Follow-up Comment #10, bug #27254 (project avrdude):

Hi Klaus

I will try different clock speeds and see what happens.

When I drop to below 57600bps, then all works fine with AVRDUDE.
At 57600bps problems start and I get failures around 80% of the time.
At 115200 no programming can be done.
The CPU clock is 2MHz. I will try 32MHz and see if there is a difference.

One thing to note is that I am using the App note AVR1605 which is supposed
to be the same as AVR911 but ported to work for the XMega. I wonder if there
were problems with the porting from AVR911 to AVR1605. I will check it out and
provide feedback as well.

Best regards
Priyend
