Hi, I am using STM32F205 to interface ULPI PHY(CY7C68003), but the USB interface doesn't work.
Please tell me how to read/write the registers of CY7C68003 through STM32_USB-Host-Device_Lib or STM32Cube_FW.
Thanks a lot!
AFAIK, there is no "officially documented registers" that allow you to access ULPI PHY registers.
However, it looks there are some hidden secret registers for that purpose (at least on STM32F7).
Please take a look at below source code within CubeF7, you can find USB_ULPI_Read() and
Sorry, but I don't know STM32F205 has those secret registers or not.
