LittleFS : cannot upload

[christianw]

Hello,
I am trying to use littleFS with a web server on ESP32.

It is an ESP32-S3-WROOM from freenove, the dev computer is a linux debian 11, IDE 1.8.13 and 2.1.0

The example provided with the littleFS library works, that's something. In comment of the example there is :

Code: Select all

/* 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 */

I didn't format anything, but the example works. I guess everything is OK
I followed the link to try to install the plugin, the readme.md starts with

Please use the universal combined plugin for all FS instead of this one.

so I followed that second link and followed, I think, the instructions. But the tools menu doesn't match the capture in the tutorial: https://raw.githubusercontent.com/lorol ... r/tool.png

On my IDE, I have the capture below. By the way, no mention of LittleFS in the Partition Scheme submenu.



I read elsewhere :

If missing, you need to copy mkfatfs[.exe] to /tools folder of esp32 platform where espota and esptool (.py or.exe) tools are located

How should I understand this? I have

mklittelfs in ~/.arduino15/packages/esp32/tools/mklittlefs/3.0.0-gnu12-dc7f933/
esptool.py in ~/.arduino15/packages/esp32/tools/esptool_py/4.5.1/
espota.py in ~/.arduino15/packages/esp32/hardware/esp32/2.0.8/tools

I put everything in the ~/.arduino15/packages/esp32/hardware/esp32/2.0.8/tools directory

but without effect

What else can I do?

The plugin will not work in Arduino IDE 2.0 for the moment.
In 1.8, place the jar file in ~/Arduino/tools/ESP32FS/tool. I'm not sure exactly where that folder is in Windows, but you can see where your sketchbook location is in Arduino preferences.
Close Arduino and reopen, then you should have "ESP32 Sketch Data Upload" in the tools menu.
I have the helper programs in that same tools folder.
Note well, file systems should only be used for user data (mp3, gcode, etc). Read only "files" should be embedded in your firmware as C-strings. Configuration data, including certificates, should be stored in NVS (aka Preferences).

That's fine ! Thanks a lot... I'll be back for further questions
