output file can not be generated in ccs

This is the screen shot of the project explorer.The code  is about  pwm generation of 1khz and it is done with f28335 and peripheral explorer kit.

Hi arun,

your build failed, hence you have no .out file.

<Linking>
error #10008-D: cannot find file "IQmath_fpu32.lib"
error #10008-D: cannot find file "rts2800_fpu32_fast_supplement.lib"

The linker doesn't find the above librarys and can't resolve all symbols. You have to adapt the linker library search path.

Best regards,
Christian

Thank you christian for your reply.I did as you said but error still persists and i have included a screenshot of paths included in the linker.

error #10234-D: unresolved symbols remain

As there are still unresolved symbols, it seems you're indeed using the header files of some libraries, but you still don't include those libraries into your build.
Just including the library header files only tells the compiler that there are function/symbols somewhere, but it does not provide these functions/symbols to the linker. First you have to identify the libraries for those unresolved symbols, than you either need to add the appropriate precompiled library files to the linker settings, or you have to add the source code of the libraries to your project.

Arun,

Double-check that you have all the source files that were in the original example project. I believe you are missing DSP2833x_GlobalVariableDefs.c. Make sure to add that source file to your project. Also as Christian mentioned earlier, double-check that all the libraries (and their paths) are correctly set up in your test project similar to what is in the example. It looks like you already have the necessary libraries though, so I think adding the DSP2833x_GlobalVariableDefs.c should do it.

Hi

Thank you Christian and Aarti for your suggestions,i got it right.It was due to unnecessary linking of file paths.

hi arun,

I have the same problem with generate .out file.

I' am  working with the same device f28335, and  i want to generate PWM too.

Can i have your project Example_2833_xCpuTimer, please ?

i can give you my email if you want.

cheers Fabio.
