Programming and debugging

Building & Flashing

You can build and flash an application with onboard J-Link debug adapter. Building an Application and Run an Application for more details).

Here is an example for building and flashing the Blinky application.

# From the root of the zephyr repository
west build -b ek_ra2a1 samples/basic/blinky
west flash

Debugging

Debugging also can be done with onboard J-Link debug adapter. The following command is debugging the Blinky application. Also, see the instructions specific to the debug server that you use.

# From the root of the zephyr repository
west build -b ek_ra2a1 samples/basic/blinky
west debug
