DS90UH983-Q1: generate a test pattern from DS90UH983-Q1 to DS90UH984-Q1

Tool/software:

Hello,

We tried to generate a test pattern from DS90UH983-Q1 to DS90UH984-Q1.

And then output DP data to a panel from 984. But we can't see any image on the screen.

When I checked the register of 984, it seems that no image signal was received. I'm not sure whether 983 didn't send the image or 984 didn't receive it correctly.

Are there any registers in 983 and 984 that could help clarify this issue? Thanks.

Thank you in advanced.

Best Regards,

    Hi Jack!

    Would you please share your initialization script for the 983 and 984 to check the configurations?

    The 983 and the 984 have APB registers and interrupts that can help evaluate DP related error diagnostics, these can be read using scripts.

    Since these scripts are quite involved and mostly NDA, could you please inform me if you are able to get in touch with an FAE to make this an internal E2E forum?

    • If this is not possible, and if you do not wish to share the initialization script in the forum, you may also reach me at m-bolante@ti.com (Please include subject header DS90UH983-Q1: generate a test pattern from DS90UH983-Q1 to DS90UH984-Q1)

    Thanks!

    Hi Miguel,

    We already found out that we have some trouble with our cable.

    Thank you for your reply.
