@qrios

In this case 32Mb of already reserved memory is plenty enough, so I decided against making changes to that. But if you need more ram for your accelerator, doing what qrios suggests is probably the easiest way to reserve chunk of memory, just add mem=512M to bootargs section of the device tree and you have divided memory in two - one half for Linux one half for your accelerator/app.

Repository linked above includes Python library and a test app that interfaces with AXI DMA via UIO driver.

While the design I used as an example is a simple loopback, MM2S is connected to S2MM via a FIFO buffer, the same approach can be used for connecting more advanced accelerators, just replace the FIFO with your IP block.
