I have a Raspberry Pi Compute Module 4 with an IO Board. I want to run Xenomai 3 and 4 on it. PCIe should work, so it recognizes my network adapter. I have built some Xenomai Kernels activated the Broadcom Brcmstb PCIe controller, but due to that I get a Kernel Panic during boot If I blacklist pcie_brcmstb it starts Xenomai normally, but if I type lspci there is no output. I am not sure if I am missing something... This is the output during boot:

I have installed xenomai 2.4.8 in Ubuntu 11.04 with this command: apt-get install libxenomai-dev Now I want test a simple vxWorks program, but when I compile my program, I receive this message: > Xenomai: vxworksskin or CONFIG_XENO_OPT_PERVASIVE disabled > (modprobe xeno_vxworks?) ...and the output of modprobe xeno_vxworks is: > FATAL: Module xeno_vxworks not found My question is, how can I eanble the xeno_vxworks module?

I've been trying to install xenomai on debian and I'm confused about all the version numbers. I'm on Debian 6 (Linux debian 2.6.32-5-686 #1 SMP Tue May 13 16:33:32 UTC 2014 i686 GNU/Linux) Steps I followed, 1. installed the linux-patch-xenomai from apt via aptitude install linux-patch-xenomai 2. then according to /usr/share/doc/linux-patch-xenomai/README.Debian I need the kernel source. I got the kernel source via aptitude install linux-source-2.6 3. expand the source tree tar -xvf linux-source-2.6.32.tar.bz2 in /usr/src/ 4. then apply the patch as explained in the above README.Debian by /usr/src/kernel-patches/i386/apply/xenomai which fails 1 out of 4 hunks FAILED -- saving rejects to file arch/x86/kernel/process_64.c.rej 1 out of 6 hunks FAILED -- saving rejects to file arch/x86/mm/fault.c.rej 1 out of 15 hunks FAILED -- saving rejects to file kernel/sched.c.rej 1 out of 1 hunk FAILED -- saving rejects to file kernel/signal.c.rej Why is this failing even though the above README.Debian states This is intended for vanilla and Debian kernel sources? I know debian 6 is eol but any help is appreciated.

I tried to install Xenomai 2.5.5.2 on my Ubunto 12.04 PC following the steps in [this guide](http://www.stanley.gatech.edu/skelly/uncategorized/installing-xenomai-on-ubuntu-12-04/#comment-3379) . I haven't changed any configuration options. When I run sudo ./trivial-periodic, I get a message saying Xenomai: /dev/rtheap is missing How can I resolve this error?

I am using Xenomai linux, and I have internet on it, but when I do apt-get update or apt-get install I get like this `http://security.debian.org/dists/etch/updates/contrib/source/Sources.gz 404 Not Found [IP: 212.211.132.250 80] ` I understand it has to do with unsupported repositories, but I googled around, but couldn't find what I need to do to fix it for Xenomai. This is my /etc/apt/sources.list: # # deb cdrom:[Debian GNU/Linux 4.0 r3 _Etch_ - Official i386 NETINST Binary-1 20080218-14:15]/ etch contrib main deb http://ftp.nl.debian.org/debian/ etch main deb-src http://ftp.nl.debian.org/debian/ etch main deb http://security.debian.org/ etch/updates main contrib deb-src http://security.debian.org/ etch/updates main contrib

I install xenomai by sudo apt-get install xenomai-* It installed dctrl-tools libxenomai-dev libxenomai1 linux-patch-xenomai xenomai-doc xenomai-runtime. But when I check /boot/grub/grub.cfg, it seems it didn't change anything. How do I boot xenomai on Ubuntu 10.04? Should I followed Building Debian packages 's Building a Xenomai patched Linux kernel package? But it uses kernel 2.6.35, which is newer than mine (2.6.32). Thank you~

The source folder of rtnet contains only the above mentioned files for compilation purposes. Remaining files are the source code of the examples. Question is that do these files indicate that they have been generated through automake? If yes, then where should I look to find out what settings where made to configure automake for generating these files?

From here: http://www.xenomai.org/index.php/RTnet:Installation_%26_Testing#Testing_with_a_single_node_.28local_loopback.29 > TODO: simplify the following steps. - Then you need to edit the file rtnet.conf under the /usr/local/rtnet/etc folder for the correct setup to run RTnet.
