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
