| Programming and Debugging |
| ************************* |
| |
| .. zephyr:board-supported-runners:: |
| |
| Flashing |
| ======== |
| |
| The MAX32655 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, JH3. |
| 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. To perform a full erase, |
| pass the ``--erase`` option when executing ``west 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 (JW3) using an |
| appropriate adapter board and cable. |
| |
| Debugging |
| ========= |
| |
| Please refer to the `Flashing`_ section and run the ``west debug`` command |
| instead of ``west flash``. |
