I have it working Rick on . . . $ uname -a Linux beaglebone 4.1.9-bone-rt-r16 #1 Thu Oct 1 06:19:41 UTC 2015 armv7l GNU/Linux
This kernel was just an apt-get install. But, it's not a TI specific kernel if that's what you're wanting. As far as I can tell though, it's identical except that the pru stuff was re-enabled by Robert at our request some days ago. Couple weeks maybe ?
