.. zephyr:board:: mm_feather
Overview
The SwiftIO Feather board, designed by MadMachine is
designed with support for the modern Swift language <https://docs.swift.org/swift-book/>_. Zephyr provides basic
low-level capabilities for the SwiftIO Feather board. Swift application would
run on top of Zephyr. More information about the board can be found

Programming and Flashing
.. zephyr:board-supported-runners::
Build and flash applications as usual (see :ref:build_an_application and
:ref:application_run for more details).
Connect a USB-to-serial adapter from your PC to corresponding UART pins of SwiftIO Feather.
Use the following settings with your serial terminal of choice (minicom, putty, etc.):
Here is an example for the :zephyr:code-sample:hello_world application.
Connect a DAPLink debugger from your PC to corresponding SWD pins of SwiftIO Feather.
.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: mm_feather :goals: flash
Open a serial terminal, reset the board (press the "reset" button), and you should see the following message in the terminal:
.. code-block:: console
*** Booting Zephyr OS build v2.6.0-rc1-301-gd9c666a5abf8 *** Hello World! mm_feather
Here is an example for the :zephyr:code-sample:hello_world application.
.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: mm_feather :goals: debug
Open a serial terminal, step through the application in your debugger, and you should see the following message in the terminal:
.. code-block:: console
*** Booting Zephyr OS build v2.6.0-rc1-301-gd9c666a5abf8 *** Hello World! mm_feather
