TinyOS Installation Made Easy

Howdy people! Long time since a post but couldn’t help it, busy being a busybee.

Well, I have started a project on Wireless Sensor Networks and the best way to go about it has been using an amazing operating system called TinyOS. This OS is so tiny, it uses only 400 kb of memory to run! Holy Cow!!

But getting TinyOS on 64-bit machines hasn’t been well documented and I assume that lack of documentation brought you here. Well no fear, I will be showing a stepwise guide to getting TinyOS up-and-running on any 64-bit machine you have.

Note: I am using Ubuntu 11.10 64-bit as my host operating system, but the method should work on all distros of Linux.  If you’re using Windows, may God have mercy on your soul. Also, this post involves installing TinyOS 2.1.1. I cannot guarantee that all the steps will work as is for other older versions. You’ll have to do some research for that.

Step 1:

First up, we need Java, the JRE and the JDK as a lot of the TinyOS and Mote communication frameworks are built in Java. You can use the OpenJDK but I have found using Sun’s original JDK yields better results!

Open up a terminal and simply type in these commands to get the JRE and JDK installed in your machine.

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:ferramroberto/java
sudo apt-get update
sudo apt-get install sun-java6-jdk sun-java6-plugin

You can choose the appropriate JVM by running the following command in the terminal:

sudo update-alternatives --config java

Step 2:

Now that we have our environment setup, we are ready to install the TinyOS development environment.

  1. Install the Synaptic Package manager by running “sudo apt-get install Synaptic” in a terminal.
  2. In Synaptic, go to Settings ->Repositories.
  3. Click on 3rd party software and add the following (simple copy-paste):
    deb http://tinyos.stanford.edu/tinyos/dists/ubuntu * main
  4.  Click OK and reload your repositories.
  5. After reloading, simply search for TinyOS and select it. Click install and allow Synaptic to handle dependency installation for you.
  6. Once the packages have been properly installed, go back to a terminal and type “sudo gedit ~/.bashrc” and add this line at the absolute end:
                         source /opt/tinyos-2.1.1/tinyos.sh
  7.  Finally, close the current terminal and open up a new one and type in $MAKERULES. If all went well, you should get the path.

Congrats, we have TinyOS ready. But we’re not done yet!

Step 3:

Now, when writing TinyOS programs, you’ll very much want to simulate them to see what are the results. A very handy tool for TinyOS simulation is TOSSIM. But when you run the make micaz sim to generate your executable you might get a Python related error. Try these steps:

  1. In a terminal, run sudo apt-get install python-dev.
  2. Even after installing python, some configuration is required.
  3. Run python –version  and note the version of Python installed. In my case, it was 2.7.
  4. Go to /opt/tinyos-2.1.1/support/make/
  5. Open the sim.extra file in gedit with super user privileges.
  6. In the entry labelled PYTHON_VERSION, check to see if the entry matches with the Python version installed. For me, it was 2.6, so I changed it to 2.7.

Step 4:

As the final step, this involves some minor configuration to your tinyos.sh file found in /opt/tinyos-2.1.1. This is done so that when you run the make micaz sim command to generate TOSSIM related files, the appropriate Java classes are generated to help in the simulation. Otherwise you’ll get a long list of errors that will make no sense at all.

Editing the tinyos.sh file makes the change permanent which is exactly what you need. Simply go to the directory in which the tinyos.sh file is located (given in the start of  this step).

Open the tinyos.sh file in gedit with super user privileges. There is an entry called CLASSPATH. Simply edit the original to $TOSROOT/support/sdk/java/tinyos.jar, similar to how it is in the image.

CLASSPATH Edit

Change to CLASSPATH entry in tinyos.sh file

And voila!! You’re done and ready to start writing some incredible TinyOS code.

I hope this blog entry has been useful to you. For any doubts or problems, the TinyOS mailing list is a great place filled with really helpful people and I highly recommend posting both newbie and advanced doubts there.

Till next time, Eviva!
