This repository contains the source for an Ubuntu Core gadget snap that runs universally on all Raspberry Pi boards currently supported by Ubuntu Core (Pi2, Pi3, Compute Module 3).
It comes with a splash screen by default and produces a completely silent boot.
Building it with snapcraft will automatically pull, configure, patch and build the git.denx.de/u-boot.git upstream source for the pi2 at release tag v2017.05 (for pi3/cm3 at tag v2018.07), produce a u-boot.bin binary and put it inside the gadget.
It will then download the stable binary boot firmware with tag 20180619 from https://github.com/raspberrypi/firmware/tree/stable/boot and add it to the gadget.
Last it will pull the latest linux-image-raspi2 from the bionic-updates archive, extract the devicetree and overlay files from it and add them to the gadget as well.
The splash screen included comes from git://git.yoctoproject.org/psplash. Please see the psplash/ sub directory for patches and adjustments in use.
Gadget snaps are a special type of snaps that contain device specific support code and data. You can read more about them in the snapcraft forum: https://forum.snapcraft.io/t/the-gadget-snap/

This gadget snap comes with a boot splash. To change the logo you can add a new png file to the psplash subdirectory of this tree, adjust the "SPLASH=" option in psplash/config to point to this file and rebuild the gadget.
To turn off the splash screen completely please edit configs/cmdline.txt and remove
the splash and the vt.handoff=2 keywords from the default kernel commandline.
This gadget snap can only be cross built on an amd64 machine. To do so, just run snapcraft
in the top level of the source tree after cloning it to a PC.
