Post Installation¶

Adding a SSD Disk¶

In order to add a SSD disk in Jetson board, we have to connect a SATA cable and a power cable in the board as illustrated in the image below:

After connecting the SSD disk, we format it using ext4 file system by logging into Ubuntu and accessing Disks application. Inside the application, select the SSD disk and click on the gear and select Format (or press Shift+Ctrl+F). Then, add a name to the disk (e.g. JetsonSSD) and click in Format, as the images below:

After formating the SSD disk, we have to mount it at startup. In order to do it, we have to add a call in /etc/fstab with the mounting point. In order to add this line, we have to discover the uuid of the device. With the disk manually mounted, we run the mount command to discover where the SSD is mounted, obtaining:

$ mount
/dev/sda on /media/ubuntu/JetsonSSD type ext4 (rw,nosuid,nodev,uhelper=udisk2)

Knowing the mounting local of the SSD disk (/dev/sda), we have to discover its uuid. To discover the uuid we run:

$ ls -al /dev/disk/by-uuid
lrwxrwxrwx 1 root root   9 Dec 31 21:00 ac183b24-3e75-4190-bcb7-32160e9a7c55 -> ../../sda

Having the uuid of the disk we can add a line to the /etc/fstab with a call to the mounting point. Running the command:

$ sudo gedit /etc/fstab

We add the following line to the file:

/dev/disk/by-uuid/ac183b24-3e75-4190-bcb7-32160e9a7c55 /media/JetsonSSD ext4 defaults 0 2

Save the file and close it. Next time Ubuntu is started, the SSD disk will be mounted at startup.

Important Packages¶

Here we add several packages that should be installed to work in Jetson. All packages are installed via apt-get. In order to easily install all packages a script was created and can be downloaded by running:

$ wget --no-check-certificate --content-disposition https://raw.githubusercontent.com/lsa-pucrs/platypus_doc/master/docs/source/jetson/scripts/additionalPackages.sh
$ chmod +x additionalPackages.sh
$ ./additionalPackages.sh

The script installs the following packages:
