This document is intended to guide you in the installation of the necessary tools and repository for start running Zephyr examples and development. Zephyr is a lightweight, open-source real-time operating system (RTOS) designed specifically for microcontrollers (MCUs) and other resource-constrained embedded devices. Unlike general-purpose operating systems, Zephyr is built to run on systems with limited memory, low power consumption, and strict real-time requirements. It provides the core software foundation that allows an MCU to run multiple tasks reliably, respond to events on time, and interact with hardware in a structured way.

This document is intended to guide you in the installation of the necessary tools and repository for start running matter examples and development. Matter (previously known as Project CHIP) is a single, unified, application-layer connectivity standard designed to enable developers to connect and build reliable, secure IoT ecosystems and increase compatibility among Smart Home and Building devices. Backed by major brands and developed through collaboration within the Connectivity Standards Alliance (previously known as the Zigbee Alliance), Matter is an open-source royalty-free connectivity standard built with market-proven technologies using Internet Protocol (IP) and compatible with Thread and Wi-Fi network transports. Building solutions and leading standards efforts, NXP provides scalable, flexible and secure platforms for the variety of use cases Matter addresses – from end nodes to gateways – so device manufacturers can focus on their product innovation. NXP’s Matter solutions go beyond just the connectivity with comprehensive capabilities for the compute and security requirements for IoT devices.

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.
