been modified to support the following different
+  toolchain options.
+
+  1. The CodeSourcery GNU toolchain,
+  2. The devkitARM GNU toolchain,
+  3. Raisonance GNU toolchain, or
+  4. The NuttX buildroot Toolchain (see below).
+
+  All testing has been conducted using the NuttX buildroot toolchain.  However,
+  the make system is setup to default to use the devkitARM toolchain.  To use
+  the CodeSourcery, devkitARM or Raisonance GNU toolchain, you simply need to
+  add one of the following configuration options to your .config (or defconfig)
+  file:
+
+    CONFIG_STM32_CODESOURCERYW=y  : CodeSourcery under Windows
+    CONFIG_STM32_CODESOURCERYL=y  : CodeSourcery under Linux
+    CONFIG_STM32_DEVKITARM=y      : devkitARM under Windows
+    CONFIG_STM32_RAISONANCE=y     : Raisonance RIDE7 under Windows
+    CONFIG_STM32_BUILDROOT=y	  : NuttX buildroot under Linux or Cygwin (default)
+
+  If you are not using CONFIG_STM32_BUILDROOT, then you may also have to modify
+  the PATH in the setenv.h file if your make cannot find the tools.
+
+  NOTE: the CodeSourcery (for Windows), devkitARM, and Raisonance toolchains are
+  Windows native toolchains.  The CodeSourcey (for Linux) and NuttX buildroot
+  toolchains are Cygwin and/or Linux native toolchains. There are several limitations
+  to using a Windows based toolchain in a Cygwin environment.  The three biggest are:
+
+  1. The Windows toolchain cannot follow Cygwin paths.  Path conversions are
+     performed automatically in the Cygwin makefiles using the 'cygpath' utility
+     but you might easily find some new path problems.  If so, check out 'cygpath -w'
+
+  2. Windows toolchains cannot follow Cygwin symbolic links.  Many symbolic links
+     are used in Nuttx (e.g., include/arch).  The make system works around these
+     problems for the Windows tools by copying directories instead of linking them.
+     But this can also cause some confusion for you:  For example, you may edit
+     a file in a "linked" directory and find that your changes had no effect.
+     That is because you are building the copy of the file in the "fake" symbolic
+     directory.  If you use a Windows toolchain, you should get in the habit of
+     making like this:
+
+       make clean_context all
+
+     An alias in your .bashrc file might make that less painful.
+
+  3. Dependencies are not made when using Windows versions of the GCC.  This is
+     because the dependencies are generated using Windows pathes which do not
+     work with the Cygwin make.
+
+     Support has been added for making dependencies with the windows-native toolchains.
+     That support can be enabled by modifying your Make.defs file as follows:
+
+    -  MKDEP                = $(TOPDIR)/tools/mknulldeps.sh
+    +  MKDEP                = $(TOPDIR)/tools/mkdeps.sh --winpaths "$(TOPDIR)"
+
+     If you have problems with the dependency build (for example, if you are not
+     building on C:), then you may need to modify tools/mkdeps.sh
+
+  NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
+  level of -Os (See Make.defs).  It will work with -O0, -O1, or -O2, but not with
+  -Os.
+
+  NOTE 2: The devkitARM toolchain includes a version of MSYS make.  Make sure that
+  the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
+  path or will get the wrong version of make.
+
+IDEs
+^^^^
+
+  NuttX is built using command-line make.  It can be used with an IDE, but some
+  effort will be required to create the project (There is a simple RIDE project
+  in the RIDE subdirectory).
+  
+  Makefile Build
+  --------------
+  Under Eclipse, it is pretty easy to set up an "empty makefile project" and
+  simply use the NuttX makefile to build the system.  That is almost for free
+  under Linux.  Under Windows, you will need to set up the "Cygwin GCC" empty
+  makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
+  there is a lot of help on the internet).
