Re: [Xenomai] Xenomai/cobalt: low_init(): binding failed: Function not implemented error issued when trting to run latency app on xeno 3.x-rc3

[Helder Daniel <hdaniel@ualg.pt>]

It seems that the Xenomai support was not loaded at boot time:

root@debian:/usr/src# dmesg | grep -i xeno
[    1.780077] [Xenomai] scheduling class idle registered.
[    1.780077] [Xenomai] scheduling class rt registered.
[    1.784077] [Xenomai] init failed, code -19
[   12.612754] *** RTnet for Xenomai v3.0-rc3 ***

I rebooted and now it seems it is loaded:

 dmesg | grep -i xeno
[    1.048963] [Xenomai] scheduling class idle registered.
[    1.048985] [Xenomai] scheduling class rt registered.
[    1.049211] I-pipe: head domain Xenomai registered.
[    1.070494] [Xenomai] Cobalt v3.0-rc3 (Exact Zero)
[    5.453304] *** RTnet for Xenomai v3.0-rc3 ***

But I still get the same compilation error.
I can compile and run a Xenomai user space app.

I am using a Cobalt setup, kernel 3.16, ipipe patch version
