Hi,
With my current flow, when I am asserting legacy nIRQ I am able to jump to ISR, but not when asserting IRQS[0].
I have enabled interrupts as below
[size=2]CPSIE ifa, #18
and configured [size=2]Interrupt Security ([/size][/size][size=2][size=2]ICDISR), [size=2][/size][/size][/size][size=2][size=2][size=2][size=2]Interrupt Edge Trigger Config ([/size]ICDIF),[size=2]Interrupt Priority (ICDIPR)[/size][/size][/size][/size],[size=2]Interrupt Target Processor (ICDIPTR),[size=2]Interrupt Enable (ICDISER),[size=2]Interrupt Priority Mask (ICCPMR),[size=2]Interrupt Binary Point (ICCBPR),[size=2]Interface Control Register (ICCICR),[size=2]Distributor Control Register (ICDDCR)
Am I missing something?
Is something separate need to be done, when using IRQS interrupts?
Thanks
Lokesh

The IC in the Cortex-A9 MPCore is GICv1.
Although the GICv2 specification document notes the differences between v1 and v2.
