AXI Bridge for PCI Express v1.04.a - The core replies with incorrect data when reading Configuration Space for invalid Devices

Description

Version Found: v1.04.a
Version Resolved and other Known Issues
: See (Xilinx Answer 44969)

With the maximum number of devices on all buses limited to 1 on the bridge RC and EP configurations, configuration reads of first DW of the space of the other subordinate buses (bus numbers >= 2 on which no PCIe devices are available) gives 0x00000000 instead of 0xffffffff.

Solution

This is a known issue to be fixed in the next release of the core.

Note: "Version Found" refers to the version where the problem was first discovered. The problem might also exist in earlier versions, but no specific testing has been performed to verify earlier versions.
