Can G1120B0MIPI use DPI-2 interface(RGB interface) mode with MIMXRT595-EVK?

I have MIMXRT595-EVK and G1120B0MIPI board.

And I runned sd_jepg demo successfully.

When I traced the internal logic further, I found that the code uses APB interface but not DPI-2 interface(also called RGB interface)[It uses VSYNC, HSYNC, DOTCLK and ENABLE signals to transmit data to LCD panel.].

But APB interface only can transfer 255 bytes per time, just as below:

I want to change APB interface to DPI-2 interface(RGB interface) as below:

Does G1120B0MIPI support DPI-2 interface(RGB interface) mode?

Are there any relevant documents or routines that can be provided for reference?

Looking forward to your reply. Thanks.

Hello,

 

The RT595 does not support DPI-2, sorry, you may check with i.MX8M for this.

hi,

I read AN13509-Analysis of screen pushing scene based on i.MXRT595 MIPI DSI Controller, which shows it support DPI-2 as below:

Do I missed something? Thanks...

Hello,

I mean we do not have any code for DPI-2.

Thanks for your reply.

I find evkmimxrt595_lcdif_rgb565 example use lcdif(dpi)+dsi with 2 lane. It works fine.

But when I modify 2 lane to 1 lane.

The parameter not same between setting and captured:

The images shows  abnormal as below:

Should I also change clk or something else?

 

Thanks.
