Hi,

I got an old mightyboard that was a bit broken, repaired it and replaced the Atmega1280 cpu with a larger Atmega2560 as some sailfish features are suposedly only available for this one.
Now i did not found any instruction how to firmware on properly.
I got a boot loader installed and I can upload Atmega2560firmwares form replicator G but non is specifyed to be the right one for the CTC printer.
So which one should I take? Also what stuff do I need to put into the EEPROM, as its a new chip its obviously empty.

Any advice would be greatly appreciated.
