----------------------------- Remove above -----------------------------

Hardware:

Board: esp32wroom32 - Arduino ESP32 Dev Module, yes.
Core Installation/update date: latest, fresh install
IDE name: Arduino IDE 1.8.5, fresh install
Flash Frequency: 40Mhz?
Upload Speed: 115200

Description:

I don't know how this happened but I got a problem with 2 esp32 units -one with the below indicated issue, plus, another one I've just tried after having problems with the first ESP32 unit-.
I can compile any example or my own sketches but, once the sketch is loaded, it doesn't work and, through the serial monitor I can only get same message, which makes me think if both units have same problem (same day?) because of soft or hardware reasons (?) as "core 0" is continuously mentioned:

Just in case:
I have re-installed Arduino IDE and also charged the last latest ESP32 library version (https://github.com/espressif/arduino-esp32).
I have pushed the "Boot" & "En" buttons for long times... doesn't matter: the sketch is compiled, and uploaded but... the ESP32 shows always same issue/message.
...............................................................................................................................................
I'm totally newbie with Arduino and programming (0 knowledge!) but I have been able to connect some sensors to both ESP32 units and connect them to a couple of IoT platforms and get those sensor values on the account I opened. However, since yesterday both units show same problem.

Sketch:

It doesn´t matter the sketch: the unit simply seems to reboot all time... (!)

As mentioned at the very top of the issue report, please run EspExceptionDecoder to determine what is throwing the exception in your code. If an example sketch like WiFiClient throws this same error, then wipe your device by running python esptool.py erase_flash and try again.

Thanks, Ibernstone. I'll try that this evening!

Is this in combination with the DeepSleep-Mode? I had issues with that in combination with the Serial.println function.

Nope, @thetotalwimmer , in my case it was after installing/adding "SmartConfig" a few days ago, 'though I am not saying that there is a "cause-effect" relationship.

these two commands help me for erase flash. -p with COM4 where ESP32 is connected is required from windows device manager view.
pip install pyserial
python esptool.py -p COM4 erase_flash

after erase of flash following is error. Please advise How it can be fixed to use this eSP32 module. below is continuous error and I was not able to fix it.

First of all, it is not a good practice to high-jack an issue with something unrelated. You should open a new issue if you cannot find an issue that addresses flash read err, 1000

I had the exact same issue today with a cheap Chinese ESP32 Wrover board.

Problem with flash read err, 1000 was related to a power supply issue.

After supplying from a 2.1A USB power supply the error went away and the ESP32 works as expected.
Supplying from USB port of my PC and the error comes back.

Try a big capacitor on GND and +5V pin of the ESP32 modules or look for a powered USB hub that gives enough power on USB.

mmashraf commented Aug 2, 2019

thank for response please suggest capacitor value. Even I connect new power supply with good reading but I have to upload program which is also not happening

@beegee-tokyo

Try 470uF or larger.

What could help as well is to try a different USB cable.

For me 2 out of 5 USB cable have problems to supply the ESP32 when connected to the PC.

If you are on Windows, check the settings for the USB ports. Mine was set to "Allow to shutdown USB device for power saving". Disabling that helped as well.

Same thing on me! I was programmed ESP32-CAM in my office with my laptop and I left it while it's properly working. After that, I came home and I started to connect it again. Only one thing happened as extraordinary, I've connected directly +5v and board had been warmed a lot, and then I realized it and I plugged it to 3.3V. After that, I started to get this script on the serial port. Did anyone fix it yet?

this happened using an i2c sensor and not initializing correctly mysensor.begin();
i copied some code and removed a check for a bad connection.. if (mysensor.begin() == false ){
and by doing so I removed the initialization of the sensor on the bus...

The error:

load:0x40080400,len:6364
entry 0x400806b8
Brownout detector was triggered

Is caused by poor power connections on the board.
After spending weeks thinking it was a software issue, I took a tester and started to measure power consumption and voltages on the ESP32-CAM. The ESP32 was plugged in an cheap breadboard with several wires.
The board consumption was around 110-200 mA and I was powering it with 5V on the breadboard with wires to the 5V pin and GND. I did not power the ESP board directly, but the breadboard, with some other pin wire cables to do the connections.
I discover than on the power supply wire I had 5.02V, but on the VCC5V pin of the ESP32 I had 4.42V !!!! Impossible but true.
And while I pushed or moved the ESP board on the breadboard, or moved or pushed power cables on the breadboard, the voltage values changed randomly from 4.02 to 5.02V. Then by chance I got the 5.02V on the ESP32 board, and I re-flashed the firmware, very carefully to not move the contacts, and as of sudden all worked fine without any brownout error.
After some minutes I moved by mistake a power cable, and the board dropped on the table, creating false contacts again, and again I had fluctuating voltages and brownout error at boot, until I was able again to have a more or less correct contact.

LESSON LEARNT: NEVER USE breadboard to power such boards, and use a specific shield with power supply plug, or solder the wires directly.

I had the same error but it was my code. I had a for without variable initialization

for (int i; i < 8 ; i++) {
str_id[i] = Msg[i];
}

I initialized i=0 and the problem was solved. Maybe this is not the case, but It can be helpful for some one.

for (int i=0; i < 8 ; i++) {
str_id[i] = Msg[i];
}

It works for a teensy but when I migrated the code to ESP32 It crashes
