B-LCD40-DSI1 DSI Data Lane Setting

[ELee.9]

Hi, I'm working on a project using DSI to print LCD with STM32F769I-Eval.

In this kit, there is a display module called B-LCD40-DSI1, and it has a OTM8009A.

I build an example called LCD_DSI_CMDmode_SingleBuffer, and it worked.

But after I changed numberOfLanes value to one and activate LP Mode only, It printed LCD display well, but its refresh rate was so slow.

So I want to use High Speed Transmission, but It didn't work.

Can I use B-LCD40-DSI1 with one data lane?
