LittleFS Error with XIAO ESP32S3 ?

Other Hardware 3rd Party Boards

Hello,

I have created a program that works with an Arduino Nano ESP32 and an ESP8266. Now I have a new XIAO ESP32S3 and LittfeFS does not work. I use Serial and D2, D3, D4 and D6 for leds.

IDE is Arduino IDE 2.3.4 with Espressif ESP32 Core Package 3.1.1
Board Setting are all default.
What can I do?

I got an error of LittleFS on ESP32-S3

I noticed this in the Example code

/* You only need to format LittleFS the first time you run a
   test or else use the LITTLEFS plugin to create a partition
   https://github.com/lorol/arduino-esp32littlefs-plugin

   If you test two partitions, you need to use a custom
   partition.csv file, see in the sketch folder */

//#define TWOPART

and

void setup() {
  Serial.begin(115200);

#ifdef TWOPART
  if (!LittleFS.begin(FORMAT_LITTLEFS_IF_FAILED, "/lfs2", 5, "part2")) {
    Serial.println("part2 Mount Failed");
    return;
  }

Hi,

I have solved it in the meantime as follows. It was definitely the more complicated way. :sweat_smile:

The solution is, randomnerdtutorials - arduino-ide-2-install-esp32-littlefs

you have to use the plugin
C:\Users\...\.arduinoIDE\pluginsarduino-littlefs-upload-1.5.3.vsix

in Sketch folder > data > filename.txt
This is not the sketchbook ordner. This is in the sketch folder from your sketch.

In the IDE

[Ctrl] + [Shift] + [P]
called 'Upload Little FS to Pico/ESP8266/ESP32'

This will organize the flash for LittleFS. This is a one-time process. Since my XIAO was new, this had to be done later. From now on I can create and write any file name I want in the sketch. Ist alles okay.

Or the shorter way from srnet. :wink: :+1:

Many Thanks.

If I remember a long time ago, I think I did and had to do the same thing with the Arduino Nano ESP32 and ESP8266. It was too long ago. That's why I've certainly forgotten about it.
:thinking:
Thanks.
