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 ?

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?
Please try the following patch:
diff --git a/arch/arm/mach-mxs/icoll.c b/arch/arm/mach-mxs/icoll.c

}
break;
Did you possibly apply this fix to mainline xenomai please ?
It is already applied (but to the I-pipe patch, not to xenomai).
