Automatic Lane Polarity Inversion for PCIe Hard IP
Cyclone® 10 GX PCIe Hard IP open systems
where you do not control both ends of the PCIe link, Intel does not guarantee automatic lane polarity inversion with the Gen1x1
configuration, Configuration via Protocol (CvP), or Autonomous Hard IP mode. The link may not
train successfully, or it may train to a smaller width than expected. There is no planned
workaround or fix.
For all other configurations, refer to the following workaround.
Refer to the Knowledge Database in the related links below for details to
workaround this issue.
