Thanks for you reply, Rupesh
I tried
video=omapfb:mode:640x...@60
video=omapfb:mode:800x...@60
video=omapfb:mode:1024x...@60
video=omapfb:mode:1280x...@60
but all failed.
My LCD is Dell 1907FPC, it should support all kinds of video mode I
think.
I review lcd_omap3beagle.c, it seems the vide mode is hard code. it
can be change only by building environment.
struct lcd_panel omap3beagle_panel = {
.name = "omap3beagle",
.config = OMAP_LCDC_PANEL_TFT,
.bpp = 16,
.data_lines = 24,

.hfp = 3, /* right_margin (4) - 1 */
.hbp = 39, /* left_margin (40) - 1 */
.vsw = 1, /* vsync_len (2) - 1 */
.vfp = 2, /* lower_margin */
.vbp = 7, /* upper_margin (8) - 1 */
.pixel_clock = LCD_PIXCLOCK,
#endif
#if defined CONFIG_FB_OMAP_031M3R
/* 640 x 480 @ 60 Hz Reduced blanking VESA CVT 0.31M3-R */

.hfp = 48,
.hsw = 32,

#endif

Please give me further info, thanks.
