$ cd FastRTPS-2.0.0
$ mkdir build && cd build
$ cmake -DTHIRDPARTY=ON -DSECURITY=ON ..

Clone & build PX4-Autopilot from rudislabs repo

$ cd ~/src
$ git clone --recursive https://github.com/rudislabs/PX4-Autopilot.git -b pr-cupcar
$ cd PX4-Autopilot
# Add nxpcup to PX4-Autopilot/boards/nxp/fmuk66-v3/rtps.cmake under EXAMPLES #
$ make nxp_fmuk66-v3_rtps
# Flash your FMU using rtps binary #

Setting up NavQ

Run setup script to install ROS2 Foxy and microRTPS

FTP the zip file linked below to NavQ, then unzip using

10KB
Binary
navq-install
$ unzip navq-install.zip
and then run the script inside using
$ ./navq-install/navq-install.sh

Install ROS2 camera tools

Install ROS2 camera tools so we can publish camera data to the /image topic. Use
$ sudo apt install ros-foxy-cv-bridge \
ros-foxy-image-tools \
ros-foxy-image-transport \
ros-foxy-image-transport-plugins \
ros-foxy-image-pipeline \
ros-foxy-camera-calibration-parsers \

Clone and build `nxp_cup_vision`

Clone nxp_cup_vision and then build it using the commands below
$ cd
$ mkdir ros2src
$ cd ros2src
$ git clone https://github.com/rudislabs/nxp_cup_vision.git
$ colcon build --symlink-install
Once that is done, source the setup.bash file
$ echo "~/ros2src/install/setup.bash" >> .bashrc
You should have everything installed now.
