sine wave TMS320C5416 assembly language program "output section" warnings

abhishek srivastava

i am getting another warnings while compiling for sine wave TMS320C5416 processor in assembly language. i use to get these in many programs.what they say and how to remove them?

these are the warnings i got:
<Linking>
>> warning: creating output section COSINE without SECTIONS specification
>> warning: creating output section STACK without SECTIONS specification
>> warning: creating output section CODE without SECTIONS specification
>> warning: entry point symbol _c_int00 undefined

Build Complete,
0 Errors, 4 Warnings, 0 Remarks.

and here's the code for sine wave i tried:

FREQ1000 .set 1486
FREQ1750 .set 2600
FREQ2000 .set 2972
FREQ3000 .set 4458

what's the problem now?

The linker wants you to add the sections COSINE, etc to the linker command file to make sure they go into valid memory.

so what should i do to get rid of these warnings?

in some examples (sine wave), sine.dat file is used?from where that file occurred?is it some standard file that is to be used or it is generated from somewhere?how to get such .dat file for any other example where graph might require?

please explain the process to find this file/generate and what does it mean?

thank you

I have no idea what the origin of sine.dat is, or how it's expected to be used in the program.

To get rid of the warnings, modify the linker command file so that it places those sections, like so:

SECTIONS
{
    COSINE PAGE 1
    STACK PAGE 1
    CODE PAGE 0
}

thanks for reply

i am still getting one more warning

<Linking>
>> warning: entry point symbol _c_int00 undefined

how to resolve this? i have not used _c_int00 any where in program.

I think sine.dat is used to see the output in form of graph.something required for file I/O.do we to do so to see any output in graph?

so how you would suggest me to see the output of sinewave/any waveform program?any other way ?

please tell
