Flashing

Using UF2

Here is an example of building the sample for enabling USB console.

.. zephyr-app-commands:: :zephyr-app: samples/subsys/usb/console :board: framework_ledmatrix :goals: build :compact:

You must flash the LED Matrix with an UF2 file. One option is to use West (Zephyr’s meta-tool). To enter the UF2 flashing mode, remove the module flip the dip switch 2 and assemble it again. It will appear on the host as a mass storage device. At this point you can flash the image file by running:

.. code-block:: bash

west flash

After flashing, switch the DIP switch back again to run the firmware.

Alternatively, you can locate the generated :file:build/zephyr/zephyr.uf2 file and simply drag-and-drop to the device after entering the UF2 flashing mode.
