Running Optimization Flags for NiosV app and bsp

I am trying to condense my code to resolve a "can't place all RAM cells in design" compilation error and am new to the niosv processor. Is there a way to run optimization flags on both niosV applicat...

    Hi,

    This is from the NiosV Embedded Processor Design Handbook on page 81.

    Hello,

    For more information, I looked at the sw/app/CMakeLists.txt and realized it does include "include(../bsp/toolchain.cmake)." Correct me if I am wrong, but this makes me believe that adding optimization on the bsp also optimizes the app code?

    I have tried adding additional flags according to the embedded design handbook.

    https://www.intel.com/content/www/us/en/docs/programmable/683689/current/reducing-the-code-footprint.html

    niosv-bsp -c <path to settings.bsp> -qpf=<path to .qpf> --cmd="set_setting hal.make.cflags_optimization {-Os}" --cmd="set_setting hal.enable_reduced_device_drivers" --cmd="set_setting hal.enable_lightweght_device_driver_api"

    (Note: it would not let me enable the small c library...)

    My application code is still rather large and I am curious if there is any additional flags or options for niosv

    Apologies for the thread hijack but I've been trying to respond to Fathulnaim on my own thread https://community.intel.com/t5/Nios-V-II-Embedded-Design-Suite/Debugger-wont-connect-to-NIOS-II-hello-world-on-Cyclone-GX/m-p/1544031#M52319 and I just can't. I'm so frustrated by the forum software and my problem isn't resolved. Please investigate why I can't post and please remove this post as I really, really don't like to hijack another user's thread.
