I have created a simple devboard for the XMEGA A4 series micros, I program the board using the AVR DRAGON programmer (PDI interface).
First I tried the XMEGA32A4, it worked without a problem, but now I soldered on an XMEGA128A4U and it doesn't work, I can't get it to program. I tried on multiple boards, so i is fairly unlikely that the part got damaged while soldering.
The Target Voltage reads 3.2V, but when I try to read the Device signature I get the following message:
Got error setting up PDI mode: Device is not supported in this emulator mode. Debugger command setParameter failed. Unable to enter programming mode. Verify device selection, interface settings, target power, security bit, and connections to the target device.
I attached a screenshot for more details and I also attached the schematic for my devboard!
The XMEGA parts are from a reliable source (Mouser.com) so that shouldn't be an issue... I read that the many have problem with the AVR Dragon programmer, but it worked fine for me (I'm running Atmel Studio 7.0 in a Windows 7 virtual machine). What should I try next? How can I get the boards working? Should I try to get a hold of a different programmer?
