Note: While you can still use this method to add a swap file, note that newer versions of L4T/JetPack have swap memory as part of the default distribution, implemented through zram. You may choose to use both a swapfile, as implemented here, and the zram swap memory at the same time.

Install a swap file on the NVIDIA Jetson Nano Developer Kit. This should help with memory pressure issues.
installSwapFile.sh - Create a swap file ; Use on external media like USB drive or SSD
usage: installSwapFile.sh [[[-d directory ] [-s size] -a] | [-h]]
-d | --dir [directoryname] Directory to place swapfile (defaults to /mnt)
-s | --size [gigabytes] (defaults to 6 )
-a | --auto Enable swap on boot in /etc/fstab (default: "Y")
-h | --help This message
Defaults to creating a 6GB Swapfile in the current directory
Note: If you enable swap on boot, you should also automount the drive that you're using
Automount a device given the label
autoMount.sh - Automount a device, useful for external media like USB drives
usage: autoMount.sh [ [-l label] | [-h]]
-l | --label [labelname] Label to lookup
-h | --help This message
Example usage:
$ ./autoMount.sh -l RaceUSB
where RaceUSB is the label of the device mounted at /media/jetsonhacks/RaceUSB
Tool to help automount the device given from the label The script looks up the device, mounting point and UUID for the given label Optionally add it to /etc/fstab
This is useful in case you run out of space. A simple manual procedure:
sudo swapoff -v /mnt/swapfile
sudo vim /etc/fstab and remove the line containing /mnt/swapfile
sudo rm /mnt/swapfile
sudo reboot
