Hi,
I designing a mothere board for the AGX Orin.
I would like to connect 2 M.2 key M to to the AGX orin.
When using the config #1 and the connection is-
M.2 key M #1 to UPHY22-23 and UPHY10-11 (as the EVB).
M.2 key M #2 to UPHY12-15. I don’t know how to connect them.
Is UPHY 12 connect to PET0 or PET3?

Hi,
Can I use the same PEX_WAKE_N for both M.2 key M?

Sorry for the late response, is this still an issue to support? Thanks

Sure, as said in DG: Wake signal shared by all PCIe interfaces.
