FPGA to HPS Communication

Hi ,

Thanks for the answer :)

Should I use the Nios ii for this ? . My design actually scans some GPIO ports from the board and I have convert it into a file. For this I have to transfer these data chunks to the RAM and access from Linux. So I have already a small VHDL module scans the ports and put these data into a FIFO. Now I have use DMA to transfer the data to RAM.

Is it possible to use without Nios ii ? I mean with the DMA ip , is it possible to write a small VHDL module and send data to the memory via this IP through DMA?

Do you have a link /tutorial with minimal example with DMA , both hardware and software ? Its ok if it is with Nios ii

Best Regards.
