Interrupt number in dts

[xiaodongplayer]

Hi all,

I am trying to add an axi-timer to generate an interrupt from PL to PS. I found this guid of xilinx here : http://www.xilinx.com/support/answers/62363.html

My question is how to or where to find the three numbers assigned to interrupt like in this example of xilinx: "interrupts = <0 59 4>;"?

I am using ZYBO and Vivado 2015.4.

Thanks,

Hi,

for assign one interrupt use this formula (subtract 32 to the value of the interrupt)

Interrupt in linux "61":

IRQ_F2P[15:0] == [91:84],[68:61] ==> 61 - 32 = 29

Value on DTS:

 interrupts = <0 29 4>;

Once started linux can check assignment with this command:

cat /proc/interrupts

From previous example:
