There are obviously xenomai kernels available. I have not tried to make an RT_PREEMPT kernel for the 'Bone for a while, but the OSADL guys have an am335x running with reasonable latencies using RT_PREEMPT: https://www.osadl.org/Profile-of-system-in-rack-7-slot-5.qa-profile-r7s5.0.html It's not running on a BeagleBone, but it's the same SoC. It's a 3.2 kernel and not 3.8, plus the latency is about 1.5-2x what I see with Xenomai, so I haven't really been anxious to try it out. ...but it is good to have both flavors available on the ARM, and steady progress being made on the RT_PREEMPT code. -- Charles Steinkuehler [email protected]
