So, I have been working on by BBB and loving it. I wrote my first device tree overlays and I’m getting more familiar with the way recent Linux kernels handle hardware peripherals. Very powerful, pretty intimidating too.
My question to the community is: what are the best sources of information on how to learn how to use the Beaglebone’s hardware? http://hipstercircuits.com/ is an absolutely great resource, and http://gigamegablog.com/ is too. Then there is http://www.devicetree.org/ too, of course. But what are your preferred learning sources if you really want to become a BBB ninja?
