blurfl / makeUF2-tool

A tool for the Arduino IDE to make a UF2 file from a compiled sketch binary .bin file.

Arduino UF2 file creator

Arduino plugin which creates a .uf2 file from a .bin file located in the sketch folder.
Tested with the following Arduino IDE versions: 1.8.8

Installation

• Make sure you use one of the supported versions of Arduino IDE.
• Download the tool archive from the releases page.
• In your Arduino sketchbook directory, create tools directory if it doesn't exist yet.
• Unpack the tool into tools directory (the path will look like <home_dir>/Arduino/tools/makeUF2/tool/makeUF2.jar).
• 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).
• Make sure you have selected the proper board.
• Create a compiled binary image of the sketch: (choose Sketch > Export compiled Binary).
• Select the Tools > makeUF2 - UF2 file creator menu item. This will create a UF2 file from the compiled binary and place it in the sketch folder. Copy that file onto your xxxxBOOT disk to install it.
