LCDIF and Host Display controller support in U-boot for i.MX8M Mini

[kailas_kharse]

Hello,

I am in process of porting the LCD with the MIPI interface in U-boot, Display works properly in Kernel.

I want to understand that do we have the support of LCDIF and Host display controller in U-boot?

How can I port the MIPI-Display in U-boot? Do you have any working reference to port MIPI-Display in U-boot?

Thanks & Regards,
Kailas K

Hi Kailas

one can look at below example (for RM67191), for custom lcd timings can be added to

struct display_info_t const displays[]

#ifdef CONFIG_VIDEO in

Best regards

Hello Igor,

We already have tried adding the structure and enabled the CONFIG_VIDEO in defconfig and also instead of adding

CONFIG_VIDEO_MXS=y
CONFIG_RM67191=y

no rm67191.o is getting generated. I think we are missing something can you share all the configs and dts for imx8mm and anything else that will be required to get the panel up.


Thanks & Regards
