2008-04-16 16:15:57 Using ULPI to build a Blackfin based USB controller?
Anders Marten (SWEDEN)
Hi, I am a novise in this area. But in my struggle to lower the cost of my Blackfin based design I have stumbled over the ULPI specification that makes it possible to implemet the bulk of the USB logic in an ASIC, FPGA, or CPU - or am I wrong?
Do anyone have any experience from using ULPI on the Blackfin to remove the cost of the external USB controller?

When I poked around on the http://www.ulpi.org/ web site - I could not find much that had been updated since 2004. I think it is dead.
As well - you still need specific IP inside the chip that the Blackfin does not have.
If you need USB, (assuming that you can use OTG) look at the BF54x or BF52x.
