Xenomai for mx6q does not exist for linux 2.6.35. It only exists for freescale branch for 2.6.38, or 3.0, as a separate set of patches to apply before and after the Adeos patches for the vanilla kernel. For further details, see ksrc/arch/arm/patches/README in xenomai 2.6 sources. Furthermore, we have some stability issues with Xenomai for mx6q with 3.0, the issues looking a lot like an issue with cache. We would ned to recheck 2.6.38 to see if it had the same issues, but I would bet it does. -- Gilles.
