PIC32MX Configuration Options
Configurations
Toolchains
==========
I am using the free, LITE version of the PIC32MX toolchain available
for download from the microchip.com web site. I am using the Windows
version. This is only toolchain currently supported in these
configurations, but it should be a simple matter to adapt to other
toolchains by modifying the Make.defs file include in each configuration.
version. The MicroChip toolchain is the only toolchaing currently
supported in these configurations, but it should be a simple matter to
adapt to other toolchains by modifying the Make.defs file include in
each configuration.
Toolchain Options:
CONFIG_PIC32MX_MICROCHIPW - MicroChip full toolchain for Windows
CONFIG_PIC32MX_MICROCHIPL - MicroChip full toolchain for Linux
CONFIG_PIC32MX_MICROCHIPW_LITE - MicroChip LITE toolchain for Windows
CONFIG_PIC32MX_MICROCHIPL_LITE - MicroChip LITE toolchain for Linux
Windows Native Toolchains
NOTE: 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 not 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
PIC32MX Configuration Options
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
General Architecture Settings:
CONFIG_ARCH - Identifies the arch/ subdirectory. This should
be set to:
CONFIG_ARCH=mips
CONFIG_ARCH_family - For use in C code:
CONFIG_ARCH_MIPS=y
CONFIG_ARCH_architecture - For use in C code:
CONFIG_ARCH_MIPS32=y
CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
CONFIG_ARCH_CHIP=pic32mx
CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
chip:
CONFIG_ARCH_CHIP_PIC32MX460F512L=y
CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
hence, the board that supports the particular chip or SoC.
CONFIG_ARCH_BOARD=pcblogic-pic32mx
CONFIG_ARCH_BOARD_name - For use in C code
CONFIG_ARCH_BOARD_PCBLOGICPIC32MX=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_DRAM_END=(CONFIG_DRAM_START+CONFIG_DRAM_SIZE)
CONFIG_ARCH_IRQPRIO - The PIC32MXx supports interrupt prioritization
CONFIG_ARCH_IRQPRIO=y
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
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_LEDS - Use LEDs to show state. 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 calibratre
CONFIG_ARCH_LOOPSPERMSEC. You simply use a stop watch to measure
the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
the delay actually is 100 seconds.

# CONFIG_DEBUG - enables built-in debug options
# CONFIG_DEBUG_VERBOSE - enables verbose debug output
# CONFIG_DEBUG_SYMBOLS - build without optimization and with
# debug symbols (needed for use with a debugger).
# CONFIG_MM_REGIONS - If the architecture includes multiple
# regions of memory to allocate from, this specifies the
# 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

# 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
# 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
