I am trying to read 2 different sensor values and publishing them to an mqtt server from 2 different cores.
It starts off nicely but after some time I get this following error and the core1 reboots. So I am get data from core1 but core0 doesn't work.

CORRUPT HEAP: Bad head at 0x3ffe84cc. Expected 0xabba1234 got 0x3ffffff8
assertion "head != NULL" failed: file "/Users/ficeto/Desktop/ESP32/ESP32/esp-idf-public/components/heap/./multi_heap_poisoning.c", line 199, function: multi_heap_free

Rebooting...

Hi Andreas,

I developed a Gate Door opener via WebInterface.
The Interface looks like that:

If you push the Button the ESPx switches a relais, and if the Door Status changes the Button changes the color.

I use therefore:

• Websocket
• Webserver
  and separate html, js and css files

My code runs fine on the ESP8266 for many years.

I tried to bring this code into the ESP32 with dual core functionality.
But I have to use some parts in the traditional loop() if not the ESP crashes.
Are you interested to discuss this point with me?

Hello Andrea
Thank you so much for your excellent work!

In certain conditions it seems relevant to designate core #0 for an Interrupt Service Routine instead of core #1.

Do you know how to do that?
Kind regards
Aurelien

Hi Andreas, your videos on the LED fade (PWM) and creating tasks and assigning them to a specific cpu core were really great and easy to follow. I am trying to make a temperature controlled forced-air furnace vent. I am using a 12vdc gear motor to open and close the louvers depending on the room temperature. I created a sketch that uses the ledcWrite(channel, duty) function as in your example. I works great. I then moved this code into a task and tried running on CPU 0 and CPU 1, but the motor doesn't turn on. I assume that it should work, I have looked the code over several times over days. Here are the two sketches. If you have a chance, please them over.
Thanks in advance for help with this:

First: Thanks a lot for your effort creating such a huge pool of information about ESP!!!

I used the Multi-Core feature for a main-loop (reading/sending sensor-data) and a LED-Status loop.
The LED-Loop (run on CPU#0) controls all my status LEDs which use JLed-Library and if sending take some time (run on CPU #1), the status leds are not affected.

But the message "Task watchdog got triggered. The following tasks did not reset..." (you also mentioned in your video) is realy annoying.

Do you have a solution, how to prevent such message? Change logLevel or do some other magic?

Thx, in advance
Olli
