__TOC__

== Introduction ==

[http://beagleboard.org/BLACK BeagleBone Black] is a low-cost, community-supported development platform for developers and hobbyists. Boot Linux in under 10 seconds and get started on development in less than 5 minutes with just a single USB cable.

This page describes the installation of Paparazzi and dependencies to get the [[GCS]] running on the BBB.

== Ubuntu ==

The simplest is to install Ubuntu on the BBB. See http://elinux.org/BeagleBoardUbuntu

The Ubuntu 14.04.1 console image works nicely, but comes without a graphical desktop, so you might want to install LXDE:

$ sudo apt-get install lxde

Now add the Paparazzi-uav PPA and install the software:

The ''software-properties-common'' package is needed for the ''add-apt-repository'' command:

$ sudo apt-get install software-properties-common

$ sudo add-apt-repository ppa:paparazzi-uav/ppa
$ sudo apt-get update
$ sudo apt-get install paparazzi-dev gcc-arm-none-eabi

Done, you have installed all Paparazzi dependencies.

== Building Paparazzi ==
* Get the paparazzi source as per usual, using your desired method/setup as described in [[git]], e.g.:
$ <nowiki>git clone https://github.com/paparazzi/paparazzi.git</nowiki>
* Now change to the paparazzi directory
$ cd paparazzi
* Set the PAPARAZZI_HOME and PAPARAZZI_SRC environment vars
$ git checkout master
* Build Paparazzi:
$ make
* Build the native versions of the GCS and Server (which will run faster)
$ make ground_segment.opt

== Trying it out ==

=== Running directly on the BBB ===
SSH into your BBB with X11 forwarding (using the <tt>-X</tt>) option.
* <tt>$ cd ~/paparazzi</tt>
* <tt>$ ./paparazzi</tt>
* You should see a window pop up on your local machine with paparazzi center.
* You can then launch a session as usual...
* To get some more speed, use the native version of the GCS and server by running ''sw/ground_segment/cockpit/gcs.opt'' and ''sw/ground_segment/tmtc/server.opt'' instead of the non-opt versions.

=== Remote GCS/Messages ===
Next, one can try simulating on the local machine, and pushing the ivy bus messages across the local network and reading them with the programs on the BBB.

* Build and test an airframe you wish to simulate as usual on the local machine, and test it quickly by simulating
* Stop all the agents, and add the following option to the call: <tt>-b <local network broadcast ip></tt> (for example <tt>192.168.0.255</tt>)
* Before running programs on the BBB, it needs to know about the freshly compiled airframe. So, copy the <tt>conf/conf.xml</tt> file from the local machine to the BBB, and also the whole <tt>var/</tt> folder intact, AFTER having compiled for simulation
* Restart the agents on the local machine with the ivy bus option, everything should be working as before
* Now start messages on the BBB as described above, but set the bus to the same IP as the local machine (you can also try out the GCS by running <tt>$ sw/ground_segment/cockpit/gcs -b <local network broadcast ip></tt>)
