Hi,
In order to keep VisualGDB price competitive, we only directly support the most popular devices and offer various customization mechanisms to allow our customers to easily add support for the devices that are not directly supported.
The easiest way to create a project for an unsupported device is to follow our legacy device tutorial.
Our BSP generators on github have a very basic Wiki page that outlines the basic concepts, but generating a full-blown BSP would much harder than just setting up a manual project (and exporting it to a template).
We also provide a service for creating BSPs for rare devices on demand, so if you don’t want to go through this process yourself, feel free to contact our sales to get a quote for a custom BSP.
