rk3399prod Debian10制作文件系统镜像问题

我按照WIKI制作文件系统时，我的板子flash的空间不够了，我挂载了一个SD卡来存储文件系统镜像。开始报tar: Exiting with failure status due to previous errors， 在网上查询了是有些文件没有权限之类的问题导致的，之后运行tar cvfpJ ./rootfs1.tar.xz {/bin,/boot,/debian,/dev,/etc,/home,/lib,/media,/opt,/proc,/root,/run,/sbin,/srv,/sys,/system,/tmp,/usr,/var} > /dev/null
打印tar的错误信息重新打包，但在打包过程中会出现以下日志，并且tar.xz的大小就不在增加了，不是上边的权限问题，以下这种错误信息怎么处理？

补一张图，上边粘贴的可能看不清

麻烦版主解答一下

tar命令 这边也没有退出，tar.xz包的大小却始终不变？  请解答一下

/sys   /dev 不要打包进去。 请按照教程操作。

打包命令请参考wiki文件系统制作章节操作，直接复制命令，不要随意修改！
sys和dev目录是系统生成的，不能打包

什么时候出1126的板子啊？
