Thanks for confirming it's not being overwritten by the bootloader code. It looks like you may be experiencing the issue described here: https://developer.arm.com/documentation/ka003046/latest/

Thank you for taking the time to follow my question. At the beginning, when I was debugging the DFU function, I set the same noinit section in both the app and BL. But it doesnt work. So I tried to just use SD+APP for debugging. The above process does not go through the bootloader.

Hello,

Have you made sure to place the same noinit section at the same address in your bootloader project as well? If not, it may be overwritten by the bootloader code on startup.

Best regards,
