I have a friend using the same board on his Win 11 laptop. He doesn't have to do the two button press to upload. I have to and then press Rst button for the display/code to start. We are working on a GPS display using Sparkfun GPS Breakout board XA1110 with Qwiic ports. I had to add some of the Sparkfun GPS code to our GPS code for the T4-S3 to 'see' the GPS.

You can set up a 'New Sketch' and put it where you want!

I have a to do the two button press and release each time I want to upload new code. I read your Setup text and you were able to upload without having to press buttons. You were using IDE 2.1.1? I usually have to press the Reset button to activate the new code and see the Serial Monitor output.

BTW, is there a way to have a separate window open for the Serial Monitor, like in version 1.8.19??

Thanks for your input.

//words preceded by "//"" are comments and are not executed
//Set the Arduino Tools menu to "USB CDC on boot "enabled'"
bool ticktock;  //declare ticktock as a boolean flag

void setup() {           //runs once on start up
  Serial.begin(115200);  //open the serial port for USB cable
  delay(500);
}

void loop() {            //runs in circles!
  ticktock = !ticktock;  //every pass through reverse the flag
  if (ticktock) {        //test current value of the ticktock flag
    Serial.println("tick");
  } else {  //prints one or the other to the USB port
    Serial.println("tock");
  }
  delay(1000);  //wait for a second and run again!
}
