Dual Channel interface with IMX6Q

prateek22 — Wed, 08 May 2024 06:18:20 GMT

Hi,

I am trying to interface dual channel LVDS with imx6 board kernel 3.0.35 which doesn't support device tree concept.

There is board config file which needed to be modifies to drive dual channel LVDS for 1920x1080@60 resolution.

Could you please let me know what changes are required to drive dual channel LVDS display with resolution 1920x1080 with 60Hz refresh rate.

Thanks,

Prateek

if you need to use higher resolution, try to use split mode, and don't forget add your lvds timings in the bsp, for more detailed information, pls refer to the Chapter 7 LVDS Display Bridge(LDB) Driver of enclosed file

Thanks Joanxie, as per your reply I have update LVDS to split mode as you can observe in below screenshot:

As well as updated clock w.r.t new display datasheet as below:

As well update u-boot to run LDB-1080P60 for full HD (1920x1080) with 60Hz refresh rate.

Let me know any other changes required.

Thanks,
