Arrow BBB's support is only in v4.1.x+, since it uses an ADI framer vs the
NXP one on the BBB, "I" didn't care enough to backport the ADI driver to
3.8.13...  Thus you get ^ message..

You can force:

dtb=am335x-boneblack.dtb

in /boot/uEnv.txt just make sure to disable hdmi...
capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN
