+  --------------------------------------
+  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

+  The devkitARM toolchain includes a version of MSYS make.  Make sure that the

   path or will get the wrong version of make.

     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.
 
+    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.

-# CONFIG_PRIORITY_INHERITANCE : Set to enable support for priority
-#   inheritance on mutexes and semaphores. 
-# CONFIG_SEM_PREALLOCHOLDERS: This setting is only used if priority

-# RTC Configuration

-# CONFIG_RTC - Enables general support for a hardware RTC.  Specific

-# 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

-# CONFIG_SEM_PREALLOCHOLDERS: This setting is only used if priority

-# RTC Configuration
-#
-# 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

-#   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

-# CONFIG_ARCH_BOARD_name - for use in C code
-# CONFIG_ENDIAN_BIG - define if big endian (default is little endian)
-# CONFIG_BOARD_LOOPSPERMSEC - for delay loops
-# CONFIG_DRAM_SIZE - Describes the installed DRAM.
-# CONFIG_DRAM_START - The start address of DRAM (physical)
-# CONFIG_DRAM_END - Last address+1 of installed RAM
-# CONFIG_ARCH_IRQPRIO - The STM3220xxx supports interrupt prioritization
-# CONFIG_ARCH_FPU - The STM3220xxx supports a floating point unit (FPU)
-#   (But, unfortunately, GCC does not support it).
-# 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_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_NXFFS: Enable NuttX FLASH file system (NXFF) support.

-# 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

-#   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

-# 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

-#   be disabled by setting this value to zero.
-# CONFIG_SCHED_INSTRUMENTATION - enables instrumentation in 
-#   scheduler to monitor system performance
-# CONFIG_TASK_NAME_SIZE - Spcifies 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

-# CONFIG_JULIAN_TIME - Enables Julian time conversions. You
-#   would only need this if you are concerned about accurate

-# CONFIG_DEV_LOWCONSOLE - Use the simple, low-level serial console
-#   driver (minimul support)

-# CONFIG_PRIORITY_INHERITANCE : Set to enable support for priority
-#   inheritance on mutexes and semaphores. 
-# 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.
-# 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 zero if no more than one thread is expected to wait for
-#   a semaphore.

-# 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_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).

-#   in BCD format.  If CONFIG_RTC_DATETIME is selected, it specifies this

-#   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:

-#   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

-# CONFIG_FAT_MAXFNAME - If CONFIG_FAT_LFN is defined, then the

-# CONFIG_RTC_HIRES - If CONFIG_RTC_DATETIME not selected, then the simple,

-#   in BCD format.  If CONFIG_RTC_DATETIME is selected, it specifies this

-#   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
