Hello i am trying to do the same thing that you did, but i am kinda new to software development for NIOS. And i would like to get a "start point" i've read a lot of altera documentation but i can't find a simple "read from a memory" and "write in another memory" design/tutorial with the hardware and the software.

I made a system consisting of a SDRAM, SGDMA and a NIOS. I want to write something to the DMA and that the dma writes the same data to the SDRAM.

DO you have any piece of sw code that do something like that? Thanks a lot.
