Default optimization level for a project created by MXCube.

[Pevy.Andy]

I have a project that is created by Cube for the Keil compiler.

The MCU is the STM32L486VG family.

The default optimization level in that project is set to -O3 but I'd like it to be -O0.

I cannot see where the default value gets set. I am assuming that it is in Cube as it reverts to O3 whenever I regenerate the project.

Can anybody enlighten me please ??.

Thanks,

Andy

Hello @Community member​ ,

A similar issue is already reported in https://community.st.com/s/question/0D50X00009bLP0eSAG/adc-init-bug-with-optimization-o1-stm32l4.

It is tracked internally and Optimization will be settable from STM32CubeMX GUI soon. Stay tuned, waiting for STM32CubeMX versions.

Hi @kurta999​ ,

Thanks for your feedback.

As said by Amel , for this optimization , it is expected to be settable via STM32CubeMX in 5.1.0 version.

Where can I find this setting?
I'm using CubeMX Version 6.11.0.

Every time I generate code for CubeIDE, the optimization setting is reset to -Ofast, even in the Debug profile.
