I'm trying to code NUCLEO-H755ZI-Q in Arduino IDE but it doesn't work.

[mscyb12345]

I'm trying to code the NUCLEO-H755ZI-Q in the Arduino IDE and it uploads but won't run.

I have the USB connected to USBPWR and the jumper connected to STLINK.

The code is written like this:

void setup() {

 Serial.begin(115200);

 while (!Serial);

 Serial.println("NUCLEO-H755ZI-Q: Hello from M7 core!");

}



void loop() {

 Serial.println("Looping...");

 delay(1000);

}

The code was uploaded but nothing was output on the serial monitor.

Please let me know why and how to fix it.

Thank you.

I don't see nucleo-H755zi  in the list of officially supported boards.

Welcome to the forum.

Please see How to write your question to maximize your chances to find a solution; in particular How to insert source code.

The Arduino IDE should allow you to use the debugger - so have you used the debugger to see what's happening?
