RK3128 点LVDS过程

 

1、进入dts目录

rk\rk312844\rk3128_android4.4\kernel\arch\arm\boot\dts

 

2、打开修改dts

默认是HDMI输出 配置文件为LCD-BOX.dtsi

注释LCD-BOX.dtsi

增加LCD-b101ew05.dtsi

3、增加dtsi

                disp_timings: display-timings {

                        native-mode = <&timing0>;

                        timing0: timing0 {

                                screen-type =;

                                lvds-format =;

                                out-face    =;

                                color-mode =;

                                clock-frequency =<71000000>;

                                hactive =<1280>;

                                vactive =<800>;

                                hback-porch =<100>;

                                hfront-porch =<18>;

                                vback-porch =<8>;

                                vfront-porch =<6>;

                                hsync-len =<10>;

                                vsync-len =<2>;

                                hsync-active =<0>;

                                vsync-active =<0>;

                                de-active =<0>;

                                pixelclk-active =<0>;

                                swap-rb =<0>;

                                swap-rg =<0>;

                                swap-gb =<0>;

这里填上屏的参数

 

4、编译kernel

5、烧录kernel

这个时候应该有显示了
