Hello,
Thanks for reply.
I made the manual changes in  version 2011.08 of buildroot and work fine.
Now I start the linux with qemu and it is ok. But when I try use the
usr/xenomai/bin/xenomai-test it get the following error. Do you know this
error? How I know if Adeos and Xenomai are installed correctly? My
aplication is for ARM and I have few aplications.
Best Regards,
Adriano Campos

Looks like your kernel configuration is wrong and does not have Xenomai
enabled, or some other Xenomai options needed to
have /proc/xenomai/latency available.
