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.正常默认编译bsp目录

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.烧录到开发板

将以上步骤编译完成的uboot、kernel、rootfs使用网口，烧写EMMC的方式烧录到开发板

2.3.板端未能顺利跑起来

烧录成功后，开发板重新上电，uboot正常跑起来，kernel也正常跑起来，但是挂不上文件系统

2.4.发现编译过程有问题

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.文件系统没东西

直接在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
