Re: [avr-chat] How can I individualise specific CPUs?

[Juergen Harms]

Thank you, nice to have code just to copy from.

That brings up a second question: are there any guidelines how paranoiac 
to be with checksumming of data in eeprom?

Reread-verify after download is an evident necessity - one extreme; I 
certainly will not checksum what I write to RAM, the other extreme. 
Between these extremes, where situate EEPROM writes? The reply is 
certainly hardware/manufacturer specific - how reliable are writes to 
internal eeprom of an Atmel processor?
