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
