Currently, only the PIO mode is supported. This add support of CPPI 4.1 to DA8xx. As in DA8xx the CPPI 4.1 DMA is a part of the USBSS, create the CPPI 4.1 device as a child of USB.

Say Y here if your system has a dual role high speed USB

controller based on the Mentor Graphics silicon IP. Then
|
|
configure options to match your silicon and the board
|
|
it's being used with, including the USB peripheral role,
|
|
or the USB host role, or both.
