We are building a board using STM32H750VB and I need to connect a USB connector. I thought of using OTG_HS. In this type many signals related to ULPI and OTG_HS_SOF are available, which I don't need. So I need to know whether these signal are mandatory to use OTG_HS or not.
If you are using the internal (FS) PHY, then only the DP/DM pins are needed. If you're using an external PHY, then you'll need to connect all ULPI pins.
