Is the resolution in U-boot the same as the resolution of your screen?

splash image size is 800600
actual VGA screen resolution is 1152


splash image size is 800*600

actual VGA screen resolution is 1152*864


I would test the uboot resolution, I would change it to your screen resolution and see if the problem persists


i dont want any u-boot splash.
i want splash on LVDS LCD

So it’s the Linux splash?

If it is, is your vidargs variable correct?

its is linux splash.

i have set below vidargs variable for VGA
setenv vidargs ‘video=mxcfb0:dev=vdac,1024x768M@60,if=RGB565 video=mxcbf1:off video=mxcbf2:off video=mxcbf3:off fbmem=32M’

setenv vidargs ‘video=mxcfb0:dev=ldb,800x600,if=RGB888,video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off fbmem=32M’
