Hello.
I want to use USB HS with the STM32H755ZI-Nucleo Board. I am using the USB3300 from Waveshare as an external USB HS-PHY.
The USB3300 is connected to the ULPI Interface of the STM32 with the requiered 12 Signals. And the USB3300 provides a 60 MHz Clock.
My question now is, how do I configure the RCC correctly? Should I use HSE in bypass mode? Is the 60MHz from the USB3300 then correctly provided to the STM32?
Or do I need to solder a external oscillator with 25MHz that I use for the STM32 setup?
Unfortunately I can not find any information on High-Speed USB other then connect them to the ULPI.
I wanted to use a Clock Config like this:
Right now I thought I can use HSE as BYPASS Clock Source, but the USB Communication is not working.
So do I need to solder external Oscillator or is this Clock Config useable for USB HS?
Thanks in advance,
Alexander
