MAX32672FTHR
4+
############
5+
6+
Overview
7+
********
8+
The MAX32672FTHR is a rapid development platform that helps engineers quickly implement complex
9+
sensor solutions using the MAX32672 Arm® Cortex®-M4. The board also includes the MAX8819 PMIC for
10+
battery and power management. The form factor is a small, 0.9in by 2.6in, dual row header footprint
11+
that is compatible with Adafruit® FeatherWing peripheral expansion boards. The board includes
12+
an OLED display, a RGB indicator LED, and a user pushbutton. The MAX32672FTHR provides
13+
a power-optimized flexible platform for quick proof-ofconcepts and early software development
14+
to enhance time to market.
15+
16+
The Zephyr port is running on the MAX32672 MCU.

Programming and Debugging
183+
*************************
184+
185+
Flashing
186+
========
187+
188+
The MAX32625 microcontroller on the board is flashed with DAPLink firmware at the factory.
189+
It allows debugging and flashing the MAX32672 Arm Core over USB.
190+
191+
Once the debug probe is connected to your host computer, then you can simply run the
192+
``west flash`` command to write a firmware image into flash.
193+
194+
Debugging
195+
=========
196+
197+
Please refer to the `Flashing`_ section and run the ``west debug`` command
198+
instead of ``west flash``.
