I used the info from a post you made in this thread: https://groups.google.com/forum/m/#!category-topic/beagleboard/software/tdt1TTix7aE
It's your 3rd post from the top, sorry, couldn't figure out how to link to it. I started from the Jessie BBB image that had the 4.1.15-ti-rt-r43 kernel. Now I have the 4.4.2-bone-rt-r5 kernel that I compiled and installed myself, am I maybe missing some udev rules?
