Programming and Debugging

.. zephyr:board-supported-runners::

Applications for the cpkcor_ra8d1b board can be built, flashed, and debugged in the usual way. See :ref:build_an_application and :ref:application_run for more details on building and running.

Note: Only support from SDK v0.16.6 in which GCC for Cortex Arm-M85 was available. To build for CPKCOR-RA8D1B user need to get and install GNU Arm Embedded toolchain from https://github.com/zephyrproject-rtos/sdk-ng/releases/tag/v0.16.6

Flashing

Program can be flashed to CPKCOR-RA8D1B via the on-board SEGGER J-Link debugger.

To flash the program to board

Connect to J-LINK OB via USB port to host PC
Execute west command

.. code-block:: console
```
 west flash
```

Debugging

You can debug an application in the usual way. Here is an example for the :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: cpkcor_ra8d1b :maybe-skip-config: :goals: debug
