Jetson_AGX_Xavier PCIe interface

Hi,

Can PCIe interface(GEN4) of Jetson_AGX_Xavier connect reverse?

Thanks,

Hi,

It mean the PCIe P/N lane reversal.(Gen3 & Gen4)

Thanks,

May I ask is there any reason you cannot follow the OEM design guide?

Hi,

Because our PCIe Riser board is too small,
so need P/N lane reversal to improve layout routing.

Thanks,
John yang

Yes…lane polarity inversion works on Jetson-Xavier board’s Rx lanes… Please check whether the same is supported by the endpoint that you are going to connect to the slot.

Understand
Thank you!
