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. 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
Loading NuttX with PICkit2
==========================
NOTE: You need a PICKit3 if you plan to use the MPLAB debugger! The PICKit2
can, however, still be used to load problems. Instructions for the PICKit3
are similar.
Intel Hex Forma Files:
----------------------
When NuttX is built it will produce two files in the top-level NuttX
directory:
1) nuttx - This is an ELF file, and
2) nuttx.ihx - This is an Intel Hex format file. This is controlled by
the setting CONFIG_INTELHEX_BINARY in the .config file.
The PICkit tool wants an Intel Hex format file to burn into FLASH.
However, there are two problems with the generated nutt.ihx:
1) The tool expects Intel Hex format files to be named *.hex. This
is not a significant issue. However, just renaming the file to
nuttx.hex is *not* sufficient. There is another problem:
2) The tool expects the nuttx.hex file to contain physical addresses.
But the nuttx.ihx file generated from the top-level make will have
address in the KSEG0 and KSEG1 regions.
tools/mkpichex:
---------------
There is a simple tool in the configs/pic32-starterkit/tools directory
that can be used to solve both issues with the nuttx.ihx file. But,
first, you must build the the tools:
cd configs/pic32-starterkit/tools
make
Now you will have an excecutable file call mkpichex (or mkpichex.exe on
Cygwin). This program will take the nutt.ihx file as an input, it will
convert all of the KSEG0 and KSEG1 addresses to physical address, and
it will write the modified file as nuttx.hex.
To use this file, you need to do the following things:
. ./setenv.sh # Source setenv.sh. Among other this, this script
# will add configs/pic32-starterkit/tools to your
# PATH variable
make # Build nuttx and nuttx.ihx
mkpichex $PWD # Convert nuttx.ihx to nuttx.hex. $PWD is the path
# to the top-level build directory. It is the only
# required input to mkpichex.
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_PIC32MX795F512L=y
CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
hence, the board that supports the particular chip or SoC.
CONFIG_ARCH_BOARD=pic32-starterkit
CONFIG_ARCH_BOARD_name - For use in C code
CONFIG_ARCH_BOARD_PIC32_STARTERKIT=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_SIG_SIGWORK - The signal number that will be used to wake-up
# the worker thread. Default: 4

*
* 1. Provide logic in pic32mx_boardinitialize() to configure SPI/SPI chip select
* pins.
* 2. Provide pic32mx_spi2select() and pic32mx_spi2status() functions
* in your board-specific logic. These functions will perform chip selection
* and status operations using GPIOs in the way your board is configured.
* 3. Add a calls 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).

* 04, Extended Linear Address Record, allowing for fully 32 bit addressing.
* The address field is 0000, the byte count is 02. The two data bytes

* 05, Start Linear Address Record. The address field is 0000, the byte
