Online Upgrading and Downgrading Jetpack Versions on Jetson Devices

Issue Overview

Users are inquiring about the possibility of upgrading or downgrading Jetpack versions on Nvidia Jetson devices without completely reflashing the system. Specifically, they want to know if it’s possible to:

1. Upgrade from Jetpack 5.1.3 to version 6.x online
2. Downgrade from Jetpack 5.1.3 to version 5.1.2 online

The main concern is finding alternatives to the full system reflash process for version management.

Possible Causes

1. Limited update mechanisms: Nvidia may have restricted update options to ensure system stability and compatibility.
2. Complexity of system components: Jetpack includes various interdependent components, making partial updates challenging.
3. Hardware-specific requirements: Different Jetson models may have unique update processes or limitations.
4. Security considerations: Online upgrades and downgrades might pose security risks if not properly implemented.

Troubleshooting Steps, Solutions & Fixes

1. Online Upgrade Process:

   • Nvidia provides an Image-Based Over-the-Air (OTA) update mechanism for upgrading Jetpack versions.
   • Refer to the Nvidia Developer Guide section "Updating Jetson Linux with Image-Based Over-the-Air Update 6" for detailed instructions.
   • This method allows for online upgrades without completely reflashing the system.

2. Downgrade Limitations:

   • Online downgrading is not supported by Nvidia.
   • To apply a previous release version, you must re-flash the target device.

3. Upgrade Steps (general outline):

   • Ensure your device is connected to the internet.
   • Back up any important data before proceeding.
   • Follow the OTA update instructions in the Developer Guide.
   • Monitor the update process and do not interrupt it.
   • Reboot the device after the update is complete.

4. Downgrade Process:

   • Download the desired previous Jetpack version from the Nvidia Developer website.
   • Prepare a host computer with the Nvidia SDK Manager installed.
   • Connect your Jetson device to the host computer.
   • Use the SDK Manager to flash the previous Jetpack version onto your device.
   • This process will erase all data on the device, so ensure you have backups.

5. Best Practices:

   • Always check the release notes for the target Jetpack version before upgrading.
   • Ensure your device has sufficient storage space for the update.
   • Keep your current version up-to-date with the latest security patches before attempting major version upgrades.
   • If possible, test the upgrade process on a non-production device first.
