An article that I wrote about the #Capemgr and #devicetree of the #beagleboneblack will be appearing in the newest issue of Raspberry Pi Geek magazine. The article explains what the device tree data structure is, how device tree overlay loading is handled via the Capemgr, and which P8/P9 pins are in use by default on the BBB. The PDF version is available now, and the print version will be hitting the newsstands in a few weeks.
Irony all the things
