13.2 EDK - How to access ULPI UPAR registers on USB2 Device


How can I access the ULPI/UPAR registers on the Xilinx Platform Studio (XPS) USB2 Device or the AXI USB2 Device?


The XPS version of the core will not have this ability until core version v7.00.a
The AXI version of the core has the feature added as of v2.00.a

Details on how to use either of these is described in your<XILINX_INSTALL>\ISE_DS\EDK\sw\XilinxProcessorIPLib\drivers\usb_vN.NN.a\doc directory. This feature was added with driver v4.00.a
