Support for vTaskList and vTaskGetRunTimeStats

[trlafleur]

Will these FreeRTOS function be exposed in a future release of the Arduino code build?

vTaskList
vTaskGetRunTimeStats

You could compile the libraries with the needed options yourself:

#1142

I've built the blink example with esp-idf and the appropriate options in sdkconfig (via make menuconfig/Component config/FreeRTOS) and the FreeRTOS options are built. But not entirely clear to me how to merge my build into the arduino-esp32 directories. Do I need to take the entire batch of archives from my project build and just overlay the archives in ../arduino-esp32/tools/sdk/lib? I tried just overlaying the libfreertos.a and get a couple of undefined symbols (_thread_local_start and _thread_local_end); not clear which archive they are in. Are there any other changes or considerations needed?

Follow the directions in issue 1142. You must have your esp-idf repo synched to the same point that arduino-esp32 was last built at (currently f586f5e) or you may have mismatched symbols/functions. It should then just be a matter of copying the libfreertos.a archive to the lib directory. I haven't ever done this for libfreertos.a, but have replaced libesp32 and liblwip.a before.

It would be nice if it just worked without having to rebuild it all when a new release is out...

[lbernstone]

arduino-esp32 is set up for simplicity. If you are micromanaging your tasks, you should probably be using esp-idf or arduino as a component. Please close the issue if this is now working for you.

I finally got this working, there was one little trick that took a while for me to figure out, the arduino-esp32/tools/sdk/include/config/sdkconfig.h needs to be updated with the appropriate defines in the Blink/build/include/sdkconfig.h which is generated by make menuconfig. I did a diff on the files between my esp-idf Blink example build and the arduino-esp32 version and merged the appropriate debug settings:
#define CONFIG_FREERTOS_USE_TRACE_FACILITY 1
#define CONFIG_FREERTOS_USE_STATS_FORMATTING_FUNCTIONS 1
#define CONFIG_FREERTOS_GENERATE_RUN_TIME_STATS 1
#define CONFIG_FREERTOS_RUN_TIME_STATS_USING_ESP_TIMER 1
Only the Blink/build/freertos/libfreertos.a needed to be copied to arduino-esp32/tools/sdk/lib.
vTaskList and vTaskRunTimeStats work now.

As noted in last comment, it can be made to work. It appears that in the "ESP-IDF Release v3.0, release notes" we see that Runtime stats are available in the base code. --> "FreeRTOS Runtime statistics support (configurable via menuconfig)"....

So the work is done, we just need to have a way to enable in the Arduino port with out a re-compile or modification of the base code...

maybe someone can post the libfreertos.a I am unable to create it...

[themindfactory]

Would be awesome for these to be added, more and more people spawning tasks and this info would be nice to have access to.

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

[trlafleur]

is it possible to get these function exposed so one can use them under the Arduino platform...

Thanks

[lbernstone]

Will it make more sense to you if I just say no?
