--- Quote Start --- Maybe I've got it... After you build the new hardware image are you loading it into the board? vendor_hwselect tells the kernel build which hardware to target but it does not put the hardware into your DE2 board. you would need to run nios2-configure-sof or something to get the new image into the board. If you are not doing this, the kernel would think it had more cache than the HW actually has. That could be an issue :). Also, you probably don't need to do this but I always make clean when I'm changing hardware. Hope this helps.[/b] --- Quote End --- Hello halfdome, I am loading the Hardware every time to the board, because I'm testing with volatile memory. I'm not permanently loading the configuration to the FPGA -at least not yet-. However, the cleaning process would be interesting to try. Could you tell me how to do that? And in which step do you do the cleaning? What I do is : Change Cache size in SOPC Builder Regenerate Recompile Make vendor_hwselect Make Make linux image nios2-configure-sof nios2-download -g nios2-terminal also, do you think you could enlist what you do when changing these memories? You mentioned earlier that you 've had no problem with that. please? :D Regrds, FRancisco
