Burn the Arduino bootloader using RPI

[trevorford]

I've been looking online but haven't found anything promising,
I'm building a few Arduinos and I need an easy way to burn to bootloader to them, I know i can just buy a programmer but I would rather get the job done with what I have. I'm curious to know if there is a way to do this with just my Raspberry Pi
If anyone knows or has a link to a good tutorial that would be great.
Thanks,
Trevor

Do you have one already boot loaded Arduino? I used my original uno to boot load an Atmega chip I bought from Digikey.

I dont have one personally but one of the teachers at my school does so i might be able to use that! thank you.

There are a couple of Arduino sketches that will burn bootloaders onto other arduinos very quickly.
I was first with "Optiloader": https://github.com/WestfW/OptiLoader and it's probably simplest (but harder to upgrade, and not so well documented.)  Also, it's designed for very fast bootloader programming: connect a cable from the arduino with the sketch to the target arduino, hit reset, and wait for the target power to cycle...

Adafruit followed with their standalone programmer: https://github.com/adafruit/Standalone-Arduino-AVR-ISP-programmer which is more general purpose and less bootloader oriented.

And the most recent is Nick Gammon's "Chip Programmer" here: http://www.gammon.com.au/breadboard (this one is probably the best-documented, especially WRT burning bootloaders.)

AVR programming is via SPI, with no inconvenient high voltages, and RPi theoretically supports SPI as well, so in theory you could write a quick programmer for RPI as well.  Or apparently avrdude will run on RPi: http://kevincuzner.com/2013/05/27/raspberry-pi-as-an-avr-programmer/
(beware voltage levels, though!)
