Check I/F Mapping when connecting 2-Lane EP Device to PCIe Controller #4 of AGX ORIN

I would like to connect an EP Device that supports 2-Lane to Controller #4, which supports 4-Lane, among AGX ORIN’s UPHY0.

Referring to Reference Schematic, the PCIe 2-Lane and Clock to be used were selected as follows.

Please check if there are any problems with the connection between AGX ORIN and EP Device as shown below.

Please try to use UPHY_RX22/TX22 and UPHY_RX23/TX23 instead.

Thank you for confirmation…

I understood that you were guiding UHPY Mapping as shown below.
Is that correct?

Yes, use lane 4&5 instead of 6&7.
