Programming and Debugging

Applications for the ek_ra8p1 board configuration can be built, flashed, and debugged in the usual way. See Building an Application and Run an Application for more details on building and running.

Here is an example for the Hello World application on CM85 core.

# From the root of the zephyr repository
west build -b ek_ra8p1/r7ka8p1kflcac/cm85 samples/hello_world
west flash

Open a serial terminal, reset the board (press the S3 button), and you should see the following message in the terminal:

***** Booting Zephyr OS v4.2.0-xxx-xxxxxxxxxxxxx *****
Hello World! ek_ra8p1/r7ka8p1kflcac/cm85

Flashing

Program can be flashed to EK-RA8P1 via the on-board SEGGER J-Link debugger. SEGGER J-link’s drivers are available at https://www.segger.com/downloads/jlink/

To flash the program to board

  1. Connect to J-Link OB via USB port to host PC

  2. Make sure J-Link OB jumper is in default configuration as described in EK-RA8P1 - User’s Manual

  3. Execute west command

    west flash -r jlink
