Supported Features

.. zephyr:board-supported-hw::

Programming and Debugging

.. zephyr:board-supported-runners::

Building

#. Build :zephyr:code-sample:hello_world application as you would normally do.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: rts5817_maa_evb :goals: build

#. The file zephyr.rts5817.bin will be created if the build system can build successfully. This binary image can be found under file "build/zephyr/".

Flashing

#. Short the two pins of J6 to enter force rom mode (see RTS5817MAA_EVB_User_Guide_). #. Connect the board to your host computer using USB. #. Use west flash command to flash the image. #. Disconnect the two pins of J6 and reboot, The :zephyr:code-sample:hello_world application is running.
