Programming and Debugging
*************************

Applications for the ``blueclover_plt_demo_v2/nrf52832`` board configuration
can be built and flashed in the usual way (see :ref:`build_an_application`
and :ref:`application_run` for more details).

Flashing
========

Flashing Zephyr onto the ``blueclover_plt_demo_v2/nrf52832`` board requires
an external programmer. The programmer is attached to the SWD header.

Build the Zephyr kernel and the :zephyr:code-sample:`led-strip` sample application.

   .. zephyr-app-commands::
      :zephyr-app: samples/drivers/led_apa102
      :board: blueclover_plt_demo_v2/nrf52832
      :goals: build
      :compact:

Flash the image.
