After reinstalling the portenta board file and restarting the computer, solved the problem.

@milanvarghese No, the battery comes into the play only if there is no power from the solar cell. It's like inverters in our home. They activate only if main power is gone, rest of the time they keep charging. similarly here the direct power will be coming from the solar cell, only if the solar cell can't produce enough voltage battery comes into the loop and starts providing voltage to our circuit.

😀 👍 . solved right?

Thank-you @salmanfaris
It's solved.
Actually, It was my mistake. I didn't add a proper reset for MCU.

It's good.

@salmanfaris Actually I'm not sure what was that Core 0 register dump:
But I parsed the JSON. Refer Here for cJSON example. But while working this one, faced another problem. HTTP response includes the whole headers, status code, and body. JSON parser only work if the whole response in the form of JSON. So, Initially stored all responses into a char buffer and cleaned all headers. By using if(response[i] == '{' ) and some flags.
