Programming & Debugging

The pic32cm_jh01_cpro board supports the runners and associated west commands listed below.

jlink ✅ ✅ ✅ ✅ ✅
pyocd ✅ (default) ✅ (default) ✅ ✅ ✅

Setting Up the Debug Interface

PyOCD Setup

  1. Install Device Pack

    • Add support for the PIC32CM family devices using the following command:

    pyocd pack install pic32cm

  2. Verify Device Support

    • Confirm that the target is recognized:

    pyocd list --targets

    • You should see an entry similar to:

    pic32cm5164jh01100        Microchip                PIC32CM5164JH01100           PIC32CM-JH   pack

  3. Connect the Board

    • Connect the DEBUG USB port on the board to your host machine.

    • This connection power up the board and provides access to the on-board Embedded Debugger (EDBG), which enables programming and debugging of the target microcontroller through PyOCD.

Building and Flashing the Application

  1. Build the Application

    You can build a sample Zephyr application, such as Blinky, using the west tool. Run the following commands from your Zephyr workspace:

    west build -b pic32cm_jh01_cpro -p -s samples/basic/blinky

    This will build the Blinky application for the pic32cm_jh01_cpro board.

  2. Flash the Device

    Once the build completes, flash the firmware using:

    west flash

    By default, this command uses the PyOCD runner to program the device.

    If both the J-Link probe (connected via the CORTEX DEBUG header) and the PyOCD supported debug interface (connected through the DEBUG USB port) are available, you can explicitly select the desired runner as shown below:

    west flash --runner jlink

    or

    west flash --runner pyocd

    This ensures the application is flashed using the respective connected interface.

  3. Observe the Result

    After flashing, LED0 on the board should start blinking, indicating that the application is running successfully.
