That's annoying... because if my fuse bits are correct, and it's not the crystals or capacitors, then I can't see what it could be, and therefire have little hope to get it working :-/ > I've mentioned this before, but if you just pin-out the > JTAG port and use a JTAG programmer you can mess with fuses to your heart's > content because the JTAG port has its own clock and works fine when the main > clock is screwed up. *And* you get on-chip debug, which might help Vincent > with some of his problems. IIRC, the latest and shiniest release of Avrdude does support JTAG programming ? Does it also work with a cheap/DIY cable like SPI programming ?? As for in-system debugging, hell, that's my dream, setting breakpoints, step by step execution, watching variables in RAM, stopping execution when some event affects a variable in RAM, how beautiful. But, forgive my ignorance (I only know of avrdude), are there mature and usefully functional/featured open-source software that can do that ? Do they have a decently user friendly interface for setting break points and watching data/variables in RAM, and controlling and visualising code execution ? And can they work with a hand made/DIY cable, or do they require expensive extra hardware ? Do they come with decent documentation to get people started ?
