Version Found: v1.1
Version Resolved and other Known Issues: See (Xilinx Answer 47441)

When trying to send Memory Read TLPs to the link partner, the Virtex-7 FPGA Gen3 Integrated Block for PCI Express v1.1 core does not transmit those TLPs even though the TLPs are correctly presented to the core by the backend endpoint user application. There is no issue with completion TLPs.

解决方案

This is a known issue to be fixed in a future release of the core. As a workaround, set the "AXISTEN_IF_RQ_PARITY_CHK" parameter to 'FALSE'. This parameter is set to 'TRUE' by default. This parameter can be found in pcie_3_0_7vx.v file in 'source' directory.

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