Programming and Debugging


.. zephyr:board-supported-runners::

The board must be programmed using an external SWD probe (for example, a Segger J-Link) connected to the SWDIO, SWCLK, VDD, and GND pads.

Flashing

Follow the instructions in the :ref:nordic_segger page to install and configure the required software. Then build and flash applications as usual (see :ref:build_an_application and :ref:application_run for more details).

Here is an example for the :zephyr:code-sample:blinky application:

.. zephyr-app-commands:: :zephyr-app: samples/basic/blinky :board: holyiot_21014 :goals: build flash

Testing the LED and button

You can test the board peripherals with the following samples:
