[avr-chat] xmega lock bits vs avrdude

[David Martin]

I cannot program the lock bits on an XMEGA128, via avrdude.
I found this bug: http://savannah.nongnu.org/bugs/?30451
But it does not seem to have any tracking, over a year old.

Is there a way to program the lockbits, without Studio?  I am at a loss.
