I am writing the software for the PPC405 embedded in a V2pro.

I have an OPB Intc Interrupt controller and am having trouble getting it
going.

I know it's at the memory locations expected as the IVR contains all ones
and
all other regs contain zeros. Also, I cant write to any reg until I have set
the ME
bit is set which tells me that it is att least doing something.

I am tryin to do the old Enable Interupt , Set Interupt, Acknowledge
Interrupt test
but the ISR is not being cleared by the acknowledge.

Any other suggestions ????????

Cheers
