*
|

* Description:
|

* These external functions must be provided by board-specific logic. They are
|
||||
* implementations of the select, status, and cmddata methods of the SPI interface
|
||||
* defined by struct spi_ops_s (see include/nuttx/spi.h). All other methods
|
||||
* including up_spiinitialize()) are provided by common PIC32MX logic. To use
|
||||
* this common SPI logic on your board:
|
||||
*
|
||||
* 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.

||||
