i have a issue to drive the AUO 1280x800 lvds screen, which color is always blue and the whole screen shifted to right by around 1 inch.
the development platform is Android 5.0 with patch from nxp. the processor is imx6ql.
i used to work on the hdmi screen, which worked perfectly.
i have made some changes on device tree and bootargs. non of them make the screen work correctly.
the following is the lvds channel 0 in the device tree.
lvds-channel@0 {
fsl,data-mapping = "spwg";
fsl,data-width = <18>;
crtc = "ipu1-di0";
primary;
status = "okay";
display-timings {
native-mode = <&timing0>;
timing0: auo101evn01 {
clock-frequency = <68272200>;
hactive = <1280>;
vactive = <800>;
hback-porch = <28>;
hfront-porch = <17>;
vback-porch = <13>;
vfront-porch = <20>;
hsync-len = <20>;
vsync-len = <13>;
/* de-active = <1>;
pixelclk-active = <0>;*/
};
};
