HDMI

I want to bring up HDMI on custom board using jetson agx orin but unable…

I have taken the reference of tegra234-dcb-p3767-0000-hdmi.dts and added it into the tegra234-dcb-p3737-0000-p3701-0000.dtsi but still getting problem…

please refer to

Yes, I have already follows all the things…






This one also I have added in tegra234-p3737-0000+p3701-0000.dts

then please review your hardware design.

Did you cross verified that, everything is fine from software side?

yes, they look fine to me.

One doubt I have, that one is the previous node settings


and i have added these two lines in pcie@141a0000…so, is this correct?

this is not related to original topic. Please ask in another thread.

ok…


Once look into this, I have checked.. using minicom

using chatgpt…

4️⃣ Confirm Regulator Configuration

Inspect regulators using:

cat /sys/class/regulator/*/name
cat /sys/class/regulator/*/state

If 3.3V or 12V PCIe rails are disabled, the GPU won’t power on.

As per the Technical Documentation of Jetson agx orin for HDMI:

Display : 1x 8K60 multi-mode DP 1.4a (+MST)/eDP 1.4a/HDMI 2.1

but in our custom board Esd protection diodes are compatible for HDMI 2.0.

is this effects on working of HDMI ?

No, it does not matter. Actually HDMI2.1 is not supported on Orin software either.

Module datasheet is just hardware capability. You need to check L4T developer guide for actual software support.


What does, exactly means : The Jetson Orin HDMI passed the HDMI2.1 certificate with the GCTS2.1f version, and only the features in the table above are supported.

Just to clarify. We’ve been guiding lots of users how to enable HDMI2.0 in the past 3 years.
What you are asking is not the main problem/cause to your issue. If you follow the design guide, then with above software would make it work.

GCTS means HDMI 2.1 Cat 3 Cable Generic Compliance Test Specification (GCTS).





Can you please check this, it’s helpful for us.
Is there any correction we need here?

Hi,

Please directly refer to design guide document. We don’t do fully review to the schematic here.

If any specific questions, we can answer.

Even after flashing is successful, why this error is showing, even I didn’t create L4TConfiguration_updated.dts

Is there still “L4TConfiguration_updated.dts” under bootloader directory after flash? If so, what is the content of it?

It is not available in any folder…
