Raspberry / Traffic Light Application

Steps for building the traffic light application:

1. (Get a Debian based host system, we used Ubuntu 16.04)
2. Get the Linaro toolchain for ARM gcc-linaro-4.9-2016.02-x86_64_arm-linux-gnueabihf
3. Extract it somewhere
4. Look into the build script Raspberry_App/toolchain-build/cross-compile-libs.sh
5. It has no error checking, so it’s not meant to be run as a whole.
6. Adjust the parameters at the beginning according to your system and run the commands one by one.
7. You should now have a Raspbian image in /tmp. Store it somewhere, where it won’t get deleted
8. Use Raspberry_App/toolchain-build/mount-raspbian.sh to mount it
9. Use CMake for building:

   cd Raspberry_App/TrafficLight
   mkdir build && cd build
   cmake -D CMAKE_TOOLCHAIN_FILE="/path/to/rpi-toolchain.cmake" -D PIROOT="/path/to/rasp-pi-rootfs" -D TOOLCHAIN="/path/to/gcc-linaro-4.9-2016.02-x86_64_arm-linux-gnueabihf" ..
   make
   

• For the configuration of Wifi (password), network etc. see cross-compile-libs.sh
