Building & Flashing

You can build and flash an application with onboard J-Link debug adapter. :ref:build_an_application and :ref:application_run for more details.

Here is an example for building and flashing the :zephyr:code-sample:blinky application.

.. zephyr-app-commands:: :zephyr-app: samples/basic/blinky :board: ek_ra2a1 :goals: build flash

Debugging

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

.. zephyr-app-commands:: :zephyr-app: samples/basic/blinky :board: ek_ra2a1 :maybe-skip-config: :goals: debug
