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.
