    Data loss during tansfer

    yu.hongyu

            CPLD--->CY7c68013--->PC

      CPLD generates incremental data, then I use BULK method, EP2 out, EP6 in,to send

      data to PC, PC use bulk-loop function(Cypress Examples, i modified this VC++ code, to force PC to receive only),

      I use BUSHOUND to watch the data , I find data loss during data transfer. some data

      loss per 512 bytes transfer.

      Need I use ping-pong transfer? How to realize it.....

      I beg your reply......
