Summary

The Zynq® UltraScale+™ MPSoC USB 3.0 controller consists of two independent dual-role device (DRD) controllers. Both can be individually configured to work as host or device at any given time. The USB 3.0 DRD controller provides an eXtensible host controller interface (xHCI) to the system software through the advanced eXtensible interface (AXI) slave interface. An internal DMA engine is present in the controller and it utilizes the AXI master interface to transfer data. There are four primary types of communication defined by the USB protocol, based on which any required application can be built without changing the firmware or underlying hardware for different applications. These transfer types are Control Transfer, Bulk Transfer, Isochronous transfer and Interrupt transfer. Zynq® UltraScale+™ MPSoC USB3.0 controller supports all four types of transfers.This Tech Tip explains how to enable all the configuration options, step by step procedure to use the Zynq® UltraScale+™ MPSoC USB 3.0 controller in device mode and make use of bulk transfer type for mass storage device using the USB 3.0.
