[Xenomai] Installing Xenomai Newbie

[Xenomai] Installing Xenomai Newbie

[Sebastián Pavez]

Hi,

My name is Sebastian and I'm a chilean student from PUCV. Currently I 
have to develop a RT proyect, but the problem is that I dont have 
experience with Linux and a lot less with Xenomai. Nevertheless i 
arrived to install xenomai  2.6.0 on Ubuntu 12.04, but when I try to 
execute ubuntu with the xenomai kernel the screen goes black and the 
computer doesn't respond, so I have to execute it with the recuperation 
mode. In this case I'm able to execute the test for the kernel and 
latency wich are ok, but the system seems unstable (the cursor sometimes 
disappear for instance), and I couldnt execute Xenomai, I receive a 
message of "premission denied".
So, I'll appreciate if someone could give me a hand with the starting 
problem and the execution too. I was considering to do all the process 
again from the scratch but i don't know how to erase all the changes I 
have made in my computer.
Thanks for your time, and for your help.

PS: I utilise this configuration 
http://www.blaess.fr/christophe/files/article-2012-05-02/config-linux-2.6.38.8-xenomai 
according to this tutorial 
http://www.blaess.fr/christophe/2011/12/28/xenomai-2-6-0-sur-ubuntu-11-10/

Please remove "quiet" from Linux command line, and make sure that you
have all the drivers necessary for the your system to boot, including:
- video display driver
- root file system device driver
- root file system driver

Xenomai 2.6.0 is installed on Fedora.

For Ubuntu we had to use another older version of Xenomai

Xenomai is distribution agnostic, you should be able to run the latest
version of Xenomai with any reasonably recent distribution. So, could
you describe the particular problems you had running Xenomai on ubuntu?

Dear Gilles,

My friend could not install it on Ubuntu. The reason was the script
which Xenomai, 2.6.0,  is built with is run on Fedora correctly.

Please post some concrete error messages, that we can help people debug.
And you will see that we can install xenomai 2.6.1 on Ubuntu.

Hi,

I tried to everything from scratch, but i get the same problem. I tried 
remove the quiet splash and I could see the line
"Fallback graphics default" well, this is when I execute the kernel with 
xenomai in recovery mode. Because when I tried it in
a normal way I get the blacl screen with a twinkle, in this case I'm 
able to put my password and I heard the entry sound (with some 
distorsion), so like you said it maybe some driver's problem.
In the recovery mode I checked the application drivers and nothing. 
Maybe it's something simple but I'm quite stuck, I've never used linux 
before and I really need to get this operative, so if you or someone 
else could help me ... in plain language would be awesome ...
Thanks in advance

PS: In the recovery mode I tried the xenomai tests, I attached the 
captures ...

Your problem is configuring the kernel. So, please start with the Ubuntu
kernel configuration, and simply disable the problematic options
described here:
http://www.xenomai.org/index.php/Configuring_x86_kernels

If you do not know how to configure and compile a kernel, I suggest you
read some documentation on the web, such as:
http://kernelnewbies.org/KernelBuild

Thanks Gilles for your answers and time.

I tried one more time from scratch. I used Xenomai 2.6.0 and the kernel 
Linux 2.6.38.8.
The only changes I made in the configuration are the suggested in the 
page you send me (_CPU_FREQ, _APM, _ACPI_PROCESSOR _INTEL_IDLE, 
_PCI_MSI), I also disable _CC_STACKPROTECTOR and in the Preemption Model 
i choose "Preemptible Kernel (Low-Latency Desktop)". I have a i3 
processor so I choose the Core 2/newer Xeon's Processor family.

I got the same result (black screen with the sistem apparently working 
behind like I said), I realise that I didn't follow the recomendations 
mentioned in this page http://kernelnewbies.org/KernelBuild, because I 
tried to follow this tutorial 
http://www.blaess.fr/christophe/2011/12/28/xenomai-2-6-0-sur-ubuntu-11-10/ 
. So tomorrow I will try to do this on my own with newer versions of the 
kernel and probably with xenomai 2.6.1.

Before that I would like to know if the configuration parameters I 
choose are ok, I don't know how to get a list of all of the parameters 
to put it here but the only changes I made are the ones listed above. I 
have doubts with Preemptible Kernel option because it wasn't listed on 
the page, so I really don't know what is the cause. If it's not a 
configuration issue, could be other causes to my problem?? ... I hope 
not, because at least it's delimited.

Thank you very much for your help and please don't give up with me :)
Best Regards.

You forgot to disable KGDB.

Well, I did it again disabling the KGDB and the results are the same.
I attach the .config file like you suggested.

Ok, try compiling the kernel without running prepare-kernel.sh, but

So, the problem is not related to Xenomai, but a configuration issue of
the Linux kernel for your particular hardware configuration. When you
have find help for this issue at some other place, we can help you with
Xenomai installation.

Ok, thanks for your time. I'll do that and hopefully I'll come back with
more questions related with working on xenomai and not about the
installation.
