最近在开发imx6ul,发现LCD的工作模式是DE模式 ,不是我们常规的HV模式。LCD虽然可以显示,但是对于之前使用的VGA芯片是不能正常工作。各位大神,有谁知道如何修改LCD的模式,修改成HV模式?不胜感激!

Hi shi

in imx6 .dts file remove:

hsync-active = <0>;

vsync-active = <0>;

de-active = <1>

and set correct hsync,vsync timings in "display-timings", as for example below:

https://github.com/boundarydevices/linux-imx6/blob/boundary-imx_3.14.28_1.0.0_ga/arch/arm/boot/dts/i...

Best regards

igor
