2023-04-25
●Overview
■Purpose: This application note describes the operation of the System Bootloader sample code on the RSK platform with a view to aiding development of similar applications. In addition, this application note uses “RX Family Flash Module Using Firmware Integration Technology (FIT)”.
■Features
▲The System Bootloader sample code demonstrates the ability to update application code in the internal flash memory of RX140 via SCI while the system is running, using a standard S-Record or hex programmer file format. It incorporates system integrity checking facilities such as CRC Flash memory verification and a watchdog.
▲The RSK board contains all the circuitry required for microcontroller operation.
●Introduction: This application note is designed to illustrate how the System Bootloader sample code provides the ability to update application code located in on-board Flash memory on the MCU whilst running, via a serial connection from a PC or equivalent device.
