    CY7C68013A packet loss regularly


      Recently, I have met a packet loss problem with the bulk asynchronous transfer from fpga to pc(16Mbps).


      conf: bulk IN ; ept 6;  maxpacketsize = 512; slave fifo mode.


              with the data goes form 0x0000 to 0xffff as a cycle, I set the  asynchronous data get length once as 512 * 256. Data loss when the data number reach  0x8800












      attached are the firmware and my  asynchronous transfer code.
