    I can't send a file more than of 1MByte for USB



      I have connected the USB controller with a Spartan6 FPGA, I have configured this connection for can to initialize the FPGA from PC USB interface with CY7C68013A, I send the bitstream through USB controller. The problem start when the driver hang out it always after in 1Mbyte transfer.


      In other case the same interface with old FPGAs with SPARTAN3,SPARTAN2, VIRTEX4, don't need more than 1MByte bitstream and I haven't any problem with them.


      I dont know which are the problems?  had you had any same problem? and which are the solutions?








      Best regards
