Follow-up Comment #1, bug #18221 (project avrdude): It's always advisable to run the most recent firmware revision. Alas, that requires a machine running AVR Studio in order to upgrade the firmware.
Anyway, did you remember to set the ISP clock to a sane value? I've also seen AVRISP mkII devices that ship with a really sloooow default setting. As the setting is remembered in EEPROM, all it takes is to once connect using terminal mode, and issue a command like "sck 5". _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/bugs/?18221> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/ _______________________________________________ avrdude-dev mailing list avrdude-dev@nongnu.org http://lists.nongnu.org/mailman/listinfo/avrdude-dev
