Flashing

The MAX32650 MCU can be flashed by connecting an external debug probe to the SWD port. SWD debug can be accessed through the Cortex 10-pin connector, J3. Logic levels are fixed to VDDIO (1.8V).

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.

.. note::

This board uses OpenOCD as the default debug interface. You can also use a Segger J-Link with Segger's native tooling by overriding the runner, appending --runner jlink to your west command(s). The J-Link should be connected to the standard 2*5 pin debug connector (J3) using an appropriate adapter board and cable

Debugging

Please refer to the Flashing_ section and run the west debug command instead of west flash.
