Hi All,
I patched the kernel with xenomai, but the kernel "cuImage" cannot boot up,
below is the console output:

I mean that a port of Xenomai to a custom board based on a CPU from the mpc855 family is known to work, based on a 2.6.34 kernel, and that is the only port of Xenomai to this architecture I'm aware of. The latest I-pipe/powerpc patch for 2.6.34 does include that support for 8xx. Now, it should be possible for you to backport the I-pipe bits from the 2.6.34 patch required to run 8xx to 2.6.33, if your bsp is based on that release. > Another question, is there a officail document that say > runing Xenomai on the mpc855 family processors needs 2.6.34 kernel? > You are currently reading it. > -----Original Message----- > From: Philippe Gerum [mailto:rpm@xenomai.org > Sent: 2010年9月1日 16:39 > To: Gao > Cc: xenomai@xenomai.org > Subject: RE: [Xenomai-help] Powerpc kernel cannot boot with xenomai > > On Wed, 2010-09-01 at 16:11 +0800, Gao wrote: > > Hi Philippe, > > > > Are you sure xenomai(2.5.4) doesn't support the cpu MPC870?

This likely happens when the real-time core enables its internal timer when the kernel enables the first skin, in your case the pSOS one. This is usually due to an issue in the I-pipe patch. > > > -----Original Message----- > From: Philippe Gerum [mailto:rpm@xenomai.org > Sent: 2010年9月3日 13:27 > To: Gao > Cc: xenomai@xenomai.org > Subject: RE: [Xenomai-help] Powerpc kernel cannot boot with xenomai > > On Wed, 2010-09-01 at 17:02 +0800, Gao wrote: > > Thank you Philippe very much.
