I use Mega88 with Megabootloader.
With Avr-Osp II all works well.
Now I test Avrdude without a succes.
I try to read flash. I see no errors in Avrdude report,
but in the file read.hex there is only
I used command
avrdude -p m88 -c avr109 -P com4 -b 38400 -U flash:r:read.hex:i
I tried also avr911 instead of Avr109. The result is the same.
