Does not your JTAG dongle come with a driver and stuff? – Martin James May 14 '14 at 18:37

yes you need to use one of those. I dont think spi works on an xmega, its serial interface is more painful than other avrs but still doable. It is all documented in the avr documentation on how to do it yourself if you have some other thing you can bit bang with, I think I used a $5 msp430 launchpad (was a sale price now at $10) plus software I wrote. prolly easier to just buy an inexpensive isp cable/box/board that supports xmega. – old_timer May 14 '14 at 20:14
