ZCU106 HDMI DP

Jump to solution

 I have three questions!

 

1.When i use ZCU106 and rdf0428-zcu106-vcu-trd-2018-2 images, when the petalinux run it up, i enter "modetest -M xlnx", only DP message appears, not any HDMI messages. How I Can get HDMI messgaes, like plane ID, CRCT ID, and so on.

 

2.When i use ZCU106, I plug both HDMI and DP cable, HDMI is unable to appear blue background. HDMI and DP cannot work both?

 

3.How i can insert my picture into mixer(or kmssink in gstreamer) in DRM framework? Is there any examples?

 

Thanks!

Thanks for your response!

 

 I solve the first and  the third questions.

 1. use 'modetest -D a0070000.v_mix' can display HDMI related informations.

 3. I use gstreamer methods to read a png file from SD card and link it to DRM device,

 [Florent] - Are you using a HDMI monitor (no adapters). No sure if DP and HDMI can be used at the time in this demo. What do you get if you only plug the HDMI cable?

 

2.When i use ZCU106, I plug both HDMI and DP cable, HDMI is unable to appear blue background. HDMI and DP cannot work both?

[Florent] - I am not sure if both can work at the same time in this demo. But this would be only a limitation of the demo.

 

3.How i can insert my picture into mixer(or kmssink in gstreamer) in DRM framework? Is there any examples?

[Florent] - You need to check if the demo implement a Soft pattern generator. This means that the image is stored in memory. I believe there is one is this demo. You just need to replace the image in memory

 

Thanks!

But the second question i can't solved it !

 

I can use DP and HDMI seperately, but cann't both plug a monitor before power up. If i do this, the HDMI monitor wil show nothing.

 

What I can do to solve this problem? Is a bug for ZCU106 Demo or Board?

HI @lixiaolin126,

 

Not sure what you can do. In my opinion, this is only a limitation of the demo. You should be able to launch script files at the beginning to launch the HDMI

 

Thank you for sharing your answers to the 2 other questions

Hi @lixiaolin126,

 

There is a known issue with some ZCU106. Make sure the DP159 on the board is not an ES chip.

 

Refer to AR#70515 for detail

 

Hope that helps,

HI @lixiaolin126,

 

No it is not the reason why you cannot use both HDMI and DP. I am quite sure you need to modify the application for this.

 

how i can check the chip is ES or not?
