Raspberry Pi 3 Gadget Snap

This repository contains the source for an Ubuntu Core gadget snap for the Raspberry Pi 3.

Building it with snapcraft will automatically pull, configure, patch and build the upstream source for rpi_3_32b_defconfig at release v2017.05, produce a u-boot.bin binary and put it inside the gadget.

It will then download the latest stable binary boot firmware from and add it to the gadget.

Last it will pull the latest linux-image-raspi2 from the xenial-updates archive, extract the devicetree and overlay files from it and add them to the gadget as well.
