MCXW71 is a three-core platform that integrates a Cortex-M33 application core (CM33), a dedicated Cortex-M3 radio core, and an isolated EdgeLock Secure Enclave. The radio core, also called as Narrow Band Unit (NBU) features a Bluetooth Low Energy (LE) unit with a dedicated flash. The memories integrated in the NBU consist of Bluetooth LE controller stack and radio drivers. On MCXW71, 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.
