I want to use trace macros.
In my FreeRTOSConfig file the maro configUSE_TRACE_FACILITY is = 1.
Then I have the following task:

static void vPeriodicTask( void *pvParameters )
{
    vTaskSetApplicationTaskTag(NULL, (void *)1);
    for( ;; )
    {
        vTaskDelay(5);
        mPORTAToggleBits(BIT_0);
        IFS0bits.CS1IF = 1;
    }
}

but when I try to compile it the following error appear:

Make sure that configUSE_APPLICATION_TASK_TAG =1

confgUSE_TRACE_FACILITY is not required to use the trace macros. It is only for the old trace system. Best to set to 0.

The problem was that the macro ConfigUSE_APPLICATION_TASK_TAG =1
was not in the FreeRTOSConfig file. After add this macro to the file the program compiled without any problem.

Thank you.
