Code optimization in MCUxpresso

topspin — Wed, 14 Jun 2023 14:35:49 GMT

Hello,

I have made a project from scratch in MCUxpresso IDE.

I want to try different optimization level as explained here Compiler Optimization - NXP Community

But I am not able to find how to do it.

I go to Project--> Properties and then I have this pop up but I cannot find the proper setting tab

Can you tell me how to do it?

Hi @topspin ,

it would be better if you could post a full screenshot instead just of a part of the dialog. You probably miss the 'go left' buttons for the settings.

The settings look like this:

As an other way, you could use the Quickstart panel to access the settings:

Hi @ErichStyger

The panel is as I posted. I am missing several tabs. How can I add the "tool settings" ?

here a full screenshot

Maybe you have configured it for a different/incompatible tool chain?

Can you share your .project and .cproject file?

Hi @ErichStyger

. project

.cproject

That does not look like a MCUXpresso IDE project, as it lacks the

<nature>com.nxp.mcuxpresso.core.datamodels.sdkNature</nature>

in the .project.

Did you really create an SDK project? See attached files for a valid project.

No I did not create the SDK project. Can't I use optimization as well?

The thing is: if you are not creating a project with the correct tool chain, nature and plugins referenced, you won't be able to see the toolchain (optimization, etc) options.

How do you think the IDE will know about the compiler optimizations, if the project is not configured correctly for the compiler/toolchain you want to use?

So: you have to create a proper/correct project if you want to use all this.

if you create just a 'project without any toolchain and no SDK information' you won't be able to use this all.

If you don't want to use the SDK, but just use a 'bare toolchain' project, then I recommend you install and use the GNU MCU Eclipse plugins.

Can I install the MCU eclipse plugin in MCUxpresso? is there a reference guide?

I don't understand what you are up to.

You can install the MCUXpesso IDE, which comes with the toolchain, plugins and SDK support preinstalled.

Or, you can create a bare-metal project with you own makefile and a command line build.

Yes, see for example https://eclipse-embed-cdt.github.io/

But why are you not using what the MCUXpresso IDE provides with the SDK?
