AXI Bridge for PCI Express v1.07a - Root Port cannot Enumerate (Send Configuration Packets) to Devices with Non-Zero Device Number

Description

Version Found: v1.07a
Version Resolved and other Known Issues: See (Xilinx Answer 44969).

Root Port cannot enumerate (send configuration packets) to devices with non-zero device number.

Solution

This is currently a limitation in the core and is also documented in the Product Guide for this core.

To work around the issue, use the attached patch (axi_pcie_v1_07_a_axi_enhanced_cfg_slave.v file) for AXI Bridge for PCIe core v1.07a only. The patch has not been tested with older AXI Bridge for PCIe core versions.

To apply the patch:

  1. Upgrade the AXI Bridge for PCIe core to v1.07.a released in ISE 14.5 tool.
  2. Make the AXI Bridge for PCIe core local by right-clicking the core, then choose Make this IP local within XPS tool.
  3. Navigate to the project_directory/pcores/axi_pcie_v1_07_a/hdl/verilog and replace the core_name_a_axi_enhanced_cfg_slave.v file with the attached file in this answer record.
  4. Within XPS tool, select Project -> Clean All Generated Files to remove any implemented design.
  5. Re-run Synthesis and Implementation.


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