[U-Boot-Users] MPC832x EMDS and PCI expansion board

Hi all,

I am trying to get the Freescale MPC832X EMDS with a PCI-Exp board to 
recognise a PCI device.  I have the PCI enabled @66Mhz and all appears to be 
in working order except there are no sane values are being read from the PCI 
bus.

On linux 2.6.22 kernel it registers a lots of PCI devices but they all have 
the vendor ID of 0. (<sarcasm>I really dont believe the board has a nCipher 
HSM and a SCSI controller on the PCI board.. unless its so small I cant see 
it </sarcasm> 

The Bus powers up, the cards at least get power as far as I can see (blinking 
light on a 3COM network card :-P 

Is there anything I am missing? as I cant seem to get this blessed PCI running 
properly.


any hints or suggestions? 

Best Regards
Richard
