Assuming the EPROM has already been loaded with a new binary image, is it possible to flash a PIC with the image in EPROM completely stand-alone?
Specifically what I want to do is send the PIC a new image via IrDA which it will store in EPROM. After checksum verification it will then reflash itself with that image.
It is acceptable to assume the self-flash routine would not be upgradable via this technique. IE that chunk of memory would be identical to the corresponding part in the new image.
