[Murat Demirtas]

Hi friends,

            I have read a lot document about booting orange pi zero over usb flash. I flashed latest mainline u-boot to orange pi's SPI Flash. I can boot the system via the usb port which is next to the ethernet. Can I boot the system via the usb ports USB2 and USB3 that the h2+ has and the expansion card that can use it?. I can not see these USB's through u-boot terminal. thanks.
