Hi,

I have talked to Denis Carikli (GNUtoo) about this. He has implemented
the firmware for the Arduinos implementing serprog. IIRC you got an
Arduino Uno which uses a second avr chip instead of an FTDI to
connect the micorcontroller to the host. The standard firmware of
that chip does not cope well with high bandwidths, i.e. it is buggy.
Denis told me that reducing the baud rate supplied to serprog should
help with that problem in general, so I would suggest that you try that.

In the long term we want to provide a fixed firmware for the
communication Atmel processor. But he has no time and I am not too much
interested into fixing foreign code... I'd rather work on my own
serprog implementations :)

I will commit your patch (with my sign-off) soon, as it seems to be
fine. Thank you very much.
