Abstract
Today’s Automobiles require multiple advance features with a single touch, therefore there is a need for infotainment system
which handles both Information and Entertainment. This project reports an Infotain system for Automobile based on Beaglebone
Black development board by Embedding Android Operating System and Android applications on to the device. This infotain
system is capable to play multimedia files, provide information related to the Navigation, and create access to the Internet. The
main aim of the project is to build and customize the operating system according to the system requirement and developing
application softwares for the Infotainment sytem. This process of refining and building operating systems and applications for a
brand new boards is called Board Bring Up. Above reported Infotain system can be upgraded with different hardware modules
for better features in Navigation and Communication, since the board is equipped with more communication interfacing ports. An
voice guiding feature for driver using the map details, a Message popup feature which delivers the message to an control /
monitoring center would be added in future.
Key Words: Infotain, Beaglebone Black, Navigation, and Sitara.

1. INTRODUCTION
Infotainment system combines entertainment, multi-
media and driver information functions in single module.
They offer radio or satellite radio, CD/DVD player for
music and video, navigation system, data and multimedia
ports (USB, Blue tooth, line in, line out, video in) as well as
general and vehicle status information.
A Navigation system is a system that aids in navigation.
Navigation systems may be entirely on board a vehicle
vessel, or they may be located elsewhere and communicate
via radio or other signals with a vehicle or vessel.
Android is an operating system based on the Linux
kernel, and designed basically for touch screen mobile
devices such as smart phones and tablet computers.
Programmed using C for the core content and C++, Java for
interface of users.
1.1 Beaglebone black
The BeagleBone Black is the newest member of the
BeagleBoard family. The BeagleBoard is a low-cost, fan-
less single-board computer based on low-power Texas
Instruments processors. It is a lower-cost, high-expansion
focused development kit using a low cost Sitara ARM
Cortex-A8 processor from Texas Instruments. The
BeagleBone Black ships with Linux kernel 3.8, upgraded
from the original BeagleBone's Linux kernel 3.2. Operating
system for board are Android, Ubuntu, openSUSE and
Angstrom. The board also supports other OSes such as
FreeBSD, OpenBSD, QNX, MINIX 3, RISC OS, and
Windows Embedded.
2. EXISTING MODEL
The existing infotainment systems are capable to play
multimedia, providing access to navigation and vehicle
status. Present systems use specific company’s hardware
module and operating system of respective company. The
application for these systems would be prebuilt specifically.
2.1 Problem Definition
In the present day’s the flexibility of the operating sytem
and applications compatibility and availability of the
applications is very important. But the existing infotain
systems have very few applications supportable for the
company’s operating system. Other disadvantage of existing
system is the size of the device would be quite large and
some systems may have separate modules for entertainment
and information, hence there is wastage of space.
3. PROPOSED WORK
The project reports an proposed approach of building an
Infotain sytem based on android embedded system using
beaglebone black.The block diagram of the infotain system
is shown in Figure.1.The system contains a beaglebone
black development board, user interface devices ,a micro
SDcard in which the Android operating system and Android
application is embedded and plugged into the memory card
slot of the board ,an HDMI/DVI port compatible display
device, audio devices (speakers).

Building the infotain system would include developing
Android applications and building the Android operating
system compatible for the development board.
Hardware requirements for building system :
1. Beaglebone black board (target system )
2. Personal Computer (host system)
3. User interface devices
4. Display devices and speakers
5. Micro SD card (loaded with OS and application)
Software requirements for building system :
1. Eclipse tool
2. ADT(Android development Tool)
3. JRE (java runtime environment)
4. Android Source Code
5. Ubuntu 12.04 as a Host Operating System
6. Android Jelly Bean 4.1 as a Target Operating
System
The process of Building and customizing an operating
system ,developing application software for an specific
newly arrived board and making it work as per specification
is called Board Bring Up. In this project building the
operating system is achieved by executing commands in the
terminal window on the Linux operating system (host
system).The procedure would include building stage 1 boot
loader(MLO file ),stage 2 boot loader(u_boot),building
kernel file(UImage),building root file system(boot.scr)
,finally developing application and running on the core
operating system.
Flow chart for the media player application is shown
below in Figure.2.it shows the working of the mediaplayer
application on the android OS .Media files stored in the sd
card is loaded to the player initially , loading the buttons
,updating time and playing according to the user inputs.f the
media file is playing pause button is loaded and play button
loads if paused.the application checks any button
(repeat,shuffle) is activated and plays accordingly.
Fig.2. Flow chart of media player application
Flow chart for the Navigation application is shown in
Figure.3.Once the application is activated the grid view of
the map is loaded as predefined by the Google services, then
it loads the graphical map view and buttons (GPS on
/off),application displays the default location defined by the
programmer by the help of the image frames stored in the
database system. Application checks for GPS button on
condition if its true then the GPS device is tracked and
current location of the device is displayed on the device with
a dotted mark indicating the current location on the map.
Once the current location is pointed on map the application
would load surrounding location around the current location
.If the device changes its current position the GPS device is
again tracked and updates the current location. If the GPS

_______________________________________________________________________________________
module is not available or its switched off then application
only displays map has the which user points through
interfacing device.

4. RESULTS
The proposed system was tested on the beagle bone black
board by burning the operating system and application
software which was developed on to the memory card of the
board and the acceptable results were observed on the
display device. The screenshots of the results is shown in
figures below Figure.3 .In screenshot the image shows an
media player which loads the media files from SDcard of
board to player and plays according to the list created by the
user. The buttons would be able to play, pause ,stop,
forward ,rewind ,repeat, shuffle. The list button in the
mediaplayer would show the mediafiles list loaded for
playing..The screenshot shown in Figure.5.shows the
navigation application used for tracking and locating the
present location of the device(in case of this project it would
be an automobile).The circular button present at top of the
navigation screen is used for switching GPS device on/off.
Zooming in and zooming out is achieved by swiping and
tapping on the touch screen display device and dragging,
scrolling for normal devices.

5. CONCLUSION
The proposed system was built and executed on the
beaglebone black development board successfully with best
results. The scope of work can be extended with additional
applications to use voice guiding and popup message feature
based on map. Additional communication hardware modules
like GPS, GSM etc can be interfaced in future for advanced
communication features
