So I flashed the device with SAM-BA and accidentaly enabled lock bits. Next thing I know I got my USB wire disconnected from the board and after that SAM-BA doesn't recognize my board any more.

So where I stand it seems that the active locking bits are preventing the SAM-BA from connecting to the board. Is there any way to erase the whole flash memory or have I really bricked it for good?

I'm not experienced with AT91SAM family but I have done several things with AVR:s.

Thanks

edit: Oh and no, serial-connection doesn't work either. SAM-BA only gives me "No valid processor ID found"-error.
