Basics Of Boot Sequence

I like boring legal documents..there is a lot of good info in there..well found..

Thinking between the lines..There seem to be a few small chinks in the security, but I haven't got the resources to follow them up..maybe somebody else has..

The algorithms are used to create the hash from the code and then it is checked against the expected result..which . if the numbers don't match shuts everything down..obviously sets an error flag calling a sub-routine..now I would need the full bootloader and kernel but just maybe it is possible to hijack the error flag sub-routine to load any code we want, thereby totally side stepping the reboot/reset code??

just thinking out loud.. huh.gif
