Hi, I'm working on a project based on a Xilinx Ultrascale+. The final board will contain, for JTAG interface, a SMT2-NC device with a USB type-C receptacle. This board should work as "device", and so as Upstream Facing Port (UFP). At the moment, I know how to treat the CC lines (via 5.1 kOhm pull-down resistors) but I still don't understand how to connect (or how to use) the VBUS lines, because the SMT2 is powered from the 3.3V and VREF pins and not VBUS.
Can I leave the VBUS lines unconnected or I should follow some specific procedure to connect them?
