I am pretty new at this but I found two 'problems' with the v9 code.

In the FreeRTOS.h file there are two instances of #ifndef configMAX_PRIORITIES. The second instance is not actually verifying the value.

Just before line 1906 of tasks.c I had to add a line #if ( configGENERATERUNTIME_STATS == 1 ) with an #endif following line 1906 in order to compile.

Hello Mike,

Which port are you running?

It could help for us to see the options you have enabled in your FreeRTOSConfig.h file.

I have been running v9 since RC1 and haven't run into what you've mentioned - but this could be due to what features you have enabled/disabled.

Regards, John W.

Thank you for taking the time to provide this feedback.

The second instance of configMAX_PRIORITIES has been changed to:

#if configMAX_PRIORITIES < 1

I think your second issue is probably a misconfiguration, and could have been corrected by simply removing the definition of portCONFIGURETIMERFORRUNTIME_STATS from your FreeRTOSConfig.h file - but as per John W's post, without seeing your FreeRTOSConfig.h file I can't be sure.

Thank you both.

I have changed the FreeRTOS.h file to have.

#ifndef configMAX_PRIORITIES
 #error Missing definition:  configMAX_PRIORITIES must be defined in FreeRTOSConfig.h.  See the Configuration section of the FreeRTOS API documentation for details.
#elif configMAX_PRIORITIES < 1
#error configMAX_PRIORITIES must be defined to be greater than or equal to 1.
#endif

My other problem was indeed an improper FreeRTOSConfig.h file. I had copied it over from the CORTEXKinetisK60TowerIAR demo project:

#define configGENERATE_RUN_TIME_STATS	0
#define portCONFIGURE_TIMER_FOR_RUN_TIME_STATS() vMainConfigureTimerForRunTimeStats()
#define portGET_RUN_TIME_COUNTER_VALUE() ulMainGetRunTimeCounterValue()

but I hadn't defined the two functions in code.
