TODO: RTI Connext 6 Update

First Time Setup

https://www.raspberrypi.org/downloads/raspbian/

Install Raspbian Lite

Install and configure NTP

Install tmux, sudo apt install tmux

Install the RTI Connext libraries under /usr/local/lib/. This should be done after the ARM libraries have been installed. The required files can be found in opt/rti_connext_dds-6.0.0/lib/armv6vfphLinux3.xgcc4.7.2/ (copy the arm folder).

It should look like this afterward:

Make the libraries available. Insert /usr/local/lib/rti_connext_dds-6.0.0/armv6vfphLinux3.xgcc4.7.2 into /etc/ld.so.conf. Then run sudo ldconfig.

Copy the file git:software/vehicle_raspberry_firmware/bootloader_raspberry.bash to /root/bootloader_raspberry.bash on the Raspberry.

Enable autostart, using sudo nano /etc/rc.local and insert

tmux new-session -d -s "bootloader_raspberry" "bash /root/bootloader_raspberry.bash"

Edit the /etc/hostname file to give the Raspberry a unique name. The name should correspond to the vehicle ID, for example raspberrypi-06 or raspberrypi-42.

Create a DHCP reservation for the Raspberry on the router. The vehilce ID is derived from the IP. The IP is 192.168.1.1XX where XX are the digits of the vehicle ID.

TODO: Configure the system to be read-only (e.g. https://www.mehr4u.de/raspberry-pi-mit-readonly-filesystem.html) (comment as this is evidently the case but I do not know which method was used here).

Perform changes after setting the system to be read-only

Take a look at the rw alias in https://www.mehr4u.de/raspberry-pi-mit-readonly-filesystem.html (alias rw='mount -o remount,rw / ; mount -o remount,rw /boot'). This command can be used if you need writing access to the filesystem (using sudo).

Cross Compilation and Software Distribution

The vehicle Raspberry software is cross-compiled from the master PC. The build script git:software/vehicle_raspberry_firmware/build.bash creates an archive of the compiled software and other required files and publishes it via Apache. The bootloader_raspberry.bash autostart script on the Raspberry downloads and runs this software.
