Hello all, I just wanted to ask a few quick questions.

1. Is there a barebones VDMA example out there? All the ones I see use the base overlay with HDMI, but I want to just process an image and write it back out to memory, no screen required. I did stumble across a video on youtube that did this, but he wasn’t using the pynq.lib.video.dma module, just the addresses, so it was a bit opaque.

I have read these two examples, both with HDMI:

> <https://github.com/Xilinx/PYNQ/blob/master/boards/Pynq-Z1/base/notebooks/video/hdmi_introduction.ipynb>

Here is a screenshot of my block diagram, I just want to read the image, resize it, and write it back:

1. My IP has an interrupt line on it, and I’m not sure why or what to do with it. Should I connect it to the peripheral reset on the processor reset block?
