I'm running AS6.2 and Atnel-ICE on Win7 Pro x64, targeting an ATTiny841 via debugWire. Everything was working fine yesterday (I could program and emulate), and I was careful to let AS6.2 terminate the session, but today when I try to connect to the target for programming or emulation I get the above error. The whole dialog is below. I get the same error if I swap an AVR-One or AVRISP MkII for the Atmel-ICE. I haven't tried connecting to another target yet. I've tried slowing the ISP clock down to 8 kHz, closing AS6.2, rebooting, but no dice. The Device Programming dialog can read the Target Voltage but nothing from the device proper like signature or fuses. Any suggestions?
