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

   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.

J-Link Setup

1. Install J-Link Software

   • Download and install the J-Link software_ tools from Segger.
   • Make sure the installed J-Link executables (e.g., JLink, JLinkGDBServer) are available in your system's PATH.

2. Connect the Board

   • Connect the J32 Debug Probe_ to the board's CORTEX DEBUG header.
   • Connect the other end of the J32 Debug Probe to your host machine (PC) via USB.
   • Connect the DEBUG USB port on the board to your host machine to power up the board.

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_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:

   .. code-block:: console

   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:

   .. code-block:: console

   west flash --runner jlink

   or

   .. code-block:: console

   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.
