I'd like to enable the CANbus on a Beagle Bone Black (on Fedora ... which doesn't do "cape manager").
The crux is a fdt command in u-boot : fdt set d_can1 status okay Is there a way to do this in extlinux.conf ? I didn't see a way (in uboot 2017.09), so I wrote a uEnv.txt script (see attached). That's a bit verbose and duplicates a bunch of stuff already in uboot (also : uEnv.txt doesn't exist on my "Orange Pi One"). It there a simpler way to state "fdt" commands ? Thanks
