# architecture selection
#
# CONFIG_ARCH - identifies the arch subdirectory and, hence, the
#   processor architecture.
# CONFIG_ARCH_family - for use in C code.  This identifies the
#   particular chip family that the architecture is implemented
#   in.
# CONFIG_ARCH_architecture - for use in C code.  This identifies the
#   specific architecture within the chip family.
# 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_BOARD_LOOPSPERMSEC - for delay loops
# CONFIG_DRAM_SIZE - Describes the installed DRAM.
# CONFIG_DRAM_START - The start address of DRAM (physical)
# CONFIG_ARCH_IRQPRIO - The STM3240xxx supports interrupt prioritization
# CONFIG_ARCH_FPU - The STM3240xxx supports a floating point unit (FPU).
# 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 calibrate
#   CONFIG_BOARD_LOOPSPERMSEC.  You simply use a stop watch to measure
#   the 100 second delay then adjust CONFIG_BOARD_LOOPSPERMSEC until
#   the delay actually is 100 seconds.

#   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 - 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
#   time conversions in the past or in the distant future.
# CONFIG_JULIAN_TIME - Enables Julian time conversions. You

# CONFIG_DEV_LOWCONSOLE - Use the simple, low-level serial console
#   driver (minimul support)
# 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. 
# 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 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.
# 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_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 - Enable the waitpid() API
# CONFIG_SCHED_ATEXIT - Enabled the atexit() API

# Filesystem configuration
#
# CONFIG_FS_FAT - Enable FAT filesystem support
# CONFIG_FAT_SECTORSIZE - Max supported sector size
# 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_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.
# 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_FS_RAMMAP - For file systems that do not support XIP, this

# 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
