I am planning on working on a project to bring support for this board to Nerves Project which means that we will need to integrate flashing with our existing tooling. I downloaded a copy of the arduino-flasher-cli from the Arduino homepage, and was pleased to find that the binaries are distributed with a copy of GPL-3.0. I can't, however, find the project source anywhere. I'd love to see how the project uses QDL to write the Debian image to the eMMC because we will be wanting to use a similar method to write our buildroot-based OS image.