+
+  Native Build
+  ------------
+  Here are a few tips before you start that effort:
+
+  1) Select the toolchain that you will be using in your .config file
+  2) Start the NuttX build at least one time from the Cygwin command line
+     before trying to create your project.  This is necessary to create
+     certain auto-generated files and directories that will be needed.
+  3) Set up include pathes:  You will need include/, arch/arm/src/stm32,
+     arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
+  4) All assembly files need to have the definition option -D __ASSEMBLY__
+     on the command line.
+
+  Startup files will probably cause you some headaches.  The NuttX startup file
+  is arch/arm/src/stm32/stm32_vectors.S.  With RIDE, I have to build NuttX
+  one time from the Cygwin command line in order to obtain the pre-built
+  startup object needed by RIDE.
+
+NuttX buildroot Toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+  A GNU GCC-based toolchain is assumed.  The files */setenv.sh should
+  be modified to point to the correct path to the Cortex-M3 GCC toolchain (if
+  different from the default in your PATH variable).
+
+  If you have no Cortex-M3 toolchain, one can be downloaded from the NuttX
+  SourceForge download site (https://sourceforge.net/project/showfiles.php?group_id=189573).
+  This GNU toolchain builds and executes in the Linux or Cygwin environment.
+
+  1. You must have already configured Nuttx in <some-dir>/nuttx.
+
+     cd tools
+     ./configure.sh vsn/<sub-dir>
+
+  2. Download the latest buildroot package into <some-dir>
+
+  3. unpack the buildroot tarball.  The resulting directory may
+     have versioning information on it like buildroot-x.y.z.  If so,
+     rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
+
+  4. cd <some-dir>/buildroot
+
+  5. cp configs/cortexm3-defconfig-4.3.3 .config
+
+  6. make oldconfig
+
+  7. make
+
+  8. Edit setenv.h, if necessary, so that the PATH variable includes
+     the path to the newly built binaries.
+
+  See the file configs/README.txt in the buildroot source tree.  That has more
+  detailed PLUS some special instructions that you will need to follow if you are
+  building a Cortex-M3 toolchain for Cygwin under Windows.
+
+
+VSN-specific Configuration Options

+
+	CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+	   hence, the board that supports the particular chip or SoC.
+
+	   CONFIG_ARCH_BOARD=vsn (for the VSN development board)
+
+	CONFIG_ARCH_BOARD_name - For use in C code
+	
+	   CONFIG_ARCH_BOARD_VSN=y
+
+	CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+	   of delay loops
+
+	CONFIG_ENDIAN_BIG - define if big endian (default is little
+	   endian)
+
+	CONFIG_DRAM_SIZE - Describes the installed DRAM (SRAM in this case):
+
+	   CONFIG_DRAM_SIZE=0x00010000 (64Kb)
+
+	CONFIG_DRAM_START - The start address of installed DRAM
+
+	   CONFIG_DRAM_START=0x20000000
+
+	CONFIG_ARCH_IRQPRIO - The STM32F103Z supports interrupt prioritization
+
+	   CONFIG_ARCH_IRQPRIO=y
+
+	CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+	   stack. If defined, this symbol is the size of the interrupt
+	    stack in bytes.  If not defined, the user task stacks will be
+	  used during interrupt handling.
+
+	CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+	CONFIG_ARCH_LEDS -  Use LEDs to show state. Unique to board architecture.
+
+	CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+	   cause a 100 second delay during boot-up.  This 100 second delay
+	   serves no purpose other than it allows you to calibratre
+	   CONFIG_ARCH_LOOPSPERMSEC.  You simply use a stop watch to measure
+	   the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+	   the delay actually is 100 seconds.
+
+
+Configurations
+^^^^^^^^^^^^^^
+
+Each VSN configuration is maintained in a sudirectory and
+can be selected as follow:
+
+	cd tools
+	./configure.sh vsn/<subdir>
+	cd -
+	. ./setenv.sh
+
+Where <subdir> is one of the following:
+
+  nsh:
+    Configures the NuttShell (nsh) located at examples/nsh.  The
+    Configuration enables both the serial and telnetd NSH interfaces.
