How to update new display parameters

Postby Shuki.Z » Thu Apr 16, 2015 8:30 am

Hi,

The arch/arm/boot/dts/var-som-am33.dts defines the hardware of VAR-SOM-AM33.
Navigate to the display-timings section:
display-timings {
800x480 {
hactive = <800>;
vactive = <480>;
hback-porch = <39>;
hfront-porch = <39>;
hsync-len = <47>;
vback-porch = <29>;
vfront-porch = <13>;
vsync-len = <2>;
clock-frequency = <30000000>;
hsync-active = <1>;
vsync-active = <1>;
};
};

- In your Linux folder you can find a document which describes the display parameters.
Documentation/devicetree/bindings/video/display-timing.txt.

- Please follow the Wiki for instructions for compiling the device tree file and updating the var-som-am33.dtb in your rootfs.

Regards,
Shuki
