If i am reading this correctly?
PYNQ only uses the first line of IRQ in the Python IRQ source? So no matter latest nor older PYNQ revision the IRQ also need the AXI Interrupt block to handle more than ‘ONE’ IRQ source?
Or more specific:
PYNQ Python IRQ set to IRQ_F2P [61] or DTSI interrupts = <0 29 4>?
Just want to learn more about the backend.
Thank you
ENJOY~
Hi,
That describes exactly the behavior I observed, thanks for the clarification.

Partially correct. PYNQ only uses index 0 or IRQ. But, in 3.0.1 (perhaps since 2.7, I don’t recall exactly) we support a single interrupt connected to IRQ. I’ve tested this changed myself.
This is detailed here Interrupt — Python productivity for Zynq (Pynq)
PYNQ Python IRQ set to IRQ_F2P [61] or DTSI interrupts = <0 29 4>?
I think this is generated automatically by petalinux based on a simple project. https://github.com/Xilinx/PYNQ/tree/master/boards/Pynq-Z2/petalinux_bsp/hardware_project
