STM32H743 nucleo won't work in USB OTG FS

Hello,

I am working on a STM32H743 – NUCLEO 144 and need to use OTG_FS device only option in CDC mode.

I generated a project using the stm32cubeMX and have defined:

1. SYS – Time bases : TIM1
2. USB DEVICE – class for FS IP: CDC
3. USB_OTG_FS - device only, VBUS – disabled
4. The clock is configured from RC48 to USB
5. Last cube version – 4.23

Found 2 problems:

1. The device won’t enumerate as a serial com port and I cannot see it as unknown device as well (I am talking about CN13).
2. The interrupt OTG_FS_Handler, never fires. So nobody raises HAL_PCD_IRQHandler.

As a test, same steps (using the cube) were applied on STM32L496 – nucleo, the L4 board enumerates and works properly as usb OTG.

Did someone encountered these problems on STM32H7?

What am I missing?

, I saw your question about the stm32H743 USB, did you manage to run the OTG FS CDC mode?

Thanks for the help!

I connected to CN13 (OTG CABLE ) - from that interface i could get in terminal program data, and configuration of speed of VCP i could'n to see.

P.S. In stm32F4 discovery board i finded place for changing beatrate for VCP. Now, i need to find that in Nucleo H743 board.
