[Xenomai] Xenomai: binding failed: Operation not permitted.

[Hasret Sarıyer]

I installed xenomai using this guide
<http://xenomai.org/2014/06/building-debian-packages/>. And there are some
examples under xenomai2.6/examples/rtdm/driver-api folder. I
copied /driver-api folder to desktop. I executed tut02-skeleton-app file,
the output was *Xenomai: binding failed: Operation not permitted.*

I try to use rtdm modules. Which command should be executed on terminal?
For nucleus, it is xeno_nucleus.xenomai_gid=<gid>.

This is not a command to be executed on terminal, this is an option to
add to the kernel command line.

Also, first things first, could you try and run the "latency" test as
root, to see if everything is working, or if you still have the missing
/dev/rtheap issue?

I did all step on this guide
<http://xenomai.org/2014/06/building-debian-packages/>. And I expexted that
xenomai was ready to use.

Xenomai should be ready to use, the latency test is a utility part of
xenomai using xenomai, so running it as root will tell you if xenomai is
ready or if you still have other issues (actually, most issues with
beginner are kernel configuration issues).

Ok. Xenomai seems to be working on your system, and you seem not to
have any pathological latency issues.

Note that since latency output is plain text, you could have pasted it
in the mail body.

So, your last problem now, if you want to run programs as a user and
not as root, is to follow:
http://xenomai.org/2014/06/running-a-xenomai-application-as-a-regular-user/

ok. But I am not clear some points.To compile,the necessary modules are
added in makefile.

What should I do to add to the kernel? I did using "modprobe", but it
didn't work.

It depends on how you configured the kernel. As indicated in the
documentation, if you configured xenomai to be built-in, there is no
xeno_nucleus module, so you have to pass the xeno_nucleus.xenomai_gid
parameter to the kernel.

As indicated in the documentation, you can also use sysfs.

I tried three ways(as root or not), but they didn't.

What did you try, what error message did you get? Note that passing
xenomai_gid on modprobe line, and passing it on the kernel command line
need not be tried both, the one to use depends on how you configured the
kernel.

I did  configuration like this guide.
<http://xenomai.org/2014/06/building-debian-packages/#patch_and_configure_the_kernel>
When
I run "*echo "<gid>" > /sys/module/xeno_nucleus/parameters/xenomai_gid"  *as
root*,*the error was Invalid argument. As not root, the error was *"Permission
denied".*

Are you for real? <gid> should be replaced with the gid of a group of
your choice, as per the first sentence of the documentation:
"As of Xenomai release 2.3.2, you can allow non-root users to access
Xenomai services from user space. You only have to provide the ID of a
unix group whose members shall obtain this right plus additional Linux
capabilities required to work with Xenomai.

And of course you need to be root to pass this argument.
