Lane reversal on UPHY2 PCIe x4 for AGX Orin

Hi,

We would like to use Jetton’s UPHY2(C7) as Configuration #2 with UPHY_RX6/TX6 to UPHY_RX9/TX9 as RootPoint in a 4-lane configuration. Is it possible to connect only these 4 lanes to EndPoint with lane reversal?

If it is possible, will Pinmux or driver modifications be required?

Best Regards,

UNA
