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 no 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
|
|

|
|
|
|
|
|
- An external application board with a regulated DC power supply that
|
|
|
|
|
|
provides +5V can be connected to the J2 application board connector
|
|
|
|
|
|
that is provided on the bottom side of the board.

|
|
Power can be supplied to the Multimedia Expansion Board through the DC
|
|
|
|
|
|
connector located on the Multimedia Expansion Board... By connecting
|
|
|
|
|
|
9-14V power supply to the DC connector, the Multimedia Expansion Board
|
|
|
|
|
|
and starter kit will receive the proper voltages. The user can also
|
|
|
|
|
|
supply power via the starter kit. However, if the application uses
|
|
|
|
|
|
multiple features of the Multimedia Expansion Board, it is recommended
|
|
|
|
|
|
to use 9-14V power supply."

On Board Debug Support
|
|
|
|
|
|
======================
|
|
|
|
|
|
|
|
|
|
|
|
The PIC32 Ethernet Starter Kit includes a PIC32MX440F512H USB microcontroller
|
|
|
|
|
|
that provides debugger connectivity over USB. The PIC32MX440F512H is hard-wired
|
|
|
|
|
|
to the PIC32 device to provide two types of protocol translation:
|
|
|
|
|
|
|
|
|
|
|
|
- I/O pins of PIC32MX440F512H to the ICSP<53> pins of the PIC32
|
|
|
|
|
|
- I/O pins of PIC32MX440F512H to the JTAG pins of the PIC32
|
|
|
|
|
|
|
|
|
|
|
|
The PIC32 Ethernet Starter Kit currently uses the JTAG pins of the PIC32 device for
|
|
|
|
|
|
programming and debugging.

Creating Compatible NuttX HEX files

Intel Hex Format 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.
|
|
|
|
|
|
|
|
|
|
|
|
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.

[[Warning: This all sounds great, but the fact is that I have not yet
|
|
|
|
|
|
gotten any serial UART output to work from the MEB.]]
|

|
|
|
|
|

|
|
|
|
A serial console is not required to use NuttX. However, all of the
|
|
|
|
|
|
Nuttx example code in the apps/examples assumes that you have a
|
|
|
|
|
|
serial console. The Ethernet Starter Kit(even with the MEB) does not
|
|
|
|
|
|
have any RS-232 connector needed to drive the serial console.
|
|
|
|
|
|
|
|
|
|
|
|
Raw UART signals are available at the MEB's PICtail connector, however,
|
|
|
|
|
|
and can be connected to an external MAX2232 board to get a serial console.
|
|
|
|
|
|
The defconfig files are set up to use UART2. So the proper connections
|
|
|
|
|
|
would be:

|
|

J2 is the connector at the bottom of the Ethernet start kit that

mates the Ethernet Starter kit to the MEB. The MEB then makes the

|
|
|
|
|
General Architecture Settings:
|
|
|
|
|
|
|
|
|
|
|
|
CONFIG_ARCH - Identifies the arch/ subdirectory. This should
|
|
|
|
|
|
be set to:
|
|
|
|
|
|
|
|
|
|
|
|
CONFIG_ARCH=mips
|
|
|
|
|
|
|

|
|
|
|
|
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_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.
