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.

Supported Features

The frdm_mcxw71 board target in Zephyr currently supports the following features:

Interface	Controller	Driver/Component
NVIC	on-chip	nested vector interrupt controller
SYSTICK	on-chip	systick
PINMUX	on-chip	pinctrl
GPIO	on-chip	gpio
LPUART	on-chip	serial port-polling; serial port-interrupt
FMU	on-chip	flash
TPM	on-chip	pwm
WDOG32	on-chip	watchdog
LPTMR	on-chip	counter

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.

Using J-Link

There are two options. The onboard debug circuit can be updated with Segger J-Link firmware by following the instructions in MCU-Link JLink Onboard Debug Probe. To be able to program the firmware, you need to put the board in DFU mode by shortening the jumper JP5. The second option is to attach a J-Link External Debug Probe to the 10-pin SWD connector (J12) of the board. For both options use the -r jlink option with west to use the jlink runner.

west flash -r jlink

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
