arduino-esp32littlefs-plugin
Please use the universal combined plugin for all FS instead of this one.
Arduino ESP32 LittleFS filesystem uploader
- Arduino plugin, which packs sketch data folder into LittleFS filesystem image and uploads the image to ESP32 flash memory
- Everything is kept identified as SPIFFS for compatibility with your previous code like drop-in replacement
- Same partition scheme and "data" folder is used
- You can use either LITTLEFS or SPIFFS but not both simultaneously on given Arduino project
- The LITTLEFS library for arduino-esp32 core is here
- A PR to embed it to esp32 core is made, too. See the PR status here
Installation
- Make sure you use one of the supported versions of Arduino IDE and have ESP32 core installed.
- Download the tool archive from here
- In your Arduino sketchbook directory, create tools directory if it doesn't exist yet.
- Copy the tool into tools directory (the path will look like
<home_dir>/Arduino/tools/ESP32LittleFS/tool/esp32littlefs.jar
).
- You need mklittlefs tool Download the release
- Copy it to /tools folder of esp32 platform where espota and esptool (.py or.exe) tools are located
- Restart Arduino IDE.
On the OS X create the tools directory in ~/Documents/Arduino/ and unpack the files there
Usage
- Open a sketch (or create a new one and save it).
- Go to sketch directory (choose Sketch > Show Sketch Folder).
- Create a directory named
data
and any files you want in the file system there.
- Make sure you have selected a board, port, and closed Serial Monitor.
-
Select Tools > ESP32 LittleFS Data Upload menu item. This should start uploading the files into ESP32 flash file system.
When done, IDE status bar will display LITTLEFS Image Uploaded message. Might take a few minutes for large file system sizes.

Quick building on Win:
- Install Java JDK
- Find the path of javac.exe and jar.exe
- Edit make_win.bat accordingly
- Copy files arduino-core.jar , commons-codec-1.7.jar , pde.jar from your Arduino IDE installation to the folder where is located make_win.bat
- Run make_win.bat
- Find the build jar in /bin directory
