Hello!
I've installed Xenomai for a 2.6.24 linux kernel, for a PPC development
board. My intentions are to use a NI DAQ card for a distributed control
application using RTAI skin + Comedi. So I experience some trouble after
installing Xenomai and even running specific latency , switchtest...etc or
even cmd_read, cmd_write apps because I get a Segmentation Fault each time.
So during my kernel booting i get :
I-pipe: Domain Xenomai registered.
Xenomai: hal/powerpc started.
I-pipe: Domain IShield registered.
Xenomai: real-time nucleus v2.5-devel (Flying In A Blue Dream) loaded.
Xenomai: starting native API services.
Xenomai: starting POSIX services.
Xenomai: starting RTDM services.
Xenomai: starting RTAI emulator.
So I think it's ok, but I,ve copied my generated xenomai dir (including :
bin include lib sbin share) and dev directory in my filesystem located on a
SATA hard-drive conected to my board. Am I missing something in the
installation steps ? Here are the main staps used for the installation :
/home/haustiq/development/xenomai-comedi-trunk/scripts/prepare-kernel.sh
--arch=powerpc \
--adeos=/home/haustiq/development/xenomai-comedi-trunk/ksrc/arch/powerpc/patches/adeos-ipipe-2.6.24-powerpc-DENX-2.1-04.patch
\
--linux=/home/haustiq/development/eldk/ppc_6xx/usr/src/linux-2.6.24
cd /home/haustiq/development/eldk/ppc_6xx/usr/src/linux-2.6.24
mkdir staging_dir build_root
make ARCH=powerpc CROSS_COMPILE=ppc_6xx- O=build_root menuconfig
make ARCH=powerpc CROSS_COMPILE=ppc_6xx- O=build_root uImage modules
cd build_root
/home/haustiq/development/xenomai-comedi-trunk/configure
--prefix=/home/haustiq/development/eldk/ppc_6xx/usr/src/linux-2.6.24/staging_dir
--build=i686-pc-linux-gnu --host=ppc-unknown-linux-gnu CC=ppc_6xx-gcc
CXX=ppc_6xx-g++ LD=ppc_6xx-ld
make ARCH=powerpc CROSS_COMPILE=ppc_6xx-
DESTDIR=/home/haustiq/development/eldk/ppc_6xx/usr/src/linux-2.6.24/staging_dir
install
In staging_dir I have my genrated xenomai and dev folders copied in my FS .
So when runnig for example strace ./latency on my target I get :
/usr/xenomai/bin # strace ./latency
execve("./latency", ["./latency"], [/* 8 vars */]) = 0

WHAT AM I MISSING, I SEE PLENTY OF No such file or directory !! WHERE SHOULD
I FOUND THOSE MISSING FILES, SIMLINKS....
THANKS IN ADVANCE !
