Flashing new firmware on the Jetson Orin Nano can be done through various methods. While you’ve mentioned the Ubuntu approach, I’ll outline a few options and provide a comparison.
1. Ubuntu Approach:
The Ubuntu approach involves using the apt package manager to update the firmware. This method is straightforward and can be done using the following steps:
- Connect to the internet
- Update the package list:
sudo apt update - Upgrade the firmware:
sudo apt full-upgrade
This method is easy to use, but it might not always provide the latest firmware updates.
2. Image-based OTA:
Image-based OTA allows you to create OTA payload packages and update the full image running on the Jetson Orin Nano, partition by partition. This method provides more control over the update process and can be used to update specific partitions.
To use image-based OTA, you’ll need to:
- Create an OTA payload package using the
otatool - Flash the payload package to the device using the
flash.shscript
This method requires more technical expertise, but it provides more flexibility and control over the update process.
3. Debian package management-based OTA:
Debian package management-based OTA can update Jetson devices that run Jetson Linux or Jetson components on a host computer. This method uses the apt package manager to update specific packages.
To use Debian package management-based OTA, you’ll need to:
- Update the package list:
sudo apt update - Upgrade specific packages:
sudo apt install <package_name>
This method is similar to the Ubuntu approach, but it provides more control over which packages are updated.
Comparison:
| Method | Ease of use | Control over update process | Flexibility |
|---|---|---|---|
| Ubuntu Approach | Easy | Low | Low |
| Image-based OTA | Medium | High | High |
| Debian package management-based OTA | Medium | Medium | Medium |
In conclusion, the choice of method depends on your specific needs and technical expertise. If you’re looking for a simple and straightforward approach, the Ubuntu approach might be the best option. However, if you need more control over the update process or want to update specific partitions, image-based OTA or Debian package management-based OTA might be a better choice.
As for flashing new firmware on the Jetson Orin Nano, you can use the flash.sh script provided by NVIDIA. This script can be used to flash the device with a new firmware image.
To flash new firmware on the Jetson Orin Nano, follow these steps:
- Download the latest firmware image from the NVIDIA website
- Extract the firmware image to a directory on your host computer
- Run the
flash.shscript, specifying the firmware image and the device to be flashed
For example:
./flash.sh -i <firmware_image> -d <device_name>
Replace <firmware_image> with the path to the firmware image, and <device_name> with the name of the device to be flashed.
Note: Before flashing new firmware, make sure to back up any important data on the device, as the flashing process will erase all data on the device.

Hi,
Yes, using Ubuntu to flash the device firmware is our standard method.
Thank you for your understanding.
Thanks.
Hi
Please install SDK Manager on your native Ubuntu system (not in a virtual machine), and use SDK Manager to perform a full flash of your device.
Thank you.
