Overview

The MAX32660 evaluation system offers a compact development platform that provides access to all the features of the MAX32660 in a tiny, easy to use board. A MAX32625PICO-based debug adapter comes attached to the main board. It can be snapped free when programming is complete. The debug module supports an optional 10-pin Arm® Cortex® debug connector for DAPLink functionality. Combined measurements are 0.65in x 2.2in, while the main board alone measures 0.65in x 0.95in. External connections terminate in a dual-row header footprint compatible with both thru-hole and SMT applications. This board provides a powerful processing subsystem in a very small space that can be easily integrated into a variety of applications.

The Zephyr port is running on the MAX32660 MCU.

Programming and Debugging

.. zephyr:board-supported-runners::

Flashing

An Arm® debug access port (DAP) provides an external interface for debugging during application development. The DAP is a standard Arm CoreSight® serial wire debug port, uses a two-pin serial interface (SWDCLK and SWDIO), and is accessed through 10-pin header (J4).

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.

.. 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 (J3) using an appropriate adapter board and cable.

Debugging

Please refer to the Flashing_ section and run the west debug command instead of west flash.
