HPS-to-FPGA Interrupts

Has anyone here any experience from using HPS-to-FPGA Interrupts? I have custom IP-blocks that should receive interrupt signals from Linux (HPS). I guess that the HPS's GIC cannot send interrupts to ...

Hi,

The GIC interrupt controller is a function of the ARM core and is designed to handle incoming interrupts. If you want to have the FPGA handle interrupts from the HPS, you should connect the HPS interrupt output to an interrupt input on a Nios II. If you can be more specific about your particular interrupt scenario, I may be able to give you more detailed guidance.

Regards,
