what I wanted to do:
flash main SIMtrace 2 application on SIMtrace using USB DFU

what environment am I using:

• Linux Arch amd64 2018-05-21 up to date
• dfu-util v0.9
• arm-none-eabi-gcc 8.1.0
• SIMtrace v1.4 board with SAM3S micro-controller
• simtrace2 git, branch laforge/simtrace, commit 849d20e29e3b8ff1d40e3b012849f78ded3be734
• USB DFU bootloader flashed over JTAG

what I did:
sudo dfu-util --device 1d50:60e3 --alt 0 --download ./bin/simtrace-cardem-dfu.bin

what I expected:
successful firmware download

what I got:
dfu-util: Invalid DFU suffix signature
dfu-util: A valid DFU suffix will be required in a future dfu-util release!!!
