Worried about OTA Failure Bricking Your Device? Boot Swap Can Help You

This section mainly explains how to use the existing program to update the firmware in the flash. Using this method, the code flash is divided into two areas: the execution area and the temporary area. The Renesas Flash Driver RL78RFD Type02 is used to reprogram the flash and perform boot swapping. This explanation mainly takes RL78/F24 as an example to explain how to implement boot swapping.
