CCS/TMDSDSK6416: impossible to compile an assembly language file

Part Number: TMDSDSK6416

Tool/software: Code Composer Studio

good day.
Currently, I have the TMS320C6416 DSP Starter Kit (DSK). A bit old but quite powerful card.
As a complement to this test hardware I am using the book:


Digital Signal Processing and Applications with the TMS320C6713 and TMS320C6416 DSK (second edition)

Recommended to anyone who does not know it. However, some sample assembler programs for the floating point card TMS320C6713. They cannot be compiled for the TMS320C6416 card. Of course, I already modified the libraries according to my card, even so I receive an error that says "impossible to create linker file" Below I leave the code that I am trying to execute

specifically it is example 4.14 of the previously mentioned book (page 201).

Does anyone have an idea why the linker file cannot be created?

    I have never seen that diagnostic.  The image you attempted to attach is not visible.  What tool or utility emits that diagnostic?

    Thanks and regards,

    sorry for my late answer. I attach the code in assembler. I am running Conde Composer 3.8 on windows XP Home edition

    //FIRcirc.c C program calling ASM function using circular buffer

    #include "DSK6713_AIC23.h" //codec-DSK support file
    Uint32 fs=DSK6713_AIC23_FREQ_8KHZ; //set sampling rate

    #define DSK6713_AIC23_INPUT_MIC 0x0015
    #define DSK6713_AIC23_INPUT_LINE 0x0011
    Uint16 inputsource=DSK6713_AIC23_INPUT_LINE; // select input source
    #include "bp1750.cof" //BP at 1750 Hz coeff file
    int yn = 0; //init filter's output
    interrupt void c_int11() //ISR
    {
    short sample_data;
    sample_data = (input_sample()); //newest input sample data
    yn = fircircfunc(sample_data,h,N); //ASM func passing to A4,B4,A6

    output_sample((short)(yn>>15));
    return;    		 //filter's output
    //return to calling function

    }
    void main()
    {
    comm_intr(); //init DSK, codec, McBSP

    while(1);
    }    		 //infinite loop


    ASM:

    ;FIRcircfunc.asm ASM function called from C using circular addressing
    ;A4=newest sample, B4=coefficient address, A6=filter order

    delays .space 256 ;init 256-byte buffer with 0's
    last_addr .int last_addr-1 ;point to bottom of delays buffer

    I'm confused.  Does the problem occur when building or when running?  

    If the problem occurs when building a C file, then for that C file, please follow the directions in the article How to Submit a Compiler Test Case.

    If the problem occurs when building an assembly file, the process is similar.  Except you cannot preprocess an assembly file.  It appears this assembly code does not include any other files, so preprocessing is not required.

    Thanks and regards,

    -George

    the problem occurs during compilation. Thank you, I will verify the treath as soon as possible
