# 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)
# NOTE: The PIC32MX is always 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 PIC32MX 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 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_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

# 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.
# 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: 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
# 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
# option will enable a limited form of memory mapping that is
# implemented by copying whole files into memory.
