ChibiOS Free Embedded RTOS

Hey there,
I am working on a external USB HS PHY (USB3300) on STM32F405. The board is my own PCB with no HSE installed. I modified
// in mcuconf.h
#define STM32_USB_USE_OTG1 FALSE
#define STM32_USB_USE_OTG2 TRUE

// in board.h
#define BOARD_OTG2_USES_ULPI

I also configured the GPIO pinset ...

I got confirmation of ULPI working on STM32H743 on Discord, there must be some missing detail in your setup.

Ok, thanks a lot.
I'll check my config again.

Hi,

The one with HS should be STM32_USB_USE_OTG2 (which internally uses OTG_HS as defined in ST headers). The board file must define BOARD_OTG2_USES_ULPI.

Which board are you using? there could be a problem in clock settings and/or GPIO settings.

Hey there,

I am tring to use a USB PHY ULPI module to run USB HS on STM32H750 chip with ChibiOS.
After configured
#define STM32_USB_USE_OTG1 FALSE
#define STM32_USB_USE_OTG2 TRUE
#define STM32_USE_USB_OTG2_HS TRUE
// ...and...
