Hi,

i wonder if it is possible to replace a bootloader in an ATMega128
with a new version.

Is this possible in a secure way so that a power failure or communication
failure does not leave the system in an inconsistent state?  So to say that
it is possible to re-start the re-programming again after a failure?

What design options need to be considered to do this?


Best regards,
Torsten.
