Hello
My esp 32 resets sometimes and it is not periodic. Sometimes it runs for 20hours without problem and sometimes it is just 20mins or so.
I included the decoded backtrace of CPU1 and serial terminal data. Everytime it has happened, backtrace was same.
Can anyone give some kind of light to this.
Thank you
