Installing JetBot Image on Jetson Nano: Data Preservation Concerns

Issue Overview

Users exploring the Jetson Nano ecosystem are interested in transitioning from the standard Jetson Nano image to the JetBot image. The primary concern is the potential loss of existing files and configurations during this transition. This issue highlights the need for clarity on image installation processes and data preservation methods when switching between different Jetson Nano software configurations.

Possible Causes

1. Misunderstanding of Image Installation Process: Users may not be aware that installing a new image typically overwrites the existing data on the storage device.

2. Lack of Clear Documentation: Insufficient or unclear documentation about the differences between Jetson Nano and JetBot images may lead to confusion.

3. Limited Knowledge of Jetson Ecosystem: Users might not be familiar with alternative methods of running JetBot software without completely replacing the existing image.

Troubleshooting Steps, Solutions & Fixes

1. Clarify Image Installation Process:

   • Understand that installing a new image on the SD card will overwrite existing data.
   • Before proceeding, back up all important files and configurations from the current Jetson Nano image.

2. Consider Alternative Approaches:

   • Instead of replacing the entire image, consider using the pre-built JetBot docker container on your existing Jetson Nano image.
   • This method allows you to run JetBot software without losing your current setup.

3. Using Docker Container:

   • If your Jetson Nano image doesn’t have Docker installed, install it first:

     sudo apt-get update
     sudo apt-get install docker.io
     

   • Pull the JetBot docker container:

     sudo docker pull nvcr.io/nvidia/jetbot:latest
     

   • Run the JetBot container:

     sudo docker run -it --runtime nvidia --network host nvcr.io/nvidia/jetbot:latest
     

4. Data Backup:

   • If you decide to install the JetBot image, perform a complete backup of your current system:
     • Connect an external storage device to your Jetson Nano.
     • Use the rsync command to backup your home directory:

       rsync -avz /home/your_username/ /path/to/external/storage/backup/
       

     • Save a list of installed packages:

       dpkg --get-selections > ~/package_list
       

5. Dual Boot Setup:

   • Consider setting up a dual boot system with both Jetson Nano and JetBot images.
   • This requires partitioning your SD card or using multiple SD cards.

6. Consult Official Documentation:

   • Review the official NVIDIA Jetson documentation for the most up-to-date information on image installation and JetBot setup:
     https://developer.nvidia.com/embedded/learn/get-started-jetson-nano-devkit

7. Community Support:

   • If issues persist, seek help from the NVIDIA Developer Forums or the JetBot GitHub repository:
     • https://forums.developer.nvidia.com/c/agx-autonomous-machines/jetson-embedded-systems/70
     • https://github.com/NVIDIA-AI-IOT/jetbot

By following these steps, users can make an informed decision about transitioning to the JetBot image while minimizing the risk of data loss and maintaining their existing Jetson Nano setup if desired.
