Setting Up the Debug Interface

PyOCD Setup

  1. Install Device Pack

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

    .. code-block:: console

    pyocd pack install pic32cm

  2. Verify Device Support

    • Confirm that the target is recognized:

    .. code-block:: console

    pyocd list --targets

    • You should see an entry similar to:

    .. code-block:: text

    pic32cm6408pl10048 Microchip PIC32CM6408PL10048 PIC32CM-PL 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:

    .. code-block:: console

    west build -b pic32cm_pl10_cnano -p -s samples/basic/blinky

    This will build the Blinky application for the pic32cm_pl10_cnano board.

  2. Flash the Device

    Once the build completes, flash the firmware using:

    .. code-block:: console

    west flash

  3. Observe the Result

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