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

  1. apply the [orin-hdmi-support-pinmux.patch]
  2. use the new hdmi dcb file '[tegra234-dcb-p3701-0000-a02-p3737-0000-a01-hdmi-4-ga5.0.2.dtsi]
  3. apply the kernel hdmi hotplug patch [0001-orin-hdmi-hotplug-support-kernel-dts.patch]
  4. rebuilt the kernel dtb and “reflash the image” //Note : make sure ‘reflash’ the image, no substitute dtb in exlinux!!

Please follow above instructions to apply patch to your pinmux and device tree first. Also, make sure the one that got flashed are really the files you flash to the board. There are multiple kinds of orin module in the market so it has multiple dtb and pinmux files too.
