Goal of this lab is to show the SDK example implementing the wireless UART profile and we will move forward in making some meaningful modifications to the example itself with the goal to show where in the code the end user should enter the relevant application software for the application. Run Wireless UART IoT Toolbox Demo

The MCX W72 family features a 96 MHz Arm® Cortex®-M33 core coupled with a multiprotocol radio subsystem also called Narrow Band Unit (NBU) 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. On MCXW72, only boot ROM has access to the NBU flash. The ROM bootloader provides an in-system programming (ISP) utility that operates over a serial connection on the microcontroller units (MCUs) The objective in this hands-on, is to learn how to recognize when the NBU firmware does not match with the SDK version.

In this lab we make some experience with the FRDM-MCXW72 board using the SDK project to implement a simple LED blinking. Once we will get familiar with the example project, we will integrate simple modifications

In this lab we will first import the MCUXpresso SDK for the MCX W72 Freedom board into MCUXpresso IDE and then we will build, flash and debug the hello world project to make sure the environment is set for the following Labs  

Introduction This document is intended to guide you in the installation of the tools and let you know the material required for the FRDM-MCXW72 Hands On.  Required Materials The material and the software requirements will depend on the hand on, but the next is what it is required in most of them. Hardware Requirements FRDM-MCXW72 Board Personal Computer Type C USB Cable Software Requirements IDE: Visual Studio Code 1.107.1 or later SDK: v25.12.00 MCUXpresso extension for VS Code version v25.12.48 BLHost Tool or LinkFlash tool (Linkflash is included with LinkServer installation) Windows OS (It was used Windows 11 for this hands-on) NXP IoT Toolbox (For an Android or iOS device) Serial Terminal program, like PuTTY or Tera Term Environment Setup Note: In order to make downloads in NXP website, it is necessary to have an account. Register and log-in for moving forward. MCUXpresso for Visual Studio Code                                                                                                                                                                         MCUXpresso for Visual Studio Code (VS Code) provides an optimized embedded developer experience for code editing and development. The extension enables NXP developers to use one of the most popular embedded editor tools and provides an easy and fast way to create, build and debug applications based on MCUXpresso SDK or Zephyr projects.   Install it following the next steps: Download Visual Studio Code from Microsoft Store or visual studio code web page Download Visual Studio Code - Mac, Linux, Windows Access to vscode for MCUX wiki and download MCUXpresso Installer  Dependency Installation · nxp-mcuxpresso/vscode-for-mcux Wiki · GitHub Run MCUXpresso Installer and for MCXW72 Hands On install at least MCUXpresso SDK Developer Matter Developer Arm GNU Toolchain Standalone Toolchain Add ons Linkserver PEmicro Installing the FRDM-MCXW72 SDK V25.12.00   Each MCU has its own SDK that includes driver, examples, middleware, docs and other components. To get and build the demo, let’s install the SDK into VS Code. Install the NXP’s GitHub SDK: Once MCUXpresso for Visual Studio Code is installed, open VS Code. Go to MCUXpresso for VS Code extension that is on the tools column at the left.    Look for INSTALLED REPOSITORIES option and press ‘+’ (Detail steps are described in wiki page. Working with MCUXpresso SDK · nxp-mcuxpresso/vscode-for-mcux Wiki · GitHub).                                               Search for the remote option of the Import Repository window. Select the MCUXpresso SDK in the repository option to download the GitHub SDK, then in the Revision tab you can select either the “main” revision (which corresponds to the latest version available) or to select an specific version (we’ll be using version v25.12.00 for these series of labs), optionally you can change the repository name and location.     Finally click on the “Import” button. Blhost Installation The blhost application is used on a host computer to issue commands to an NXP platform running an implementation of the MCU bootloader. The blhost application with the MCU bootloader, allows a user to program a firmware application onto the MCU device without a programming tool. Please go an download the tool in the next path and make sure to placed in a known location. BLHost Download page.

This MCXW72 training video talk about the Lifecycle state model, explain in detail the purpose, and security recommendations for each state.  Training shows the fuses involved in this process to advance lifecycle and enable the basic security features like Secure Boot and Secure Debug. Video also includes examples about how to use MCUXpresso Secure Provisioning Tool (SEC) to create Root of Trust Key Hash (RoTKTH) and SB3KDK Encryption key as well as hoe to active debug authentication before to move Lifecycle states.
