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
