• Download Jetpack : JetPack-L4T-3.1-linux-x64.run (need to login into NVIDIA Developer Portal)

Download and Install JetPack L4T

Host need to run Ubuntu 14.04 ( x64)

Make Swap

• Install Gparted using Ubuntu Software Center in Jetson TK1
• Insert your SD card
• Configure that SD card as linux-swap partition using Gparted
• Open fstab in Jetson TK1,

sudo gedit /etc/fstab

• Add below line at the end of config,

/dev/mmcblk1p1 none swap sw 0 0

[HINT] Configure swap on Jetson TK1

• Reboot and open Resource Monitoring app in Jetson TK1 to verify that swap work.

Automount HDD

• Attach HDD into Jetson TK1
• Run sudo fdisk /dev/sdb

1. Press O and press Enter (creates a new table)
2. Press N and press Enter (creates a new partition)
3. Press P and press Enter (makes a primary partition)
4. Then press 1 and press Enter (creates it as the 1st partition)
5. Finally, press W (this will write any changes to disk)

• Okay now you have a partition, now you need a filesystem.

1. Run sudo mkfs.ext4 /dev/sdb1
2. Now you can add it to /etc/fstab

#device        mountpoint             fstype    options  dump   fsck

/dev/sdb1    /home/yourname/mydata    ext4    defaults    0    1

This assumes the partition is formatted as ext4 as per mkfs above

• Then on the next reboot it will auto mount.
