我现在知道我不应该触摸启动分区。 我现在明白，只是我重建了一个rootfs，但它有点迟了。 我想知道我是否仍然可以使用备份恢复启动分区。
如果你有信息要给我，我会很高兴，因为此刻我的脚在混凝土中。 我开始使用Buildroot重建内核和rootfs，但我只是重建rootfs，因为我肯定会对驱动程序和内核配置非常恼火。 我没有关于原始编译选项的信息。
简而言之，你了解我的ambarras。 所以如果你有想法或研究方向，我会听你的。
谢谢
当我接触系统时，我使用DD命令进行备份：
dd if=/dev/mtdblock1 of=/mnt/nfs/mtdblock1 bs=65536
备份文件：
binwalk mtdblock1

答案 1 :(得分：0)
再次感谢
我放弃了恢复启动分区。 我从SDK中找到了uImage，完美修复：））
我尝试恢复rootfs时收到一条消息，指出文件系统没有正确的版本：（
所以我留下了SDK的rootfs并且运行良好：））
我有一些原始rootfs的二进制文件但是当我运行时我有这个：
btools: symbol '_h_errno': can't resolve symbol
btools: symbol '_h_errno': can't resolve symbol
btools: symbol '_errno': can't resolve symbol
btools: symbol '_errno': can't resolve symbol
我认为这是因为我没有原始内核的配置 你相信有解决方案吗？
