Error while running wifi code

[techievex]

Hi all,

I have been trying to running wifi code in ESP32 module which is placed on a breakout board but there seems to be a guru mediation error, I have already tried to give it external power supply to eliminate the brownout message. But the guru mediation error is still there. Here is the detailed error message and the decoded message too.

Error Message:
Guru Meditation Error: Core 0 panic'ed (Interrupt wdt timeout on CPU0)

Hope so, somebody can help me out here.!

Can you post your code? Just an error dump is not that useful if we don't know what your code tried to do.
