Xmega ‘noob here.
I have an atxmega256A3AU part on a board running at 3.3V with a 12Mhz crystal. My Atmel studio is version 6.2.1502, service pack1. I am using a MKII programmer, had the part set to atxmega256A3U and I set the BODLVL to 3V0 in the “device programming” mode. Once I did that, I lost communication to the processor. The crystal is no longer oscillating.
I think where I messed up is that I had should have set the device programming to atxmega256A3 for this part. (not atxmega256A3U) The atxmega256A3 does not have a fuse setting for 3V0. (it has a 2V9 and 3V2) Since this is my second time doing this, I really don’t want to replace the IC on the board again. Is there a way for me to resume communication with the atxmega part?
