修改kernel源码文件夹中arch/arm/boot/dts/imx6qdl-sabresd.dtsi(此文件作为头文件被imx6q-sabresd.dts包含)中lvds接口显示配置如下：
&ldb {
status = "okay";
lvds-channel@0 {
fsl,data-mapping = "spwg";
fsl,data-width = <18>;
primary;
ipu_id = <1>;
disp_id = <0>;
status = "okay";
display-timings {
native-mode = <&timing0>;
timing0: hsd100pxn1 {
clock-frequency = <65000000>;
hactive = <1024>;
vactive = <768>;
hback-porch = <220>;
hfront-porch = <40>;
vback-porch = <21>;
vfront-porch = <7>;
hsync-len = <60>;
vsync-len = <10>;
};
};
};
lvds-channel@1 {
fsl,data-mapping = "spwg";
fsl,data-width = <18>;
/* primary; */
status = "okay";
display-timings {
native-mode = <&timing1>;
timing1: hsd100pxn1 {
clock-frequency = <65000000>;
hactive = <1024>;
vactive = <768>;
hback-porch = <220>;
hfront-porch = <40>;
vback-porch = <21>;
vfront-porch = <7>;
hsync-len = <60>;
vsync-len = <10>;
};
};
};
};
在源码文件夹生成dtb:
$make imx6q-sabresd.dtb
