只能用这个版本的吗？
如果要用新的uboot怎么改的
Coolpi 4b support dynamic update logo
-
Sometimes we may need to customize the logo display. We just need to copy logo bmp files to first partition of tf-card or emmc. Two logo files can be the same.
It should be noted that uboot must be upgraded to the latest.

到底能不能成功?
我刷了几台 就一台成功 -
@jugg 看日志已经刷好了，你在系统中把logo.bmp logo_kernel.bmp拷贝到/boot/firmware/，再重启
