Display Timing

Hi Sarathi,

You should set the timings directly in the dts file. Which dts file are you using? Also which SDK version?

Assuming you use am437x-gp-evm.dts, you should modify the following dts node with the timings needed for your use case:

  lcd0: display {

           compatible = "osddisplays,osd057T0559-34ts", "panel-dpi";

           label = "lcd";

           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>;

           };

           port {

                    lcd_in: endpoint {

                                  remote-endpoint = <&dpi_out>;

                    };

           };

};
