[Xenomai-help] Problems with installation

[-- Attachment #1: Type: text/plain, Size: 700 bytes --]

Hi all

I'm quite new with Linux and Xenomai. I'm using Ubunto kernel
2.6.32-24-generic. I tied to install Xenomai-2.6 following the
README.INSTALL document. First of all I cloned the GIT repository in

/usr/src/xenomai-2.6

After that, I tried to run the prepare-kernel.sh script as follows:

/usr/src/xenomai-2.6/scripts/prepare-kernel.sh
--linux=/usr/src/linux-headers-2.6.32-24-generic/

I select the default target architecture with no problems

Target architecture [default i686]:

But when I select the default I-pipe patch i get the following:

I-pipe patch [default /dev/null]:
prepare-kernel.sh: cannot read I-pipe patch from /dev/null

What should I do?

Thanks in advance,

That is not going to work. Xenomai patches the kernel sources, and ask
you to rebuild a kernel, just supplying the headers will not work.

Thanks for your reply.

As I told you, I am really new with linux. I've been trying to find the
kernel source tree and not just the headers, but I haven't been able to do
it. I read that it is normally located in /usr/src/, but there I just have
the headers. How can I search the right path of the kernel source tree to
prepare the kernel?

Rather than using the kernel headers from ubuntu, clone a new kernel copy in /usr/src and try to patch that.

Thanks for the advise

I downloaded a new kernel and it worked. I followed the steps from
README.INSTALL successfully

$ /usr/src/xenomai-2.6/scripts/prepare-kernel.sh
--linux=/home/corbys/linux-2.6.38/
--adeos=/usr/src/xenomai-2.6/ksrc/arch/x86/patches/adeos-ipipe-2.6.38.8-x86-2.11-01.patch
--arch=x86
$ cd ~/linux-2.6.38/
$ make [ARCH=i386] xconfig
$ make [ARCH=i386] bzImage modules
$ mkdir ~/build/linux-2.6.38 && cd ~/build/linux-2.6.38
$ /usr/src/xenomai-2.6/configure --enable-x86-sep --host=i686-linux
CFLAGS="-m32 -O2" LDFLAGS="-m32"

How can I check now that my Xenomai patched kernel was installed correctly
and is ready to be used? Also, what does it mean "# then install as needed"
after 'make bzImage modules'? I just followed the steps above. Should I had
installed something else after that step?

Thanks again.

You are almost there ... Check the following for the rest of the installation steps and basic testing...

Thanks for the quick reply

I'm having problems booting into the Xenomai kernel. I get a window which
says:

*Ubuntu is running in low-graphics mode*
The following error was encountered. You may need
to upgrade your configuration to solve this.
(EE) open /dev/fb0: No such file or directory
(EE) intel(0): [drm]: Failed to open DRM device for
pci:0000:00:02.0: No such file or directory
(EE) intel(0): Failed to become DRM master.
(EE) GARTInit: Unable to open /dev/agpgart (No such file or
directory)
(EE) intel(0): /dev/agpgart is either not available or no memory
is available
(EE) intel(0): Failed to initializekernel memory manager
(EE) intel(0): AGP GART support is either not available or
cannot be used
(EE) intel(0):  AGP GART support is either not available or
cannot be used
(EE) intel(0): Couldn't allocate video memory

When I exit to the console, I see a fatal error that says

Could not load /lib/modules/2.6.38/modules.dep: no such file or directory


My grub.cfg file was edited automatically after copying the bzImage and
typing update-grub:

sudo cp /home/corbys/linux-2.6.38/arch/x86/boot/bzImage
/boot/vmlinuz-2.6.38.8-xenomai-2.6
sudo addgroup xenomai
sudo usermod -a -G xenomai corbys
sudo usermod -a -G xenomai aleu
sudo update-grub

The update-grub added the following lines to grub.cfg

menuentry 'Ubuntu, with Linux 2.6.38.8-xenomai-2.6' --class ubuntu --class
gnu-linux --class gnu --class os {
    recordfail
    insmod ext2
    set root='(hd0,1)'
    search --no-floppy --fs-uuid --set 958aeec8-5e7e-42ce-9719-136139112849
    linux    /boot/vmlinuz-2.6.38.8-xenomai-2.6 root=/dev/sda1 ro   quiet
splash
}
menuentry 'Ubuntu, with Linux 2.6.38.8-xenomai-2.6 (recovery mode)' --class
ubuntu --class gnu-linux --class gnu --class os {
    recordfail
    insmod ext2
    set root='(hd0,1)'
    search --no-floppy --fs-uuid --set 958aeec8-5e7e-42ce-9719-136139112849
    echo    'Loading Linux 2.6.38.8-xenomai-2.6 ...'
    linux    /boot/vmlinuz-2.6.38.8-xenomai-2.6 root=/dev/sda1 ro single
    echo    'Loading initial ramdisk ...'
}

I tried also by changing root=/dev/sda1 for my UUID (root=UUID=958...), but
it didn't even started. I changed as well 'quiet splash' for
'xeno_nucleus.xenomai_gid=1001' and still didn't work (same 'Ubuntu is
running in low-graphics mode' error).

What can I do now??
