Hi,

Can someone please give some help on how to actually use the interrupt. I have a FIFO setup connected the light weight avalon master. The interrupt from the FIFO is connected to the HPS.

But how do I set up the device tree.

I read up somewhere to generate the device tree file from the sopcinfo file. I tried doing this but I got the following response.

"Master and slave interfaces for the Transparent bridge in fifo_0 of type altera_avalon_fifo have different types."

Any thoughts?
