Programming and Debugging

The ek_ra4l1 board supports the runners and associated west commands listed below.

flash debug

Applications for the ek_ra4l1 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.

Flashing

Program can be flashed to EK-RA4L1 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 describe in EK-RA4L1 - User’s Manual

  3. Execute west command

west flash -r jlink
