Guru Meditation Error: Core 0 panic'ed (abort)

[JLospinoso]

Hello,

My ESP32 stopped working; I've tried several of the example scripts. All of them yield the following errors:

Hi @JLospinoso ,
Can you erase all flash and try it again please? If the crash persists,please let me know,thanks.

[JLospinoso]

@xcguang Ok thanks, I'll try. I'm using a Sparkfun ESP32 Thing, any ideas on the easiest way to flash it?

[xcguang]

You can try

python /esp-idf/components/esptool_py/esptool/esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 115200 --before default_reset --after hard_reset erase_flash

Hi! I got the exact same error. This solution worked for me.
Thanks @xcguang ! :)

[JLospinoso]

I can confirm that this worked for me as well. Any intuition about what might have happened?

[masadnawaz]

It did not worked for me..can you please help me..??

[xcguang]

@masadnawaz Please try v0.10.0.0,the master branch maybe crash because of libat_core.a

[masadnawaz]

is it because of some problem in the latest github version..??
I am not able to find v0.10.0.0,
can you suggest me some other solution..?
Thanks..

[xcguang]

@masadnawaz
You can run this instruction to clone it

git clone -b v0.10.0.0 --recursive https://github.com/espressif/esp32-at.git

[masadnawaz]

remote: Repository not found.
fatal: repository 'https://github.com/espressif/esp32/' not found

[xcguang]

It is https://github.com/espressif/esp32-at.git,not https://github.com/espressif/esp32/.

[masadnawaz]

with the older version, I m not able to even make the bin files, it start giving errors..
the same newer version is running perfectly on my team mate ESP32 IDF..we have match the menuconfig settings as well, but still i am getting the same error..
Thanks for your suggestions BTW..

I have this error also, on initializing the NVS in my app:

assertion "state == EntryState::WRITTEN || state == EntryState::EMPTY" failed: file "C:/msys32/home/user/esp
/esp-idf/components/nvs_flash/src/nvs_page.cpp", line 316, function: esp_err_t nvs::Page::eraseEntryAndSpan(size_t)
abort() was called at PC 0x400dbc73 on core 0

This error is recurrent. Each day (today is the 3rd time) it happens after using the part for (development) for several hours. If I let it "cool" it starts working again, but not for a long. The next day it works again for quite some time. I don't need to use any special tool to make it working again, just let it cool.

The app doesn't use the radio much.

As said, this error is on my development board, which I have been using for just 6 weeks. In the application I have made sure that the NVS isn't written unnecessarily, so it can't be because of an excessive number of writes. Debug cycles are frequent, but also not that frequent as the debug cycle is close to a minute, and frequently much longer, say 50x per day.

So this worries me! This seems to be a temperature effect, and we'll be using the chip at a relatively high temperature (80 degrees). But for now it is at 18 degrees :) Celsius that is.
