RK3288 Android7.1 LVDS调试问题

作者:互联网

最近在rk平台上调试一款32寸的LVDS,屏是1920*1080分辨率,双路8bit RGB888 格式的屏,在rk3288-evb-android-rk808-lvds.dts下面的lvds修改如下,编译烧录进去屏幕一直循环播放红绿蓝图片。
请大侠们分析分析,屏的规格书我也上传一份。

&lvds_panel {
status = “okay”;
compatible =“simple-panel”;
//backlight = <&backlight>;
bus-format = <MEDIA_BUS_FMT_RGB888_1X24>;
power-supply = <&vcc_lcd>;
delay,disable = <10>;
enable-gpios = <&gpio7 4 GPIO_ACTIVE_HIGH>;
//rockchip,data-mapping = “jeida”;
rockchip,data-mapping = “vesa”;
rockchip,data-width = <24>;
rockchip,output = “duallvds”;

display-timings {
    native-mode = <&timing0>;
    timing0: timing0 {
            clock-frequency = <148000000>;
            hactive = <1920>;             /* Horizontal display area thd 1024       DCLK            */
            vactive = <1080>;             /* Vertical display area tvd   600        H               */
            hback-porch = <48>;           /* HS Width +Back Porch   160  160   160  DCLK (Thw+ thbp)*/
            hfront-porch = <60>;          /* HS front porch thfp    16   160   216  DCLK            */
            vback-porch = <8>;            /* VS front porch tvfp    1    12    127  H               */
            vfront-porch = <33>;       /* VS Width+Back Porch    23   23    23   H (Tvw+ tvbp)   */
            hsync-len = <32>;             /* HS Pulse Width thw     1     -    140  DCLK            */
            vsync-len = <4>;              /* VS Pulse Width tvw     1     -     20  H               */
            hsync-active = <0>;
            vsync-active = <0>;
            de-active = <0>;
            pixelclk-active = <0>;
    };
};

};
