Device Tree Overlay for BB
How to setup device tree overlay : If this works (as root), everything is great:
cd /lib/firmware echo cape-universaln > /sys/devices/bone_capemgr.*/slots
However, an old version of universaln has a conflict with the HDMI/audio port P9.31
The updated version, should be included in this package as
cape-universallc-00A0.dts can be used instead:
cp cape-universallc-00A0.dts /lib/firmware cd /lib/firmware dtc -O dtb -o cape-universallc-00A0.dtbo -b 0 -@ cape-universallc-00A0.dts echo cape-universallc > /sys/devices/bone_capemgr.*/slots
cape-universallc has the lines corresponding to P9.31 commented out.

dmesg | less.
To test if everything is expored coorectly, run (in julia, as root)
