For reasons I haven’t uncovered yet, I was unable to use the Arduino IDE to burn the bootloader to a fabbed Arduino board. For my first attempt at this, see the Fabkit / Fabduino post. Also see Ed Baafi’s Fabkit / Fabduino page for how to program an fabbed Arduino without an external clock through the Arduino IDE. In both OS X and Ubuntu I was unable to connect to the board through the IDE. Shawn Wallace suggested that I use the following code. (See “To Program Your Arduino” section below) The code below worked for me in Ubuntu. NOTE: This code below works for a using an external 8MHZ resonator, see the links to the .png files.

To Program Your Arduino:
Set the fuses with:
Paste code is all in one line
avrdude -c usbtiny -p m168 -B 5 -u -U lock:w:0x0F:m -U efuse:w:0x00:m -U hfuse:w:0xdd:m -U lfuse:w:0xf6:m -P usb
Burn the bootloader with:
Paste code is all in one line
avrdude -P usb -c usbtiny -p m168 -u -U flash:w:ATmegaBOOT_168_pro_8MHz.hex -U lock:w:0x0F:m -B .2
The options used:
- -u –> Disable safemode, default when running from a script.
- -U :r|w|v:[:format] –> Memory operation specification. Multiple -U options are allowed, each request is performed in the order specified.
