2、下载SDKManager，地址：https://developer.nvidia.com/zh-cn/embedded/jetpack
3、安装SDKManager
sudo apt install ./sdkmanager_1.3.1-7110_amd64.deb
sdkmanager
4、开始刷机
（1）登录SDKManager，选择nvidia developer模式，在弹出的浏览器界面中登录nvidia账号
（2）用附带的有绿色小图案的数据线连接tx2和虚拟机，tx2需开机
（3）按下图选择版本
（4）全选，可修改安装路径，勾选accept…及download now install later，先将所有模块都下载下来，避免安装的时候报错，需要重新下载
（5）等待下载完成后，点击back to step one，直到step 2，不勾选download now install later，因为（4）已经下载完了，然后进入step 3，开始安装
（6）弹出以下弹窗时，选择Manual Setup，然后操作tx2：
a.拔掉电源适配器后重新插上
b.按一下power键开机(稍微有一定的按键时长后松开)
c.长按REC(RECOVERY FORCE)不要松开
d.再按下RST键(reset按下松开,稍微有一定的按键时长)
e.REC键再保持两秒后松开
f.再点击界面上的flash按钮
（7）弹出以下弹窗时，将tx2连接到另一台空闲的PC机上，其后操作同安装Ubuntu，设置用户名和密码，并更换Ubuntu镜像源：
sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak
sudo vim /etc/apt/sources.list
