The tutorial files are located here:ftp://ftp.altera.com/up/pub/altera_m...2.0/tutorials/ (ftp://ftp.altera.com/up/pub/altera_material/12.0/tutorials/) I can't attach the Qsys system, but I can attach a screenshot of it.... The problem is the ISR never gets called to receive the packet... It does appear to send though here's what shows in the debug window: Opened scatter-gather dma transmit device Opened scatter-gather dma receive device send> TEST1234TEST TEST1234TEST send> There should be a receive in there, but I can't figure out why... the Qsys and QuartusII part of the tutorial built without errors... I'm guessing that something isn't hooked up correctly in the Qsys picture... Thanks.
