    Reading sequential data from Streaming in

    kaiyu.lin

       Hi!

         

       

         

      I'm testing the streaming in firmware on the FX3.

         

      Using a fifo 32 bit interface between Spartan 6 FPGA and FX3,

         

      i'm trying to read a simple counter inside the FPGA from Control Center.

         

      What's troubling me is that, after resetting both FPGA and FX3, when I press "Transfer Data-IN",

         

      the first 32 bit I read is different from 0.

         

      This lead me to think that as soon as I program the FPGA it starts to count and write into FX3 DMA buffer.

         

      How can I read sequentially the counter avoiding data loss?

         

       

         

      Thank you!
