I am using AS6.1 SP2, AVRONE debugger and XMEGA192A3U device.
The setup has worked fine but when I reasently received new hardware, LOT 3W2542, it start to not erase memory on some devices.
The errorcode is:
ModuleName: TCF (TCF command: Process:launch failed.)
An unknown emulator error occoured. Debugger command eraseDevice2 failed.
