HDMI SS Tx Only Example Design

I hook up everything needed for ZCU102 and prepare the example design for HDMI SS

The passthru works pretty well. 

However, if switch to TX only colorbar, the monitor shows nothing

And the uart keeps looping Starting colorbar, Tx stream is down and Tx stream is up

Very rare it can show 1080p / 720p color, but never sucess for 4k

Any ideas?

@eerobert

Have you changed anything based on original example design? Which revison of ZCU102 board are you using? If not, please upload your xci file, I will try to reproduce the problem at my end.

Re: HDMI SS Tx Only Example Design

Hi, 

 

Thanks for your reply.

It seems like the Tx Only Example is working if the Monitor not going into the standby mode.

However, both monitor I have will go to standby mode before the HDMI Tx ready.

So it comes to a loop

1. Monitor detects HDMI signal

2. Monitor wait for valid HDMI signal

3. Monitor timeout and goes standby 

4. HPD deassert 

5. HDMI Tx SS reset the whole Tx pipe

6. Goto step 1

Re: HDMI SS Tx Only Example Design

Hi @eerobert

 

Would you share the following information ?

 

- Part number of Monitor

- Do you use authorized HDMI cable ? If possible, would you share it ? Especially, cable length, diameter and exist of cable filter.

 

Best regards,

Re: HDMI SS Tx Only Example Design

Hi @eerobert

As passthrough design works fine, I think the monitor and cable should be okay.

What's the revision of your ZCU102 board? When you test the TX only example design when monitor is standby, please type "i" and "z" in the terminal menu, and then attach this log information.

Also can you check if you see this problem with v2018.2 design, or v2018.3, or both?

Please attach the SDK workspace, and elaborate exact step (eg. TX cable is pluged after powering up the board, or before), I will use the exactly same file, and try to reproduce the problem at my end.

Quick reply

 

Just using 2018.1 example design, everything untouch and compile. Both passthru with 'c' command, or tx only design will have the same problem
