How to update new display parameters

Postby Shuki.Z » Thu Apr 16, 2015 8:34 am

Hi,

The arch/arm/boot/dts/var-som-am43.dtsi defines the hardware of VAR-SOM-AM43.

Navigate to the panel-timing section:
panel-timing {
clock-frequency = <33000000>;
hactive = <800>;
vactive = <480>;
hfront-porch = <210>;
hback-porch = <16>;
hsync-len = <30>;
vback-porch = <10>;
vfront-porch = <22>;
vsync-len = <13>;
hsync-active = <0>;
vsync-active = <0>;
de-active = <1>;
pixelclk-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 your var-som-am43.dtb

Regards,
Shuki
