How to use Arduino ESP8266 filesystem uploader

Arduino plugin which packs sketch data folder into SPIFFS filesystem image, and uploads the image to ESP8266 flash memory.

Installation

• Make sure you use one of the supported versions of Arduino IDE and have ESP8266 core installed.
• Download the tool by click here.
• In your Arduino sketchbook directory, create tools directory if it doesn't exist yet. You can find the location of your sketchbook directory in the Arduino IDE at File > Preferences > Sketchbook location.
• Unpack the tool into tools directory (the path will look like <sketchbook directory>/tools/ESP8266FS/tool/esp8266fs.jar).
• Restart Arduino IDE.

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 > ESP8266 Sketch Data Upload menu item. This should start uploading the files into ESP8266 flash file system. When done, IDE status bar will display SPIFFS Image Uploaded message. Might take a few minutes for large file system sizes.
