i.MX8 MIPI DSI to LVDS display issue

Processor: i.MX8mq

OS: Yocto (Linux L4.9.51 for i.MX 8MQuad Beta) & Android (Android O8.0.0 for i.MX 8MQuad Beta)


We use Ti SN65DSI83 to transform MIPI DSI signal to LVDS display.

When we turn on SN65DSI83 test pattern mode, we can see test pattern shown on the panel.

But when we turn off SN65DSI83 test pattern mode, we will see LVDS panel will repeat showing red, green, blue, black, white, checkerboard, grey.


Will i.MX8 MIPI DSI generate some test pattern by default?

What is the expected behavior on the panel?




PS: Attach the video of the display.
