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
