Dear All,

I met the LVDS display displacement on Yocto 3.2 source code.

Is there anyone know what should I check?

 

DTS:

ti,dsi-lanes = <4>;
ti,lvds-format = <2>;
ti,lvds-bpp = <24>;
ti,width-mm = <149>;
ti,height-mm = <93>;
ti,lvds-channels = <1>;

lvds {
clock-frequency = <74250000>;
hactive = <1280>;
vactive = <800>;
hback-porch = <6>;
hfront-porch = <95>;
vback-porch = <1>;
vfront-porch = <80>;
hsync-len = <1>;
vsync-len = <1>;
hsync-active = <0>;
vsync-active = <0>;
de-active = <1>;
pixelclk-active = <0>;
};

Hi Jarvis

 

one can try imx8qm-mek-jdi-wuxga-lvds1-panel.dtsi

https://source.codeaurora.org/external/imx/linux-imx/tree/arch/arm64/boot/dts/freescale/imx8qm-mek-j...

and add custom timings to struct display_timing jdi_tx26d202vm0bwa_timing in panel-simple.c

https://source.codeaurora.org/external/imx/linux-imx/tree/drivers/gpu/drm/panel/panel-simple.c?h=lf-...
