How to Build all cores for custom raspberry Pi 3 board


I am trying to understand what it requires to build all snaps.
From the below link, I am able to build a raspberry Pi 3 image.

Can I build without being connected to cloud/internet. Can we get the source of snaps and work with them locally.

we don’t plan to change anything in core/kernel snap but we want to know how they are get built and their source.


Hey @muthiah most of the sources are stored by an cloud provider like GitHub, Launchpad/Ubuntu,

Why you not download just the snaps with snap download from an Pi3 device?

snap download pi2-kernel

as example.

And so you can build images with the ubuntu-image tool as

–extra-snaps pi2-kernel.snap
