                Install Grinch Linux4Tegra (L4T) version 19.3.6 for NVIDIA Jetson TK1
              
          
    For this process you will need:

A host desktop or laptop computer running Ubuntu Linux 12.04. This may be a VM, I've used VirtualBox.
Micro USB cable provided with the Jetson TK1 kit
Jetson TK1 and power supply
Optional: DB9 null modem cable if you want to use the serial console during boot


On your host computer open a Terminal, then create a directory to operate from, and switch to it. As an example:

mkdir ~/Grinch
cd ~/Grinch
