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/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.
