latency-test in LinuxCNC based on ARM(BBB) was created by shameless
Hello!I want to run LinuxCNC on ARM system.
I compiled the Linux kernel (version:3.8.13) and xenomai (version:2.6.3) real-time kernel on X86 system, and successfully ported to ARM .There is not any problem when I test the real-time performance of xenomai ( Latency) .
But the latency-test value in LinuxCNC is too large (1ms) and shows" Using POSIX non-realtime". When installing linuxcnc, configure in the debian directory will also show "your kernel xenomai is not known". what‘s wrong？

If you want to run on BBB then it might be simplest to use the pre-made images from the Machinekit project.
