Overview
|
|
********
|
|
The MAX32670 evaluation kit (EV kit) provides a platform for evaluation capabilities
|
|
of the MAX32670. The MAX32670 is an ultra-low-power, cost-effective, highly reliable
|
|
32-bit microcontroller that enables designs with complex sensor processing without
|
|
compromising battery life. It combines a flexible and versatile power management unit
|
|
with the powerful Arm® Cortex®-M4 core with floating point unit (FPU).
|
|
The MAX32670 also offers legacy designs an easy and cost optimal upgradepath
|
|
from 8-bit or 16-bit microcontrollers.
|
|
|
|
The Zephyr port is running on the MAX32670 MCU.

Programming and Debugging
|
|
*************************
|
|
|
|
Flashing
|
|
========
|
|
|
|
The MAX32670 EVKIT integrates a MAX32625PICO based debugger for DAPLink functionality.
|
|
|
|
|
|
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.
|
|
|
|
Debugging
|
|
=========
|
|
|
|
Please refer to the `Flashing`_ section and run the ``west debug`` command
|
|
instead of ``west flash``.
