Is there *current* and *correct* documentation about uBoot, uEnv.txt, capemgr, and CAN for the Beagle Bone Black? All of the hits I am getting doing web searches are for older pages, most of which do not work (or don't seem to work) with a current kernel (4.14.108-ti-r106). Or do I need a different kernel?
