Programming and Debugging
|
||||
*************************
|
||||
|
||||
Applications for the ``croxel_cx1825/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 ``croxel_cx1825_nrf52840`` board requires
|
||||
an external programmer. The programmer is attached to the SWD header.
|
||||
|
||||
Build the Zephyr kernel and the :zephyr:code-sample:`blinky` sample application.
|
||||
|
||||
.. zephyr-app-commands::
|
||||
:zephyr-app: samples/basic/blinky
|
||||
:board: croxel_cx1825/nrf52840
|
||||
:goals: build
|
||||
:compact:
|
||||
|
||||
Flash the image.
|
||||
|
||||
.. zephyr-app-commands::
|
||||
:zephyr-app: samples/basic/blinky
|
||||
:board: croxel_cx1825/nrf52840
|
||||
:goals: flash
|
||||
:compact:
|
||||
|
||||
You should see the red LED blink.
