I've made a construction with iMX6 solo based on the Sabre SD development board. It looks like I'm not going to need some regulators from the PF0100, for instance VGEN1 and VGEN2. I assume their outputs should just be NC then? Also, this implies that I do not need to connect any supply to VIN1 (which powers VGEN1 and VGEN2). Is this correct? Can I just leave VIN1 unconnected and connect VIN2 and VIN3 only?
