I have the following problem on a Virtex5 system: I use an interrupt controller, that is connected to the PPC interrupt port. The interrupt controller and the PPC interrupt handler are initialized but working ONLY for the very first interrupt. After the first interrupt occured the processor hangs at address 0x60, which is in the interrupt vector table:00000060 : 60: 7c 70 43 a6 mtsprg 0,r3 64: 38 60 00 06 li r3,6 68: 7c 60 43 a6 mtspr 256,r3 6c: 48 00 00 94 b 100
Did I miss something about the initialization? I used the source code provided with the examples of the xps_intc.
