Dear all, i have a problem with my custom board based on STM32H745.
I need to use core M4 with USB_HS host with mass storage class (a pen drive) at 12Mbit full speed (internal Phy transceiver).
I have configured the processor as per attached file (core M4, FatFS, USB host, 48MHz RC clock for USB).
The problem is that the FATFS Applistate variable is always in "application start" and never became "application ready". So that USB pen drive can not be mounted.
Previously, I succeded in use the FATFS pack with the same functions configured with core M7, but I want to use core M4 because I need it in my project architecture.
Consider that with the same FATFS pack I'm able to use SD card on the M4 core.
I can't figure why I'm not able to migrate the USB HS host from M7 to M4.
See also attached the function where the USB Host should be recognized and configured to receive data (in my project microSD card store datas and I want to download it to pen drive)
