Hi I am using the STM32F7 MCU to use a usb. I can get the USB connected however, when I try to run debug, the application hard faults, and I can't trace the error. I was hoping to get a reference to a tutorial from STM regarding reading/writing to USB. I have the pinout configuration correct. I am using USB_OTG_FS Host Only, Mass Storage Host Class. In FATFS I adjusted the parameters USE_LFN to be enabled with static working buffer on the BSS, I disabled FS_REENTRANT.
