...\arduino-1.5\hardware\arduino\avr\platform.txt
To:
...\arduino-1.5\hardware\tiny\avr\platform.txt[/quote]
Ugh. That's a maintenance nightmare. If the Arduino folks change the build process (e.g. add new options to go with a new compiler) the Tiny Core will still use the "old" process.
Unfortunately, the IDE crashes if that file is not present.
Does anyone know of a way to reference the platform.txt file in the Arduino IDE directory?
