GD32F407VGT6

[cqyp223]

Hello

I use this library on STM32F103, STM32F401 and STM32F429 and it works very well. I tried to run USB in device mode on GD32F407 using the usbd_stm32f429_otgfs.c driver and it just doesn't want to work. The device is not detected by the PC, the D+ line is not pulled up. The same program (binary file) uploaded to the STM32F429 processor (NUCLEO board) works without a problem.

Would it be possible to add a driver to support GD32F407 processors?

Best regards
Łukasz
