[Xenomai-help] Xenomai and Pandaboard

I've been trying to build a working kernel with Xenomai librarys for the
last couple of days, and keep running into snags. Its the first time I've
ever tried to build a kernel before, though I do have some experience with
Linux and embedded systems.

So far, I've tried using a cross toolchchain built using Buildroot 2011.8,
which I used to make x-loader and u-loader, both of which appear to work,
then the 2.6.38.8 kernel with xenomai 2.6.0, which seems to compile
correctly, but on boot up the board halts after unpacking the kernel (both
front lights stay on and it never tries to actually start up the hardware).
So next I tried building it on a working Ubunutu 11.10 image running on the
pandaboard, but I was never able to successfully build the kernel that way.

Any advice I could get on what I'm doing wrong would be
greatly appreciated.

Thanks,
Chris

I routinely run xenomai on pandaboard with the following kernel
configuration:

http://sisyphus.hd.free.fr/~gilles/config-panda

If it does not work for you, please try disabling CONFIG_XENOMAI and
CONFIG_IPIPE to see if the result boots.

In order to get clues about why your kernel does not boot, you can try
enabling the "early printk" option, then boot the kernel passing
"earlyprintk" on its command line.

Please keep the communications on the list. As I already suggested, if
the kernel does not boot with xenomai enabled, please try disabling
CONFIG_XENOMAI, and if it still does not work, try disabling CONFIG_IPIPE.
