ESP32 Keeps rebooting after code uploaded

[bhavish030]

Hello all,

I've seen the previous similar issues, but i don't know yet if there has been a fix to this since i can't really understand the explanations and i a newbie to ESP32. Very sorry for that but can anyone explain to me clearly, if possible, how to fix my ESP32.
These are the errors appearing on my serial monitor:

Actually i have 4 ESP32 and each one of them used to work perfectly until last week 3 of them started to behave abnormally for no reasons.
If anybody can help me out to fix this, that would really save my life>.
Thank you

I suspect if the ESP32 keeps rebooting you're having brownout issues This happens sometimes when your code starts up WiFi etc and the power demand is too high for the supply.

Try this; At the top of your sketch put this

Code: Select all

#include "soc/soc.h"
#include "soc/rtc

then in setup() add

Code: Select all

WRITE_PERI_REG(RTC_CNTL_BROWN_OUT_REG, 0);

If this is your problem, the brownout detector will be disabled and the ESP32 won't reboot but you should look at your supply for a proper fix. However, I disable brownout detection all the time. Hope this helps.

Steve.

Sorry, Ive just scrolled down your error and seen that its probably NOT brownout. Teach me to jump in with both feet!

There were breaking changes to the way the EEPROM library is handled recently. Judging by the NVS error and your claim it was working fine a little while ago, that's my guess.

I think you can either pull the very latest Arduino-ESP32 from GitHub or roll back to whatever you had when it was working fine.

To anyone still having this problem:
I solved it simply by downgrading the esp32 board package by espressif in the arduino board manager.
if your version is 2.0.11, select 2.0.10 and install that instead. it will replace the newer version automatically.
Apparently 2.0.11 breaks a bunch of libraries including the Heltec libraries, if you have one of those boards

Thanks for Downgrade ESP32 to 2.0.10 from Board/Library management in Ardiuno IDE its stop resetting Problem i have Solved problem by this Thanks
