Esp32 crashing problem

simogaspa84 · February 6, 2025, 10:33pm

Hi community…
I was updating my libs when i discovered than some of them are not anymore supported.

lib_deps = 
	me-no-dev/AsyncTCP@^1.1.1
	me-no-dev/ESP Async WebServer@^1.2.3

In order to be able to compile i had to use the ltest version

	ESP32Async/AsyncTCP
	ESP32Async/ESPAsyncWebServer

and moreover update my platform to .6.3.2

I was able to compile but now when i try to send data with ssl and wifi with mqtt my system is crashing… I was wondering if some of them had this issue or if you can share the old libs… thanks

You should check your code. Form the messages I can see that you’re at least trying to initialize SPIFFS multiple times!

Also check why the key’s in Prefences not found.

But the root cause of the crash is clearly:

Guru Meditation Error: Core 1 panic’ed (LoadProhibited). Exception was unhandled.

You’re writing to an invalid memory location. There can be multiple reasons:

writing to a location that has not been allocated
writing to a location that has been released before
writing to an array but out of bounds (int arr[3]; arr[5] = 42;)
…

A good way to find out where the crash happens is to use the exception decoder in platformio.ini:

monitor_filters = esp32_exception_decoder

This should give you a hint where to look.

Example:

Guru Meditation Error: Core  1 panic'ed (StoreProhibited). Exception was unhandled.

In this case #0 leads to “setup() at src/main.cpp:8”

Example program of this crash:

#include <Arduino.h>

void setup() {
    Serial.begin(115200);
    Serial.println("Hello World");
 
    int* intPtr;
    *intPtr = 42;
}

void loop() {}

A look at line 7 to 8:

    int* i;
    *i = 42; //<-- here does the crash happen as the memory for the int ist not allocated yet
