I have written bootloaders for which that was not the case. I admit I haven't read very much literature on this, but it is seems to me there always be at least one moment when the chain is vulnerable. This is because the boot process is like a chain, to me, and what you're trying to do is to change one of its rings by erasing and reprogramming a memory sector. If the MCU is stopped after or during the erasing process and before the programming finishes, everything goes up in smoke. Anyway, would you share your idea? |
