Kernel Hacking on the Beagle Bone

Over on Hipstercircuits they have a nice writeup on adding BeagleBone cape support to a kernel with device tree in Ubuntu.

[ 1.822762] bone-capemgr bone_capemgr.7: slot #1: Requesting firmware ‘cape-bone-replicape-00A1.dtbo’ for board-name ‘Replicape 3D printer cape’, version ’00A1′

Am I dreaming? After visiting every inch of the kernel twice, it’s hard to believe that I have finally cracked it. With my face still stuck on the keyboard, I manage to scroll up in the boot log to get a better look. Yes, it is true! My firmware has been loaded into Device Tree! Do you know what this means? The SPI device is available! That means the Replicape is working on Ubuntu! That means that everyone will buy Replicape for their printers and I will finally have world domination! Anyways, that’s it for the fun part, now let the geeks work : )

Pick up a BeagleBone in the Adafruit shop and start hacking!
