Installing TinyOS over different OS environments
 Windows XP, Vista, 7, 8, mobile …
 Mac OS X
 Linux Ubuntu, RedHat, Debian …
 Complicated environmental setup which is OS-dependent
Unified solution
 Installation over a virtual environment
 VirtualBox: Oracle Virtual Machine (VM) solution
• OS-independent run-time environment
• Works on any x86 architecture
 Enable automatic, hassle-free TinyOS installation
ECE 455/555 Embedded System Design 4

 Virtual Machine
 Run an OS instance residing in another OS
 TinyOS installation solution: run Linux Ubuntu over different types of host OS

Download and install VirtualBox: https://www.virtualbox.org/wiki/Downloads
Open VirtualBox. Click “ New ”
“ Name ”: up to you…
“ Type ”: linux
“ Version ”: Ubuntu
“ Memory size ” 1024Mb
Create a virtual hard drive. Please allocate at least 16GB space for the hard drive
Download Ubuntu from http://www.ubuntu.com/download/desktop
ECE 455/555 Embedded System Design 6

 Install Linux in VirtualBox with virtual hard disk referring to the downloaded Ubuntu.version.iso.
ECE 455/555 Embedded System Design 7





Repower Linux
Install Ubuntu on VirtualBox.
Open terminal in Ubuntu
Before installing TinyOS, you must include the TinyOS repository addresses into the repository source file.
 This can be done by editing the file:
/etc/apt/sources.list
as follows:
Run $ sudo gedit /etc/apt/sources.list
ECE 455/555 Embedded System Design 8




Include the following 4 lines at the end of the script:
#tinyOS deb http://tinyos.stanford.edu/tinyos/dists/ubuntu lucid main deb http://tinyos.stanford.edu/tinyos/dists/ubuntu maverick main deb http://tinyos.stanford.edu/tinyos/dists/ubuntu natty main
Save and close the “gedit” application.
Open the terminal console and execute the following command:
 $ sudo apt-get update
 $ sudo apt-get install tinyos
ECE 455/555 Embedded System Design 9

 Then you’re going to a list of the TinyOS version available as presented below:
ECE 455/555 Embedded System Design 10




Run the following command to install TinyOS 2.1.2.
 $ sudo apt-get install tinyos-2.1.2
 You’ll be asked to enter the administration password and to confirm one or two steps along the way.
Change the root…using : sudo passwd root
Type in your password. Then the terminal works in root.

Copy the file tinyos.sh
to /opt/tinyos-2.1.2 folder
 http://web.eecs.utk.edu/~weigao/ece455/fall2015/tinyos.
sh
Edit .bashrc: $ sudo gedit ~/.bashrc
 Add “source /opt/tinyos-2.1.2/tinyos.sh” to the end of
.bashrc file
Reboot terminal

Try to pair up with the person next to you
 One of you installs the BaseStation app
• /opt/tinyos-2.x/apps/BaseStation
 Another of you installs the Oscilloscope app
• /opt/tinyos-2.x/apps/Oscilloscope
 Your two motes should be linking as synchronized
Look into the /opt/tinyos-2.x/apps for more programs
