I am running at 16MHz.. divided by 4 that's 4 Mb/s, 400KB/s or so, and I get 2 KB/s at best (ie w/o the -B option, or with -B 0.15, the lowest value it will take before communication fails), that's 200 times less... > ...and for a bit clock of 0.15 it would need a clock at 27MHz (rounded up) or > faster. I tried 0.15 and it works fine at 16MHz... though actual speed is 2KB/s regardless. Anyway, the avrdude man page said this -B option in ISP mode, only works with the JTAG ICE only, not the Dragon so... -- Vince _______________________________________________ AVR-chat mailing list AVR-chat@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-chat
