Hi everybody,
I'm an electronics engineering student and I'm studying zynq platform on my own. I started doing some custom peripheral on the PL side of the xc7z020 soc. With axi4 lite memory mapped peripheral I have no problems at all (I have some experience with arm microcontroller so it is the common way to talk with simple peripheral). Now I'm trying to design a custom AXI4-Stream peripheral: as a simple example I'm trying to interface a FFT v8 axi4 ip core to the ps7. Now the problem is that I would like to do such memory buffer streaming and interfacing my axi4 stream peripheral with a DMA, so the arm processor could take data directly from memory.
I instantiate FFT core in XPS, than AXI DMA engine but I thing I miss something connecting all together...
Has anyone already done something like that? Can you please link some example about connecting PL with DMA and DDR memory? or in general connecting axi4 stream with dma in general...
I would like to excuse me but I'm at the very beginning with this kind of platform :)
