novacarrier-tx2-image-builder

Resources for setting up a Jetson TX2, to run on the Monash Nova Rover NVIDIA Jetson TX2 carrier board, the Novacarrier.

Requirements

• Linux-ish computer (Ubuntu 18.04+ recommended)
• bash shell
• ~30GB+ storage space
• ~3GB+ of internet download quota

Getting started

To build and compile the image sources

git clone https://github.com/leighleighleigh/novacarrier-tx2-image-builder
cd novacarrier-tx2-image-builder
sudo ./setup.sh # Follow the prompts 
sudo ./build.sh # Follow the prompts

To flash the image to the Jetson

cd local/Linux_for_Tegra/

# Enable the micro USB port
# On the novacarrier, you need to switch the jumper 
# from 'USB_A' to 'MICRO'. 
# MICRO = Jumper position is closest to edge of board
# USB_A = Jumper position is closest to center of board

# Put jetson into recovery mode
# 1. Turn on 12V power to the carrier
# 2. Hold down RCVRY button for 2 seconds
# 3. While holding RCVRY, Tap the POWER button to start the system
# 4. Release the RCVRY button after 2 seconds

# Check it exists
lsusb | grep "recovery"

# Begin flashing
sudo ./flash.sh jetson-tx2-devkit mmcblk0p1

Additional Jetson Scripts

├── jetson_scripts/
    ├── fan_pwm.sh 
        # Used to change the fan PWM manually
    ├── fix_uart0.sh
        # UART0 is normally used for the ttyS0 linux console, which prints kernel log information. 
        # To UART0 for other activities (such as GPS), you need to run this script to release it from the kernel command line parameters.
    ├── setup_can.sh
        # Enables the can0 and can1 interfaces
