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.
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:
