使用AM335X板子,移植uboot lcd驱动后,目前开机uboot阶段正常显示我的logo,由于我的kernel和uboot使用的是同一张图片,到了kernel启动时,现象就是这个logo会闪一下,像是被重置了一下,请问这是什么导致的?该如何解决?

uboot logo阶段:根据StarterWare里面的lcd驱动进行移植,然后显示正常
kernel logo阶段:修改drivers/video/logo/logo_linux_clut224.ppm,重新编译,烧录,显示正常
注:我的uboot和kernel两个阶段显示同一张图
所以问题来了:每次在Starting kernel ...的时候会闪一下,像是重置了某个地方?
