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_Architectures 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.
