Hoping i could get some help.
I'm using AVR Dragon with AVR studio and an ATTiny12L-4PC microprocessor.
My first problem was that I couldn't enter programming mode in PP/HVSP mode. All the lights on the dragon would go out and i'd have to disconnect and reconnect power to get it to even try again.
Giving up on that i switched over to ISP mode. It worked fine for a while, (erasing, writing, reading, etc. ) but then when i changed some of the fuse settings it stopped entering programming mode. I tried a different ATTiny12 and it still didn't work. All it will do is write and read the ISP frequency. It won't read the signature or fuses or anything. I've tried rebooting, i've redone the wiring on the dragon, i've tried different ISP frequencies, i even did the firmware update again.
Is it possible i damaged the dragon by changing fuse settings or is something else the problem here? I didn't ignore any of AVR studio's "smart warnings" when i changed the fuse settings, so i didn't think i could have messed it up too bad.
Anything else i can try?
Thanks,
Kyle