+
+The default configuration sets up a console on front-panel RS-232 
+interface, sets up device driver of all supported equipment and 
+links in VSN default applications.

+VSN Board Support Package, for the NuttX, Uros Platise <uros.platise@isotel.eu>
+===============================================================================
+http://www.netClamps.com
+
+The directory contains start-up and board level functions. 
+Execution starts in the following order:
+
+ - sysclock, immediately after reset stm32_rcc calls external
+   clock configuration when
+     CONFIG_ARCH_BOARD_STM32_CUSTOM_CLOCKCONFIG=y
+   is set. It must be set for the VSN board.
+   
+ - boot, performs initial chip and board initialization
+ - sched/os_bringup.c then calls either user_start or exec_namedapp()
+   with application as set in the .config
+
+
+Naming throughout the code
+==========================
+
+ - _init(): used to be called once only, after powerup, to perform board
+   initialization
+ - _start() or called via FS _open(): starts peripheral power, puts it 
+   into operation
+ - _stop() or called via FS _close(): opposite to _start()
+ 
+
+System notifications (a sort of run-levels)
+===========================================
+
+On the VSN, NSH represents the core application as it supports scripts
+easily adaptable for any custom application configuration. NSH is 
+invoked as follows (argument runs a script from the /etc/init.d directory):
+
+ - nsh init: on system powerup called by the NuttX APP_START
+
+TODOs: 
+ 
+ - nsh xpowerup: run on external power used to:
+   - try to setup an USB serial connection
+   - configure SLIP mode, internet
+   - start other internet services, such as telnetd, ftpd, httpd
+   
+ - nsh xpowerdown: run whenever USB recevied suspend signal or
+   external power has been removed.
+   - used to stop internet services
+   
+ - nsh batdown: whenever battery is completely discharged
+
+   
+Compile notes
+===============================
+
+To link-in the sif_main() utility do, in this folder:
+ - make context TOPDIR=<path to nuttx top dir>
+ 
+This will result in registering the application into the namedapp.

+ *      board-specific logic.  These functions will perform chip selection and
+ *      status operations using GPIOs in the way your board is configured.
+ *   3. Add a calls to up_spiinitialize() in your low level application
+ *      initialization logic
+ *   4. The handle returned by up_spiinitialize() may then be used to bind the
+ *      SPI driver to higher level logic (e.g., calling

+xtrs README
+^^^^^^^^^^^^^
+
+Current status
+^^^^^^^^^^^^^^
+
+The xtrs port is not operational yet; some work still needs to be done.
+
+Contents
+^^^^^^^^
+
+  o Getting a TRS80 emulator and DOS disks
+  o Loading an executable into xtrs
+  o Configuring NuttX
+  o Building the SDCC toolchain
+  o SDCC Update
+  o Newer SDCC Versions
+
+Getting a TRS80 emulator and DOS disks
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This port uses a vintage computer based on the Z80, the TRS80.
+There's a main page describing the different models of TRS80.
+See: http://www.trs-80.com
+
+An emulator for this computer is available to run TRS80 programs on a 
+linux platform (http://www.tim-mann.org/xtrs.html).
+
+Other emulators are available for other platforms. 
+See http://www.trs-80.com, click on the link Emulators.
+
+TRSDOS, LDOS and other softwares are available at:
+http://discover-net.net/~dmkeil/trs80/software/trs-dos.htm
+
+Or you can get TRSDOS 1.3 and 6.1 from this site; it's included with the emulator.
+http://discover-net.net/~dmkeil/trs80/model4.htm
+
+The SDCC toolchain is available from http://sdcc.sourceforge.net/.  All
+testing has been performed using version 2.7.0 of the SDCC toolchain.
