ChibiOS Free Embedded RTOS

Hello,

I have some problems to run the USB Driver with ULPI on STM32F446.

The same code ( except that the ULPI_D4 pin change ) run perfectly on a STM32F427 ( I use the same board but swap the mcu)

Does anyone have run the ULPI driver on STM32F446 with success?

Thanks !

Hi,

Never tested on that device because lack of HW. It is possible there are differences in the OTG peripheral related to ULPI, it has been updated in newer devices.

Ok thanks,

I will keep the 427 for now and check what happens on 446 in few weeks. I will keep you in touch.
