#1324 has been merged. It is a great addition to avrdude.

It will be good that the issues with older ATmega16/32/64/128(A) parts can be fixed in the future.

Have we established that other uploader/downloader programs can cope with these parts? If not the issue would be unconfirmed.

Yes, they are well supported by the other JTAG capable programmers, like JTAG1/2/3. I myself have tested them with JTAG ICE 1, AVR Dragon, SNAP and PICKit 4.

ATmega8 is not an ATmega in that respect: it doesn't have JTAG. Technically, it's a tiny device. Later variants (ATmega88 etc.) offer debugWIRE.

Good Point. I have updated the title and first post to remove ATmega8/8A.
