Getting Started with Jetson Nano

Getting Started with Jetson Nano

 Jetson Nano - another SBC variant but specially cornered towards Artificial Intelligence. Yes, for processing huge array of data.

NVIDIA® Jetson Nano™ Developer Kit is a small, powerful computer that lets you run multiple neural networks in parallel for applications like image classification, object detection, segmentation, and speech processing. All in an easy-to-use platform that runs in as little as 5 watts.

Jetson Nano - Headless, pretty much similar one to raspberry pi 4.

In order for these steps to work, you should be using a recent version of JetPack.

Step 1.Requirements

  • Jetson Nano
  • 5V 4A Barrel Jack Power Supply
  • Micro USB cable
  • SD Card (64GB or 128GB)
  • Network card 

Step 2. Download the Nano SD card image

Step 3. Flash the image to the SD card

Flash the image to the SD card using balenaEtcher.


I recommend using at least a 64GB card,Once the image is flashed to the hard-drive

Step 4. Install your network card or dongle

Best recommeded is WiFi adapter plugged into one of the USB ports.

You also have the option of setting up with  network card.

Step 5. Insert the microSD card

Insert the microSD card into the Jetson Nano.

The microSD card goes in the back, just under the heatsink.

If you are looking down on the Nano the contacts must be face up.

The card reader has a spring so you have to gently push the card info the device.

On a B01 especially, make sure you don’t bend the nearby header pins.

Step 7. Connect the Micro-USB cable

Use a cable from a Raspberry Pi or an Android phone

Plug the Micro-USB cable into the Jetson Nano

Plug the other end into your computer or laptop

Step 8. Plug in the power jack

Plug one end of the 5V 4A power supply into the barrel jack on the Jetson Nano

Plug the other end into a wall socket or power strip

Step 9. Wait for the Jetson Nano to boot up

Wait for a drive to appear on your desktop

It may be labeled LT4-README.

Step 10. Connect over USB

If you have only one device you can connect to the Jetson Nano from the terminal using this command:


screen /dev/cu.usbmode* 115200 -L

If you had multiple devices, replace the wildcard with the full name.

Step 11. Fill in the config info

You should now see a screen like this:

System Configuration


 ┌────┤ License For Customer Use of NVIDIA Software ├─────┐

 │                                                        │

 │ Welcome to Jetson Initial Configuration                │

 │                                                        │

 │                         <Ok>                           │

 │                                                        │

 └────────────────────────────────────────────────────────┘

If Ok isn’t highlighted, press Tab

Press Enter

  • Accept the license agreement (Press Tab / Enter)
  • Select your language (in my case English / Tab / Enter)
  • Select your country (in my case United States / Tab / Enter)
  • Select your timezone (in my case Eastern / Tab / Enter)
  • Select UTC (the recommendation is to select Yes / Enter)
  • Select a new user name (in my case mitch / Enter)
  • Select a password (enter something unique then Enter)
  • Confirm the password (enter it again, then press Enter)
  • APP Partition Size (I use the recommended default)

Network configuration

If you aren’t concerned about networking right now, select dummy0: Unknown interface (note that DHCP will fail later, but you can skip that)

For Wireless ESSID for wlan0 enter your network name

In my case for Network configuration I selected WPA/WPA2 PSK

When prompted enter the pass phrase for your network

For hostname, backout the default string and enter your desired hostname (I chose jet2)

At this point you will be prompted to login with your username. But the connection may be in a weird state after you are done with the configuration. The easiest thing to do is to just kill the current Terminal window and open up a new one.

Note: When trying to setup networking on one attempt I ran into a failure. I tried again with the exact same credentials and it succeeded.

Step 12. Login over USB

Open up a new Terminal window

Connect over USB again:

screen /dev/ttyACM0 115200 

Login using your new username and password

Make sure you can see some files:

ls -ls

Step13. Remote Desktop

This looks more important of the previous things, kindly use xrdp software in ubuntu than the preinstalled vnc.

for some reasons, there is still a large error in the prespective of ubuntu blob img.
