Hello,

I am currently working on a project which requires realtime use of a be= agleboard. I know that Xenomai is a realtime kernel however, our setup call= s for the use of Mathworks' Simulink support for RTAI. I have been doing some research and have found that Xeno= mai incorporates RTAI as a skin? I am not entirely sure what that means but= it sounds like I can simply copy and paste RTAI headers in the designated = ../rtai folder within Xenomai and have my rtai programs compile and run on Xenomai.

Here is an outline of the goals I would like to achieve:

Have Xenomai running on a beagleboard with a= n RTAI skin
Generate realtime programs w= ith the Simulink support for RTAI
Upload= the program and run it on the beagleboard

I have a few questions regarding this approach:

First of all is this even feasible?

Secondly if it is, what would be the consequences of running an RTAI e= xecutable built on say <ubuntu 9.04 kernel 2.6.28.7 with gcc 4.3.3&= gt; on <Xenomai 2.5.2 Kernel 2.6.28.10 (adeos-ipipe-2.6.28.10-arm-1.12-07) patch with gcc 4.3.3> (this is the closest kernel match I could find)

Or if I wanted to run a later Xenomai such as <Xenomai 2.5.6 Kernel= 2.6.33 (adeos-ipipe-2.6.33-arm-1.18-02) patch with gcc 4.3.3>=

Which leads me to my next question, what is the earliest kernel + = Xenomai combination supported on the beagleboard?

I hope my questions were clear and made sense, I am new to Xenomai.

Regards,

I do not think so. Xenomai RTAI skin was a kernel-only skin, and chances are that the code generated by simulink is for LXRT, that is, RTAI user-space support. However, there exist equivalent solutions to RTAI-lab for Xenomai. We have seen a post recently about such a solution: https://mail.gna.org/public/xenomai-core/2011-10/msg00019.html A user of Xenomai, "Michel He" seems also to have worked on that too.

Note that it does not make sense to pick a release in a branch which is not the latest, for instance, if you pick a release in the 2.5 branch, it should be the latest, that is 2.5.6, previous adeos patches work with latest releases anyway. What is the reason for picking an old version of the Adeos patch? When starting a new project people usually pick the latest kernel. Anyway, the oldest version of the Adeos patch supporting omap3 should be 2.6.31. -- Gilles.
