Machinekit can also run with the 4.x preempt_rt kernel on the 'bone, but the PRU driver hasn't been updated for the re-arranged files in /sysfs so it won't work "out of the box". ...but there's a lot less coding to do to get a 4.x-rt kernel working than the latest Xenomai kernel. The Xenomai kernel will still have less IRQ latency and jitter, but the -rt kernels have gotten *DRAMATICALLY* better in this regard than when the 'Bone first came out (the "White" with no HDMI). Back then the Xenomai kernel was pretty much required for decent performance, but the Linux kernel on ARM has come a long way since then. -- Charles Steinkuehler char...@steinkuehler.net -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
