Set up your Raspberry Pi

Prerequisites

  1. Raspberry Pi 2 or 3 with internet access.
  2. A blank Micro SD card. We recommend an 8 GB (minimum 6GB) Class 6 or Class 10 microSDHC card for installing the Raspberry Pi OS and storing the CNN model.
  3. Arm DS-5 installed on a host PC running Windows or Linux. 
  4. Router and ethernet cable. This is to connect to the Raspberry Pi from a host PC using SSH. 

Set up Ubuntu MATE

Set up your Pi with Ubuntu MATE and prepare it for SSH access from a separate host machine. The general steps for this are:

  1. Download the Ubuntu MATE 16.04.02 image file.
  2. Uncompress it using unxz.
  3. Write the image to the MicroSD card, we use dd on Linux but there are many ways.
  4. Insert the MicroSD card in a Raspberry Pi 3 and start it up.

Once the new system starts up, go through the configuration steps and connect to the network using a wired or wireless connection from your host machine.

Next, enable SSH by entering this on the command line:

$ sudo raspi-config

Then select Interfacing Options:

And then select SSH:

With SSH enabled, use  the ifconfig command to see the IP address of the Pi:

$ ifconfig wlan0
wlan0     Link encap:Ethernet  HWaddr b8:27:eb:22:ab:26  
          inet addr:192.168.0.121  Bcast:192.168.0.255  Mask:255.255.255.0 

 

And then check that you can SSH to it from your host machine.

To save time, you can setup SSH with no password. For example:

$ ssh-copy-id 192.168.0.121
