Supported Features

Programming and Debugging

.. zephyr:board-supported-runners::

The Adafruit Feather RP2040 Adalogger board does not expose the SWDIO and SWCLK pins, so programming must be done via the USB port. Press and hold the BOOT button, and then press the RST button, and the device will appear as a USB mass storage unit. Building your application will result in a :file:build/zephyr/zephyr.uf2 file. Drag and drop the file to the USB mass storage unit, and the board will be reprogrammed.

For more details on programming RP2040-based boards, see :ref:rpi_pico_programming_and_debugging.

Flashing
