Jetson Nano的U盘启动烧录镜像eMMC遇到的一些问题_detected selected device is not in recovery mode.

nvidia SDK Manager: No SDKs are avaliable for your account的解决办法

原因：下载的SDK Manager版本太老，新版中合并了一些SDK，在旧版中就无法获取了。我是从Jetpack 4.5.1的页面下载的，所以版本是1.6.1，但官网最新版已经到了1.9

解决方法：打开SDK Manager | NVIDIA Developer，下载最新版，重新覆盖安装

Detected selected device is already in recovery mode. Please 1. double check if correct target device has been selected. 2. if does, change to 'Manual Setup' to continue.

解决方法：将1.中 Automatic改为Manual 

There is not enough space. Need additional 24801 MB on /dev/sda1 Do you want to continue installation anyway?

解决方法：给虚拟机扩展磁盘容量
