PCI 1510 Windows Embedded 7 Problems

Other Parts Discussed in Thread: PCI1510

I'm hoping someone here will be able to offer some assistance.  We've embedded the PCI 1510 Cardbus chip into our board.  We're running windows embedded 7 standard (yes, the PCMCIA driver package is installed).  Most of the hardware is fully functional with this being the last holdout.

The 1510 is detected by the operating system.  It has a driver, but device manager is reporting error code 31.  A more specific problem code is 1F, which I believe means invalid data.


Reading the PCI Configuration Space for the device shows me that it hasn't been programmed.  No BARs, no PCI Bus/Device, it looks to contain only that which was read from the EEPROM.  Windows does have a bus/device assignment for it.  I am certain it is reading from the EEPROM at boot.


The device is attached to a PEX 8112, PCIe to PCI bridge.  There is another device on the PCI bus and it is currently working with no problems.

Any help you can provide would be greatly appreciated.

    Hello,

    Can you provide a PCI Register dump pf the PCI1510?

    Can you provide your schematic for review?

    If you don't want to make your data public you can provide an email address and we will contact you.

    Regards

    Hey Elias,

    Thanks for the response.  I'm currently awaiting permission to provide you with schematics (might require NDA) and will not be able to provide them publicly.


    Is it possible for you to email me at the address registered to my account?  I try not to post my email address on public forums, leads to spam.

    As for the register dump... no concerns there.
