Hii all,
I am trying to develop a USB host controller on vertex4, for that i am using xps usb host ip core. I am facing problem in configuring the ports of the ip core, like there are several options like
MD_Error
Port_Indicators[1:0]
Host_Intr_Out
(BUS_IF)MPLB
(BUS_IF)SPLB
(IO_IF)usbhost_0
USB_PHY_Reset
ULPI_Clock
ULPI_Dir
ULPI_Nxt
ULPI_Stp
ULPI_Data_I(7:0)
ULPI_Data_T(7:0)
ULPI_Data_O(7:0)
ULPI_Data(7:0)
which have options to be configured as "no connection, make external etc. " It will be really helpful if anybody who has worked on this can share something. I have gone through the EHCI and ULPI protocols but am not able to make much out of it.
thanks in advance.
