This said, this does not mean that such port does not exist elsewhere, it does happen that ports to non-proprietary hardware remain undisclosed and get never submitted upstream for whatever silly reason. For instance, I know for sure that there are at least three different Xenomai/MIPS port bit roting in various basements all around the world with people stuck to outdated Xenomai releases, and still no MIPS support in Xenomai mainline. Anyway, back to the initial question, maybe you should ask Dr. John Williams regarding RTAI/Microblaze. Xenomai/Microblaze would be achievable, no doubt about it (e.g. we do support uClinux/Blackfin), but there has been no sign of such port yet. > Thanks, > Brendon. > > _______________________________________________ > Xenomai-help mailing list > Xenomai-help@domain.hid > https://mail.gna.org/listinfo/xenomai-help > -- Philippe.
