Basic Infos

  • This issue complies with the issue POLICY doc.
  • I have read the documentation at readthedocs and the issue is not addressed there.
  • I have tested that the issue is present in current master branch (aka latest git).
  • I have searched the issue tracker for a similar issue.
  • If there is a stack dump, I have decoded it.
  • I have filled out all fields below.

Platform

  • Hardware: ESP-12 (D-Duino V3)
  • Core Version: Commit 559a286
  • Development Env: Arduino IDE
  • Operating System: MacOS

Settings in IDE

  • Module: Generic ESP8266 Module
  • Flash Mode: qio
  • Flash Size: 4MB (2M SPIFFS)
  • lwip Variant: v2 Lower Memory
  • Reset Method: ck
  • Flash Frequency: 80Mhz
  • CPU Frequency: 80Mhz
  • Upload Using: SERIAL
  • Upload Speed: 115200

Problem Description

Running any program leads to the ESP8266 crashing, even the simple blink example or blink without delay. There the led will light once, twice or never and the ESP either gets a hardware watchdog reset or a software watchdog reset

MCVE Sketch

LED_BUILTIN is in this case 2.

int ledState = LOW;

unsigned long previousMillis = 0;
const long interval = 1000;

void setup() {
  Serial.begin(115200);
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop()
{
  Serial.println(millis());
  unsigned long currentMillis = millis();
  if (currentMillis - previousMillis >= interval)
  {
    previousMillis = currentMillis;
    if (ledState == LOW)
    {
      ledState = HIGH;  // Note that this switches the LED *off*
    }
    else
    {
      ledState = LOW;  // Note that this switches the LED *on*
    }
    digitalWrite(LED_BUILTIN, ledState);
  }
}

Output of program

Note that I have cut out the output of the print function, so this issue does not get too long. Also this output shows the output until the ESP stopped working at all.

a) standard flash speed is 40MHz AFAIK
b) did you try with a different board/module to rule out a hw fault?

I had it run for ~1h on my NodeMCU w/o any hickup, allthough with git from 18/08/05

Same here, no problem at all. Looks like a HW problem. Check another board and your power supply, the ESP can be finicky.

Unfortunately I don't have another board to test, but I will try to change the flash speed to 40MHz and see if that makes any difference. I mean I can use one of my other ESP boards to test, but those are not the same ESP-12F, those are other ones.

This issue system is for software issues for the Arduino-ESP8266 framework in this repository. Your problem is not that. Changing code here is not going to fix your problem. If your esp can't run the blink sketch then you most likely have power or other hardware related problems.

That's what I am thinking too now, but there cannot be any power problem. I've checked that. So probably the ESP is defective and I will exchange it for a new one.

I've inspected the board a little more and I could make out a solder link between the 3.3V line and the RX connection of the ESP. After removing that the same behaviour as before persisted, but if I don't use any serial communication the ESP does not reset so often anymore, so it seems that the UART of the ESP might be destroyed causing it to reset, when it is being used. Weirdly enough I can still upload code.
