Location of boards.txt for an Arduino DUE (SAM board)

I use the 1.6.7 Arduino IDE and I’ve installed the "Arduino SAM Boards (32-bits ARM Cortex-M3)" item for my DUE board, and it works fine.

However, I would like to tune some build parameters in my boards.txt file. Problem: I do not have a INSTALL/hardware/arduino/sam folder! I do have the traditional INSTALL/hardware/arduino/avr folder, but in this one boards.txt does not contain the settings for the DUE.

  • Where can the settings of the DUE be found?
  • Should I create myself a new boards.txt file in a new sam/ folder? What should be its default content?

The mystery folder can be found in the Arduino15 directory, which is located under the home folder (not Arduino's install folder; that would be too easy). You can see the path in the Preferences (see below). The boards.txt file is in Arduino15\packages\arduino\hardware\sam\1.6.6.

It seems location changed at least in Linux, Eric Leibenguth answer still directs you to an arduino related folder but no boards.txt there.

Mine was at: /usr/share/arduino/hardware/archlinux-arduino/avr/boards.txt

you can find yours by enabling "Show verbose output during:" "compilation" in preferences and then in the logs it will show somewhere at the beginning something like:

Using core 'arduino' from platform in folder: /usr/share/arduino/hardware/archlinux-arduino/avr

look around that path to find yours
