Dear All,
I am fairly experienced in the old ESP32 chips and now I am starting to use the newer ESP32-S3 chips, and in my first project an ESP32-S3-MINI-1. Read all the documentation and datasheet, but I can't get it to start.
I am using The Arduino framework in Visual Studio Code + Platformio.
Here is my platformio.ini:

Code: Select all

[env:esp32-s3-devkitc-1]
platform = espressif32 @ 5.3.0
board = esp32-s3-devkitc-1

framework = arduino

monitor_speed = 115200
monitor_port = COM3

monitor_filters =
    colorize
    esp32_exception_decoder

upload_port = COM3
upload_speed = 921600

This is the code I am trying:

Code: Select all

#include <Arduino.h>

#define LED_PIN GPIO_NUM_5

void setup() {
  pinMode(LED_PIN, OUTPUT);
  digitalWrite(LED_PIN, LOW);

  Serial.begin(115200);
  Serial.println("Start blinky");
}

void loop() {
  Serial.println("LED ON");
  digitalWrite(LED_PIN, LOW);
  delay(200);

  Serial.println("LED OFF");
  digitalWrite(LED_PIN, HIGH);
  delay(200);
}

It compiles and uploads just fine, but when starting to run I get the following in the serial terminal:

Code: Select all

ESP-ROM:esp32s3-20210327
Build:Mar 27 2021
rst:0x1 (POWERON),boot:0x28 (SPI_FAST_FLASH_BOOT)
SPIWP:0xee
mode:DIO, clock div:1
load:0x3fce3808,len:0x44c
load:0x403c9700,len:0xbec
load:0x403cc700,len:0x2920
entry 0x403c98d8

Any idea what's going wrong?

I had the same problem. What worked for me was to delete .platformio folder in your users folder. The next time you open platformIO it will reinstall everything and then it worked properly.
