I want to discard unused sections using -gc-sections and -ldo, but I can't find where to do that in the environment. The version of STM32cubeIDE I'm working with is 1.12.1, Any help would be greatly appreciated.

Hello @jose Navarrete Pineda​ 

First let me thank you for posting.

The option you are asking for is already activated by default in CubeIDE. Under "Properties / C/C++ Build / MCU GCC Linker / General" you will find a check box associated to the "-l--enable-non-contiguous-regions" option.

 

I just want to add that in case you need to add any GCC Linker command, which is not already embedded in the tool, go under "Properties / C/C++ Build / MCU GCC Linker / Miscellaneous" and add the command in the "Other flags" section.

 

I hope my response is helpful for you. If that's the case don't hesitate to mark it as best answer.

KR,

Semer.
