Re: Embedded Linux with Xenomai support

Asier <atamayoarbide@...>
 

Thank you for all your answers.

As Robert Berger wrote, Xenomai is a patch that you need to apply to the kernel and then compile it. I haven't done it yet, but I think there might be some difficulty if patching an already patched kernel. Is this the case in the Yocto distributions?

Building the userland stuff may also be quite ardous.

I want hard real-time. Really, it might be enough with soft real-time, but I don't want to take the risk. The real-time system has a 1ms period.

Wolfgang, do you plan to support x86 architecture?

I'll ask Denx, as well as Wind River and Enea about Xenomai and x86 support for their Linux distributions. If I get through something, I'll let you know.

Best regards,

ELDK adds full Xenomai support starting with release v5.4 ; please see
www.denx.de/wiki/view/ELDK-5 for details, or feel free to ask for more
details on the ELDK mailing list, see

ELDK primarily supports ARM, MIPS and Power architectures.  We didn't
test the Xenomai stuff on x86 yet.

Best regards,
