| 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_ra2l1 |
| :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_ra2l1 |
| :maybe-skip-config: |
| :goals: debug |
| |
| Or you can use Segger Ozone (`Segger Ozone Download`_) for a visual debug interface |
| |
| Once downloaded and installed, open Segger Ozone and configure the debug project |
| like so: |
| |
| * Target Device: R7FA2L1AB |
| * Target Interface: SWD |
| * Target Interface Speed: 4 MHz |
| * Host Interface: USB |
| * Program File: <path/to/your/build/zephyr.elf> |
