Introduction
This document describes how start GOAL with the Raspberry Pi 3.
Required Hardware and Software
Following hardware and software is required for running GOAL on Raspberry Pi.
a Raspberry Pi 3 B+
a power supply for Raspberry Pi,
PC with Linux OS
GCC and the arm-gcc-linux-eabihf cross compiler (available at APT)
GOAL Software package/ release
Preparing the Raspberry Pi
Connect the Raspberry Pi to your local network via Ethernet. To access the device, either connect a monitor, keyboard and mouse via the provide HDMI and USB connectors or connect to the device via SSH after bootup.
Building and downloading applications
Navigate into the gcc subdirectory of one of the provided projects and run command make. On first run, you have to choose the platform. Enter the displayed ID for raspberry_pi.
maz@maz-VirtualBox:~/goal/projects/00410_goal/template/gcc$ make No platform selected, choose a platform - OR - press <CTRL+c> and set the PLATFORM environment variable. Choose platform: [ 1] linux_x86 (gcc) [ 2] linux_x86_clang (gcc) [ 3] raspberry_pi (gcc) Choice [1-3]:
Build process is executed afterwards automatically. The created binary is placed in the GCC subdirectory build/raspberry_pi/goal_raspberry_pi.bin.
Downloading the binary can be realized by scp for example. If the Raspberry Pi is already connected to the local network and its {IP} it is available, run the following command to copy the binary file into the home directory of the {user}
cp build/raspberry_pi/goal_raspberry_pi.bin {user}@{IP}:/home/{user}/
The GOAL protocol software is available as a 3h time limited demo release. In this case, the projects of protocol stacks are only available as library projects. These projects are marked by file ending _lib. Building and downloading the demo application is similar to the description above, but additionally, the library libgoal_raspberry_pi.so has to be copied to the Raspberry Pi too. The file is available in the 00_lib directory for each protocol stack.
Logging is always enabled in the libraries.
Starting applications
After downloading the binary file, the application can be executed. Please not, that you need root access to start the program. Changing to to super user by sudo su is recommended.
Subsequently, navigate into the directory where the application file is located.
If you are using the Demo version of GOAL, please set the LD_LIBRARY_PATH to the directory, where the libgoal_raspberry_pi.so is located like shown below.
root@maz-raspi:/home/pi# LD_LIBRARY_PATH=/home/pi/ root@maz-raspi:/home/pi# export LD_LIBRARY_PATH
Starting the GOAL application is done by simply executing the binary file. If your application requires a network interface, please use the argument -i to pass the interface name to your application.
See following example for a running a GOAL demo.
