[avrdude-dev] jtagice mkI and atmega644

[Andrew S]

After doing some research and getting varying information I'm hoping someone 
on this list can give me a good answer to this question. I am having problems 
programing an Atmega644 using a jtagice mki clone (Olimex), and I wanted to 
confirm that this solution does not work? (In specific, avrdude fails 
verification because the entire flash is read back as 0x00)

Can someone explain to me why the devices cannot be programmed with these 
programmers? I can't find a clear explanation of the differences between the 
MKI and MKII programmers online, other than the mkII contains support for a 
debugwire interface, which is not an issue for this chip.
