文章讲述了在尝试编译Ubuntu20.04内核并烧录后，系统遇到持续重启的问题，主要表现为内核日志中的mount失败。问题在于缺少cpio命令，导致recovery.img文件异常。解决方法是安装cpio并重新编译内核。

编译了Ubuntu20.04的源码成功烧录后，出现问题：不断重启。内核日志输出如下：

查看编译信息，原因是cpio命令没有，但是./edge build -k编译内核命令还是编译过了，导致recovery.img生成不正常，大小为31M，正常情况下为61M

[EDGE DEBUG] Start boot image ...
[EDGE DEBUG] ./make_initrd.sh arm64
./make_initrd.sh: line 7: cpio: command not found
/root/rk3588-edge/rootfs/debian/initrd

解决方法安装cpio
