    CY7C67200 Co-Processor Mode as Slave USB device

    joseph.lakeman

      Hi. I'm wondering if anyone can help me with either an exmaple or understanding how this thing works?  I am having trouble trying to program the chip over HPI in co-processor mode.  If I bypass the CY16 processor then I'm able to read a setup packet from memory.  However, when I try to reply to the packet, I don't get a response. The chip just sits in an infinate loop of bus reset, setup packet (get descriptor).

         

      If I allow the CY16 to handle the descriptors then I run into a problem with vendor setup packets. I don't know how to program the CY16 to allow me to reply, or load replys into memory.

         

      Any help would be greatly appreciated..