+
+Loading an executable into xtrs
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+At http://www.trs-80.com click on the link: Getting a Software Onto an Emulator.
+
+Configuring NuttX
+^^^^^^^^^^^^^^^^^
+
+  ostest
+    This configuration performs a simple, minimal OS test using
+    examples/ostest.  This can be configurated as follows:
+
+       cd tools
+       ./configure.sh xtrs/ostest
+       cd -
+       . ./setenv.sh
+
+  nsh
+    This configuration file builds NSH (examples/nsh).  This
+    configuration is not functional due to issues with use of the
+    simulated serial driver (see the TODO list).
+
+    This configuration can be selected by:
+
+       cd tools
+       ./configure.sh xtrs/nsh
+       cd -
+       . ./setenv.sh
+
+ pashello
+    Configures to use examples/pashello for execution from FLASH
+    See examples/README.txt for information about pashello.
+
+    This configuration is not usable because the resulting binary
+    is too large for the z80 address space.
+
+    This configuration can be selected by:
+
+       cd tools
+       ./configure.sh xtrs/pashello
+       cd -
+       . ./setenv.sh
+
+Building the SDCC toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The SDCC toolchain is built with the standard configure/make/make install
+sequence.  However, some special actions are required to generate libraries
+compatible with this build.  First start with the usual steps
+
+  download
+  unpack
+  cd sdcc
+  ./configure
+
+But before making, we need to apply a patch to the SDCC 2.6.0 source
+so that the z80 assembler can handle long symbol names
+
+  Apply sdcc-2.6.0-asz80-symlen.patch
+  cd sdcc/device/lib
+
+Then make the SDCC binaries
+
+  cd sdcc
+  make
+
+and install SDCC:
+
+  sudo make install
+
+SDCC Update
+^^^^^^^^^^^
+
+I have had some problems building sdcc-2.6.0 on my current UBUNTU
+release (9.10).  I had other problems building sdcc-2.9.0 on UBUNTU 9.10.
+I suspect that the newer gcc toolchains are causing problems for these
+older SDCC releases.
+
+A 20091106 snapshot did build with no major problems on UBUNTU 9.10, but
+has some compatibilty problems with the older SDCC compiler.  For one, you
+will need to change the Z80 assember name and options in the Make.defs
+files as follows:
+
+-AS         = as-z80
++AS         = sdasz80
+ 
+-    @$(AS) $(ASFLAGS) $2 $1
++    $(AS) $(ASFLAGS) $1
+
+For another, I had other problems building with that 20091106 that look
+like compiler bugs.  If you are using UBUNTU 9.10, you may have to either
+(1) downgrade your GCC compiler to a version 3.x compiler and use one of
+the older stable releases, or (2) wait for the next stable SDCC release
+after 2.9.0.
+
+See below:  If you wish to continue using the older SDCC toolchain, you
+must now also add CONFIG_SDCC_OLD=y to your configuration file.
+
+Newer SDCC Versions
+^^^^^^^^^^^^^^^^^^^
+
+This is the text of bug 3468951 reported on the SourceForge website:
+
+"Some obsolete stuff in z80sim port," (submitted by Philipp Klaus Krause):
+
+  The simz80 port needs a few updates to work well with current sdcc versions,
+  and has some unecessary stuff:
+
+  * The linker name for Make.defs should be sdldz80
+  * The assembler name for Make.defs should be sdasz80
+  * _asm and _endasm in z80_io.c and z80_irq.c should be replaced by __asm
+    and __endasm
+  * The --stack-auto --int-long-reent --float-reent options or Make.defs should
+     be removed, as they have no effect on sdcc's z80 port
+  * The current assembler AFAIK can handle long symbol names, so the
+    sdcc-2.6.0-asz80-symlen.patch is unnecessary, and it and the corresponding
+    section from the README can be removed.
