Create SD Card Image From Scratch

This page details how to create the JetBot SD card image from scratch.

This is useful in case you want to distribute a modified version of the JetBot SD card image.

1. Flash SD card by following Getting Started with Jetson Nano Developer Kit.

   • Use the username / password jetbot / jetbot
   • Make sure to log in automatically

2. Insert SD card into Jetson Nano and power on

3. Enable i2c permissions

   sudo usermod -aG i2c $USER

4. Install pip and some python dependencies

   sudo apt-get update
   sudo apt install python3-pip python3-pil
   sudo pip3 install --upgrade numpy 

5. Install the pre-built TensorFlow pip wheel by following these instructions

6. Install the pre-built PyTorch pip wheel we provide for this project.

   sudo pip3 install torch-1.0.0a0+18eef1d-cp36-cp36m-linux_aarch64.whl
   sudo pip3 install torchvision

7. Install traitlets (master, to support the unlink() method)

   sudo python3 -m pip install git+https://github.com/ipython/traitlets@master

8. Install jupyter lab

   sudo apt install nodejs npm
   sudo pip3 install jupyter jupyterlab
   sudo jupyter labextension install @jupyter-widgets/jupyterlab-manager
   sudo jupyter labextension install @jupyterlab/statusbar
   jupyter lab --generate-config
   jupyter notebook password

   You should then enter the password jetbot (unless you want to use a custom password).

9. Install this repo

   cd
   sudo apt install python3-smbus
   git clone https://github.com/NVIDIA-AI-IOT/jetbot
   cd jetbot
   sudo apt-get install cmake
   sudo python3 setup.py install

10. Install jetbot services

    cd jetbot/utils
    python3 create_stats_service.py
    sudo mv jetbot_stats.service /etc/systemd/system/jetbot_stats.service
    sudo systemctl enable jetbot_stats
    sudo systemctl start jetbot_stats
    python3 create_jupyter_service.py
    sudo mv jetbot_jupyter.service /etc/systemd/system/jetbot_jupyter.service
    sudo systemctl enable jetbot_jupyter
    sudo systemctl start jetbot_jupyter

11. Make swapfile

    sudo fallocate -l 4G /var/swapfile
    sudo chmod 600 /var/swapfile
    sudo mkswap /var/swapfile
    sudo swapon /var/swapfile
    sudo bash -c 'echo "/var/swapfile swap swap defaults 0 0" >> /etc/fstab'
    

12. Copy JetBot notebooks to home directory

    cp -r ~/jetbot/notebooks ~/Notebooks
