PCI1520: Code 12, resource management issue in Windows Device Manager

Part Number: PCI1520

Hello,

I have an XIO2001 PCIe-to-PCI bridge in front of a PCI1520 cardbus controller.  Upon card insertion, Windows Device Manager is reporting Code 12 - not enough resources.  Wondering if there are special register writes required for allocating I/O Space correctly with this configuration, or if they are required for interrupt reporting.

Thanks,

Steve

  • Hi Steven,

    Section 3.2 of the XIO2001 EVM guide addresses Code 12 issues: www.ti.com/.../scpu031b.pdf

    It looks like you just need to disable one of the other devices on your system. Unfortunately I'm not aware of any special register writes for allocating I/O space.

    Regards,
