Hi,
Attached an example of DE-2 try to go through it and implement for d2-115.
Also look into example below for d2-115 without on chip ram which can be modified.

  Hi @rkaib ,
  Memory overflow issue.
  Increase your onchip ram(onchip_memory2_0) size in QSYS System design.
  Which will solve the problem.
  Let me know if this has helped resolve the issue you are facing or if you need any further assistance.

    Hi,
    I have used onchip ram in your project, Please check attached.
    Create your own eclipse project and check.
    Note : Not tested
