configuring axi_gpio interrupt

Hi everyone,

using the example codes in SDK, I've managed to handle swtiches & leds connected to axi_gpio in an interrupt routine.

I'd like now to configure the interrupt in such way:
1)only 1 or 2 bit trigger the interrupt (now every bit in the gpio channel trigger it);

2)only the edge low to high triggers the interrupt (now every change status triggers the interrupt)

how can I do these configurations? where can I find information?

thanks in advance!

In looking at DS744, it doesn't appear that the current AXI_GPIO can do what you want. You can independently enable each of the two possible channels, but not the individual bits inside those channels. I also don't see that there is any control over the trigger mechanism.

I suggest you open a support case with Xilinx to see if they have a modified version of this core internally that accomplishes this.

thanks a lot for the answer.
I will use the axi_intc controller, it allows all the configurations I need

I post here my question so I don'T have to open a new thread.
I'm trying to configure the axi_intc controller but in XPS the fields "C_KIND_OF_INTR", "C_KIND_OF_EDGE" AND "C_KIND_OF_LEVEL" are fixed at 0xffffffff and they aren't editable.
why happens that?
