Hi, I’m working with rasspberry pi 5 and hailo-8l on it. I have installed Ubuntu 24.04, converted my custom model to hef format and am doing object detection. It works, but then I need to connect ROS2 to it. Please tell me which version of ros2 is better to work with and how to install it correctly.
My rpi-5 has hailort and its drivers version 4.19 and tappas version 3.30.

Hey @vlad.purhin,

Here’s how to set up ROS 2 on your Raspberry Pi 5 with Ubuntu 24.04 and Hailo-8L:

  • Install ROS 2 Iron Irwini
    # Add required repositories
sudo apt update && sudo apt install -y software-properties-common
sudo add-apt-repository universe
sudo apt update && sudo apt install curl -y

# Add ROS 2 repository
curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.key | sudo apt-key add -
sudo sh -c 'echo "deb [arch=arm64] http://packages.ros.org/ros2/ubuntu $(lsb_release -cs) main" > /etc/apt/sources.list.d/ros2-latest.list'

# Install ROS 2
sudo apt update
sudo apt install ros-iron-desktop

# Set up environment
echo "source /opt/ros/iron/setup.bash" >> ~/.bashrc
source ~/.bashrc

Notes:

  • ROS 2 Iron Irwini is recommended for Ubuntu 24.04
  • This setup includes the full desktop installation
  • The environment will be automatically sourced in new terminals

Let me know if you need help with anything specific!

Hello @omria,
Unfortunately, at the installation stage, I get an error because of packages that are not available to me. I searched the internet and found in the official documentation that ROS2 Iron is currently available for Ubuntu 22.04.
