Hi, I just find out the solution. It was because of your kernel version you have to update to the 4.1.21-bone-rt-r20 More detail on my last 2 post : https://groups.google.com/forum/#!searchin/beagleboard/PRU|sort:date/beagleboard/5gD73Jm_Xss/4omwOtw3BQAJ
sudo apt-get update sudo apt-get install linux-image-4.1.21-bone-rt-r20 sudo reboot That should work. At least I hope so ;-) Enjoy !
