Converting an external project in a mcuxpresso project

[tomato]

Hi all,

I am a student and I have a begginer level coding experience. I have a C project that I would like to import and compile with MCUxpresso.

In order to do this I created a new C project in the IDE selecting the target device

Then I imported all the folder of the existing project in this brand new project created in MCUxpresso.

At the end I am getting these two errors

make[1]: *** [makefile:47: projectname.axf] Error 1
make: *** [makefile:38: all] Error 2
"make -r -j8 all" terminated with exit code 2. Build might be incomplete.

Can you help me?

I would recommend another approach.

Take a simple example (like Blinky) from the MCUXpresso SDK for the MCU or board you intend to use, and build and run it first.
Then, take your sources and integrate them into this project.
Alternatively, if you project is IO/peripherals-intensive, choose an appropriate peripheral example.

Hi @frank_m 

ok thanks. I will try it.

Can you tell me if this option could be useful for what I have to do?

[frank_m]

Not exactly what I meant ...

Here an example from my installation:

If necessary, create a SDK for your MCU/board online on the NXP website, download it, and import it into your IDE.
This process is described here as well, I suppose many poster here could assist you with that.

The selection of the proper and most fitting example would be up to you.
Here an example that would fit the "Blinky" description - GPIO LED output.

Pick one that best fits the application you have in mind.
You can add other example projects later, test them separately, and "copy" relevant code to your project.

I did a project for the OM13009 board (LPCXpresso54628) in this way - combining code for an ADC example, an ext. SDRAM example, and a FatFS example into one project.

It would be helpful if you could provide more information and context.

If you 'imported' your folders, you probably have to setup things like include paths to get things compiled, depending on your file structure and way to include files.

Hi @ErichStyger 

You are correct. I had to setup the path for the include folder and this resolved many errors during compiling but not these last two errors reported above ( they should be related to other issues).

what kind of information you need to help me?

Thanks

[ErichStyger]

You need to look at the other messages in the console view, as they have more details about what is not working.

HI @ErichStyger 

thanks for the recommendations. Indeed I was able to fix all the errors and to get the compiled binary file. However the compiled code is not as expected (different dimension and it does not work when loaded in the microcontroller). Can you show me a the proper way to compile an existing project (src,include and build folders and makefile) starting from scratch in mcuxpresso?

thanks

I think you did nothing wrong.

As your application is not working, I think it is now time to start debugging it, step by step, to see what is not working and why.

Good luck!
