Raspberry Pi Installation Guide

Please follow steps 1-8 for normal Linux Installation Guide.

During installation you will be asked to optimize your installation for performance on the Raspberry Pi.

Say YES! Make sure you have a stable Internet connection during the process, as you will be downloading a number of 3rd party open source libraries.

Raspberry Pi Wi-Fi

Note

Two Wi-Fi USB modules have been tested with KA Lite on the Raspberry Pi

  • Raspberry Pi WiPi adaptor
  • Edimax EW-7811Un

In our tests, we found that the WiPi adaptor supported a higher number tablet connections.

Installation

Note

The Raspberry Pi may crash if the USB adaptor is inserted or removed while the computer is switched on.

  • Make sure to shutdown and remove the power from the Raspberry Pi.
  • Afterwards, insert the wireless USB adaptor.
  • Lastly, switch the Raspberry Pi on.
  1. Make sure the Raspberry Pi operating system is up-to-date.
    • Login with the account used to install KA Lite

    • Update the Raspberry Pi operating system by:
      • sudo apt-get update
      • sudo apt-get upgrade
  2. Get the installation scripts.
    • cd /opt
    • sudo git clone https://github.com/learningequality/ka-lite-pi-scripts.git
  3. Install and configure the access point.
    • cd /opt/ka-lite-pi-scripts
    • sudo ./configure.sh

    Note

    If using the Edimax EW-7811UN, ignore the “hostapdSegmentation fault” error.

  4. Install the USB adaptor software.
    • If using the WiPi, run this command:
      • cd /opt/ka-lite-pi-scripts
      • sudo ./use_wipi.sh
    • If using the Edimax EW-7811Un, run this command:
      • cd /opt/ka-lite-pi-scripts
      • sudo ./use_edimax.sh
  5. Complete the access point configuration
    • sudo python ./configure_network_interfaces.py
    • sudo insserv hostapd
  6. Finally
    • sudo reboot
    • A wireless network named “kalite” should be available.
    • Connect to this network
    • If the KA Lite server is started, browse to 1.1.1.1
