Hi, Nvidia  
I have a custom board using hdmi, However, when we use the HDMI screen to connect to the AGX Xavier custom board, the screen will not output any data, but you can see the Nvidia logo when AGX Xavier start up.  
Please help us check the problems related to this part.  
when we start after AGX Xavier plug in an HDMI cable.  
dmesg log in the following:

After inserting the HDMI cable for a period of time, the driver will disable AUX2 automatically if the HDMI cable is not removed.

Thank you quickly reply!  
we check full schematic, we find TX0 and TX2 sequence of lines is reversed, when we switch them, the image can be displayed normally!
