Just toggle an option on and off, save config and build.
thank you Hans,

make clean
make menuconfig
toggle an option
saved
make menconfig
toggle an option
saved
make all

same error

best wishes

seems few core/task utilies are missing in the freertos or gone private

I don't know what gives here.

I'm using the arduino IDE because I like it's simplicity, but have the SDK installed somewhere, too.

I'll try playing around with it during the weekend and see if I can get the task stats running.


Cheers

Remember that the source of FreeRTOS is in the ESP-IDF.

vTaskGetRunTimeStats is a macro ...

Not sure if this applies to the ESP IDF.

There's no MPU_vTaskDelay in libfreertos.a, but vTaskDelay is there.

Also, the code for vTaskGetRunTimeStats can be found in tasks.c

hi guys

thank you

yes found the double as macro defined too
but we have it in tasks.c as function too

https://github.com/espressif/esp-idf/bl ... ks.c#L3989

btw we have
tasks.c and task.h

Currently I am helpless

best wishes

edit:
Where is the sorting what may go into the freertos lib and what is not
we have no OBJS ( .o ) file in the build too
so where is this outsorted in the makefile? project_makefile?

ok..
https://github.com/espressif/esp-idf/bl ... ks.c#L3987

Code: Select all


#if ( ( configGENERATE_RUN_TIME_STATS == 1 ) && ( configUSE_STATS_FORMATTING_FUNCTIONS > 0 ) )

so where we set this config in the menuconfig ?
https://github.com/espressif/esp-idf/bl ... sk.h#L1360

we have to set manual?

Code: Select all

#define configGENERATE_RUN_TIME_STATS 1
mhm..

C:/eMbeddedHome2017/CLK_erzeuger/hello_world/main/hello_world_main.c:23:0: warning: "configGENERATE_RUN_TIME_STATS" redefined

further test:

// #define configGENERATE_RUN_TIME_STATS 1
#ifdef configGENERATE_RUN_TIME_STATS
#undef configGENERATE_RUN_TIME_STATS 
#define configGENERATE_RUN_TIME_STATS 1
#endif
helps not
edit :
https://github.com/espressif/esp-idf/bl ... TOS.h#L620

Code: Select all


#ifndef configGENERATE_RUN_TIME_STATS
	#define configGENERATE_RUN_TIME_STATS 1 // test rudi .orig is 0
#endif


error

Code: Select all


#if ( configGENERATE_RUN_TIME_STATS == 1 )

	#ifndef portCONFIGURE_TIMER_FOR_RUN_TIME_STATS
		#error If configGENERATE_RUN_TIME_STATS is defined then portCONFIGURE_TIMER_FOR_RUN_TIME_STATS must also be defined.  portCONFIGURE_TIMER_FOR_RUN_TIME_STATS should call a port layer function to setup a peripheral timer/counter that can then be used as the run time counter time base.

		#endif /* portALT_GET_RUN_TIME_COUNTER_VALUE */
	#endif /* portGET_RUN_TIME_COUNTER_VALUE */

https://github.com/espressif/esp-idf/bl ... TOS.h#L638

Code: Select all

#ifndef portCONFIGURE_TIMER_FOR_RUN_TIME_STATS
	#define PortCONFIGURE_TIMER_FOR_RUN_TIME_STATS()
#endif

next step?

RTFM
http://www.freertos.org/rtos-run-time-stats.html

we need to create 2 macros
portCONFIGURE_TIMER_FOR_RUN_TIME_STATS()
portGET_RUN_TIME_COUNTER_VALUE()



best wishes

edit:
seems to be a weekend work
here are examples from other cpu's
http://www.freertos.org/Free-RTOS-For-N ... C17xx.html
http://www.freertos.org/portLM3Sxxxx_Eclipse.html

so perhabs
the best will be we create for this an ESP32 example too?

Curious if anyone else has any updates on getting CPU utilization working in % using Arduino?

I'd like to print each core's CPU utilization in "xx%" in a serial terminal window...

thanks
