I'm trying to use my Arduino UNO R2 (Auto reset disabled) as a Programmer with the circuit used here:

But when i use optiloader it works fine.
(And i am sure that the auto reset is disabled for good)

Here avrdude's output in verbose mode: http://pastebin.com/raw.php?i=jXG8agN9

Any idea what could be wrong?

Please help me getting rid of that old xp pc in my cellar i keep just for that (damn slow) parallel programmer :slight_smile:
Thanks!

I had this issue when I was using Arduino version 1.0. Arduino 0023 worked for me.

Yes, there is a problem with Arduino 1.0. You may also need to put a 200 ohm resistor as strong pullup between RESET and +5V on the Uno.
