OLD Bare Metal System Image

This page will guide you through the steps to install a basic system image.

On this image you will have the ROS base system, the OpenMower installation, local configuration for your mower and some tools to help you work with the mower.

Prerequisites

In order to follow this guide, you will need the following:

1. A Raspberry Pi 4 (4GB or more recommended, 2GB works with swap, see below)
2. An SD card
3. A soldered OpenMower mainboard

Installing the Base System

The first step is to install the base system. We're using Ubuntu 20.04 Server for the Raspberry Pi. This is, because this image gives us best support ROS Noetic.

Installing the base image is easy:

1. Get the Raspberry Pi Imager software [1]
2. Select the correct operating system: Other-general-purpose OS > Ubuntu > Ubuntu Server 20.04.4 LTS (RPI 3/4/400)
3. Insert your SD card into your PC and select it in the Storage part of the software
4. Click write and wait for the process to finish

Once you have successfully flashed your image, remove the SD for your PC and reinsert it again.

Then replace the /boot/config.txt file with the one provided here: [2]

This will enable all hardware serial ports on the Raspberry Pi.

Once you have done this step, you can eject the SD card and plug it into your Raspberry Pi 4.
