    Bootload an ATmega328

    A big thanks for this post. I would note a couple of things: To edit the conf file you might need to go into preferences and security tab to give your self modify privileges. Secondly I found there were a couple avrdude.conf files in the maze of IDE download files. The one in ..Arduino/hardware/tools/avr/etc was the correct file to use. Now on to the next problem that I am pealing away like layers of an onion.Blink has less than 50% duty cycle even though on/off delays are equivalent in the sketch. : delay(1000);Probably related to the errors I got uploading the sketch:...avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x1cMaybe I have to do something different when loading the bootloader if I am using a 16 MHz crystal externally ? Here is to slow progress!
