@Lazar-Demin : Thanks a lot. It took us some time to finalize this dev :-). Correct: The MicroSD only is accessed by the display controller. However, over serial commands from the Omega to the display controller, you can interact with the display itself. I'm pretty fond of this, as just dumping some serial commands really is easy. I therefore have two MicroSD slots on the board. One is reserved for the display controller and only accessed by it. The second one is connected to the Omega2S+ and serves as memory extension. If this can be an interesting solution for you, don't hesitate E-mailing me. I'll send you a proto board. Best, MK
