Linker error TMS320F2808 Experimenter kit sprc207.

Other Parts Discussed in Thread: TMS320F2808

Hi,

I have downloaded the program sprc207 for Implementation of sensored Indirect FOC of Induction motor for TMS320F2808. It was written for ccsv3.3.

But I'm using ccs Version: 5.5.0.00077. On building aci3_3.pjt using the 'Import legacy 3.3 projects' option i get the following linker error as given below.

Hi Barnabas

How did you import the project? Did you use the legacy import wizard? (project->import legacy ccsv3.3 proejct)

Did you check whether the current control suite has an equivalent example you can start with?

Best Regards,

Lisa

Hi Lisa,

Yes, I used the legacy import wizard. And Current control suite does not have an example for 'SENSORED INDIRECT FOC OF INDUCTION MOTOR. I used the file sprc207 from ti.com

Hi,

I have attached the screenshot of the console window.

Hi Ramkumar,

Please post a new query on a fresh post!

Anyways, I guess this error has occured due to improper inclusion of IQMath lib files.

Please go through the following doc for more info on the same: 2781.IQmath_Quickstart.pdf

Gautam

Hi Ramkumar,

I agree with Gautam, that it is likely you need to add/include a library.

See this wiki as well

Hi Lisa,

I included the latest IQmath.lib from control suite. Still I get the same errors as given in the screenshot. Please help.

Ramkumar.

Hi Ramkumar

- how did you include the library

I would not mix old and new projects. My best advice .... open a new workspace and start directly with a project imported from the resource explorer/control suite. Help-Welcome to CCS opens the resource explorer.

Lisa

Hi Lisa,

The application which I am working on is 'SENSORED INDIRECT FOC OF 3PHASE INDUCTION MOTOR, in the kit 'TMS320F2808 Experimenter's Kit'. This project is not present in 'CONTROL SUITE'. It's present in sprc207. So I am unable to import the file from CONTROL SUITE. Please help.

Ramkumar

Hi Rakumar,

can you please be more specific? I downloaded the sprc207 examples, which are for ccs 3.3. However I was able to import an build at least two of them in ccs v5.5. I did not see any examples named as per your post.

Best Regards,

Lisa

I assume you are referring to the project aci3_3_280x_CCS3x.pjt. I was able to reproduce the linker errors after importing this project into CCSv5. The reason for the errors is that the libraries F280xDRV_ml.L28 and iqDMC_ml.L28 are not getting automatically picked up in the build. If you take a look at the Project Explorer view, you will see these 2 libraries linked to the project. However, because f their extensions (.L28 rather than .lib) they are not automatically picked up for the link (you can verify this by looking closely at the linker step in the CCS build console - notice that IQmath.lib and rts2800_ml.lib are there but not the 2 .L28 libs).

To fix this, right click on the project, go to Properties->Linker->File Search Path. In the --library option field, add the paths to both of these libraries (see my screenshot below). This should fix those earlier linker errors. Hope this helps.

Hi Aarti,

Thank you for the help. The Linker error is now resolved. The program now runs without any errors.

Thanks again.
