Further research, looking at the Eagle board and schematic files for the PB, it appears that USB0.VIN and USB1.VIN are both directly connected to VIN.USB Which explains why I had no power on my USB1 host port when connected like the Fritzing diagram, since I am powering from VIN currently.
So the question becomes,,, What is the best way to power USB1 VBUS as a host if I don't know in advance whether the customer application will run from VIN or VIN.USB? --- Graham == On Sunday, November 5, 2017 at 6:58:06 PM UTC-6, Graham wrote: > > I note that there is a PocketBeagle pin P1-7 named USB1-VIN. > > I don't find any connection on the PB schematic, other than to P1-7. > > It was connected externally in all of the USB1 host discussions and > Fritzing diagrams. > > The name would imply that it is a way to deliver power to the board when > USB1 has an external 5 Volt power source. > > I guess the basic question is whether this needs to be used/connected when > USB1 is functioning as a host. > > --- Graham > > == > -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
