Cloning the System

Repeating the procedures in the previous articles may take a lot of time. It's advised to clone the system after you have set up common stuff for each device, save the image on one device and restore the image to all other devices.

Prerequisites

Hardware

  • Power cable of the Jetson module, plugged in.
  • USB to Micro-B cable, connected from your computer to the device.

Software

  • Ubuntu 14.04 or higher, on your computer.
  • JetPack, having installed at least once and the directory 64_TX2/Linux_for_Tegra_tx2 exists.

Save the System

TIP: See Recommended Setups Before Saving to have a clean workspace.

  1. Go to the TX2 directory by running:
    cd 64_TX2/Linux_for_Tegra_tx2
  2. Repeat the steps #3.12-3.13 in Install with JetPack to put it in force USB recovery mode. No need to press "Enter" though.
  3. Replace the contents in flash.sh with the on in the post.
  4. Start saving by running:
    sudo ./flash.sh -r -k APP -G system.img jetson-tx2 mmcblk0p1
  5. Reboot the device to make it go back to the normal state.
  6. Move system.img to other place or just leave it there.

INFO: Saving takes much longer time than restoring.

INFO: system.img.raw is also created, you can safely delete it.

TIP: You can use Gzip to compress the .img file to save space.

Restore the System

  1. Repeat steps #1-2 in Save the System.
  2. Copy the image you want to restore to 64_TX2/Linux_for_Tegra_tx2/bootloader directory and name it system.img.
  3. Start restoring by running:
    sudo ./flash.sh -r jetson-tx2 mmcblk0p1
  4. Reboot the device for the changes to take effect.
  • Unpin unused applications on the task bar.
  • Pin "Chromium Web Browser" and "Terminal" on the task bar.
  • Disable Wi-Fi.
  • Disable screen lock.
  • Disable keyring.
  • Clean APT cruft:
    sudo apt-get clean
sudo apt-get autoclean
sudo apt-get autoremove
  • Clean history:
    history -c
rm ~/.bash_history
