VDMA example

Support
1

Hello pynq community,

I am trying to move from axi-dma to axi-vdma, because I am going to develop a custom processing pipeline with a sensor.
I am wondering if there is a loopback example with axi-vdma where we send an image over one channel and we receive it from other channel. I want to be sure that vdma works before adding more complexity to the design.

Kind Regards,
Ricardo

Hi @Ricardo_Tapiador,

The base overlay for the PYNQ-Z1, PYNQ-Z2 and PYNQ-ZU use a VDMA, not in loopback as you are looking for, but these could be a good starting point.
