Hello,
i'm currently triing to get an opb-timer to work. The timer is connected to the ppc via an opb-interruptcontroller. I was (exactly) following the Xilinx-Tutorials (Chapter "Memory-Management" in the Embedded Systems Tool Guide). The problem is i won't recieve any interrupts generated by the timer. When connecting the timer-interrupt-output to an led, the led stays off. I tried different combinations:
- with / without intermidiate interruptcontroller
- with dynamic-handler-registration (per programming-API) / with harded interrupt-handler-registration in system.mhs
Finally i took the example c-sources supplied in the memory-management-chapter and compiled/executed them with an appropriate edk-design (i was adding the neccesary components and renamed the instances, so that no additional changes to the sources had to be made, system.mhs and system.mss were edited accordingly).
But even with those examples provided by xilinx i wont get the timer to work. At the moment i've got ne idea what could be the reason. I'm using EDK6.2 and a Virtex2Pro (P7V2) Developement Board (Memec-Design).
So if anyone has had similar problems i'd be very thankful for a hint. Regards Patrick Siegel
