It works! Thanks Greg!
If you're interested, I can post a script that do all the work!

Re: [Xenomai] Issue with Xenomai 3.0.6, I-Pipe 4.9.51 and Linux 4.9.51 on Xilinx Zynq 7000 MPSOC

[Salvatore Barone]

Thanks, but I have to got it by myself. It's a matter of principle now!
Can I patch the 4.14 Xilinx Kernel with the 4.9.51 I-Pipe patch and get
Xenomai working on it?

 If you load a non Xenomai kernel do you see the panic?  I think
 there's an issue with your rootfs. I've tested zynq running on 4.14
 ipipe and 4.9 ipipe with Xenomai 3.0.x stable using both a ubuntu and
 busybox file system with no issues.  I've tested on Zybo, Minized and
 the Zc702 board.  If it's a rootfs problem and not Xenomai related I
 can help you off list.  Try loading a non Xenomai kernel and see if
 the panic still exists.

Re: [Xenomai] Issue with Xenomai 3.0.6, I-Pipe 4.9.51 and Linux 4.9.51 on Xilinx Zynq 7000 MPSOC

[Salvatore Barone]

No, I'm patching the 4.9.51 mainline Linux Kernel with the 4.9.51 I-Pipe
patch. I'm using Xenomai 3.0.6 library and Linaro latest debian root
filesystem (2017 something)

Sounds good, and I will test out the 4.9.51 patch tonight and see what
happens.

Re: [Xenomai] Issue with Xenomai 3.0.6, I-Pipe 4.9.51 and Linux 4.9.51 on Xilinx Zynq 7000 MPSOC

[Greg Gallagher]

You can clone this:
git://git.xenomai.org/ipipe-arm.git

Then when you patch the kernel with scripts/prepare-kernel.sh leave
--ipipe= blank or not add that argument.  If you add --verbose to
prepare-kernel you should see that the script detects the ipipe is
already present in the tree and then just creates the symlinks.  Or at
least that's how I think it works :)

okay, I will try to reproduce tonight.  If you need to be up and
running i can send you a 4.14 image, (4.14 kernel with Ubuntu 16.04
fs) to test out.

Re: [Xenomai] Issue with Xenomai 3.0.6, I-Pipe 4.9.51 and Linux 4.9.51 on Xilinx Zynq 7000 MPSOC

[Greg Gallagher]

git clone git://git.xenomai.org/xenomai-3.git
git checkout stable-3.0.x

When was the last time you sync'd with the Linux stable tree?

 Are you patching the Xilinx Linux kernel with the Xenomai patch? Have
 you tried mainline?

[Greg Gallagher]

My email cutoff the last part of your panic, I can see the full log now.
Try using the latest git repo, so checkout the stable-3.0.x branch for
Xenomai.  The only difference between my test setup is I'm using the stable
branch.  I'll attempt to reproduce tonight if you still see the error.

Re: [Xenomai] Issue with Xenomai 3.0.6, I-Pipe 4.9.51 and Linux 4.9.51 on Xilinx Zynq 7000 MPSOC

[Greg Gallagher]

If you load a non Xenomai kernel do you see the panic?  I think
there's an issue with your rootfs. I've tested zynq running on 4.14
ipipe and 4.9 ipipe with Xenomai 3.0.x stable using both a ubuntu and
busybox file system with no issues.  I've tested on Zybo, Minized and
the Zc702 board.  If it's a rootfs problem and not Xenomai related I
can help you off list.  Try loading a non Xenomai kernel and see if
the panic still exists.
