-Programming and Debugging
-*************************
-
-Applications for the ``adafruit_feather_nrf52840`` 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 ``adafruit_feather_nrf52480`` board requires
-an external programmer. The programmer is attached to the SWD header.
-
-Build the Zephyr kernel and the :ref:`blinky-sample` sample application.
-
-   .. zephyr-app-commands::
-      :zephyr-app: samples/blinky
-      :board: adafruit_feather_nrf52840
-      :goals: build
-      :compact:
-
-Flash the image.
-
-   .. zephyr-app-commands::
-      :zephyr-app: samples/blinky
-      :board: adafruit_feather_nrf52840
-      :goals: flash
-      :compact:
-
-You should see the the red LED blink.
