Programming and Debugging
89+
*************************
90+
91+
Flashing
92+
========
93+
The MAX32650 MCU can be flashed by connecting an external debug probe to the
94+
SWD port. SWD debug can be accessed through the Cortex 10-pin connector, J3.
95+
Logic levels are fixed to VDDIO (1.8V).
96+
97+
Once the debug probe is connected to your host computer, then you can simply run the
98+
``west flash`` command to write a firmware image into flash.
99+
100+
.. note::
101+
102+
This board uses OpenOCD as the default debug interface. You can also use
103+
a Segger J-Link with Segger's native tooling by overriding the runner,
104+
appending ``--runner jlink`` to your ``west`` command(s). The J-Link should
105+
be connected to the standard 2*5 pin debug connector (J3) using an
106+
appropriate adapter board and cable
107+
108+
Debugging
109+
=========
110+
Please refer to the `Flashing`_ section and run the ``west debug`` command
111+
instead of ``west flash``.
