实验室有块TX2，挺贵的一个开发板，长这个样子：
第一次拿到的小伙伴，右上角那个是电源，下面一排按钮，最右侧是power键，上电以后要按一下power键才能启动系统。
系统启动后，里面是有sshd的，可以远程连上操作，默认的ssh参数如下：
username: nvidia
password: nvidia
port:22
其实里面还是一个裸系统，需要安装NVIDIA相关的驱动等，资源文件已经放好了在
/home/nvidia/NVIDIA-INSTALLER
资源名字：
Tegra186_Linux_R28.1.0_aarch64.tbz2
现在最新版本应该都28.2了吧。
跟资源同级的目录里面有个install.sh
sudo ./installer.sh
一定sudo运行，sudo密码

不sudo会报错。
正常情况是这样：
nvidia@tegra-ubuntu:~/NVIDIA-INSTALLER$ sudo ./installer.sh
