Hi there

I have a AUO display (G065VN01) that is 640x480 6inch which I need to enable in our Linux kernel. 

I've used in my devicetree the parameters from the datasheet (http://www.datadisplay-group.com/fileadmin/pdf/produkte/Displays/AUO/G065VN01V2_Datasheet.pdf ) without any real luck. The display is just blinking red,blue, black and white every now and then. No image is being formed on the screen. 

The section in the device tree is as follows:

 

&ldb {
    status = "okay";

      lvds-channel@0 {
         crtc = "ipu1-di1";
         fsl,data-mapping = "spwg";
         fsl,data-width = <18>;
         status = "okay";
         primary;

         display-timings {

            t_lvds: t_lvds_default {
               clock-frequency = <25200000>;
               hactive = <640>;
               vactive = <480>;
               hback-porch = <10>;
               hfront-porch = <10>;
               hsync-len = <130 160 430>;
               vback-porch = <100>;
               vfront-porch = <10>;
               vsync-len = <40 45 142>;
               hsync-active = <0>;
               vsync-active = <0>;
               de-active = <1>;
               pixelclk-active = <0>;
         };

      };

   };

};

 

The kernel I'm using is 3.14.38 but I've also tried the 4.1.33. 

 

If I use an older Toshiba display (LTA065B0D2F) that at least forms an image on the screen with these settings, even though they do not apply for that display. So far I haven't been able to have any image forming on the AUO display, just this blinking as described above. 

 

Anybody dealing with this issue or know how to solve ?

 

regards

Einar