+
+These changes *have* been incorporated but only partially verified.  In order
+to get a successful compilation, I had to copy stdarg.h out of the SDCC source
+(at sdcc/device/include/stdarg.h) to include/nuttx/stdarg.h.
+
+There are also some library related issues when you get to the final build
+that I have not looked into yet.
+
+If you want to back out these change and continue to use the older toolchain
+in your build, simpy define the following in your configuration file:
+

+README.txt
+^^^^^^^^^^
+
+This is the README file for the NuttX port to the ZiLog ZNEO MCU.
+
+ZDS-II Compiler Versions
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+4.10.2
+  The ZDS-II version 4.10.2 will not compile NuttX.  It reports "internal
+  errors" on some of the files.  Upgrades to ZDS-II are available for
+  download from the Zilog website: http://www.zilog.com/software/zds2.asp
+
+4.11.0
+  NuttX compiles correctly with the newer 4.11.0 version of the ZDS-II
+  toolchain.  However, I have found a few issues:
+
+  - The code will not run without the -reduceopt option.  There is,
+    apparently, some optimization related issue.  This issue has not
+    been analyzed as of this writing.
+
+  - Not all NuttX logic will not run with the -regvars option.  There is
+    at least one failure that has been reported to ZiLOG as incident 81400.
+
+  - The Pascal add-on interpreter includes a large switch statement and
+    exposes another compiler problem.  This is reported as incident 81459.
+
+4.11.1
+  As of this writing (30 September 2010), the latest release of ZDS-II for the
+  ZNEO is 4.11.1.  It is unknown if this release includes fixes for incidents
+  81400 and 81459 or not.  It is unknown if the code will run without -reduceopt
+  either. (Basically, it compiles with 4.11.1, but is untested with that version).
+
+If you use any version of ZDS-II other than 4.11.1 or if you install ZDS-II
+at any location other than the default location, you will have to modify
+two files:  (1) configs/z16f2800100zcog/*/setenv.sh and (2)
+configs/z16f2800100zcog/*/Make.defs.  Simply edit these two files, changing
+4.11.1 to whatever.
+
+Issues
+^^^^^^
+
+There are several, important open issues with the ZNEO port (8 as of this writing).
+See the TODO file in the top-level NuttX directory.  One of these should be
+mentioned here because it causes a failure to compile Nuttx:
+
+  Description: The file drivers/mmcsd/mmcsd_sdio.c generates an internal compiler
+               error like:
+ 
+               mmcsd\mmcsd_sdio.c
+               Internal Error(0503) On line 2524 of "MMCSD\MMCSD_SDIO.C"
+                   File <c3>, Args(562,46)
+
+  Status:     Open.  Recommended workaround: remove mmcsd_sdio.c from
+              drivers/mmcsd/Make.defs.  There is no SDIO support for the Z16 anyway
+  Priority:   Low
+
+This is bug in ZDS-II.  It was discovered in version 4.11.0 and still exists
+in version 4.11.1.
+
+Configuration Subdirectories
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- source/ and include/
+    These directories contain common logic for all z16f2800100zcog
+    configurations.
+
+Variations on the basic z8f162800100zcog configuration are maintained
+in subdirectories.  To configure any specific configuration, do the
+following steps:
+
+   cd <nuttx-top-directory>/tools
+   ./configure.sh z16f2800100zcog/<sub-directory>
+   cd <nuttx-top-directory>
+   make
+
+Where <sub-directory> is the specific board configuration that you
+wish to build.  The following board-specific configurations are
+available:
+
+- ostest
+    This builds the examples/ostest application for execution from FLASH.
+    See examples/README.txt for information about ostest.
+
+- pashello
+
+    Configures to use examples/pashello for execution from FLASH
+    See examples/README.txt for information about pashello.
+
+Check out any README.txt files in these <sub-directory>s.

+This is the output from the z16f target from January 31, 2008

+correct and I suspect some system timing issues.

