Hello Renesas Engineering Community,
My company has developed a device using R5F5631A microcontroller for a project. The device FW is implemented with ID code protection feature.
Now a situation has come that we need to upgrade the FW. Unfortunately we lost IDs for some earlier batch of devices. Is there a way out for this problem to be solved so that we can retrieve the MCUs, of which we lost the ID code??
Hello Hashidha K,
It's possible that you will need to replace the MCUs. It depends on the control code value for the ID code you set before. Try to erase the MCU in the boot mode. For more details please refer to this knowledge base article: https://en-support.renesas.com/knowledgeBase/16979097
