TDA4VE-Q1: TDA4VE DSS Multi-screen display failure

Hi Kong,

Please find answers to your questions below.

Question 1: If TDA4VE ENABLE_DSS_SINGLE is enabled and ENABLE_DSS_DSI output is selected, how can I specify the output to MPI DSI0 or MIPI DSI1?

SDK currently does not support DSI1. By default, it just outputs on DSI0. You would require to make changes in the SDK to support DSI1.

Question 2: Enable TDA4VE ENABLE_DSS_DUAL and see code. Only edp and hdmi output is supported in dual mode. How do I configure two cameras to output edp and mini dsi0/1 respectively?

Do you mean two different outputs on the displays from two different camera? Well this is possible, you can connect display pipeline to two different outputs, and then in the pipeline, you can select the camera output to be displayed..

Question 3: If TDA4VE ENABLE_DSS_DUAL is enabled, can dual-channel video output for mipi dsi0 and dsi1 cameras be supported separately?

that's possible, but requires changes in the SDK.

Question4: Can the TDA4VE support video output from edp, mini dsi0, and mini dsi1 cameras separately?

That's possible but requires changes in the SDK.

Question5: Can the TDA4VE support the video output of edp, mini dsi0, mini dsi1 and dpi cameras separately?

I think DPI is possible as long as pins are available for hte DPI.

Hi，

    We hope you can provide relevant reference patches, thank you!

Hi Kong,

Since it is not possible to validate DSI1 on the EVM, it is not supported in the SDK. You can follow support of DSI0 and add support for DSI1.

Btw, are you sure that you want DSI0 and DSI1 and not CSI0 and CSI1 ? This is because DSI output goes via DSS, so it will use DSS pipeline to read the paths.

Hi Kong,

As i mentioned, DSI1 is not currently supported in the SDK. Are you sure that the MAX96717 serializer supports DSI? Because as far as i know, it supports CSI/MIPI protocol and not DSI protocol. If you are looking for CSITX1, then that can be supported.