+z80sim README
+^^^^^^^^^^^^^
+
+This port uses a primitive, emulated Z80 and the SDCC toolchain.
+The instruction set emulator can be found in the NuttX SVN at
+http://nuttx.svn.sourceforge.net/viewvc/nuttx/trunk/misc/sims/z80sim
+
+The SDCC toolchain is available from http://sdcc.sourceforge.net/.  All
+testing has been performed using version 2.6.0 of the SDCC toolchain.
+
+Contents
+^^^^^^^^
+
+  o Configuring NuttX
+  o Building the SDCC toolchain
+  o SDCC Update
+  o Newer SDCC Versions
+
+Configuring NuttX
+^^^^^^^^^^^^^^^^^
+
+  ostest
+    This configuration performs a simple, minimal OS test using
+    examples/ostest.  This can be configurated as follows:
+
+       cd tools
+       ./configure.sh z80sim/ostest
+       cd -
+       . ./setenv.sh
+
+  nsh
+    This configuration file builds NSH (examples/nsh).  This
+    configuration is not functional due to issues with use of the
+    simulated serial driver (see the TODO list).
+
+    This configuration can be selected by:
+
+       cd tools
+       ./configure.sh z80sim/nsh
+       cd -
+       . ./setenv.sh
+
+ pashello
+    Configures to use examples/pashello for execution from FLASH
+    See examples/README.txt for information about pashello.
+
+    This configuration is not usable because the resulting binary
+    is too large for the z80 address space.
+
+    This configuration can be selected by:
+
+       cd tools
+       ./configure.sh z80sim/pashello
+       cd -
+       . ./setenv.sh
+
+Building the SDCC toolchain
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The SDCC toolchain is built with the standard configure/make/make install
+sequence.  However, some special actions are required to generate libraries
+compatible with this build.  First start with the usual steps
+
+  download
+  unpack
+  cd sdcc
+  ./configure
+
+But before making, we need to apply a patch to the SDCC 2.6.0 source
+so that the z80 assembler can handle long symbol names
+
+  Apply sdcc-2.6.0-asz80-symlen.patch
+  cd sdcc/device/lib
+
+Then make the SDCC binaries
+
+  cd sdcc
+  make
+
+and install SDCC:
+
+  sudo make install
+
+SDCC Update
+^^^^^^^^^^^
+
+I have had some problems building sdcc-2.6.0 on my current UBUNTU
+release (9.10).  I had other problems building sdcc-2.9.0 on UBUNTU 9.10.
+I suspect that the newer gcc toolchains are causing problems for these
+older SDCC releases.
+
+A 20091106 snapshot did build with no major problems on UBUNTU 9.10, but
+has some compatibilty problems with the older SDCC compiler.  For one, you
+will need to change the Z80 assember name and options in the Make.defs
+files as follows:
+
+-AS         = as-z80
++AS         = sdasz80
+ 
+-    @$(AS) $(ASFLAGS) $2 $1
++    $(AS) $(ASFLAGS) $1
+
+For another, I had other problems building with that 20091106 that look
+like compiler bugs.  If you are using UBUNTU 9.10, you may have to either
+(1) downgrade your GCC compiler to a version 3.x compiler and use one of
+the older stable releases, or (2) wait for the next stable SDCC release
+after 2.9.0.
+
+See below:  If you wish to continue using the older SDCC toolchain, you
+must now also add CONFIG_SDCC_OLD=y to your configuration file.
+
+Newer SDCC Versions
+^^^^^^^^^^^^^^^^^^^
+
+This is the text of bug 3468951 reported on the SourceForge website:
+
+"Some obsolete stuff in z80sim port," (submitted by Philipp Klaus Krause):
+
+  The simz80 port needs a few updates to work well with current sdcc versions,
+  and has some unecessary stuff:
+
+  * The linker name for Make.defs should be sdldz80
+  * The assembler name for Make.defs should be sdasz80
+  * _asm and _endasm in z80_io.c and z80_irq.c should be replaced by __asm
+    and __endasm
+  * The --stack-auto --int-long-reent --float-reent options or Make.defs should
+     be removed, as they have no effect on sdcc's z80 port
+  * The current assembler AFAIK can handle long symbol names, so the
+    sdcc-2.6.0-asz80-symlen.patch is unnecessary, and it and the corresponding
+    section from the README can be removed.
