Honored ContributorGuys,
I have some doubts. I'm building a system based on another one that I have (DE2_NET - it is in DE2 CD ROM), so I'm trying to understand what the function of each memory element. We find these in the project (one of each): Avalon MM Tristate Bridge Flash Memory EPCS Serial Flash Controller SDRAM The Resect_vector is pointing to Flash Memory and the exception_vector to SDRAM. My doubts: I think that the the .elf is being downloaded to the flash memory, I'm correct? 1. What's the function of each one? 2. Why I need to use EPCS? 3. I only can use flash memory whe I'm using a Avalon MM Tristate Bridge? Ps.: I'm reding some documentations but the differences are still not clear. Thanks
