CPU IRQ 0 of PowerPC405

Hi,

I have to handle the CPU IRQ 0 interrupt of a MIP405gp board.
Is this interrupt still assigned to the vector number 25 ??
I’m using the binary BSP for the Walnut board …

Regards

Yes, PPC405 external interrupt 0 is mapped to QNX irq 25.

Yes, PPC405 external interrupt 0 is mapped to QNX irq 25.

Thank you. That makes it possible to handle the interrupt controllers of
the South Bridge of the MIP405 board in my interrupt handler of my
resource manager (just as an intermediate solution until a BSP is
available:) )
