+ * defined by struct spi_ops_s (see include/nuttx/spi.h). All other methods

+ *
+ * 1. Provide logic in pic32mx_boardinitialize() to configure SPI/SSP chip select
+ * pins.
+ * 2. Provide pic32mx_spiNselect() and pic32mx_spiNstatus() functions
+ * in your board-specific logic. These functions will perform chip selection
+ * and status operations using GPIOs in the way your board is configured.
+ * 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
+ * pic32mx_spiNcmddata() functions in your board-specific logic. These
+ * functions will perform cmd/data selection operations using GPIOs in the way
+ * your board is configured.
+ * 3. Add a call to up_spiinitialize() in your low level application
+ * initialization logic
+ * 4. The handle returned by up_spiinitialize() may then be used to bind the
+ * SPI driver to higher level logic (e.g., calling
+ * mmcsd_spislotinitialize(), for example, will bind the SPI driver to
+ * the SPI MMC/SD driver).

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.
+

+Configurations
+^^^^^^^^^^^^^^
+
+Each PIC32MX configuration is maintained in a sudirectory and can be
+selected as follow:

+ . ./setenv.sh
+
+Where <subdir> is one of the following:

+# 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.

+# 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
