Hello,
I use quartus II 4.00 and SOPC builder 4.00 to build a NIOS system on a Stratix II board. I enabled the support for external interruptions, add a user defined IP connected via the provided avalon ahb bridge. Everything is ok. Then I try to use the interruption of the bridge, everything on the wire is ok until the data_master_irq gets high. The iq number is ok, NIOS makes a couple of instructions more and then stops on a strange adress (totallly out of the memory map). but it doesn't fetch the ISR code indeed. The soft uses nr-installusr and is exactly the same as the examples provided. I tried whithout any soft isr and initialisation to see if i get the famous message ... but nothing. How can I be sure of what is done by the compiler, is there any restriction that I don't respect ? thanks for all your help and experience about those interrupts on NIOS systems. Sincerely Julien ChevalierLink Copied

Humm....
For fun... Try assigning the IRQ you are having a problem with to a different number in SOPC Builder. Regenerate, do another Place and route and see what happens then. Seems kind of strange that you are using an avalon to AHB bridge. hbutler97- Mark as New
