Hi Rayson,

You also have to modify the BSP after you have completed configuring the LCD Parameter refer to the LCD datasheet.

Here you can refer to this thread:

LCD not working on custom i.mx6q board

There are details in how to modify, you can have a refer to.

Besides, here I attach you two documents, they are useful for you.
Have a great day
Dan

struct fb_videomode {

const char *name; /* optional */

u32 refresh;  /* optional */

u32 xres;

u32 yres;

u32 pixclock;

u32 left_margin;

u32 right_margin;

u32 upper_margin;

u32 lower_margin;

u32 hsync_len;

u32 vsync_len;

u32 sync;

u32 vmode;

u32 flag;

};

Hi Rayson

You need to contact local supplier for datasheet.

It you still can't find it than you should try standard WSVGA parameter. It should work.

Thanks

Hi

Rayson

You can try this.

static struct fb_videomode video_modes[] = {

     ...

     {

         .name = "WSVGA",

         .refresh = 60,

         .xres = 1024,

         .yres = 600,

         .pixclock = 48000,

         .left_margin = 104,

         .right_margin = 43,

         .upper_margin = 24,

         .lower_margin = 20,

         .hsync_len = 5,

         .vsync_len = 5,

         .sync = 0,

         .vmode = FB_VMODE_NONINTERLACED,

         .flag = 0,

    },
