Honored ContributorHi everyone,
I have added my own customized component "Dual FIFO" in SOPC builder. I have kept its priority 0 to ensure it has top priority. I have programmed in such a way that every 2 milli-sec an interrupt will come to NIOS II. In my NIOS II application program, I registered the interrupt and written ISR. Everytime an interrupt comes, ISR gets executed. BUTTTT after some time ISR doen't get executed or I can say my system doesn't respond. I experimented and calculated that ISR runs for fix number of times 14563 and stops after this. What might be the reason ? Please reply... URGENT !!!!!!!!!!
