Chip appears working, it still "runs", but I can't upload anything else, the error is
avrdude: verification error, first mismatch at byte 0x0002
0x5b != 0x5c
avrdude: verification error; content mismatch
I then used my AVR programmer, and got
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.
It's fried, right?
