创建步骤
1、busyBox的编译
busyBox的作用是提供linux下的一系列命令工具，独立于内核，因为内核提供管理但不提供工具。目标平台不同，就需要使用不同的交叉编译工具链进行编译，编译步骤很简单。来源见参考1。

SDK中提供busyBox的源码故无需下载。在 /Hi3516CV500_SDK_V2.0.1.0/package/osdrv/opensource/busyBox 目录下解压busyBox-1.26.2.tgz。修改Makefile中的 ARCH 和 CROSS_COMPILE 两项。
#CROSS_COMPILE ?=
CROSS_COMPILE ?= arm-himix200-linux-
# bBox: we may have CONfig_CROSS_COMPILER_PREFIX in .config,
# and it has not been included yet... thus using an awkward Syntax.
ifeq ($(CROSS_COMPILE),)
CROSS_COMPILE := $(shell grep ^CONfig_CROSS_COMPILER_PREFIX .config 2>/dev/null)
CROSS_COMPILE := $(subst CONfig_CROSS_COMPILER_PREFIX=,,$(CROSS_COMPILE))
CROSS_COMPILE := $(subst ",,$(CROSS_COMPILE))
#")
endif

# SUbarCH tells the usermode build what the underlying arch is. That is set
# first, and if a usermode build is happening, the "ARCH=um" on the command
# line overrIDes the setting of ARCH below. If a native build is happening,
# then ARCH is assigned, getting whatever value it gets normally, and
# SUbarCH is subsequently ignored.

ifneq ($(CROSS_COMPILE),)
SUbarCH := $(shell echo $(CROSS_COMPILE) | cut -d- -f1)
else
SUbarCH := $(shell uname -m)
endif
SUbarCH := $(shell echo $(SUbarCH) | sed -e s/i.86/i386/ -e s/sun4u/sparc64/
                   -e s/arm.*/arm/ -e s/sa110/arm/
                   -e s/s390x/s390/ -e s/parisc64/parisc/
                   -e s/ppc.*/powerpc/ -e s/mips.*/mips/ )

#ARCH ?= $(SUbarCH)
ARCH ?= arm

在命令行输入
make menuconfig

进入配置菜单。选中BusyBox Settings->Build Options->Build BusyBox as a static binary (no shared libs)项（空格键选中）。如下图所示：

其它的配置项均遵从默认即可。退出配置菜单并保存。

BusyBox Settings --->
--- Build Options
[*] Build BusyBox as a static binary (no shared libs)

命令行下输入：
make
make install
即可在busyBox目录下生成 _install 文件夹。这里面存放的就是linux下 *** 作的基本命令了。

--------------------------------------------------
You will probably need to make your busyBox binary
setuID root to ensure all configured applets will
work properly.

（make all已经全部编译过了！）
2、海思工具的编译
在 Hi3516CV500_SDK_V2.0.1.0/package/osdrv/tools/board 目录下，存放了板端可能用得到的工具。在 Hi3516CV500_SDK_V2.0.1.0/package/osdrv/tools/pc 目录下，则需要使用 make_ext4fs 工具。

2.1 himm工具的编译
himm工具是海思提供的可以直接 *** 作SOC寄存器的工具，当配置IO复用或者调整IRCUT等的时候，可能会用上。himm工具在板端目录下的 reg-tools-1.0.0 文件夹内，命令行进入直接输入 make 编译即可。

2.2 make_ext4fs工具的编译
ext4是用于emmC的文件系统，make_ext4fs工具在pc端目录下的 ext4_utils 文件夹内，如果安装过程中出错，提示 cannot find uuID library required for mkfs.ubifs ，则验证有没有安装以下依赖包：
sudo apt install libuuID1:i386 zlib1g-dev liblzo2-dev uuID-dev pkg-config
而后重新 make 即可。本步骤来源见参考2。

3、建立根文件系统的目录
Z:Hi3516CV500R001C02SPC021ReleaseDoczh 1.softwareboardOSDRVHi35xxVxxx 开发环境用户指南.pdf（P17-P26）
本阶段步骤部分来源为：《Hi3516CV500╱Hi3516DV300╱Hi3516AV300 开发环境用户指南》

找一个自己喜欢的目录，建一个用于存放根文件系统的文件夹，比如这里就单纯的命名为 rootfs 。

3.1 复制busyBox编译的文件到rootfs目录
这一步很简单，因为目录还是空的，所以直接拷贝busyBox目录下的 _install 中全部文件（夹）到 rootfs 目录即可。

3.2 复制himm工具到rootfs
在himm工具编译完后，将其目录下 bin 文件夹中的内容复制到 rootfs/bin 中，这样就算完成了。

3.3 填充etc目录
进入目录：
/Hi3516CV500_SDK_V2.0.1.0/package/osdrv/opensource/busyBox/busyBox-1.26.2/examples/bootfloppy/etc
将其中的所有文件拷贝到 rootfs/etc 中，这将作为kerne的“启动”文件夹。

3.4 填充lib目录
Hi3516DV300芯片具有浮点运算单元和neon，程序运行需要依赖编译工具提供的运行库，进入海思arm-himix200-linux-工具链对应目录下：
cd /opt/hisi-linux/x86-arm/arm-himix200-linux/runtime_glibc/a7_softfp_neon-vfpv4
可以看到其中有一个孤零零的 lib.tgz 文件，解压到rootfs中的lib文件夹内即可。

这里，200M指的是根文件系统所占emmC的大小，可以根据需要修改，-s后面是生成的镜像名，rootfs为待压缩的目录。
至此，得到根文件系统镜像，使用Hi_Tool或者手动 *** 作uboot进行烧录均可。

5、刷机（先擦除全器件，然后再烧写！）
setenv bootargs 'mem=128M console=ttyAMA0,115200 clk_ignore_unused rw rootwait root=/dev/mmcblk0p3 rootfstype=ext4 blkdevparts=mmcblk0:1M(uboot.bin),9M(kernel),200M(rootfs.ext4),-(user)'
setenv bootcmd 'mmc read 0 0x80000000 800 4800; bootm 0x80000000'
saveenv
reset

刷机之后启动的LOG：
