I'm having problems programming an ATXMEGA256A3U through PDI with an AVR Dragon. After much reading and debugging I found that my problem is with the VCC pin on PDI of Dragon. Sometimes I get the correct tension 3.3V but other I get values around 4V, which won't let me programm my xmega. Is there a way to force 3.3V on the AVR Dragon without breaking everything? Or is there any other solution I can use?
I can only program through PDI, the JTAG pins on the xmega are not available.
