Firmware upgrade
First of all, make sure you have entered recovery mode! ! !
- Open the Ubuntu18.04 virtual machine (or computer host), run the SDK Manager to open the software.
- Set up the device to connect to the virtual machine
- Log in to the account, if the Jetson Nano is recognized normally, the SDK Manager will detect and prompt for options.
- In the JetPack option, take the JetPack4.6 system as an example, uncheck Host Machine, and click CONTINUE.
- Select Jetson OS, and remove the option of Jetson SDK Components. Check the protocol and click CONTINUE.
- It may prompt that the memory is insufficient, don’t worry about it, just click Continue.
- The path saved by Imager is fine by default. If you select Create, the path will be created automatically.
- Enter your virtual machine password
- The installation time is long, the following information will be prompted, just click Yes
- Starting from JetPack4.6.1, the preconfig window will pop up when using the SDK Manager firmware upgrade. Here, select Manual Setup - Jetson nano as shown in the figure below, and select Pre-config to set the username and password of the jetson nano upgraded system in advance. You can also choose Runtime to set the user name and password later.
- Wait for the download to complete the upgrade.

¶ SDK installation
Jetpack mainly includes system images, libraries, APIs, developer tools, examples and some documentation. In the SDK Manager software, we first install the OS, which is the system image, and the uninstalled part is the SDK, as shown in the figure below, you can use the command to install directly or use the SDK Manger to install:
The SDK includes TensorRT, cuDNN, CUDA, Multimedia API, Computer Vision, and Developer Tools.
The above are some functions of the SDK. When the previous system is installed, only the basic system is installed. Other JetPack SDK components, such as CUDA, need to be further installed after the system starts normally. Here are the steps to install the SDK. If you want to install this part, please ensure that the TF card or U disk is the main system, because the downloaded content may cause the EMMC disk capacity to run out.
¶ Install using SDK Manager
When using the SDK Manager to install the SDK, there is no need to set the nano to recovery mode, that is, there is no need to short-circuit the pins.
¶ Install using the command
Users who do not have ubuntu or a virtual machine can choose to install directly on Jetson Nano using the following instructions
sudo apt update
sudo apt install nvidia-jetpack
