About OTG connector

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 mandato...

Resolved! Why are PC8 and PC9 not connected on the Morpho connector of my NUCLEO-H743ZI2?

As per UM2407, page 42, PC8 and PC9 should be Pins 1 and 2 of the CN12 Morpho connector. On the silk screen on the board the corresponding pins are labeled accordingly as well.However on my NUCLEO-H743ZI2 board I can not get a signal from the MCU on ...
