Dfu-programmer Installation

To flash an AT90USB-based board the tool dfu-programmer needs to be installed on the OctoPrint host.

Linux (including Raspberry Pi)

A version of dfu-programmer can be installed via apt-get install but it is outdated. Please build the latest version from Github using these commands:

cd ~
sudo apt-get install autoconf libusb-1.0-0-dev
git clone https://github.com/dfu-programmer/dfu-programmer.git
cd dfu-programmer
./bootstrap.sh
./configure 
make
sudo make install

If there were no errors dfu-programmer should now be installed at /usr/local/bin/dfu-programmer.

Dfu-programmer Configuration

Firmware Updater

Required Settings

The minimum settings are:

  • AVR MCU Type
  • Path to dfu-programmer

Optional Settings

Option Description
Erase command line The command used to erase the board prior to flashing.
Flash command line The command used to flash the firmware to the board.

Hardware Notes

AT90USB boards must be in Boot or DFU mode before they can be flashed. This is done by placing or removing a jumper then resetting the board.

Printrboard DFU Mode

To put a Printrboard board into DFU mode:

  • Remove the BOOT jumper (for Rev D, E & F boards, install the BOOT jumper)
  • Press and release the Reset button.
  • Replace the BOOT jumper onto the board (for Rev D, E & F boards, remove the BOOT jumper)

The board will now be ready for flashing. Once flashing is complete press the Reset button again to return to normal operation.
