Hello,

I am attempting to run Xenomai 3.0.5 on an embedded system.

It is being built using Buildroot 2017.02.2, Xenomai 3.0.5, Kernel 4.1.18,
Adeos patch 4.1.18 #9.

The resultant image boots, and I can see that Xenomai is running:


*dmesg | grep -i xeno*
[    1.233003] [Xenomai] scheduling class idle registered.
[    1.233098] [Xenomai] scheduling class rt registered.
[    1.233373] I-pipe: head domain Xenomai registered.
[    1.236591] [Xenomai] Cobalt v3.0.5 (Sisyphus's Boulder)
[    2.208662] udevd[664]: specified group 'xenomai' unknown

But attempting to run ANY of the test apps for Xenomai segfaults:

(Sorry about the length)

Any ideas on where i could start looking about?  I don't see any causality
here...

Thanks,
