Most likely, you're using a wrong DPRAM range. This reminds me this problem "All-ones problem with FCC1 on MPC8541" http://ozlabs.org/pipermail/linuxppc-embedded/2004-November/016050.html so double check your manual. The MPC8555E manual is still wrong in this regard, and no errata has been issued yet. -- Stephane
