I just upgraded another Dragon to 7.38 (decimal), and it works without troubles using AVaRICE (SVN version) on my ATxmega16D4 board. > I attempted to use the Dragon to connect to 2 different XMEGA devices, one > is a custom PCB I made with an xmega16d4, the other is a development board > with an xmega128d4 using AVR Studio 7 in programming mode.

The target voltage is sensed on the Dragon itself, without the need for a working PDI link. This error code 0xAE is likely an indication for PDI link issues - but still, you might ask Atmel explicitly about that. While the JTAGICEmkII protocol is officially documented in an appnote, the Xmega protocol isn't. How long's your cable? The levelshifters/drivers on the Dragon are known to be fairly weak. In general, the cables that come with an STK500 work well, they are about 15 cm long. Anything longer might cause troubles. -- cheers, Joerg .-.-. --... ...-- -.. .
