How to screen output Jetson nano module to DP port on Jetson Orin Nano custom board?

hello.
I would like to ask for a solution.
I made a custom board to run a jetson nano and it worked fine.
In the future I want to use the jetson orin nano, so I made a custom board looking at the reference circuit.

I haven’t gotten my hands on a Jetson Orin Nano yet, so I want to run the Jetson Nano on this custom board.
I ran into an unexpected problem.
The Jetson Orin Nano comes standard with a DP port.
On the Jetson Nano, I am connected to DP ports DP0_TXD0~3, and on the Jetson Orin Nano, I am connected to USB Type-C.

It is my understanding that DP1_TX0~3 supports HDMI and DP simultaneously.
I would like to know how to output the screen on the Jetson Nano to DP1_TX0~3 (on the Jetson Orin Nano, it is DP port).

Thanks.

Is this issue talking about Orin Nano or Jetson nano?

Your last question sounds like you want to ask something for Jetson nano??

I would like to know how to output the screen on the Jetson Nano to DP1_TX0~3

My custom board is designed to be used with both the Jetson Orin Nano and the Jetson Nano.
First of all, I would like to mount a Jetson Nano module to control the Jetson Nano by displaying the DP1_TX0~3 signal on the screen as a dp port.
I want to block the existing dp port DP0_TX0~3 signals.

So you already designed that hardware as DP port? Any schematic to review?

For jetson nano software, please refer to the original dts to modify the tegradc of original HDMI into DP.

Original design:

tegradc.0 → sor1 → HDMI setting
tegrdc.1 → sor0 → DP setting.

If you want DP1 to be DP, then need to modify tegradc.0 → SOR1 setting to DP one.

PCB design and component assembly is complete using the reference circuit.

I have other issues and will get back to you later.
Thank you.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

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