一、编译环境说明

SDK版本：Hi3519DV500R001C01SPC003
Linux版本：$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.5 LTS
Release: 18.04

二、报错现象

2.1.参考smp/a55_linux/source/bsp里面的readme_cn.txt进行对bsp目录的编译；默认编译参数是make BOOT_MEDIA=emmc LIB_TYPE=musl CHIP=hi3519dv500 all

2.2.编译完成后将uboot、kernel、rootfs烧录到开发板

2.3.烧录成功后，开发板重启后挂载不上文件系统

2.4.返回去查看SDK的编译的过程，发现在制作emmc根文件系统时有异常，如下图所示：

2.5.在windows下使用Linux Reader工具查看rootfs_hi3516dv500_96M.ext4文件系统，发现基本是空的

三、排查原因

3.1主要报错有以下3种类型：

Unknown/unhandled file type ‘目录’ file: ../../../../../smp/a55_linux/source/bsp/pub/rootfs_musl_arm64/lib64
debugfs: sif lib64 mode 0x41c0
lib64: File not found by ext2_lookup
debugfs: sif lib64 uid 1000
lib64: File not found by ext2_lookup
debugfs: sif lib64 gid 1000
lib64: File not found by ext2_lookup
debugfs: cd /lib64/
/lib64/: File not found by ext2_lookup
Unknown/unhandled file type ‘符号链接’ file: ../../../../../smp/a55_linux/source/bsp/pub/rootfs_musl_arm64/lib64/libstdc++.so.6
debugfs: sif libstdc++.so.6 mode 0xa1ff
libstdc++.so.6: File not found by ext2_lookup
debugfs: sif libstdc++.so.6 uid 1000
libstdc++.so.6: File not found by ext2_lookup
debugfs: sif libstdc++.so.6 gid 1000
libstdc++.so.6: File not found by ext2_lookup
Unknown/unhandled file type ‘普通文件’ file: ../../../../../smp/a55_linux/source/bsp/pub/rootfs_musl_arm64/lib64/libsecurec.so
debugfs: sif libsecurec.so mode 0x81c0
libsecurec.so: File not found by ext2_lookup
debugfs: sif libsecurec.so uid 1000
libsecurec.so: File not found by ext2_lookup
debugfs: sif libsecurec.so gid 1000
libsecurec.so: File not found by ext2_lookup

四、各种可能的方式尝试解决

4.1尝试过重新编译Python的版本，未能解决
4.2尝试过重新make clean&&make distclean&&make all，未能解决
4.3尝试过重新安装一个干净的ubuntu编译，未能解决
4.4实在不行还想着使用以前Hi3519AV100制作emmc文件系统的方式来制作

五、终于发现根本原因

5.1功夫不负有心人，终于找到根本原因：其实就是不能把Ubuntu的系统语言改成中文，需要将Ubuntu的系统语言修改回英文成功解决并能打包出ok的rootfs_hi3516dv500_96M.ext4文件系统
5.2成功制作emmc根文件系统如下图所示：

5.3开发板重新烧录根文件系统后顺利跑起来如下图所示：
