avrdude hang when uploading

Hello guys,

I could reproduce a bug probably in avrdude.

Steps :

Get an arduino MEGA 2560 Get Arduino IDE Get Repetier firmware with your parameters, but EEPROM_MODE 1 Upload : after 4 #, the upload hangs

Windows is messed up : zombie avrdude locks the COM port.

Edit configuration.h : EEPROM_MODE 0

Upload again : it's OK.

This happens in both Windows and Linux.

I spent 2 days on this one !

Seb
