I can find the below in ‘NVIDIA Jetson Xavier NX Design Guide’ document. (Jetson_AGX_Xavier_Series_PCIe_Endpoint_Design_Guidelines_DA-09357-001_v1.3.pdf).
No need to worry about it. Our software will handle the status of that pin.
Just need to modify the ODMDATA and flash the board again.
You can refer to Jetson AGX Xavier PCIe Endpoint Software on our download center for detail.
But be careful the document is for AGX Xavier. You have to modify the corresponding files for NX.
