I just got my first xmega32a4 chips in a tqfp44 package and would like to play with them. My PCB will take some weeks to get ready so I want to solder a couple of wires to a chip to play and have some questions:
1) Do I have to connect all Gnd/Vcc pins or a single pair will do ?
2) Programming is using PDI, so connecting reset, PDI, Gnd and Vcc is sufficient ?
3) I'm using dragon (original version) and want to use avrdude on Linux. Will that work ? Will I need specific dragon firmware ? If yes, which one ?
