Flashing ======== The MAX32670 EVKIT integrates a MAX32625PICO based debugger for DAPLink functionality. Once the debug probe is connected to your host computer, then you can simply run the ``west flash`` command to write a firmware image into flash. Debugging ========= Please refer to the `Flashing`_ section and run the ``west debug`` command instead of ``west flash``.
