What's the story here? Is it not possible to initialize EEPROM on Caterina?
@jediunix
Did you try modifying Arduino.mk and disabling the caterina check? This seems to have to do with a problem in older versions of avrdude. Anyway allowing eeprom hex upload works but avrdude will ask if the fuses should be updated. The modification is available on github.
Cheers!
