STM32H743 nucleo in USB OTG FS with internal DMA

Hello,

 

Trying to create a USB with internal DMA using the CubeMX for the H743 nucleo, not luck so far.

It works fine without the Internal DMA!

 

I set the Enable internal IP DMA to Enable in the Cube and now the device won’t enumerate.

What is missing to enable the internal DMA of the usb?

 

I looked at the LwIP_HTTP_Server_Netconn_RTOS example and USB_Device/CDC_Standalone (that uses HS CDC with UART and DMA ) example but I am new to the DMA subject.

Can anyone point me in the right direction? 

 

Thanks!
