Is it possible to have a distro like xenomai+ubuntu for this board? i think it would be very useful since the IO is accessible both from thesa3x and the iMX6...
The UDOO team with the help of beta testers all over the world is working on several distros and OS like Ubuntu Linaro, Yocto, Debian, Archilinux, XBMC. Android and so on. Also, the community will play a key role in developing UDOO so I guess it is just a matter of time!
Xenomai merged with RTAI some years ago. I think it is possible to apply RTAI to the UDOO kernel. It is a expensive procedure; the best thing to do is to check if exist a RTAI version that support the kernel version used for UDOO (3.0.15) or closed versions. Unluckily the Linux kernels used by RTAI are old. Keep us updated!
Sorry, but as far as I know this is not true. Xenomai is a project that is quite different from RTAI (for details see: http://www.xenomai.org/index.php/FAQs#W ... nd_RTAI.3F ). Adapting Xenomai to a new hardware is in general not so difficult. Have a look at: http://www.xenomai.org/index.php/Embedd ... ce_Support If you want to make Xenomai work on UDOO, just ask on the Xenomai mailing list. Currently the newest kernel that is supported for Xenomai on ARM is the 3.8 kernel. See: http://download.gna.org/adeos/patches/v3.x/arm/ The version for which Xenomai patches exist that is most close to the version UDOO is using is version 3.0.13 . For my purposes a low-latency kernel is already good enough, though. Best regards: Uwe Fechner

i want to make xenoami running on uddo is it possible ? and is it efficient for real time applications ?
i need RTOS on my UDOO board so when i searched i found that xenoami is real time framework for linux so i try to apply it for my udoo board so i asked is it good solution ? anyone succeed to do that on udoo ?
According to Xenoami website, i.MX6Q boards, that is UDOO Quad, are supported, so it should work. Anyway I've never tried it, so I don't know if it's good or not.
I never saw this reply. I know it is years later, but that was the output of running the Xenomai testsuite on a Udoo Quad. (ie, proof that Xenomai worked on Udoo)
