@brief Support for the Digilent PIC32 WiFire
|
|
@deprecated Will not be available after the 2022.07 release. This includes
|
|
all MIPS based boards and cpus.
|
|
|
|
## Overview
|
|
|
|
The ChipKit Wifire is a development board by Digilent featuring a PIC32MZ and a Wifi module (MRF24WG0MA).
|
|
General information about the board can be found [here](https://store.digilentinc.com/wi-fire-wifi-enabled-pic32mz-microcontroller-board/)
|
|
Please do not use board rev A or B as they use a different MCU (PIC32MZ2048ECG100).

## Using UART
|
|
|
|
This board opens a serial interface through the USB automatically.
|
|
|
|
## Flashing the device
|
|
|
|
There are three ways to flash the MCU:
|
|
* Using MPLAB-IPE and a PICkit 3 (The RIOT build generates a hexfile
|
|
compatible with MPLAB-IPE)
|
|
* Using pic32prog and a PICkit 2 or a PICkit 3 (other devices might be
|
|
supported by pic32prog but were not tested).
|
|
* Using a SEGGER J-Link probe. JTAG pins are available on the JP3 connector.
|
|
|
|
## Supported Toolchains
|
|
|
|
For using the pic32-wifire board we strongly recommend the usage of the
|
|
[Codescape GNU Tools](https://codescape.mips.com) toolchain.
