Excessive resource usage

[Zanon.Luciano]

Hi, I am attaching a simple .ioc configuration file with which I generated a new project using stm32 cubeide which when compiled generates a footprint of about 12kB.

Frankly, it seems excessive to me, to the point of making this platform unusable for projects with limited memory resources.

This problem has escalated in the latest versions of stm32 Cubeide.

Is there a way to have greater control over the resources used?

You are using the build configuration Debug, which requires additional memory.

You can easily reduce this memory requirement below 5KB if you set the build configuration to Release and also set C/C++ Build > Settings > Optimization to Optimize for size.

Good luck!

Thanks for your quick reply, I did some tests and found that the change from "Debug" to "Release" does not involve any reduction of the footprint.

Changing the compiler optimization to -Os results in a footprint reduction from 10K to just under 5k.
