How to enable HDMI Display Instead of DP

Hi,
Our customized carrier board for Orin AGX has HDMI display instead of a display port.
What should I change in the device tree to accomplish this task?
Is there any valid reference for the steps that comply with the latest jetpack 6?

  1. Please open p3509-a02-p3767-0000.conf and there are four fields.
 31 PINMUX_CONFIG="tegra234-mb1-bct-pinmux-p3767-hdmi-a03.dtsi";
 32 PMC_CONFIG="tegra234-mb1-bct-padvoltage-p3767-hdmi-a03.dtsi";
 33 OVERLAY_DTB_FILE+=",tegra234-dcb-p3767-0000-hdmi.dtbo";
 34 DCE_OVERLAY_DTB_FILE="tegra234-dcb-p3767-0000-hdmi.dtbo";

Please port them to your Orin AGX board config. (The above are original Orin NX configuraiton)

  1. Please add os_gpio_hotplug_a = <&gpio TEGRA234_MAIN_GPIO(M, 0) GPIO_ACTIVE_HIGH>; to the display node display@13800000 in the device tree and do ful flash.

Hi,
Thank’s for the reply.
Is there any example for Orin AGX and not NX ?
