[Buildroot] xenomai / ratai --> nee ipipe

[Jens Kleinhans]

I used RTAI, so I don't want to use Xenomai. Is there another possibility to add the ipipe?




Looks like you miss-applied a xenomai patch or you're using a xenomai patch that does not support the arm architecture...

        /path/to/your/buildroot/build_arm/staging_dir/usr/bin/arm-linux-
        
        should work.

        Hi Daniel I thanks for this information. But when I type I get the following problem. The ipipe directory is missing.  When I do the menuconfig of the Linux Kernel with "$ Make ARCH=arm menuconfig"  no option about ipipe appears. Have you an idea how to solve this problem

Please use your mail client's REPLY function so everyone can see what
your emails refer to. Great feature, really.

For your actual problem, please give a hint about what kernel version
you used and whether you patched it and how.

Not sure though if people on this list can help much with AT91 specific
things; you might get more in-depth help from other sources.
