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
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
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.
