Samtec PCIe board for MTP camera connection

i am new with these items, i am trying to connect a camera with MTP interface to the jetson agx developer kit. To make the connection I mounted a samtec PXH842 adapter on the PCIe slot of the jetson, but it doesn’t seem to work, any suggestion? is the jatson slot only x8? i think the card is x16, is this the problem?
Thank you

Hi, please refer to the doc Jetson AGX Xavier Developer Kit Carrier Board Specification for PCIe port details in DLC.
