Hello, when using the PCIE x16 of AGX ORI, I meet two problems that I would like to consult.
- 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.
- 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?
I don’t get what is the point to do (1). We don’t support PCIe hotplug either.
For 2, since where you got stuck is the UEFI, if you want full log, you need to rebuild the UEFI binary and there would be one DEBUG version of binary. Reflash your system with that binary and it will enable full logs in UEFI.
But you have to make sure it is really stuck inside UEFI but not something else. If you cannot tell it, then it better still posting the log here for me to check.
You should follow my previous comment to enable full UEFI log. I don’t know what startup kernel log you want to add here. The point to get stuck is not in kernel. Adding log to kernel does not help.
