描述

The SP605 PCIe x1 Gen1 Design Creation document (XTP065) outlines the steps to generate and run the PCIe x1 Gen1 design on the SP605. By following this document, I can configure the SP605 from the SPI PROM. However, there are PCIe errors, for example "PCIe not detected by PC", etc.

What could be the root cause?

解决方案

This behavior has been noted if the CF card is enabled while attempting to detect the PCIe.

The CF card on the SP605 is enabled if S1 #4 is enabled.

The PCIe is correctly detected once the SystemACE CF card is removed from the SP605 before bringing up the PCIe link, or if S1 is set to '0000'.

XTP065 v13.3 has been updated with the information that S1 should be set to '0000', explicitly telling customers to disable the SystemACE interface through this switch setting.
