[Xenomai-core] Runtime error on PXA270 for branch 'for-ipipe-2.6.35-arm' in 'ipipe-gch.git'

[Michael Bernhard]

Hello!

I'm trying to get running the ipipe patch on a 2.6.35 kernel. I've seen
that Gilles was working on that port lately so I gave it a try.

The kernel is booting fine. However init does not continue and the
NETDEV watchdog triggers:

The same behavior happens even if I disable FCSE and IPIPE or either of it.
I think this is pretty much what this tree contains.

A vanilla 2.6.35.9 kernel is booting fine with colibri_pxa270_defconfig.

As you see from the defconfig, the target is a PXA270 colibri board.

For me the behavior is a bit strange because the kernel already fetched
the IP address via DHCP and also mounted the NFS root file system

Does somebody have an idea in which direction I should investigate?

Of course I can provide more information if needed. We would like to
use Xenomai on this ARM board with kernel 2.6.35.

Best regards,
Michael

Hi,

please use Xenomai mailing lists, not my private address.

Does the following path help?

diff --git a/arch/arm/plat-pxa/gpio.c b/arch/arm/plat-pxa/gpio.c

Ping? Could you test this patch?

Hello Gilles

Sorry for the late answer. I tested the patch today and it really solved the problem.
I have a running Xenomai installation now.

Thanks for your help.
