I have implemented Giorgos' Butterfly-type bootloader on a m162
system. It seems to function perfectly when operated from
Avrprog with my target "posing" as a m169.
Now I would like to use Avrdude, but It it does not seem to work. It
goes through the motions, but seems to load the flash with a block
of zeros, which of course leads to a verify error.
Is anyone actually doing this sucessfully? I did a search and could not
see where someone has specifically done this.
