| 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: |
