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) This hands-on describes how to update the code in NBU and the User firmware using the ISP. Lab guide: FRDM-MCXW71_NBU_and_User_Firmware_Update_Using_ISP

Unlike MCXW 71 MCU, MCXW 72 supports an Open NBU. This means that NBU firmware source code is exposed to user. On MCXW 71 MCU, NBU firmware is NXP proprietary; it is not user customizable.
