DE0-Nano-SoC: How HPS(ARM) recognizes f2h_irq0 or f2h_irq1 interrupts from FPGA

I designed a block in Verilog. When data processing is finished, this FPGA block sends an interrupt signal to HPS using one of dedicated interrupt line: f2h_irq0 or f2h_irq1. The question is how HP...

Hi Nachodizz990,

Finnally, On the ARM console, I successfully got received IRQ from counter implemented in Verilog. I assigned counter's overflow flag (source of IRQ) to PIO. In addtition, I assigned this flag to LED. In C, I have a while loop printing PIO IRQ value on the console. When on the console, displayed PIO's IRQ value changes from 0x0 to 0x1, on the board I see that LED is ON.

Thank you very much for your support:)
