Recently I have installed AVR Studio 6.2 instead AVR Studio 6.1. And my two ATmega256RFR2 xplained pro kits demanded updates. First of them has updated without any problem. But with second kit is big problem: during update it asked reset it and after that it is no longer updated. Now AVR Studio is not see this kit. Moreover, Windows sees it only as hid device.
AT32UC3A4256J-C1UR is used as programmer in this board. But my attempts to find the original hex-file failed. Of course this kit can be used with an external programmer. But is there a way to restore the debugger on the board?
I would appreciate any help.
