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

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,

},

非常感谢您的回复！

kernel中打开gpu导致系统启动失败是由于，我们没有使用电源管理的芯片，dts中跟gpu、vpu相关的电压设置采用了原来的导致的。将相应的pu-supply = ;全部设置成，就OK了，ldb显示也OK了。主要对dts中很多参数不理解。

So, have you try mode_str ="BT101IW01" ?

Thank you for your suggestion。

In Android4.2.2，“BT101IW01"  is wrote in "kernel_imx/arch/arm/boot/dts/imx6qdl-sabresd.dtsi".But in Android4.4.3, I have no write in dts.

Now,I modify "arch/arm/boot/dts/imx6qdl-sabresd.dtsi", as follows:

&ldb {

status = "okay";

lvds-channel@0 {

fsl,data-mapping = "spwg";

fsl,data-width = <18>;

status = "okay";

display-timings {

native-mode = ;

timing0: hsd100pxn1 {

clock-frequency = <48653926>;

hactive = <1024>;

vactive = <600>;

hback-porch = <220>;

hfront-porch = <40>;

vback-porch = <21>;

vfront-porch = <7>;

hsync-len = <60>;

vsync-len = <10>;

};

};

};

when boot in kernel,I can see the two Penguin .Then boot android,I can see "Android_" a little while。(android启动时我可以看到android字体几秒，然后就无显示了)

The logcat as follow:
