Honored ContributorI had all sorts of fun trying to get those controllers to work. I ended up writing my own Avalon-MM width adapter for the dispatcher, it seems the Qsys generated interconnect was causing all sorts of problems (maybe a glitch in Qsys?). That got it to sort of work, but in the end I just ditched them as they were proving quite flaky - sometimes working, but then locking up for some unknown reason. (I've been slowly ditching most of the Altera IP cores from my designs as they seem to be more trouble than they are worth).
In the end I wrote my own DMA controller, which to be honest I should have done in the first place, I was just being lazy at the time.
