Hi,igor

Thanks for your reply, I download the U-BOOT source code and find the fb.h in /include/linux folder. I find the definition of struct fb_videomode in fb.h, so what my question is I should modify it there like the following:

struct fb_videomode {

const char *name = XXX; /* optional */

u32 refresh = XXX; /* optional */

u32 xres = XXX;

u32 yres = XXX;

u32 pixclock = XXX;

u32 left_margin = XXX;

u32 right_margin = XXX;

u32 upper_margin = XXX;

u32 lower_margin = XXX;

u32 hsync_len = XXX;

u32 vsync_len = XXX;

u32 sync = XXX;

u32 vmode = XXX;

u32 flag = XXX;

};

as you see, I add "= XXX", i am not sure if i should add these parameters there, so pls tell me if it is correct, or tell which file should be modified. looking forward to reply, thanks.

Best Regards,
