ESP32 Forum

Hi All!
Here is the scenario:
I am using ESp32 wroom 32E with platformio and arduino framework.
In my code the most of the time the CPU is in deep sleep state.
When the wake up is triggered , it executes a customized wakeup stub that i wrote and that works perfectly. All the code and the variables used within the wakeup stub are placed in the RTC fast memory using "RTC_IRAM_ATTR".
When the processor is awake i would like to reuse all the function used in the wakeup stub but i get 'panic - illegal instruction crash.
The reason is that Arduino loop runs on core 1 and core 1 has no access to RTC fast memory but only through PRO cpu (core 0).
Is there a way to use a stub function also in the main loop?
Thanks to all for your help

Please let me know if my question is stupid or too difficult or not so interesting or out of theme. So i can improve my contribution to this forum. My goal is always to find and share my solutions. Thank you.

Well, to point out the obvious, you could start a task on core 0 to interface with your RTC_FAST stuff?

Thank you ESP- sprite-. I found a work around without using the rtc functions from arduino loop. If you want to post an example here , of a function to make the rtc functions available to core one , all the other users can benefit of this .It Is something that i have not found during my extended searches.
Many thanks
Guido
