Every SoM comes with a makeshift Linux system. Every manufacturer must add OTA updates, security measures, remote access, GUI frameworks and more. That's a lot of duplicated work. This would be much more efficient, if a SoM maker provides a Linux with all the features ready for use by manufacturers. Toradex does this with Torizon. We show how manufacturers can benefit from this groundwork with minimal effort. Torizon even runs on non-Toradex SoMs. SoM = Solutions on Module.
The Yocto recipe gives GPL as the license of MariaDB. The Qt Sql library implements its MySQL driver with MariaDB. Hence, it would be under GPL - and so would be all applications linking Qt Sql. Businesses would have to open-source their code. A disaster! So, what's wrong?
