Avrdude is not written to supply that signal. Instead of connecting the XTAL1 pin of the target chip to the parallel port, instead connect a seperate oscillator - crystal + caps or resonator, etc. After that, try again to enter programming mode. Also, if you utilize a chip with a built-in oscillator, the fuse bits should be set by default to use the internal 1 MHz setting in most cases, so in that case, the external oscillator is not necessary. Check your chip's datasheet to see if this applies in your situation. -Brian -- Brian Dean ATmega128 based MAVRIC controllers http://www.bdmicro.com/ _______________________________________________ AVR-chat mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/avr-chat
