Traditionally, the Duet RepRapFirmware is built using the Eclipse IDE. If that is to your liking, then by all means go ahead and do so.

This fork of the RepRapFirmware may also be built using the scons command line tool,

  1. Should your system lack Python 2.x, download and install it.

  2. Download and install scons. Version 2.3.5 or later is required.

  3. Install the Arduino application. Versions 1.5.8beta is known to work. You will merely be using the gcc-arm toolchain installed with/by the Arduino application.

  4. Run the Arduino application and install the ARM programming tools. Look under "Tools > Board > Boards Manager...". Select the "Arduino SAM Boards (32-bits ARM Cortex-M3) by Arduino" and install it.

  5. From this github repository, edit the file

      scons_tools/sample_rrf_arduino_paths.py

    as appropriate to indicate the location of your installed gcc-arm tool chain and location of the CoreDuet sources (Step 6). Then save this file to your home directory as the file

      ~/.rrf_arduino_paths.py

  6. Obtain and build a copy of the github CoreDuet repo.

  7. From the top-level RepRapFirmware repository directory, build the firmware with the command

      scons platform=<board-name>

    where <board-name> is the target board. As of this writing, duet and radds are the accepted target boards. To see the supported target boards, you can issue the command

      python scons_tools/platforms.py

  8. Once scons finishes a build, the resulting files will be in the directory

     build/<board-name>

    The final build product is a .bin file.

  9. For boards with a Native Programming Port and the ATMEGA16U2 Assistant, the scons command

     scons platform=<board-name> upload port=<usb-device>

    may be used to automatically upload the firmware. You do not need to press any buttons on the board to effect the upload.

    For boards which lack a Native Programming Port or the ATMEGA16U2 Assistant, you can use the above command but first you will need to press the board's ERASE button. Possibly the RESET button as well.

    Boards with an attached Arduino Due should have a Native Programming Port as well as the ATMEGA16U2 Assistant (e.g., RADDS).
