MC with reflashed signature

[anifontov11]

Hello, folks! Need some help!

 

Is it possible by the means of AVERDUDE to read the complete image of the MC (FLASH, EPROM, fuses, signatures, etc.) into one file that could be flashed into a new chip? (including signature bytes) The main problem is that signature bytes of the original chip were changed and it is necessary to use -F option.

Does AVERDUDE know how to alter signature bytes? If not, how to do it?

 

So far I have unsatisfactory result:

program enable instruction not defined for part "ATxmega32D4"

avrdude.exe: AVR device not responding

avrdude.exe: initialization failed, rc = -1

avrdude.exe: AVR device initialized and ready to accept instructions

avrdude.exe: Device signature = 0x987ba0

avrdude.exe: Expected signature for ATxmega32D4 is 1E 95 42

avrdude.exe done. Thank you.

 

So the program understands that there was a command to ignore the signature mismatch, but still does not go further.

It would be nice to have the correct command syntax (including where to insert "-F") from the experts..

 

Thanks, Alex
