Hi Michael, I get the following configuration
fuse low byte 0xff fuse high byte 0xff fuse extended byte 0xff calibration byte 0xff - read only lock bits 0xff BLB12 -> 1 BLB11 -> 1 BLB02 -> 1 BLB01 -> 1 LB2 -> 1 LB1 -> 1 simply issuing the command >>uisp -dprog=data -dpart=ATmega128 --rd_fuses what did you mean by that?

whew...now I don't have to go look up the config bytes... Is there an internal osc that will run faster than the xtal? And are we certain that the config is really all 0xff? That sounds too conveniently like a read error... MS Giri Baleri wrote: > The low byte value of 0xff indicates that the ATmega128 is configured to > use external oscillator.
