Thank you Philippe very much. Yes, it seems that Xenomail may not support the MPC870 cpu. But you mean the Xenomai with linux 2.6.34 kernel can support it, right? Another question, is there a officail document that say runing Xenomai on the mpc855 family processors needs 2.6.34 kernel?

Thank you. > I'm saying that your particular board is not known to run Xenomai, nothing else. Those which officially do are listed here: http://www.xenomai.org/index.php/Embedded_Device_Support#Supported_Architect ures In any case, if you want to run Xenomai on a processor from the mpc855 family, 2.6.34 is a requirement. > > Wenyi Gao > > -----Original Message----- > From: Philippe Gerum [mailto:[email protected]] > Sent: 2010年9月1日 15:53 > To: Gao > Cc: [email protected] > Subject: Re: [Xenomai-help] Powerpc kernel cannot boot with xenomai > > On Wed, 2010-09-01 at 15:47 +0800, Gao wrote: > > Hi All, > > > > I patched the kernel with xenomai, but the kernel "cuImage" cannot > > boot up, below is the console output: > > > > U-Boot 2009.06.00-svn21572 (Aug 24 2010 - 11:20:12) > > > > CPU: MPC885ZPnn at 100 MHz: 8 kB I-Cache 8 kB D-Cache FEC present > > This board is not supported.
