That makes me think you're using AVRDUDE to program the device(s). What's your exact commandline then? I have successfully programmed boards with two chained AVRs in the past. Remember that each AVR shifts by four bits, so you need -X jtagchain=0,1,0,4 on one device, and -X jtagchain=1,0,4,0 on the other one. I didn't observe any specific clock issues, as when programming through JTAG, everything inside the AVR is clocked by the JTAG clock so it's independent of the main clock frequency. -- cheers, J"org .-.-. --... ...-- -.. .
