Imx6q g150xge-l04 display colors problem

Hello,

I have G150xge-l04 display connected to the first lvds channel.

When I configured dtsi file, system starts up but the problem occurs with colors.

The system has set 32 bits per pixel but when i look on that display it display only 256 colors.

Below there is a ldb configuration:

&ldb {

       status = "okay";

       lvds-channel@0 {

             fsl,data-mapping = "spwg";

             fsl,data-width = <24>;

             status = "okay";

             primary;

             display-timings {

                    native-mode = <&timing0>;

                    timing0: hsd100pxn1 {

                           clock-frequency = <65000000>;

                           hactive = <1024>;

                           vactive = <768>;

                           hback-porch = <40>;

                           hfront-porch = <40>;

                           vback-porch = <5>;

                           vfront-porch = <5>;

                           hsync-len = <136>;

                           vsync-len = <6>;

                           vsync-active = <0>;

                           hsync-active = <0>;

                           interlanced = <0>;

                           doublescan = <0>;

                    };

             };

       };

What can be misconfigured ?

I have 10,4" display with the same configuration and there is no problem with colors on display.

Grettings,

Maciej

Hi Macijei

could you try to use kernel boot parameters, like if=RGB24 described in

iMX6QD How to Add 24-bit LVDS Support in Android

also what BSP used in the case, could you try with latest

Board Support Packages (35)

L4.1.15_1.0.0_MX6QDLSOLO (REV L4.1.15_1.0.0)

Best regards

igor
