First post to this list, so my apologies if I've broken etiquette by
posting like this. I'm the author of a patch to the BusPirate which gives
it a new mode to verify the flash on an AVR at a much higher speed. This
patch has been incorporated into the 6.0 firmware for the BusPirate, but
the component that is required in AVRDUDE to make it work is not included
in the official AVRDUDE release. As such, I'd like to make you aware of it.
