===================
|
||||
|
||||
The `Adafruit Feather nRF52840 Express Learn site`_ has detailed
|
||||
information about the board including `pinouts`_ and the `schematic`_.

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.
