[Xenomai-help] cyclictest -tn where n!=1 causes segfault with Kilauea

[Robert Berger]

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.

Dear Robert,

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

Best regards,

ulimit -s unlimited
-bash-3.2# ./cyclictest -t3
Segmentation fault

We are still dying somewhere here:

Program terminated with signal 11, Segmentation fault.
#0  0x0ff4e37c in xeno_fault_stack ()
   from /usr/local/xenomai-head/lib/libxenomai.so.0

Confirmed!

What's currently under git in combination with a 2.6.33 tag from the
DENX tree works now on the kilauea board.

Robert
