Update 15 May 2014
I wrote a much more detailed version of this in the May 2014 article of Linux Journal. That article goes into more detail about the device tree, how to build the hardware on a proto-cape, and how to add a webserver frontend.
We now return you back to your originally scheduled programming.
This tutorial will explain how to program an ATmega328P (the microcontroller used in the Arduino Uno) from a BeagleBone Black (BBB). For those who can’t wait for the Arduino Tre, I’ll walk you through how to breadboard your ATmega328P to your BBB so you can be ready for its release! The motivation for this tutorial is that I’m looking to put an ATmega328P on my CryptoCape, since there are few crypto libraries written for 8-bit AVRs, namely NaCl.
