hi,

After connecting 32K crystal to the defined pins of esp32. I didn't see any warning of clock changing to internal oscillator .
Now when the board went into deep sleep and is not able to wake up. When I reset I recieve flash read err,1000, Hence I made attached changes but still the issue exists.

Thanks,
Karim

Have you tried increasing the 'Extra delay in wake stub' value?

Yes, Tried it was 2000 I have changed it to 5000.

Changing the values sometimes I get external oscillator not detected using150KHz internal oscillator
