Unable to use the whole memory in ESP32 with Arduino

Using Arduino Programming Questions

Hi,

I have a problem in the amout of memory allocated in my esp32

Basically i want use the Whole potentiality of my esp32 in particular the whole memory about 400k. I chosed ESP32 for this reason. I've tried it on the Raspberry PI Pico W and it works well but i want change platform because esp is cheaper.

The problem is that when I'm calling a function that calls other functions it gives me the error "ERROR A stack overflow in task newloop has been detected."

I've investigated the reason and i putted in my program the follow code:

void newloop(void* param) {
//MY CODE
}

void setup() {
// put your setup code here, to run once:
Serial.begin(115200);
xTaskCreateUniversal(newloop,"newloop", 32*1024, NULL, 1, NULL, ARDUINO_RUNNING_CORE);
vTaskDelete(NULL);
}

void loop() {}

But unsucessfully, the error stil appear.

I qant higllight that my code soes not user dynamic allocation and all variables and structures are allocated directly in the stack statically,

What i can do?

How much ram did you allocate for the stack (32*1024 ) and how much do you need ?

Do your large variables need to be on the stack ? (Recursive calls ?) use global ones where you can
