Honored Contributorim also having the same kind of problem..
the memory test program example (provided in nios eds) stuck at "-testing memory using dma".unfortunately i didnt see anybody reply to your thread.. and i know this is an old thread, but have you found the solution to it? Im stuck with it like two weeks now finding the solution. please guide me through this if you or somebody else has already solved it. I dont believe its a physical hardware problem of the memory chip since the bits testing of the sdram does work.. Only the dma didnt work. Seems like it never got the "rx_done" into '1' since the transfer does not complete. I wonder why.. here is the screen shot of my sopc: https://www.alteraforum.com/forum/attachment.php?attachmentid=2382 i tried to attach my full system but its too big. sorry BTW im using Altera 8.0 version software.
