Well, the AT90S1200 is really a problem child... it requires a different startup procedure than all later AVRs. Anyway, avrdude is supposed to handle it, and I've successfully programmed them in the past. My first guess is that your programmer/computer is too fast to work reliably with the target controller. Try reducing the ISP clock by inserting delays, e. g. adding -i10 on the command-line. > I've also tried to read both the fuse bits and the lock bits, but it > returns the following in both cases: > read operation not supported for memory "lock" (fuse) ....which is simply due to the AT90S1200 not supporting these in ISP mode -- see the datasheet. -- cheers, J"org .-.-. --... ...-- -.. .
