NXP FRDM_RW612
Overview
The RW612 is a highly integrated, low-power tri-radio wireless MCU with an integrated 260 MHz ARM Cortex-M33 MCU and Wi-Fi 6 + Bluetooth Low Energy (LE) 5.3 / 802.15.4 radios designed for a broad array of applications, including connected smart home devices, gaming controllers, enterprise and industrial automation, smart accessories and smart energy.
The RW612 MCU subsystem includes 1.2 MB of on-chip SRAM and a high-bandwidth Quad SPI interface with an on-the-fly decryption engine for securely accessing off-chip XIP flash.
The advanced design of the RW612 delivers tight integration, low power and highly secure operation in a space- and cost-efficient wireless MCU requiring only a single 3.3 V power supply.

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 JLink Firmware.
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. This example uses the J-Link Debug Host Tools as default.
# From the root of the zephyr repository
west build -b frdm_rw612 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 v3.6.0 *****
Hello World! frdm_rw612
Debugging
Here is an example for the Hello World application. This example uses the J-Link Debug Host Tools as default.
# From the root of the zephyr repository
west build -b frdm_rw612 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 zephyr-v3.6.0 *****
Hello World! frdm_rw612
