Shared interrupt (IRQ_F2P[15:0]) is level triggered is the issue.

Jump to solution

Hi everyone,

 

I am using zynq Arty-Z7-20 board. Vivado version v2020.2

 

Shared interrupt (IRQ_F2P[15:0]) is the level high trigger.

How do I change it to positive edge in "Petalinux"?

 

Regards

Hello @bfung_2,

I have found the solution. We can change the triggering type in the device tree.

#interrupt-cells = <2>;
interrupts = <0 20 4>; 

The second cell shows the triggering type.

1 = rising edge

2 = falling edge

4 = Active high

8 = Active low.
