SN65DSI86: [MIPI Bridge]The display is abnormal when the screen is on

Hi,

Can you share the PCB shcematic for review?

Hello Chen,

Some additional information that could help debug this issue is found in the e2e FAQ as a debugging guide, https://e2e.ti.com/support/interface-group/interface/f/interface-forum/990480/faq-sn65dsi84-how-to-debug-flickering-video-with-sn65dsi83-sn65dsi84-and-sn65dsi85. 

Thanks,

Zach

Hi Malik,

    The PCB shcematic has been saved in path "[display]display_error/data/ice Tea-MIPI Bridge.pdf" of onedrive, please help to review, thanks.

    Looking at the MP4 screen, I personally think it's a picture tear, maybe it's related to the Vsync signal?

Hi,

We will review and get back to you shortly. 

Thanks,

Zach

Hi,

Is the register value correct in [display]display_error/data/code.txt of OneDrive?

Or any debug suggestions?

Hey Chen,

First, please ensure that you are programming the DSI86 registers appropriately and according to your panel datasheet.

Please refer to the following E2E thread to understand how to program the registers:

https://e2e.ti.com/support/interface-group/interface/f/interface-forum/945404/faq-sn65dsi86-how-do-i-programming-the-sn65dsi86-registers

After you have ensured proper configuration of the DSI86 registers, follow the datasheet to enable the test pattern feature of this device.

Thanks,

Zach
