Hi Vivek,

I believe that what you are seeing is what comes after the logs that you want to see. The Serial port doesn't wait for you to connect, if nothing is connected to the port, it will just get forgotten.

So if you keep the serial connection connected and reset the board by pressing the reset button, you should be able to see the logs you want to see.

Another thing that you can see, is the time code in front of the logs. These are the up-time of the chip at the moment of the log. In the example you can see that it all happens in the first 10 seconds, but in your case you are already past 20 minutes.

I hope I was able to help you!

Best regards,
