With the "ESP32 Arduino Release v3.1.1 based on ESP-IDF v5.3.2" you can no longer use the Core 1!

Hello ESP community,
First of all, thank you for the great work.

Since the update "ESP32 Arduino Release v3.1.1 based on ESP-IDF v5.3.2" you can no longer activate Core 1 with the function "xTaskCreatePinnedToCore"!
It is probably deactivated under "FreeRTOS->Run FreeRTOS only on first core".
But unfortunately that doesn't work in an Arduino environment! Please help.

Many thanks

I can not confirm this. Tasks are running on both cores (check with printRunningTasks(Serial);)

Tasks: 7, Runtime: 67s, Period: 2032000us

this is what it looks like for me with "printRunningTasks(Serial)"

[jhbirkou]

when I run the following code:

void taskCore1(void *pvParameters) {
while (true) {
// Code für Core 1
Serial.println("Running on Core 1");
vTaskDelay(1000 / portTICK_PERIOD_MS); // Pause für 1 Sekunde
}
}

void setup() {
Serial.begin(115200);

// Erstelle die Aufgabe auf Core 1
xTaskCreatePinnedToCore(
taskCore1, // Funktion, die die Aufgabe ausführt
"TaskCore1", // Name der Aufgabe
2048, // Stack-Größe
NULL, // Parameter
1, // Priorität
NULL, // Handle
1 // Core, auf dem die Aufgabe ausgeführt wird
);

printRunningTasks(Serial);

}

void loop() {
// Code für Core 0
Serial.println("Running on Core 0");

delay(1000); // Pause für 1 Sekunde
}

then I get the following error message:

some more information, this is about:
ESP32-C6 (N8)
Arduino IDE 2.3.4

Thanks for your help :)

C6 is single core :)

[jhbirkou]

oops. Thanks for the tip :)
I was able to pass tasks to Core 1 with the old version (V3.0.7), I think the library corrected that itself ;)

Thanks for the quick help :)
