DMA controller intel fpga IP not working. Its qsys GUI , its documentation is confusing.

Hie, I will need more details as below. In general the DMA controllers offered by Intel FPGA's reference designs have been validate to be functional. Hence, if you are using the correct reference design, it will at least show some activity. I am also not familiar which file you go the above code from. Hence, please check if you can provide the following information for me to assist you: i. FPGA device (Arria 10, Stratix 10 or?) ii. Confirm Interface type used is AVMM-DMA iii. Gen and width iv. Quartus version used v. Where did you get the reference design? Regards, Nathan
