Why are PCI Express RX TLP Packets lost when using the AXI Streaming IP for PCI Express* at lower rates (Gen1/2/3)? - Why are PCI Express RX TLP Packets lost when using the AXI Streaming IP for PCI Express* at lower rates (Gen1/2/3)?
Description Due to a problem in the 25.1 and earlier versions of the AXI Streaming IP for PCI Express*, RX TLP packets can be lost if the IP is generated for Gen5 data rates but is actually operating at lower rates, and back-to-back small RX TLPs are received where the TLPs appear in each segment. The R-Tile Avalon® Streaming IP for PCI Express* is not affected by this problem. Resolution No workaround to this problem exists in the 25.1 and earlier releases of the AXI Streaming IP for PCI Express*. This problem is scheduled to be fixed in a future release of the AXI Streaming IP for PCI Express*.
