So what is the lay of the land with the Yellow cube? Is it still not fully supported? When NOT connected to Mission Planner, I am able to install the firmware on it. I only tried Plane, Copter, and Rover. These installed ok, but, once the install was complete, and I attempted to connect to Mission Planner (on the corresponding port and speed), it refuses to do so and time-outs. Cube Black, Orange, and Blue work fine but Yellow refuses to do so. I tried multiple computers (WIN and MacOS) and tablets, and the outcome is the same. Is it maybe a bad Yellow Cube?
