Yeah I've been following the EMC project for a while now as well as other initiatives to build Xenomai on the BeagleBone and BeagleBoard. In fact I think that Stephan Kappertz has posted the best integration to date for the BeagleBone and Xenomai on Angstrom; however I am not aware of anyone to date that's been able to successfully integrate all of the TI patches into the kernel and then patch the kernel with Xenomai. So either you get the BeagleBone kernel with all all TI optimizations, or a generic kernel with Xenomai support, but not both. Typically this breaks support for additional things in the kernel, probably sysfs support for sysfs-based GPIO access and PWM toggling etc. So according to Robert Nelson (the TI patch maintainer for the BeagleBoard/Bone kernel), the only way to do this is to start with the Aragon kernel, apply each kernel revision patch from 3.2.0 -> 3.2.21, with the TI patch branch applied at each to arrive at a 3.2.21 kernel that has all of the TI patches integrated. I think this is the right approach, or maybe I am just shooting fish in a barrel here with this. _______________________________________________ Xenomai mailing list [email protected] http://www.xenomai.org/mailman/listinfo/xenomai
