¶ Install development SDK
Until you understand your behaviour, please do not update the
ubuntu system in Jetson Nano. Updating in jetson nano via APT may render the system unusable.
¶ Install SDK Manager 2.2
Tips: If you are using virtual machine software such as `VMWare``, remember to connect the device into the virtual machine.
Check if there is a connection to the device with the following command.
$ lsusb
Bus 001 Device 029: ID 0955:7020 NVidia Corp.
Install SDK Manager 2.2
$ sudo apt install ./sdkmanager_2.1.0-11600_amd64.deb
Check FAQ for errors in installing SDK Manager 2.2 error on ubuntu 18.04, ubuntu 20.04
¶ Reset eMMC img
If you re-burn eMMC using
SDK Manager 2.2, Do not connect devices to the 4 USB 3.0 ports while burning!
SDK Manager 2.2 uses two folders to manage dependency packages and firmware
Download folder: Storing dependency packages file
Targer HW image folder:Storing compiled files and image files
¶ Installation with SDK Manager
tegra210-p3448-0002-p3449-0000-b00.dtb
To install Jetson OS via SDK Manager, you also need to replace the dtb file. Please refer to the terminal installation method, backup and replace the dtb file in the nvidia folder of the host pc.
Some issue - Click to expand/collapse
If you are experiencing
- Stagnate at 99.80%
- Being prompted by SDK Manager to install for a long time is not a normal state.
Try removing all the devices on the Nano USB3.0, then try using SDK Manager again.
¶ Installation using a terminal
workspace - Click to expand/collapse Workspace
- Extract the Driver Package (BSP)
- Extract the Sample Root Filesystem (rootfs)
$ mkdir workspace
$ cd workspace
$ cp Your/Nvidia/SDK/PATH/Jetson-210_Linux_R32.7.6_aarch64.tbz2 ./
$ cp Your/Nvidia/SDK/PATH/Tegra_Linux_Sample-Root-Filesystem_R32.7.6_aarch64.tbz2 ./
$ tar xvf ./Jetson-210_Linux_R32.7.6_aarch64.tbz2
$ cd ./Linux_for_Tegra/rootfs/
$ sudo tar xpvf ../../Tegra_Linux_Sample-Root-Filesystem_R32.7.6_aarch64.tbz2
If NVIDIA updates the SDK version, no extra notification will be given, so please adjust accordingly.
- Replace the driver file to support SD cards.
The system provided by NVIDIA does not support SUB Kit SD card recognition, so you need to replace
$ sudo Your/PATH/workspace/Linux_for_Tegra/apply_binaries.sh
When it shows success, proceed to the next step.
$ sudo cp Your/PATH/workspace/Linux_for_Tegra/kernel/dtb/tegra210-p3448-0002-p3449-0000-b00.dtb Your/PATH/workspace/BAK_tegra210-p3448-0002-p3449-0000-b00.dtb
$ sudo cp Your/PATH/workspace/tegra210-p3448-0002-p3449-0000-b00.dtb Your/PATH/workspace/Linux_for_Tegra/kernel/dtb/
- Put the jetson nano in Recovery mode (short GND, FC_REC pins), run the burn command
$ sudo Your/PATH/workspace/Linux_for_Tegra/flash.sh jetson-nano-emmc mmcblk0p1 # After modification, generate a new image.
For burning backup images,no re-generation of the image, just image burning.
$ sudo Your/PATH/workspace/Linux_for_Tegra/flash.sh -r jetson-nano-emmc mmcblk0p1 # No re-generation of the image, just image burning.

¶ Install Jetson SDK Components (CUDA, etc)
Please check if you have enough storage space, onboard 16GB eMMC is not enough space to install all Jetson SDK Components!
¶ Installation with SDKmanger
CUDA installation without shorting FC_REC and GND.
If it is disconnected, check that the host computer is connected to the nano via the mirco-USB cable.

¶ Installation using a terminal
It needs to be operated on the Jetson Nano, not on the host computer. Requires Nano to have Internet access.
sudo apt update
sudo apt install nvidia-jetpack
¶ Install Jtop on Jetson nano
Jtop is a system monitoring utility for Jetson that can be run on a terminal to view and control the status of NVIDIA Jetson in real time.
sudo apt‐get install python3‐pip
sudo ‐H pip3 install ‐U jetson‐stats
use command jtop to check nano status.
