Jetson TX2 NX Custom Board PCIe as second USB 3.0

Hello,

I designing a custom carrier board for the Jetson TX2 NX.

I need at least two USB 3.0 connections to the Jetson for my application.

The pinmux spreadsheet provided by Nvidia allows me to set pins in the UPHY section for PCIE0 to superspeed pins for a USB 3.0 interface similar to the TX2.

I see the datasheet only advertises a single USB 3.0 connection.

Could I simply set the pinmux correctly and skip out on an external USB hub if I do not plan on using the PCIE0 pins for a PCIE application?

Would this be supported?

Cheers

Eric
