DS90UB948-Q1: Ds90ub948-q1: When DS90UB947-Q1 is used in combination with DS90UB948-Q1, the display screen has no content display

Ds90ub947-q1 is used with DS90UB948-Q1, the pattern test is performed, and the screen is not displayed.

Perform the configuration according to 4.4 Cases in the SNLA132G document. Use the Without FPD-link III scheme and configure 948 to enter Pattern test. The screen displays no information and is backlit.

How should I judge the problem? Please give me a reply. Thank you very much

To clarify, do you try to getting patgen to work on just the deserializer first before using patgen over the FPD-Link?

Could you share the script of the patgen registers setting? Also, please provide the specs for the display they are using as well.
