-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 detron/<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.
-
-Detron 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=detron (for the Detron board)
-
-	CONFIG_ARCH_BOARD_name - For use in C code
-
-	   CONFIG_ARCH_BOARD_DETRON=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_DRAM_END - Last address+1 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

-	   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

-Configurations
-^^^^^^^^^^^^^^
-
-Each Detron configuration is maintained in a sudirectory and can be
-selected as follow:
-
-	cd tools
-	./configure.sh detron/<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.
-
-  nsh:
-    Configures the NuttShell (nsh) located at examples/nsh.  The
-    Configuration enables only the serial  NSH interfaces.

-#   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: 50
-# 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

-#  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: 50

-#  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

-#   semaphore.
-# CONFIG_SEM_NNESTPRIO.  If priority inheritance is enabled,

-#   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: 50
-# 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
