See this comment in AVaRICEs source code: // 'S ' works if this is the first string sent after power up. // But if another char is sent, the JTAG seems to go in to some // internal mode. 'SE ' takes it out of there, apparently (sometimes // 'E ' is enough, but not always...) sendJtagCommand((uchar *)"SE ", 4, &tries); I've added something similar to the sync logic in avrdude now. I hope that gets you running as well. I can definately see differences on my clone after a powerup, too, although the effect was not fatal here but I've got the wrong response to the hard/software version inquiry. This is gone now with the changed code, so I hope it'll also fix your problems. -- cheers, J"org .-.-. --... ...-- -.. .
