DS90UH948-Q1EVM: No pattern generator output

Hello,

I am trying to get the DS90UH948-Q1EVM pattern generator to output to a display, but there is no visible output. I've followed the setup parameters outlined by the user guide. I've tried the same actions on the DS90UH949-Q1EVM with no luck either. I've attached pictures of both boards and my setup when connected to the 948.

Hi Bruce,

Thank you for all the supporting material you've provided related to this issue.

I would like to confirm a couple of items:

The 948 is attempting to send a pattern generation to the 949 which then sends it to a monitor connected via HDMI, which shows no output nor activity after clicking "Apply" under Video Control?

And that you have already attempted the following:

- Changing the pattern under Pattern Generator Control V2 and applying,

- Enabling the Generator and color bar checkboxes and applying?

Please do let me know the results of these actions and my understanding of the situation, as I look into verifying these settings myself.

Best,

Miguel

There was an additional wiring issue with the display that was causing the issue, thanks for the help!
