I am currently working on adding the PYNQ software on a custom board. So far I have the Ubuntu 18.04 image from Pynq Z2 working on my board. I did a basic overlay(the example from the readthedocs) and it worked without any problem. My actual design consists of a dma. When i am trying to see what’s in the dma object in python, i get the following error “ValueError: Could not find UIO device for interrupt pin for IRQ number 0”. I looked into the source code where this error is thrown and found out that I don’t have any uio device in /dev. When I look in /sys/devices/soc0/amba_pl/410… i can find “generic-uio” there.
I also checked on the pynq z2 board in /dev and I can see 2 uio devices.
For that I have two questions: what are the two uio devices on pynq z2 and why on my board i don’t see any?
Thank you in advance!
