What's the difference in baremetal libs: xusb & xusbps?

Jump to solution

I am using Xilinx SDK 2015.4 with Zynq.

In my installation, the baremetal API libs are found at:

.../Xilinx/SDK/2015.4/data/embeddedsw/XilinxProcessorIPLib/drivers/

which includes usb_v5_0 and usbps_v2_2.

 

Anyway, what is the difference between them? Is there some amount of overlap?

usb says it is the driver for the USB device controller (first release Feb 2007).

usbps says it is the driver for the USB controller in device and host mode (first release Oct 2010).

hi,

 

xusb is the driver for AXI USB2 Controller that can be implemented in PL. This is for soft controller.

xusbps is the driver for PS USB controller that is included in the PS of Zynq.
