If the fuses are in the factory default state, then SCK is too fast. The mega168 is running at 1MHz (8 MHz internal osc with 1/8 prescaler). SCK frequency needs to be less than or equal to one quarter of the system clock. Try setting SCK period to 4.4 us. galen _______________________________________________ avrdude-dev mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/avrdude-dev
