Hello, I am trying to perform an FPGA TO HPS and vice versa communication using the following method. (This platform designer design isn't made by me, took it from the cornell website).
So what i...

Regular ContributorHi,
There is DMA for FPGA and DMA for HPS, which one are you referring to?

New ContributorHello, both. I am trying to use the DMA to send data from HPS to FPGA, and receive the data back from FPGA to HPS. [But the wires that we are sending data and receiving data with to be exported to the FPGA Verilog top level].
Basically i have an monochromatic image in my c code on my hps ( in form of a 2d array), i want to send the data from HPS to FPGA using dma, then on the fpga i want to do some processing on them ( apply on them a digital image filter), and then send the pixels of the image back to FPGA using DMA .
Also i have a question, the c code we put on linux is stored on the sd card inserted into the fpga ( the one linux is intalled on?) or on the sdram?
