How to implement the reverse of PCIe lane[0..3]

I see a sentence in the datasheet of TX1: "In order to ease routing, the order of lanes for. Lane 4, PCIE#0_2 on Lane 3, etc.). I want to know how to configure reverse to achieve reverse.

Could you share which document and page number?

Hi,

I see it. It is in the OEM product design guide. In fact, this is just for those configuration with 4-lanes.

Thank you. I just want to know how to realize the reverse of this four lane, and how the software needs to operate to complete the reverse .

I am checking the configuration in driver. Thank you for your patience.

Even with lanes reversed, controller is able to enumerate the device as it supports lane reversal.
