      Hi Eliath,
      I am interested in the 2nd design (FPGA DDR)which you mentioned.
      I went through the design provided by you . But I didn't find the c code( NIOS eclipse code) which is used to store data in DDR .Am I seeing something wrong?
      I just want to understand (code wise) how data is written to FPGA DDR using Eclipse c code.
      Please guide me.

      Thankyou
      Regards
      Yogesh

    Hi Yogesh,

    Hoping you're doing well, I wonder if I can close this thread,

    I found another post of you with almost the same question and I've seen

    my colleague gave you a solution.

    Is there anything else I can do for you?


    Best regards,
