电视盒子刷机教程
https://www.histb.com/ 海思刷机教程以及刷机安装包。
刷机有三种方式：
- U盘刷机，就是利用U盘，然后短接后系统进入升级模式后刷机
- USB刷机，利用双公头USB线，然后使用adb软件刷机，下载adb并配置环境变量
- TTL线刷，有的机器不支持TTL，比如Hi3789mv100，TTL线可以连接，但是串口不打印数据
ubuntu wifi驱动：
刷机ubuntu后发现wifi网卡没有启动，执行lsusb，看到无线网卡型号：
root@hi3798mv100:~# lsusb
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
查找RTL8188ETV的KO并加载

2、驱动包
目前有Hi3798mv100大部分机型都适用的RTL8188FTV、RTL818ETV的驱动，mv200和mv300并不使用，另外后缀对应相应的nas系统日期版本，版本之间无法通用。
rtl8188etv-0302.tar.gz
rtl8188ftv-0302.tar.gz
rtl8188etv-0403.tar.gz
rtl8188ftv-0403.tar.gz驱动包下载：
链接：https://pan.baidu.com/s/10QmX6Z4mb_p_9SdOC4BMUQ
提取码：q1xj下载rtl8188etv-0808.tar.gz、hi_kernel-mv100-0808.bin、wifi_install.sh。其中rtl8188etv-0808.tar.gz为网卡驱动KO包、hi_kernel-mv100-0808.bin需要更新内核版本包、wifi_install.sh安装文件。
执行安装命令
#更新内核，如果内核版本为4.4.35_ecoo_81092768，则不需要更新
dd if=./hi_kernel-mv100-0808.bin of=/dev/mmcblk0p6 bs=1M count=1024
#加载网卡驱动KO
sh wifi_install.sh -f rtl8188etv-0808.tar.gz -s 123 -p 123
查看网卡驱动
#vermagic为内核版本号，需要安装内核版本一致，否则不能安装
