Hi,
I'm using a Kilauea board:
cat /proc/cpuinfo
processor : 0
cpu : 405EX
clock : 533.333333MHz
revision : 20.119 (pvr 1291 1477)
bogomips : 1066.66
timebase : 533333333
platform : PowerPC 40x Platform
model : amcc,kilauea
Memory : 256 MB
The kernel is:
git clone git://git.denx.de/linux-2.6-denx.git
git checkout v2.6.33 -b v2.6.33_local
The adeos patch is:
wget
http://download.gna.org/adeos/patches/v2.6/powerpc/adeos-ipipe-2.6.33-powerpc-2.9-00.patch
xenomai is the latest and greatest:
git clone git://xenomai.org/xenomai-head
in the kernel dir:
make ARCH=powerpc CROSS_COMPILE=ppc_4xx- mrproper
make ARCH=powerpc CROSS_COMPILE=ppc_4xx- 40x/kilauea_defconfig
I'm patching the kernel:
export ADEOS_PATCH=adeos-ipipe-2.6.33-powerpc-2.9-00.patch
cd xenomai-head
./scripts/prepare-kernel.sh
--linux=$ELDK_PREFIX/eldk-4.2-ppc_4xx/usr/src/$KERNEL_DIR/ --arch=powe
rpc --adeos=../$ADEOS_PATCH
in the kernel dir:
make ARCH=powerpc CROSS_COMPILE=ppc_4xx- menuconfig
make ARCH=powerpc CROSS_COMPILE=ppc_4xx- uImage
EXTRAVERSION=$EXTRA_VERSION_INFO
make ARCH=powerpc CROSS_COMPILE=ppc_4xx- modules
EXTRAVERSION=$EXTRA_VERSION_INFO
make ARCH=powerpc CROSS_COMPILE=ppc_4xx-
INSTALL_MOD_PATH=$ELDK_PREFIX/eldk-4.2-ppc_4xx/ppc_4xx mo
dules_install
Build xenomai user-space support:
cd $ELDK_PREFIX/eldk-4.2-ppc_4xx/usr/src/xenomai-head
source $ELDK_PREFIX/eldk-4.2-ppc_4xx/eldk_init ppc_4xx
./configure --host=powerpc-linux --prefix=/usr/local/xenomai-head
make ARCH=powerpc CROSS_COMPILE=ppc_4xx-
make DESTDIR=$ELDK_PREFIX/eldk-4.2-ppc_4xx/ppc_4xx install
on the target:
cd /usr/local/xenomai-head/bin
./cyclictest -t2
Segmentation fault
./cyclictest -t3
Segmentation fault
./cyclictest -t4
Segmentation fault
only
./cyclictest -t1 does not give Segmentation fault
Please advise.
Regards,
Robert

Do you want me to build something like the libxenomai.so.0 with more
debug info?
If so, please tell me what exactly you want and how to enable debug.

And what happens when you start cyclictest after running
"ulimit -s unlimited" ?
Best regards,
