Hello
I am currently trying to build my own NVIDIA carrier board.
I want to modify the interface of the display port during the development process, and I have the following questions.

  1. The current display interface of Orin is DP port. I want to design the circuit by changing this port to HDMI.
  2. I am curious about how to change the port to do so.
  3. Also, I would like to ask if BSP modification is required within the L4T environment.
    (Reference, Changing the Display Function Between DP and HDMI
    The Jetson Orin SOM provides DP or HDMI functionality. The pinmux sheet contains the tab for DP and HDMI. Depending on their custom carrier board design, end users should generate the appropriate pinmux files. In addition to pinmux changes, the kernel display dtsi files need to be included in the carrier board kernel DT files, which contains DCB blob update to change between DP and HDMI Refer to Orin Display Configuration.)

hardware: please refer to design guide document.

software: you already mentioned the patch that is needed.
