OS Installation and Configuration (RPI)

These instructions will bring get your Raspberry Pi operating system set up and configured. Software install instructions can be found here. We provide an image for the Raspberry Pi for LoCO, which you can just flash onto the RPI yourself. If you have an image to flash onto the Pi, follow these steps:

• Raspberry-Pi:-Flash-Existing-Image-and-Configure

However, if you're building a new image from scratch, follow these steps:

Ubuntu 18.04 (Rev 9/22/20)

• Raspberry-Pi:-OS-Install-and-Configuration-(18.04)

Ubuntu 20.04 (Not Yet Supported)

Our current system is based on Ubuntu 18.04 and ROS Melodic, as Cannonical had not yet released official Ubuntu support for the Raspberry Pi 4 when we were initially building the LoCO image. Moving to Ubuntu 20.04 and ROS Noetic would be great, but it is not currently necessary, as Ubuntu 18.04 and ROS Melodic are still under support. We will eventually move to that configuration (likely during our build of a new LoCO robot once COVID conditions permit close work).

If you do complete this configuration, please write documentation during the configuration process. Once you have completed creating the image, please create a system image using whatever method you choose, then save it for later use.

Notes

• We are currently using a Raspberry Pi 4 (4GB), with Xubuntu 18.04. Other boards and OS's may work, but the instructions on this wiki only cover that specific hardware, and that specific OS.
• If you make a new image, make sure to save the image for future use. It's really easy for these MicroSD cards to get corrupted, so make sure you've got a backup.
