TSK_create CCS4 does not work consistently

You haven't provided enough information for any conclusion to be reached.

TSK_Create does not work consistently.. Sometines the task is executed and sometimes it does not.

Is the TSK_create() failing?

Is TSK_create() succeeding but the TSK never executes?

Where's the rest of your code?  Where's the .tcf file contents?

Is the code above from main()?

These questions are just some of the information you need to provide.  You can attach source code with the little paper clip in the compose window.

Hi Rob,

I'm using DSPBIOS 5.41.09.34 for C6748 Device.

TSK_create()  creates task initially.. but when I try to execute the same code again and again it fails to create task.

void main()
{
  TSK_Handle demo_tsk;
   

    // create task
    demo_tsk = TSK_create(LOCAL_upp_demo, NULL, 0);

    if (demo_tsk == NULL)
        LOG_printf(&trace, "TSK_create() failed.\n");
}

// LOCAL_upp_demo is the primary DSP/BIOS TSK function.  It is called
// after main

static int LOCAL_upp_demo()
{
   
        LOG_printf (&trace, "Test Task Creation");
   
    return 0;
}

When I run this code the control goes to LOCAL_upp_demo once when I execute it repeadly the task does not get created and does not goto the task created.

,tcf file is here
