LVDS屏幕只有背光如何解决

ti

问：LVDS屏幕uboot和kernel都没显示,只有背光

答：run load_scr; source;
setenv disp_fb0_lvds1 "video=mxcfb0:dev=ldb,LDB-WXGA,if=RGB666 ldb=sin1"
setenv display "${disp_fb0_lvds1}"
saveenv; boot
烧录后环境变量设置

问：我这个屏的参数U-BOOT班级文件配置：
      .bus = -1,
      .addr = 0,
      .pixfmt = IPU_PIX_FMT_RGB666,
      .detect = NULL,
      .enable = enable_lvds,
      .mode = {
            .name          = "MYZR-WSVGA",
            .refresh       = 60,
            .xres          = 1280,
            .yres          = 800,
            .pixclock    = 14507,
            .left_margin = 34,
            .right_margin = 34,
            .upper_margin = 3,
            .lower_margin = 3,
            .hsync_len    = 60,
            .vsync_len    = 10,
            .sync          = FB_SYNC_EXT,
            .vmode       = FB_VMODE_NONINTERLACED

设备树文件配置：
lvds-channel@0 {
            fsl,data-mapping = "spwg";
            fsl,data-width = <18>;
            status = "okay";

            display-timings {
                     native-mode = <&timing0>;
                     timing0: hsd100pxn1 {
                              clock-frequency = <68930000>;
                              hactive = <1280>;
                              vactive = <800>;
                              hback-porch = <34>;
                              hfront-porch = <34>;
                              vback-porch = <3>;
                              vfront-porch = <3>;
                              hsync-len = <60>;
                              vsync-len = <10>;
                     };
            };
      };
屏的参数先不改了吗？
