Orin nx dp enable fail

I re-flashed the system after modifying the configuration, but there is still no output from the display port (DP).
Let me summarize the changes I have made:
First, adjust the pinmux configuration according to the Jetson_Orin_NX_series_and_Orin_Nano_series_Pinmux_Config_Template.xlsm. After the adjustment, use the Jetson_Orin_NX_Series_+HDMI A03 configuration, which has already been modified for the dp (display port).
Replace the generated dtsi file to Linux_for_Tegra/bootloader/t186ref/BCT/tegra234-mb1-bct-pinmux-p3767-hdmi-a03.dtsi.

Then adjust the dcb parameters. The adjustment file is located at: Linux_for_Tegra\sources\hardware\nvidia\platform\t23x\concord\kernel-dts\tegra234-dcb-p3701-0000-a02-p3737-0000-a01.dtsi.

refer to the following website:

Meanwhile, according to the problem you mentioned earlier, you have deleted the HDMI plug-and-play detection pin in the following file: Linux_for_Tegra\source\public\hardware\nvidia\platform\t23x\p3768\kernel-dts\cvb\tegra234-p3509-a02.dtsi.

Finally, the system was recompiled and fully flashed using the command:
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_external.xml -p “-c bootloader/t186ref/cfg/flash_t234_qspi.xml” --showlogs --network usb0 p3509-a02+p3767-0000 internal

However, the DP still does not display any output. Did I miss any steps, or is there something wrong with the previous configuration? The DP hardware should not have any issues because it can output DP signals using our own designed carrier board with the Xavier NX core board.

I have been debugging for many days and have been stuck in this place. I hope you can help me solve the problem. Thank you very much.
