thanks but now my uboot have bmp function but get the error on start u-boot what is that error mean. is the format of original /boot/boot.bmp have problem or problem is another thing.
for now how we can change kernel boot logo. is there any way to change it.
on other problem I have is I use usb-otg of orange pi lite as default sub and use it to run HDMI LCD. but because power delay LCD resolution by kernel isn't correct and i don't see kernel-logo on center. can I set default resolution in kernel before compile it.
