AD-APARD32690-SL

Overview

The AD-APARD32690-SL is a platform for prototyping intelligent, secure, and connected field devices. It has an Arduino Mega-compatible form factor and two Pmod-compatible connectors. The system includes the MAX32690 ARM Cortex-M4 with FPU-Based Microcontroller and Bluetooth LE 5.2. The MCU is coupled with external RAM (2 x 512 Mb) and Flash (64 Mb) memories to meet the requirements of the most demanding applications. The MAXQ1065 security coprocessor enables state of the art security features such as for root-of-trust, mutual authentication, data confidentiality and integrity, secure boot, and secure communications. A 10 Mbps single-pair Ethernet link using the ADIN1110 10BASE-T1L MAC/PHY, enables remote data acquisition and system configuration. The 10BASE-T1L interface also supports Single-pair Power over Ethernet (SPoE) and be used for powering the system via an Arduino shield implementing the required power circuitry.

The Zephyr port is running on the MAX32690 MCU.

Programming and Debugging

Flashing

The MAX32690 MCU can be flashed by connecting an external debug probe to the SWD port. SWD debug can be accessed through the Cortex 10-pin connector, P9. Logic levels are either 1.8V or 3.3V (based on P51 selection).

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. To perform a full erase, pass the --erase option when executing west 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 (P9) using an appropriate adapter board and cable.

Debugging

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