Hi,

For rel-35, we have a existing patch over this post that you could apply.

HDMI Display does not work after update to JetPack 5.0.2

Hi, 麻煩先照這個步驟上patch, 做full flash. 這是有其他用戶已經驗證過的檔案. 另外, 麻煩對照一下flash log確認你燒進去的pinmux跟dtb真的是你改的那一份 因為市面上有多款Orin module. dtb跟pinmux檔案有可能不是你預期要改的那份 apply the [orin-hdmi-support-pinmux.patch] use the new hdmi dcb file '[tegra234-dcb-p3701-0000-a02-p3737-0000-a01-hdmi-4-ga5.0.2.dtsi] apply the kernel hdmi hotplug patch [0001-orin-hdmi-hotplug-support-kernel-dts.patch] rebuilt the kernel dtb and “reflash the image” //Note : make sure ‘reflash’ the image, no substitute dtb in exlinux!! 0001-orin-…

If even this one does not work for you, then it is hardware problem.
Please review with design guide document.
