XOrduino/bootloader

The bootloader can be installed using another Arduino

sudo yum install arduino

you are then given the option of upgrading to version 1.0.1, note where you save to (in my case /home/olpc/arduino-1.0.1/)

$ su
bash-4.1# /home/olpc/arduino-1.0.1/arduino

The programming technique is described at [1] but the pins are different, see the diagrams below

• Load arduinoISP from the examples
• Tools/board to match the Arduino being used as a programmer
• Upload
• Tools/board Leonardo (the XOrduino)
• Tools/Programmer Arduino as ISP
• Tools/Burn bootloader
