This topic describes how to use the PCIE x16 slot？

Hello, when using the PCIE x16 of AGX ORI, I meet two problems that I would like to consult.

1. When no device is connected to the PCIE x16 slot, I find that the development board stops supplying power to the pcie x16 slot after the system is started. I would like to ask if there is any way to keep the PCIE x16 slot supplying power and detecting pcie devices regardless of whether there is any device connected.


2. When a pcie x16 is connected to a pcie device with a reference clock and power supply enabled, the AGX ORI development board is stuck after it prints only one log message during startup. The log message is as follows: Jetson UEFI firmware (version 3.1-32827747 built on…) What causes this? Is there any solution?
