-# 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.
-# CONFIG_ARCH_DMA - Support DMA initialization

-# CONFIG_DEBUG - enables built-in debug options
-# CONFIG_DEBUG_VERBOSE - enables verbose debug output
-# CONFIG_DEBUG_SYMBOLS - build without optimization and with

-# CONFIG_HAVE_CXX - Enable support for C++

-# for initialization of static C++ instances for this architecture
-# and for the selected toolchain (via up_cxxinitialize()).
-# CONFIG_MM_REGIONS - If the architecture includes multiple

-# number of memory regions that the memory manager must
-# handle and enables the API mm_addregion(start, end);
-# 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 - Spcifies that maximum size of a

-# CONFIG_START_YEAR, CONFIG_START_MONTH, CONFIG_START_DAY -
-# Used to initialize the internal time logic.

-# CONFIG_JULIAN_TIME - Enables Julian time conversions. You

-# time conversion in the distand past. You must also define

-# 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

-# CONFIG_FAT_MAXFNAME - If CONFIG_FAT_LFN is defined, then the

-# a lot of memory (especially stack space). If you are willing

-# 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

-# 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
