175************************* 176 177Flashing 178======== 179 180The MAX32670 EVKIT integrates a MAX32625PICO based debugger for DAPLink functionality. 181 182 183Once the debug probe is connected to your host computer, then you can simply run the 184``west flash`` command to write a firmware image into flash. 185 186Debugging 187========= 188 189Please refer to the `Flashing`_ section and run the ``west debug`` command 190instead of ``west flash``. 191 192References 193********** 194 195- `MAX32670EVKIT web page`_ 196 197.. _MAX32670EVKIT web page: 198
