(This is my first thread in this forum please correct me if i postet this thread in the wrong place or violated other rules.) My goal is it to generate random data in HPS and use it in the FPGA and then manipulate the data to send it back to HPS. Just some bits would be enough to understand the mechanism. I am using a thrid party demo-board with the SOC-CV. What i have achieved so far is running Linux an the board and the boot process is working, but i am having a hard time trying to understand how the fpga-hps and hps-fpga bridges work, which i believe i need for the data transmission. I am a bloody beginner with Altera-SOC any examples or hints are highly apprecheated.
