Stuff I've worked with have the flash chips programmed before PCB assembly, and yes, you can re-flash the chips including the "boot blocks" via software, possibly rendering the device useless. >The developers must have a way to reprogram dead units. > Not in the case above, unless you call harware guys with SMD rework equipment "Developers" ;-) Sometimes it is easier|cheaper to replace a whole PCB than to provide the ability to re-flash a chip on it. It is even done deliberately in some cases.
