Missing Bootloader

If the bootloader is missing, then simply go to the download page, download the bootloader package, and program the bootloader in yourself. There's no simpler way. Make sure you use the right bootloader build and fuses (ATmega328P running at 12 MHz, use the 4K bootloader setting and the corresponding fuses, unless your setup is custom).

Crystal Casing Too Close to Pads

This has been fixed in PCBs made since May 2011.

The 12 MHz crystal's casing is made fo metal, and it is very close to the oval shaped pads that for the ATmega's chip socket. The distance between the pads and the crystal is enough for them not to actually contact, but it may seem scary close. If you have any problems, check to see if they actually do touch. If you are paranoid, place a thin sheet of plastic under the crystal while soldering it in place.

AVRDUDE Problems on Linux

Make sure you have enough permissions to use USB devices if you are on Linux, or else AVRDUDE may report "error sending control message: Operation not permitted". One way to solve this is to use "sudo". Another way to solve this is to make a file named "avrdude-usbasp.rules" in "/etc/udev/rules.d/" containing the line:

SUBSYSTEM=="usb", SYSFS{idVendor}=="16c0", SYSFS{idProduct}=="05dc", GROUP="adm", MODE="0666"

and then Restart udev with "sudo restart udev"
