Hello,
I use FreeRTOS source 7.1.0 with Frescale IDE codewarrior special Edition, so i dont have any operating system for this version. But i has opensource 7.1.0 that i add to my project. It s works correctly.
My device is MC9S12XEQ512
I have two timer one of them is used to generate tickcount for RTOS and the second is used  to calculate  CPU charge using vTaskGetRunTimeStats.
I set in FreeRtosConfig.h :
#define configGENERATE_RUN_TIME_STATS 1
#define portCONFIGURE_TIMER_FOR_RUN_TIME_STATS() Timer_GetRunTime_OnInterrupt()
#define portGET_RUN_TIME_COUNTER_VALUE () ulHighFrequencyTimerTicks

the Timer_GetRunTime_OnInterrupt is a Interrupt for my second timer :

#pragma CODE_SEG __NEAR_SEG NON_BANKED
ISR(Timer_GetRunTime_Interrupt)
{
  PITTF = 0x04U;                       /* Reset interrupt request flag */
  Timer_GetRunTime_OnInterrupt();      /* Invoke user event */
}

#pragma CODE_SEG Timer_GetRunTime_CODE

the event “Timer_GetRunTime_OnInterrupt()” is defined into events.c as follow :

void Timer_GetRunTime_OnInterrupt(void)
{
  /* Write your code here … */
  ulHighFrequencyTimerTicks++;
  }

when i compile the “task. c” i have some errors

Thank you for your help

Hello,
could you post the kind of error messages you see, and which version of CodeWarrior you are using?

thanks!

Hello,
FYI, I’m using the port described in
http://mcuoneclipse.wordpress.com/2012/02/11/back-to-classic-freertos-for-freescale-s12x/
with CodeWarrior for MCU 5.1 (classic, not eclipse). I have performance counter enabled, and it works for me just fine.

C2450: Expected   IDENT char cont double enum float int long short sigend struct union unsigend void volatile
and some error
the cursor is set in the line itnt task.c

Hello,
as the error is for the macro portGET_RUN_TIME_COUNTER_VALUE(), which is using ulHighFrequencyTimerTicks:
can you make sure that task.c includes the header file which contains ulHighFrequencyTimerTicks?

I think that you are missing to include the declaration for ulHighFrequencyTimerTicks.

Hello,
I has include the header file which contains ulHighFrequencyTimerTicks, it s name is “Events.h” and ulHighFrequencyTimerTicks is decalared as extern.

Hello,
well, then it is hard to tell what the problem could be. Maybe attach/provide a link to your project and I can have a look.

Hello,
Finaly i have find the problem, it s came frome my macro i have written :
#define portCONFIGURE_TIMER_FOR_RUN_TIME_STATS Timer_GetRunTime_OnInterrupt()
#define portGET_RUN_TIME_COUNTER_VALUE  ulHighFrequencyTimerTicks
and not
#define portCONFIGURE_TIMER_FOR_RUN_TIME_STATS() Timer_GetRunTime_OnInterrupt()
#define portGET_RUN_TIME_COUNTER_VALUE () ulHighFrequencyTimerTicks

i checked the function it works corectly but i have a problem in my timing when i add the second counter my tasks are not accurate it is normal?
