Building a Linux image for NavQ

HoverGames-Linux Distros

We have two separate Linux distributions that you can build for NavQ. There are pros and cons to both.

[1] HoverGames-BSP

The HoverGames-BSP image is based on NXP's Yocto BSP for i.MX 8M Mini. This distro is not as easy to use, and requires much more effort to get a working system, but currently it is the only system that is allowed for use if you want to use NavQ commercially. If you need tight integration and a small system that has only the packages you need installed on it, or if you're a company looking to use the NavQ in production, this is the one for you.

[2] HoverGames-Demo

The HoverGames-Demo image comes with the APT package manager as well as some other pre-installed software specific to i.MX 8M Mini. This distro is the easiest to use due to it's great compatibility with pre-existing binaries coming from official repositories. You can install ROS, OpenCV, and more on this image just as you would on a normal desktop computer. This makes the Demo image great for quick development and iteration. To use this image, you must agree to a Demo license stating that you will not use NavQ comercially with this distribution.

Building the Linux images for NavQ


You'll need to use a computer with Ubuntu 18.04 installed, and we recommend a high amount of cores + RAM to build these images in a decent time frame. You will also need a large HDD or SSD (>500GB) to store the build files. A table of recommended specs are below:

Install Yocto build tools

Follow the guide at Yocto's website to install the necessary build tools for Ubuntu/Debian, or just install the list of packages below:

$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \
     build-essential chrpath socat cpio python python3 python3-pip python3-pexpect \
     xz-utils debianutils iputils-ping libsdl1.2-dev xterm

Running the build script

We have a GitHub repo with instructions for both the HoverGames-BSP and HoverGames-Demo images. The BSP image can be built using the master branch, whereas the Demo image can be built using the demo branch. The link to the repo is below.
