PPC440 hangs after first interrupt

by Matthias Alles <REMOVEallesCAPITALS@[EMAIL PROTECTED] > Jun 24, 2008 at 05:11 PM

Hi!

I have the following problem on a Virtex5 system:
I use an interrupt controller, that is connected to the PPC interrupt
****t. 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 <IVOR6>:
  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 <non_critical_irq>

Did I miss something about the initialization? I used the source code
provided with the examples of the xps_intc.
