海思开发笔记：（一）海思Hi3519A开发环境搭建

参考海思官方文档：《Hi3519AV100╱Hi3556AV100 开发环境用户指南.pdf》、《Hi3519AV100 SDK 安装及升级使用说明.pdf》

1、安装ubuntu18.04虚拟机

虚拟机版本：VMware® Workstation 15 Pro
操作系统版本：ubuntu-18.04.1-desktop-x64
海思Hi3519A交叉编译工具只支持32位
ubuntu18.04无官方32位ISO镜像
ubuntu16.04的32位系统，正在vmware-tools无法正常复制文件的问题
所以选择ubuntu18.04 64位操作系统作为开发环境

# 系统版本
hisilicon@ubuntu:~$ uname -a
Linux ubuntu 5.3.0-28-generic #30~18.04.1-Ubuntu SMP Fri Jan 17 06:14:09 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
# 系统更新
hisilicon@ubuntu:~$ sudo apt update
......

hisilicon@ubuntu:~$ sudo apt upgrade
......

2、安装arm-himix200-linux工具链

切换到root账号或者使用sudo安装，避免权限不足
工具链默认会安装/opt/hisi-linux/x86-arm路径下
解压需要时间较长，需要耐心等待
由于开发环境操作系统为64位，工具链为32位，安装完成后直接运行相关命令会提示文件不存在
所以需要安装32位库：sudo apt install lib32z1-dev
如果修改软件源为阿里等国内镜像源，可能会因为源地址配置不全造成32位库安装失败

# 切换root
hisilicon@ubuntu:~$ sudo su
[sudo] password for hisilicon:

root@ubuntu:/home/hisilicon# cd Downloads/arm-himix200-linux/

3、安装Hi3519AV100SDK

SDK并不是真正的安装，而是当前目录解压展开，需提前规划好目录
由于默认shell的原因，直接运行./sdk.unpack会出错，可使用bash shell运行解包脚本

# 解压SDK
root@ubuntu:/home/hisilicon/3519A# tar -zxf Hi3519AV100_SDK_V2.0.2.0.tgz 
root@ubuntu:/home/hisilicon/3519A# cd Hi3519AV100_SDK_V2.0.2.0/
root@ubuntu:/home/hisilicon/3519A/Hi3519AV100_SDK_V2.0.2.0# ls
package  scripts  sdk.cleanup  sdk.unpack  smp_image_glibc
# 安装SDK
root@ubuntu:/home/hisilicon/3519A/Hi3519AV100_SDK_V2.0.2.0# /bin/bash sdk.unpack

/home/hisilicon/3519A/Hi3519AV100_SDK_V2.0.2.0

直接执行./sdk.unpack进行解压安装会报错，因为Ubuntu中，/bin/sh默认已经指向dash，这是一个不同于bash的shell，主要是为了执行脚本而出现，而不是交互，dash速度更快，但功能比bash少很多，语法严格遵守POSIX标准，出现错误后不会执行后续脚本命令。
解决方法1：
　　步骤1：/bin/bash sdk.unpack
解决方法2：
　　步骤1：vim scripts/common.sh; 第一行：#!/bin/sh->!/bin/bash
　　步骤2：vim sdk.unpack; 第一行：#!/bin/sh->!/bin/bash
　　步骤3：./sdk.unpack
解决方法3：
　　步骤1：sudo dpkg-reconfigure dash
　　步骤2：出现菜单问是否需要dash,选no.
　　步骤3：./sdk.unpack
