AXI Bridge for PCI Express - Root Port Implementation does byte swap to the completion packet for a configuration read issued to an Endpoint device

描述

Version Found: v1.03a, v1.04a
Version Resolved and other Known Issues: see (Xilinx Answer 44969)

When operating in Root Port mode, if configuration read packets were sent to an Endpoint device, the returned completion from that configuration read will be byte-reversed by the AXI_PCIe bridge of the Root Controller.

解决方案

The example Root Controller driver provided by Xilinx will automatically handle this situation. Users who write their own driver should be aware of this issue and make sure that their driver handles this issue correctly.

This information will be added into the next release of the documentation.
