I'm trying to develop an USB 2.0 OTG interface with a FPGA (Xilinx or Altera). Therefore I think I'll have to make some sort of IP with UTMI(+) or ULPI interface to communicate with an external PHY. As PHY i was thinking about the ISP150x frow Philips or the USB3300 from SMSC. Maybe someone else better suggestions? Buying a IP is expensing if you're not planning to make lots of the product, unless there is a free USB 2.0 OTG IP-core.
I also need a development/evaluation kit. I found a few interesting boards: hydraXC with the LEEB or the one from asics.ws. Wich one can you recommend?
Hope you can help me.
