Hello!

I remember downloading the reference design from wiki, but the link does not appear available anymore. This one looks the same:

https://www.intel.com/content/www/us/en/programmable/support/support-resources/software/download/refdesigns/ip/interface/dnl-pciexpress-hp-avalonmm.html

You could find the recent version of "avalon-dma" and "avalon-drv" drivers here:

git@github.com:a-gordeev/linux.git avalon-dma-engine

git@github.com:a-gordeev/avalon-drv-tool.git master

Here is some explanation:

avalon-dma - DMA engine driver that provides generic interface to the Avalon DMA engine;

avalon-drv - sample driver on top of a custom A10 design (see Alaric board link below) that uses avalon-dma engine;

avalon-drv-tool - user-level sample utility that uses avalon-drv interface to execute DMAs;

I used Arria® 10 SoC FMC IDK for development:

It would be interesting if you give it a go.

Thanks!
