thank you for the suggestion. i was trying it. Serial.print.ln(loop); got print on serial monitor, the Serial.println(setup); doesn't print on serial monitor

void setup()
{
  // put your setup code here, to run once:
  Serial.begin(115200);
  delay(1000);
  Serial.println("setup()");
}

void loop()
{
  Serial.println("loop()");
  delay( 1000) ;
}

result on serial monitor:

loop()
loop()
......
