What board in Arduino IDE should I select for esp32-wromm-32U?

Other Hardware 3rd Party Boards

I tried both "esp32 dev module" and "ESP32-WROOM-DA Module" but none of them seem to be working, when I run a test sketch I get this error message, can anyone please help?

Hi @syr_maria. What exactly were you attempting to accomplish when you encountered this error message?

I ask because this error message indicates you are clicking the "Start Debugging" button in Arduino IDE, but you don't mention anywhere in your post that you were actually attempting to use the Arduino IDE 2.x integrated sketch debugger.

I am just getting started to learn, and I wanted to run this test code
/*********

Complete project details at Getting Started with VS Code and PlatformIO IDE for ESP32 and ESP8266 | Random Nerd Tutorials
*********/

#include <Arduino.h>

#define LED 2

void setup() {
// put your setup code here, to run once:
Serial.begin(115200);
pinMode(LED, OUTPUT);
}

void loop() {
// put your main code here, to run repeatedly:
digitalWrite(LED, HIGH);
Serial.println("LED is on");
delay(1000);
digitalWrite(LED, LOW);
Serial.println("LED is off");
delay(1000);
}
,its from this tutorial Getting Started with ESP8266 NodeMCU Development Board| Random Nerd Tutorials

so I uploaded it, and when I upload it I get this error mesaage

So this is why I was trying to debug.
Any tips or help, please? :frowning:

Esp32 dev module should be fine.
Non of your tutorials linked are for you, first one is not for arduino ide and second one is not for esp32.
Try this:

Hold down the boot button while uploading

for 1 second or so and release (once 'Uploading'... begins)
