STM32F415RGT6 Internal DMA configuration support.

[S_Srinath]

Hi,

I am trying to use internal DMA configuration on STM32F415RGT6. Couldn't find the relevant support for enabling the dma and also watching off the dma transmit and receive flag as an Endpoint mode. The STM is operating as an Endpoint device. I am trying to send BULK IN. Existing doesn't have the internal DMA enabled. It is waiting for the entire Data to get transmitted. I need to use DMA for USB to perform parallel data send and resume other operations we have in our application.

Hi @S_Srinath 

Did you make sure to consider data alignment? (by multiple of 4 packet). In fact, internal DMA doesn't allow sending data from non-word aligned addresses.
