standalone mode  ps can not get PL to PS interrupt

testing  zcu106  a53  standalone mode  PL to PS interrupt, base on  xscugic_example.c and modify  soft interrput  to irq0(121U) , an Axi register to triggle the signal to irq0.   Connecting in pl is below:



modified xscugic_example.c is below:

Unfortunately ,  ps can not get the intterrupt .  i have checked the signal is triggled in system_ila_0. 

Is there anything to config?  Any point is helpful , thanks.

Re: standalone mode  ps can not get PL to PS interrupt

Hi linken_mu@163.com ,

Looks like the custom IP interrupt port is not interrupt typed by definition which is connected to PS IP's irq port.

You need to make sure in properties of custom IP interrupt port is of irq type def.



Don’t forget to reply, kudo, and accept as solution.

Re: standalone mode  ps can not get PL to PS interrupt

problem is solved . after setting interrupt's trigger(raising edge), ps get the interrupt. Thanks for attentions.
