Hdmi display with snowflake

hi, nvteam

I flash the orin module with jetpack5.0.2GA. and I make a change about the display from DP to HDMI. because on our custom board we have hdmi. I follow the instruction below(use dcbtool)

https://docs.nvidia.com/jetson/archives/r35.1/DeveloperGuide/text/SD/Kernel/DisplayConfigurationAndBringUp/OrinDisplayconfig.html

the hdmi can work, but it has snowflake.

so any suggestion about this problem ?

Looks like hardware issue. And may need to do the HDMI tuning.

We will check when the document would be released.

some update about this , when we log in the sysytem we find the color looks wrong. for example the firefox icon looks below, how to fix it?

Please find the Jetson AGX Orin Series Tuning and Compliance Guide Application Note from Jetson Download Center | NVIDIA Developer

ok, we will try

another question : for the jetpack5.0.2, to enable custom board HDMI.

I should use method below

https://docs.nvidia.com/jetson/archives/r35.1/DeveloperGuide/text/SD/Kernel/DisplayConfigurationAndBringUp/OrinDisplayconfig.html

instead of method

https://docs.nvidia.com/jetson/archives/r34.1/DeveloperGuide/text/SD/Kernel/DisplayConfigurationAndBringUp.html

right?

yes.

we fix it. it is a hardware question. we make a mistake about lane0 and lane2.

thank you all
