Hi kaycc，

I want to enable HDMI on Custom Carrier Boards , I foun it‘s not working follow this steps:

======================================
Enabling HDMI on Custom Carrier Boards

This information is specific for modifying the device tree file for your custom carrier board and does not apply when you use the Developer Kit carrier board.

  1. Download the example HDMI DTS file

    Download the 鈥渢egra234-dcb-p3701-0000-a02-p3737-0000-a01_hdmi.dtsi鈥� file from Jetson Linux 34.1.1 | NVIDIA Developer

  2. Modify kernel dts with HDMI connector support

    The JetPack5.0-DP release Kernel sources includes a dtsi file that sets DCB with DP connector support by default. Users will need to update the provided dtsi file with the downloaded dtsi file to enable HDMI setting.

    Path: <Kernel_Sources>/hardware/nvidia/platform/t23x/concord/kernel-dts/

  3. Modify your board dts to replace the default DCB dtsi:

— a/tegra234-p3701-0000-p3737-0000.dts
+++ b/tegra234-p3701-0000-p3737-0000.dts

#include “cvb/tegra234-p3737-camera-modules.dtsi”
Recompile the Kernel by completing instructions in Kernel Customization .

  1. Reflash your board with the updated Kernel and Kernel DTB

Are there any other parts of the device tree that need to be modified?
