Ok, I have now more info:The signature corresponds to the MEGA16U2, so I am connected to the wrong chip.Any ideas?
The 1284 shouldn't have major size issues; it has 64kwords of flash, and most of the serious difficulties happen when you go beyond 64k (note that 64k words == 128kbytes.)
I don't believe the USBASP based on Atmega8 will program the full address range of the '1284.
