MAX32670EVKIT
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.
