急！！！！！！好几天了，求指教！
我们板子参照sabresd设计的。之前使用系统android4.2.2，现在移植官网BSP android4.4.3
目前surfaceflinger导致系统启动失败。一直打印如下红色显示的信息。

由于新内核使用dts。我跟Android4.2.2的内核相比较如下：
1、4.4.3时，使用LVDS接口，不知道是不是这么配置就可以了？？？？
①kernel_imx/arch/arm/boot/dts/imx6qdl-sabresd.dtsi
mxcfb1: fb@0 {
compatible = "fsl,mxc_sdc_fb";
disp_dev = "ldb";
interface_pix_fmt = "RGB666";
mode_str ="1024x600M@60";
default_bpp = <32>;
int_clk = <0>;
late_init = <0>;
status = "okay";
};
2、4.2.2时，我们使用LVDS接口，值修改添加了两个文件，是OK的。
①kernel_imx/drivers/video/mxc/ldb.c
· 在ldb.c文件中staticstruct fb_videomode ldb_modedb[]数组中添加lvds参数，如下 { "BT101IW01", 60, 1024, 600, 21553, 62, 62, 13, 13, 62, 12, 0, FB_VMODE_NONINTERLACED, FB_MODE_IS_DETAILED, },
②kernel_imx/arch/arm/mach-mx6/board-mx6q_sabresd.c 在board-mx6q_sabresd.c文件中添加BT101IW01模式，如下： { /*fb0*/ .disp_dev = "ldb", .interface_pix_fmt = IPU_PIX_FMT_RGB666, .mode_str = "BT101IW01", .default_bpp = 32, .int_clk = false, .late_init = false, },
