I am trying to implement simple PL to PS interrupt using the IRQ_F2P line on the Zynq. I have an AXI Lite component that exports a pin with single pin interface as interrupt. I can watch it go high in an ILA for a single clock cycle when I want the interrupt to run.
On the PS I have the following code:
#define INTC_DEVICE_ID XPAR_SCUGIC_0_DEVICE_ID
////#define XPS_FPGA0_INT_ID 61U from xparameters.h
#define INTC_DEVICE_INT_ID XPS_FPGA0_INT_ID
Status = XScuGic_Connect(&InterruptController, INTC_DEVICE_INT_ID,
(Xil_ExceptionHandler)DeviceDriverHandler,
(void *)&InterruptController);
// If I simulate the interrupt without pulling the interrupt pin high it seems to work
Status = XScuGic_SoftwareIntr(&InterruptController,
INTC_DEVICE_INT_ID,
XSCUGIC_SPI_CPU0_MASK);
But it doesn't work with the real interrupt. This is supposed to be easy, is there something I didn't do?
I can show all of the code, it is basically the example from he ScuGic example in the SDK.
Thanks
