On Windows I have used arduino Java IDE. Arduino IDE distribution
actually includes a whole WinAVR stack including avrdude.exe,
but I didn't pay attention what is actually used.
I will reboot to Windows now and check the commandline invocation.

On FreeBSD arduino the Java IDE tries to use avrdude and fails the same
was as from commandline.

AVRDUDE is mentioned for example here http://www.arduino.cc/playground/FreeBSD/CLI
as the tool to use.

I have tried "-c arduino" or "-c stk500v1" with trunk and I get still
the same affect as with 5.10 (Programmer timeout).

What maybe important: TX/RX LED on the board don't react at all
when trying to use avrdude (there is only a single blink
on firmware LED - which means bootloader start).

With Windows - TX/RX indicated clearly some activity.

Hm, yes, sorry... You were copied on the original send-pr.
