ESP32 Forum

Hi.

I have created a simple test project using the Arduino platform on VSCode for the ESP32-S3-N16R8 Board-USBC module.
After compiling and uploading the project to the board, the ESP32-S3 is unable to start properly and keeps resetting continuously.
But, I tested the same ESP32-S3 module with Arduino IDE 2.3.3, and it worked well.”
Maybe something wrong with PIO configuration and tools?
I would appreciate your advice on how to resolve this issue.

Below is the serial output:
ESP-ROM:esp32s3-20210327

Here is the main.cpp file:
#include <Arduino.h>

void setup() {
Serial.begin(115200);
delay(2000);
Serial.println(“Setup()”);
}

void loop() {
Serial.println(“loop”);
}

And the platformio.ini configuration:
[env:esp32-s3-devkitc-1-n16r8v]
platform = espressif32
board = esp32-s3-devkitc-1-n16r8v
framework = arduino
build_flags =
-DCORE_DEBUG_LEVEL=1
-Wl,-Map,output.map

Attached are the following files:
(a) sdkconfig from C:\Users\aaa.platformio\packages\framework-arduinoespressif32\tools\sdk\esp32s3
(b) esp32-s3-devkitc-1-n16r8v.json from C:\Users\ACEN.platformio\platforms\espressif32\boards
I cannot attach the files. If necessary to find the cause of the problem, I will upload the content.”

Thank you for your assistance.

Best regards,

You have not included your json file for that board, but the symptoms sound like it is not compiling with OPI memory support. Make sure your module is a esp32-s3-wroom-2, and use the following options.
