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

   

                                                      0x1088800

   

                                                      0x2088800

   

                                                      0x4088800 

   

                                                      0x8088800

   

                                                      0x9800000

   

attached are the firmware and my  asynchronous transfer code.
