USB OTG MSC in STM32 discovery

Adeesha Savinda de Silva

I have been following a tutorial by Ralf Kopsch in youtube. I am facing a trouble in USB OTG MSC configuration for STM32F4-Discovery (STM32F407VGT6) board. The function finit(drive_name) returns fsDriverError status. I was cofiguring it in the Full Speed (as only available in the board).

Can I find a tutorial or at least a sample project which configures STM32F4- Discovery board with new CMSIS HAL libraries (as available projects with DFP is not cofigured in HAL)?

Or if anyone can guide me in configuration steps?

This would be a great help :)

Thanks
Adeesha
