$build.attributes without SECTIONS

Hi Marcio,

What version of code generation tools are you using?

Can you update to the latest one?

Please see:

Hello Mariana,

I don't know wat are the versions that i was using but i did the lasted updates.

So, i compiled and the problem with the tasks apparently disappeared.

But it's still showing this warnings:

"C:\syscProj\sys460\sys460bioscfg.cmd", line 262: warning: symbol
   "CLK_F_gethtime" from file
   "C:/CCStudio_v3.3/bios_5_41_03_17/packages/ti/bios/lib/biosDM420.a64P<clk_ge
   thtime.o64P>" being redefined
warning: creating output section ".TSK1$stk" without a SECTIONS specification

Could this warning give me problems in the future?

Thanks for your help.

Hi Mariana,

My actual code generation tools is v7.0.2.

I found what was happening, about the tsk warning.

I configure a second .cmd file to helps on memory allocation. So I had include this second .cmd file to my project and into put the command for include my normal .cmd file. The mistake was at the include command that was with a wrong way. I correct e rebuild. Now it’s ok.

But I’m still having problems.

I have two tasks with the same priority, task0 and task1.

The task 0 is the first to be executed because their order. And when the “FVID_control” is called is executed the task1, at the for(;;) loop after task_yield() it’s doesn’t return to the task 0.

//--------------------------------------------------------------------------------------------
void task1 (){

    asm(" NOP");

    for(;;){
        TSK_yield();
        asm(" NOP");
    }
}

//--------------------------------------------------------------------------------------------
Void task0 (){
    if (fn_configVpss()){
            return; //Error
    }

    for(;;){
    }
}

//--------------------------------------------------------------------------------------------
void fn_configVpss(){

        unsigned int i;

PSP_VPBEChannelParams beinitParams;
PSP_VPFEChannelParams feinitParams;
GIO_Attrs gioAttrs = GIO_ATTRS;

  // Create ccdc channel
    feinitParams.id = PSP_VPFE_CCDC; //Ccdc YCbCr and RAW
    feinitParams.params = (PSP_VPFECcdcConfigParams*)&ccdcParams;
    ccdcHandle = FVID_create("/VPFE0",IOM_INOUT,NULL,&feinitParams,&gioAttrs);
  if ( NULL == ccdcHandle) {
    asm(" NOP");
    return(-1);
  }

  // Configure the TVP5146 video decoder
    if( FVID_control( ccdcHandle, VPFE_ExtVD_BASE + PSP_VPSS_EXT_VIDEO_DECODER_CONFIG,
                    &tvp5146Params) != IOM_COMPLETED ) {
        return(-1);
    } else {
        for ( i=0; i < NO_OF_BUFFERS; i++ ) {
            if ( IOM_COMPLETED == FVID_alloc( ccdcHandle, &ccdcAllocFB[i] ) ) {
                if ( IOM_COMPLETED != FVID_queue(ccdcHandle, ccdcAllocFB[i] ) ) {
                    return(-1);
                }
            }
        }
    }

    // Create video channel
    beinitParams.id = PSP_VPBE_VIDEO_0;
    beinitParams.params = (PSP_VPBEOsdConfigParams*)&vid0Params;
    vid0Handle = FVID_create( "/VPBE0", IOM_INOUT,NULL, &beinitParams,
                            &gioAttrs );
    if ( NULL == vid0Handle ) {
        return(-1);
    } else {
        for ( i=0; i<NO_OF_BUFFERS; i++ )  {
            if ( IOM_COMPLETED == FVID_alloc( vid0Handle, &vidAllocFB[i] ) ) {
                if ( IOM_COMPLETED != FVID_queue( vid0Handle, vidAllocFB[i]) ) {
                    return(-1);
                }
            }
        }
    }

    // Create venc channel
    beinitParams.id = PSP_VPBE_VENC;
    beinitParams.params = (PSP_VPBEVencConfigParams *)&vencParams;
    vencHandle = FVID_create( "/VPBE0", IOM_INOUT, NULL, &beinitParams,
                            &gioAttrs);
    if ( NULL == vencHandle ) {
        return(-1);
    }

    if (FVID_alloc( ccdcHandle, &FBAddr )!=IOM_COMPLETED){
        return(-1);
    }

    return(0);//Ok sem erros
}

Here is the execution graph.

Thanks.

Hi Mariana,

I'm suspecting about the code generation tools v7.0.2 is causing this problem, because, up to my early sftw that was working well is breaking at the same point.

Is it possible?
