NXP FRDM-MCXW71

Overview

The FRDM-MCXW71 is a compact and scalable development board for rapid prototyping of the MCX W71 wireless MCU. It offers easy evaluation of the MCX W71’s multiprotocol wireless support for Bluetooth LE, Zigbee, Thread and Matter. The board includes an on-board MCU-Link debugger, industry standard headers for easy access to the MCU’s I/Os, an accelerometer, a light sensor and external SPI flash memory.

The MCX W71x family features a 96 MHz Arm® Cortex®-M33 core coupled with a multiprotocol radio subsystem supporting Matter, Thread, Zigbee and Bluetooth LE. The independent radio subsystem, with a dedicated core and memory, offloads the main CPU, preserving it for the primary application and allowing firmware updates to support future wireless standards.

Programming and Debugging

Build and flash applications as usual (see Building an Application and Run an Application for more details).

Configuring a Debug Probe

A debug probe is used for both flashing and debugging the board. This board is configured by default to use the MCU-Link CMSIS-DAP Onboard Debug Probe.

Configuring a Console

Connect a USB cable from your PC to J10, and use the serial terminal of your choice (minicom, putty, etc.) with the following settings:

  • Speed: 115200

  • Data: 8 bits

  • Parity: None

  • Stop bits: 1

Flashing

Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b frdm_mcxw71/mcxw716c samples/hello_world
west flash

Open a serial terminal, reset the board (press the RESET button), and you should see the following message in the terminal:

*** Booting Zephyr OS build v3.7.0-xxx-xxxx ***
Hello World! frdm_mcxw71/mcxw716c

Debugging

Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b frdm_mcxw71/mcxw716c samples/hello_world
west debug

Open a serial terminal, step through the application in your debugger, and you should see the following message in the terminal:

*** Booting Zephyr OS build v3.7.0-xxx-xxxx ***
Hello World! frdm_mcxw71/mcxw716c
