Display Port on DP1, Display Port on DP0


We have a custom carrier board for Jetson Nano with Display Port on DP1, and Display Port on DP0. Since DP0 is already configured as Display port, I am interested in what changes are required for Display Port on DP1? I have read a prior topic and made changes discussed but could not come to a working system.

I have upload the extracted.dts and a text file (includes dmesg, device Tree changes, and miscellaneous information) to aid in framing the problem.

Thank you,

Assistance no longer needed…

Could you share how it’s resolved? Thanks

Here are changes made:

nvidia,xbar-ctrl = <0 1 2 3 4>; // fixed lanes for our hw
status = “okay”;
hdmi-display { status = “disabled”; };

  •                   dp-display { status = "okay"; };

// Copied sor sections and updated nvidia,active-panel to point to sor1 instead of sor0

  •           sor1 {
  •                   nvidia,sor1-output-type = "dp";
  •                   nvidia,active-panel = <&sor1_dp_display>;
