SolidRun Hummingboard Gadget Snap

Snap Status

This repository contains the source for an Ubuntu Core gadget snap for the SolidRun Hummingboard. Building it with snapcraft will automatically pull, configure, patch and build the git.denx.de/u-boot.git upstream source for mx6cuboxi_defconfig at release v2017.01 and produce a bootable gadget snap with the resulting binaries.

Gadget Snaps

Gadget snaps are a special type of snaps that contain device specific support code and data. You can read more about them in the snapd wiki https://github.com/snapcore/snapd/wiki/Gadget-snap

Building

Natively on armhf

To build the gadget snap locally on a native armhf system just run snapcraft in the toplevel of the tree.

Cross on x86 systems

Copy the crossbuild-snapcraft.yaml over snapcraft.yaml and run snapcraft

cp crossbuild-snapcraft.yaml snapcraft.yaml
snapcraft

Splash screen

The splashscreen has been created from a jpeg with the following line:
