ZCU102 AXI Interrupt Handling

[eduardoparra]

Hi,

Im trying to catch an interrupt from an AXI GPIO switch from my board ZCU102. I have created the following design in Vivado:

 

 

The design is validated so now im using Petalinux to boot linux. I have exported the .hdf file and built petalinux but i can't boot linux.It hangs after that:

If i boot petalinux by qemu i manage boot linux, but the interrupt i defined in the design does not appear on the system

I'm beggining with embedded linux so i don't know if i'm missing something.

Any idea??

We don't have any MPSoC Zynq boards yet so I haven't had a chance to play with that part yet (Grrrrrrr). So basically I can't guarantee I'm right, but I got a guess...

It looks like you are booting successfully but your uart console is being disabled. Maybe you could try to ssh into it over a network connection to test this. If this is the case, you could try adding something along the lines of this to your bootargs using petalinux-config:

console=ttyPS0,115200 earlyprintk

I think that should ensure that you get a console over UART after boot. You might need to replace ttyPS0 with whatever node the MPSoC UART driver creates. For zynq this was always either ttyPS0 or ttyPS1.
