STM32F415RGT6 USB HS in Internal DMA mode.

Hi,

I am trying to use the internal DMA mode on USB_HS as a device mode. Can I get relevant USBD_LL_x api's which support it. And a sample example code which uses this DMA bus for configurations.

 

Thanks,

Srinath

Hi @S_Srinath 

Are you using custom board with external PHY? AFAIK, we don't provide an example for High-speed operations in DMA mode on F4. You may check this article How to correctly setup your application to use USB... - STMicroelectronics Community.
