Arduino-esp32: boot crash: /Users/ficeto/Desktop/ESP32/ESP32/esp-idf-public/components/freertos/queue.c:621 (xQueueTakeMutexRecursive)- assert failed!

Created on 25 Jul 2019 · 18Comments · Source: espressif/arduino-esp32

I am new to Esp32 dev, but I have succesffully developed for ESP8266 already.
So I am trying to get ESp32 AI Thinker module with OV2640 camera module working.

The sample sketches I tried are working, and I have started to adapt the sample code into my own existing project.

It compiles fine but crashed with the following output:

Rebooting...
A sample Sketch (https://github.com/yoursunny/esp32cam/blob/795e3a615f5076a1c5acdcd20f31d14bdf2bfe59/examples/WifiCam/WifiCam.ino) I used works fine with the same settings:ets Jun 8 2016 00:22:57

Well I found out it was caused by static object of a helper class I made to control eeprom.
The constructor called "EEPROM.begin" before setup() was called.

I found this using EspExceptionDecoder found here:
https://github.com/me-no-dev/EspExceptionDecoder

Very usefull tool

To close, got the next ASSERT!

These assrtes are really annoying.
I have to say that WIFI has not been started at this point when my UDP Server starts, is that the problem?

Any chance to disable configASSERT() ?

Hello,
I have the same crashing allert in my code. My code has to do with wifi setup configuration via BLE . I managed to run it properly one time, but from the time i reset my esp32, this problem started to occur. I tried to download the EspExceptionDecoder but i cannot see the ESP Exception Decoder menu item. Can you guide me on how to install it properly?
Also, any further possible solutions to my problem are well acceptable :)

ChristosPalisidis on 25 Jul 2019

My code is actually that of Mr Bernd Giesecke ,only upgrating from ArduinoJson 5 to 6 :
https://bitbucket.org/beegee1962/esp32_wifi_ble_esp32/src/master/src/main.cpp

ChristosPalisidis on 25 Jul 2019

Well it appears that this xQueueGenericReceive assert happens for various reasons.

At first it was because a constructor of a static object was calling "EEPROM.begin" before setup(9 was executed.

I am not sure yet if it happens because I am starting network services before WIFI is connected.
This and all my other code worked perfectly fine on ESP8266 before.

Regarding EspExceptionDecoder, I just following the Installation instructions and copied the extracted release to "/Arduino/tools/", I am on Windows. Then just restarted Arduino IDE.

I really would like to disable those ASSERTS

alorbach on 25 Jul 2019

@alorbach you can not disable the ASSERTS, they are there for a reason! You are attempting to access/use functionality prior to it being configured/initialized. There global constructors will be invoked before app_main (IDF side) is invoked so you should only use the constructors for storing of values in the class instance and save actual init/config until a begin() like method is called from setup().

atanisoft on 25 Jul 2019

@atanisoft : I understand, but in my case setup() is finished and I have moved the UDP Server Start to top of my loop() function.

Still I get the ASSERT

/Users/ficeto/Desktop/ESP32/ESP32/esp-idf-public/components/freertos/queue.c:1442 (xQueueGenericReceive)- assert failed! abort() was called at PC 0x4008bc69 on core 1
See above...

However WIFI has not been started at this point, is this the problem?

alorbach on 25 Jul 2019

If you are attempting to use WiFi (UDP would!) then yes it is a problem in YOUR code. Since you haven't shared your code it is impossible to assist in tracking down what went wrong.

atanisoft on 25 Jul 2019

Well thats all I want to know.
I am using many classes and includes, so it isn't so easy to share my code.

I have used this code on ESP8266 without any problems, so I will look into changing the code that all network services are started after WIFI.Begin Call is made.

alorbach on 25 Jul 2019

@ChristosPalisidis you need JAVA Runtime installed for ESPExceptiondecoder

alorbach on 26 Jul 2019

i have the same rebooting prob on esp32 cam got from aliexp... i need help... thanks in advance the example code which i used to run(worked before) now it causes SW_CPU_RESRET and reboot.
exception decoder gives

@VigneshTheLearner your issue appears to be unrelated to this issue. Your issue appears to be related to a corrupt NVS, it failed to read the expected amount of data from NVS. You likely can fix the issue by erasing the flash and reuploading the sketch. If this does not fix your issue please open a new issue to track your crash.

works after earsing the flash and reupload thank u bro @atanisoft

@SalmaG98 This is also an unrelated issue. Please do not hijack the thread. Post your backtrace in a new issue if you want help.