+
+These changes *have* been incorporated but only partially verified.  In order
+to get a successful compilation, I had to copy stdarg.h out of the SDCC source
+(at sdcc/device/include/stdarg.h) to include/nuttx/stdarg.h.
+
+There are also some library related issues when you get to the final build
+that I have not looked into yet.
+
+If you want to back out these change and continue to use the older toolchain
+in your build, simpy define the following in your configuration file:
+
+  CONFIG_SDCC_OLD=y

+ZDS-II Compiler Versions
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+4.10.1
+  The ZDS-II version 4.10.2 will not compile NuttX.  It reports "internal
+  errors" on one of the files, mm/mm_initialize.c.  Below is a simple work-
+  around.  With this work-around in place, NuttX builds successfully with
+  the 4.10.1 compiler.

+
+4.9.5
+  This is the latest tool version listed on the ZiLOG site for the Z8F6403.
+  However, it uses different compiler command line arguments.
+
+Other Versions
+  If you use any version of ZDS-II other than 4.10.1 or if you install ZDS-II
+  at any location other than the default location, you will have to modify
+  two files:  (1) configs/z8encore000zco/*/setenv.sh and (2)
+  configs/z8encore000zco/*/Make.defs.
+
+Configuration Subdirectories
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- src/ and include/
+    These directories contain common logic for all z8encore000zco
+    configurations.
+
+Variations on the basic z8encore000zco configuration are maintained
+in subdirectories.  To configure any specific configuration, do the
+following steps:
+
+   cd <nuttx-top-directory>/tools
+   ./configure.sh z8encore000zco/<sub-directory>
+   cd <nuttx-top-directgory>
+   make
+
+Where <sub-directory> is the specific board configuration that you
+wish to build.  The following board-specific configurations are
+available:
+
+- ostest
+    This builds the examples/ostest application for execution from FLASH.
+    See examples/README.txt for information about ostest.
+
+Check out any README.txt files in these <sub-directory>s.

+ZDS-II Compiler Versions
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+4.10.1
+  The ZDS-II version 4.10.2 will not compile NuttX.  It reports "internal
+  errors" on one of the files, mm/mm_initialize.c.  Below is a simple work-
+  around.  With this work-around in place, NuttX builds successfully with
+  the 4.10.1 compiler.

+
+4.9.5
+  This is the latest tool version listed on the ZiLOG site for the Z8F6403.
+  However, it uses different compiler command line arguments.
+
+Other Versions
+  If you use any version of ZDS-II other than 4.10.1 or if you install ZDS-II
+  at any location other than the default location, you will have to modify
+  two files:  (1) configs/z8f64200100kit/*/setenv.sh and (2)
+  configs/z8f64200100kit/*/Make.defs.
+
+Configuration Subdirectories
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- src/ and include/
+    These directories contain common logic for all z8f64200100kit
+    configurations.
+
+Variations on the basic z8f64200100kit configuration are maintained
+in subdirectories.  To configure any specific configuration, do the
+following steps:
+
+   cd <nuttx-top-directory>/tools
+   ./configure.sh z8f64200100kit/<sub-directory>
+   cd <nuttx-top-directgory>
+   make
+
+Where <sub-directory> is the specific board configuration that you
+wish to build.  The following board-specific configurations are
+available:
+
+- ostest
+    This builds the examples/ostest application for execution from FLASH.
+    See examples/README.txt for information about ostest.
+
+Check out any README.txt files in these <sub-directory>s.
