Hello world,I'm trying to right into the HPS RAM the button position of my atlas-soc / de0-nano-soc. Using Qsys (which I'm slowly discovering), I tried to map the buttons to the RAM bus, the issue is in the address bank of the memory bus. I run Linux in the HPS with the "mem=800M" parameter, so I want to write the buttons position after the 800M firsts bytes. Any idea ?
Hi back,I've tried to continue, my design is now the one attached but it is still not complete. my goal:Get the button position of the De0-Nano-SoC and put the data into HPS RAM, in the last 200MB. my questions:How to define the address in RAM where to write the buttons position? Where to connect control_port_slave of my dma controller IP? Thanks ! Léo :france:
