chipKIT Wi-FIRE board
|
||
|
|
(https://chipkit.net/wiki/index.php?title=ChipKIT_Wi-Fire) features
|
||
|
|
the Microchip PIC32MZ2048EFG100 MCU, Microchip MRF24WG0MA Wi-Fi module,
|
||
|
|
USB 2.0 Full-Speed / Hi-Speed OTG controller, Micro SD card connector etc.
|
||
|
|
The PIC32MZ2048EFG100 is a 200 MHz 32-bit MIPS M5150 operation with 2MB Flash
|
||
|
|
memory and 512KB RAM.

Toolchain
|
||
|
|
=========
|
||
|
|
|
||
|
|
The following Toolchain options have been tested and confirmed to work:
|
||
|
|
|
||
|
|
CONFIG_MIPS32_TOOLCHAIN_PINGUINOL - Pinquino Toolchain
|
||
|
|
for Linux
|
||
|
|
CONFIG_MIPS32_TOOLCHAIN_SOURCERY_CODEBENCH_LITE - Sourcery CodeBench Lite
|
||
|
|
Toolchain for Linux
|
||
|
|
|
||
|
|
Pinquino Toolchain can be downloaded here:
|
||
|
|
|
||
|
|
https://github.com/PinguinoIDE/pinguino-compilers
|
||
|
|
|
||
|
|
Sourcery CodeBench Lite Toolchain for Linux can be downloaded and
|
||
|
|
installed as follows:
|
||
|
|
|
||
|
|
$ wget https://sourcery.mentor.com/GNUToolchain/package12725/public/mips-sde-elf/mips-2014.05-24-mips-sde-elf-i686-pc-linux-gnu.tar.bz2
|
||
|
|
$ sudo tar xvjf mips-2014.05-24-mips-sde-elf-i686-pc-linux-gnu.tar.bz2 \
|
||
|
|
-C /usr/local
|

Building NuttX for the chipKIT Wi-FIRE board
|
||
|
|
============================================
|
||
|
|
|
||
|
|
$ cd nuttx
|
||
|
|
$ make apps_distclean
|
||
|
|
$ make distclean
|
||
|
|
$ ./tools/configure.sh -l chipkit-wifire:nsh
|
||
|
|
$ make
|
||
|
|
|
||
|
|
Programming Flash
|
||
|
|
=================
|
||
|
|
|
||
|
|
CAUTION:
|
||
|
|
|
||
|
|
Currently the pre-installed bootloader of the chipKIT Wi-FIRE board
|
||
|
|
is not supported in this NuttX configuration. Doing the following
|
||
|
|
steps will erase the factory installed bootloader in the Flash
|
||
|
|
memory! If you are going to recover the bootloader later on your
|
||
|
|
chipKIT Wi-FIRE board, the original chipKIT bootloader can be found here:
|
||
|
|
https://reference.digilentinc.com/_media/chipkit_wifire/chipkit-wifire-v01000303.zip
|
||
|
|
|
||
|
|
Flash memory can be programmed by pic32prog utility
|
||
|
|
(https://github.com/sergev/pic32prog.git) and PICkit 2 programmer
|
||
|
|
(via 6-pin ICSP (JP1) of chipKIT Wi-FIRE board) as follows:
|
||
|
|
|
||
|
|
$ sudo pic32prog nuttx.hex
|
||
|
|
|
||
|
|
Serial console
|
||
|
|
==============
|
||
|
|
|
||
|
|
Connect USB cable from your PC to connector J1 (labeled "UART") of
|
||
|
|
the chipKIT Wi-FIRE board.
|
||
|
|
Then use some serial console client (minicom, picocom, teraterm, etc)
|
||
|
|
configured to 115200 8n1 without software or hardware flow control.
|
||
|
|
|
||
|
|
Reset the board and you should see NuttX starting in the serial.
