烧写的镜像为飞凌提供的镜像C:\Users\Lenovo\Desktop\11111111.png

djh

看打印信息U盘存在无效分区，建议重新格式化一下再拷贝镜像进行烧写；或者换个一个其他U盘进行烧写
U盘大小要大于4G，格式为FAT32格式

多谢，换了一个U盘就可以烧写了。
还有一个问题请教一下，U盘只烧写Image镜像，怎么实现？  不烧写ubuntu.img，

单步更新内核：
可以使用 U 盘直接替换文件系统中/run/media/mmcblk0p2/boot/的镜像。
使用如下命令替换镜像：
cp -rf /run/media/sda1/boot /run/media/mmcblk0p2/
然后再输入 sync 保存 重启即可。
