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
