Thanks for your advice Markus, I have solved the problem. I had a very unpleasant hardware fault on my STK500. Quite why it appeared to work under AVR studioa nd not under AVRDUDE is still a mystery - but that's life. Although I bought it new, from a reputable shop, once I started really looking closely I noticed that it had been soldered in some places. The high voltage generator had all 4 transistors blown, so I had to replace them. Allworks fine with AVRDUDE now.
Robert EDIT: I have never even touched the HV programmer, but from the Invalid device signature i got the idea, that this might help. 2009/11/10 markus järve <[email protected] <mailto:[email protected]>> looks like problem i had with AVRISP2. What i did was to change SCK on avrdude. $ sudo avrdude -c avrispmkII -P usb -p m88 -F -u -t i did set it on 4 and it started to work like charm. Maybe usefull Cmc _______________________________________________ AVR-chat mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/avr-chat
