Hi Mikhail_a 

Thanks for reaching out.
May I ask the following to help us understand the issue:

  1. Could you attach the AXI MCDMA .ip file so we can review the parameter settings?
  2. Which design example variant and which driver did you use?
  3. Is the issue first observed in Q25.1, then in Q25.3.1? Did it work correctly prior to Q25.1?
  4. Are you using an Altera Dev Kit or a custom board?
  5. Could you share the STP when the issue occurs?
  6. Could you provide the exact steps to reproduce the issue?

 

Thanks.
Best Regards,
Ven
