ULPI PHY issue with STM32F429

Hi All,

I have a USB3333 connected to a STM32F429. I can't seem to get the PHY to enumerate in high speed mode - it always falls back to full speed. My code is using the ST cube example with minor modifications (pin changes etc).

After doing some digging I have found some other posts that refer to issues with F4xx micros and some SMSC PHYs (here and here and possibly here). There is nothing official from ST that I can find anywhere. There is nothing in the latest errata.

Does anyone have any information on this?

Can anyone from ST provide a comment please?

I would be very grateful for any information.

Thanks in advance.
