Sample use of the Run Time Statistics function on S32K144

fengjuntian — Mon, 28 Jun 2021 02:00:00 GMT

hello,

I created a FreeRTOS project and used vTaskGetRuntimeStats () to get CPU usage.

But the program kept running portFORCE_INLINE static void vPortRaiseBASEPRI( void )

Please provide a sample program, thank you!

Hi,

have you enabled the statistics in the freertos component?

Regards,

Lukas

Thank you. I've solved the overflow problem.

I configured both options

#define portCONFIGURE_TIMER_FOR_RUN_TIME_STATS() /* nothing */ /* default: use Tick counter as runtime counter */

#define portGET_RUN_TIME_COUNTER_VALUE() xTaskGetTickCount() /* default: use Tick counter as runtime counter */

My new question is, how do I calculate the CPU usage statistics for every five minutes?
