Tried to acquire the core dump as explained here but got message corefile.ESPCoreDumpLoaderError: Core dump version "0x9000" is not supported!

flash was dumped with esptool.py -p /dev/ttyUSB0 read_flash 32768 3072 /tmp/tmp2kvu_ifh

Other Steps to Reproduce

happens on two separate boards, same model, flashed in the same way

I have checked existing issues, online documentation and the Troubleshooting Guide

i have the same kind of issue, WDT gets triggered after a few hours or half a day. I have 5 units ESP322 Touchdown with same software, same problem with all - so its seems iots not hardware. I am using Arduino IDE 1.8.16 , ESP32 Dev Module - espressif system ESP32 Dev version 2.0.5 Arduino runs on Core 1 EVents runs on Core 1

Apart from this issue, everything works fine and Serial.print shows HEAP is stable and not the cause.

Debug prints 18:01:05.764 -> E (54025027) task_wdt: Task watchdog got triggered.

Bump- Similar issue

[apbodrov]

I had exactly the same bootloop, only the address in the backtrace is different. Using another microUSB cable helped

thats my trigger: else if (receivedMessage.indexOf("scan") != -1) { String scanResults = ""; int numNetworks = WiFi.scanNetworks(); Serial.println("Scanning Wi-Fi networks...");

  for (int i = 0; i < numNetworks; i++)
  {
    scanResults += "Network name: " + WiFi.SSID(i) + " | Signal strength: " + String(WiFi.RSSI(i)) + "\n";
  }

  // Send the collected scan results to all clients
  Serial.println(scanResults);
  ws.textAll(scanResults);
}

Anyone found the cause of this yet ?
