Abstract

This application note describes the live firmware update algorithm using bank swap and a CSC (Customer Secure Code), and explains how to implement it on MSPM0 devices that support dual-bank memory. In this example, the LP-MSPM0G3519 EVM is used, and the new firmware image is transmitted via UART communication.
