Hello,
I attempted to use xenomai on i.MX28-based board, but unfortunatelly
failed so far. I use mainline Linux 3.8.2 on the board with no
additional patches,
therefore I did:
git clone git://git.xenomai.org/xenomai-2.6.git
To retrieve xenomai-2.6/master . Then I went on to patch the Linux kernel
source:
./scripts/prepare-kernel.sh --linux=../linux-stable --
ipipe=ksrc/arch/arm/patches/ipipe-core-3.8-arm-1.patch --arch=arm
Next I ran "make oldconfig" in the kernel tree. I enabled XENOMAI and
left the newly added configuration options at their default values.
After compiling the kernel, the kernel does not boot on the board
anymore, while the kernel did boot before patching without problems.
Can you please give me any pointers or ideas on how to progress ?
Try:

Thanks! The earlyprintk really helped, now I see this output [1] . I suspect
it's something going on with the ipipe since I see icoll crashing. Can you
please help me some more on where to look from now on or how to fix this?
Try enabling the I-pipe tracer, and the option which causes a trace
freeze on bug. And see how you reach the point of the BUG, the one at
kernel/posix-timers.c. Looking at the code where the bug is should help
in understanding what happens too.
