Had anyone out there change a lower flash xmega to higher flash xmega without encounter any bug?
I had been using ATXmega64A3U. I had plan to put in more flexable data in to the EEPROM, but the ATxmega64A3U EEPROM too small.
So I change the chip to ATXmega256A3U. As my flash firmware still the same, but increase in the EEPROM only.
I had encounter problem using my old firmware which complie using ATxmega64A3U. From my understanding this should not happen as normally it can be upgraded, that the frimware should be able to run in the higher flash.
