PCIe_on_Custom_carrier_board

our custom board doesn’t have the provision to turn on the rootport and endpoint separetly. Both at a time will powered on.

So, for the PCIe configuration, after the booting of both boards, so, we are configuring the endpoint and restarting the rootport.

Most of the times, we are getting this error.

Sometimes, only the rootport is able to detect the endpoint.



using minicom, I got this


this is rootport bash screenshot.

So, is there any suggestions.

Please sharing full log as text but not such screenshot.

What is the EP device in use?

EP is same jetson-agx-orin-module-64gb

This topic is filed in wrong forum. I just moved it.

I don’t know why do you only share one log here because we have both RP and EP. You should share log from both side.

dmesg_endpoint.txt (56.7 KB)

Please refer to the AGX Orin design guide document for the endpoint hardware design section.

Hii Wayne, Nikhil this side as my PC having the issue so I’m replying from Sireesha’s account.

some times we are observing the below error log while booting endpoint.
can you please suggest to debug the issue.

Is this still an issue to support? Any result can be shared?

Hi @kayccc, I have reversed the settings, what I have made for HDMI. So, after that, PCIe to PCIe communication on custom board is working fine but one difference is there, i.e speed, the speed is 1.6 gt/s from rootport to endpoint with dummy data and on Dev-kit, it is 13 gt/s. So, is there any suggestion for that?
