[Xenomai] "Xenomai Posix skin init: pthread_setschedparam: Device or resource busy" in ARM IgepV2 Orocos+Xenomai

[Jose Ignacio Cazalilla Morenas]

Hi all.
I'm trying to use Xenomai+Linaro under a IGEPv2, in order to install  
Orocos (with the RT_TARGET=xenomai).
I've been working with the IGEPv2 and ROS+Orocos, but with the  
RTT_TARGET=gnulinux, instead of Xenomai.

Now, I've downloaded from git.isee.biz the kernel patched with Xenomai:

$git clone git://git.isee.biz/pub/scm/linux-omap-2.6.git
$cd linux-omap-2.6/
$git checkout linux-2.6.35.y-rt
$make ARCH=arm igep00x0_defconfig
$make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- zImage modules
$sudo make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-  
INSTALL_MOD_PATH=/media/root modules_install

/*Copy&Paste the zImage to the Boot partition*/

When I run the IgepV2, the kernel informs that Xenomai have been  
installed properly (dmesg).

[ 0.108093] I-pipe: Domain Xenomai registered.
[ 0.108123] Xenomai: hal/arm started.
[ 0.109252] Xenomai: scheduling class idle registered.
[ 0.109283] Xenomai: scheduling class rt registered.
[ 0.117645] Xenomai: real-time nucleus v2.6.0 (Movin' On) loaded.
[ 0.117675] Xenomai: debug mode enabled.
[ 0.118164] Xenomai: starting native API services.
[ 0.118164] Xenomai: starting POSIX services.
[ 0.118316] Xenomai: starting RTDM services.


Then, I have to install Xenomai at the user-space in order to use it  
with Orocos (or other application), so I did (inside the IGEPv2, an  
ARM embedded board):

wget http://download.gna.org/xenomai/stable/xenomai-2.6.0.tar.bz2
tar jxf xenomai-2.6.0.tar.bz2
cd xenomai-2.6.0
./configure CFLAGS="-march=armv7-a -mfpu=vfp3 -marm"
make
make install

If I run /usr/xenomai/bin/xeno-test, it works fine (it seems).

So, I compile Orocos. It detects the Xenomai installation and compile.
However, when I run "deployer-xenomai" in order to start Orocos, I get  
this error:

root@igep2:~/orocos/orocos-toolchain# deployer-xenomai
Xenomai Posix skin init: pthread_setschedparam: Device or resource busy

Therefore, it doesn't work due to this error: "Xenomai Posix skin  
init: pthread_setschedparam: Device or resource busy".
I think it could be related to the configuration of Xenomai at the  
user-space for the IGEPv2.
Any idea?

Regards,
Jose

Do you have the same issue with Xenomai latest release, that is Xenomai
2.6.3?

Thanks for your answer, Gilles.
I'm just installing Xenomai 2.6.3 for the user-space, with the kernel  
patched with Xenomai 2.6.0 (this kernel is provided by IgepV2  
developers). I don't know if different versions of Kernel and  
user-space are suitable...

If it is unsuccessful, I'll patch the sources with Xenoami latest  
release 2.6.3.
Do you agree?

Xenomai 2.6.3 is ABI and API compatible with 2.6.0. However a lot of
things have been fixed since 2.6.0. Besides, I routinely test Xenomai on
IGEPv2 board, so I am pretty sure that the vanilla kernel works on IGEP,
you do not need to rely on a fork.

Which vanilla kernel do you mean exactly?
Maybe this one for omap devices?

Only to inform that using Xenomai 2.6.3 at user-space (instead of  
2.6.0), and Xenomai 2.6.0 in the kernel, WORKS FINE WITHOUT ERRORS.  
However, I'm going to compile and patch a vanilla kernel in order to  
use the same version of Xenomai (2.6.3) in my IgepV2, following the  
advice of Gilles.
