[yocto] Deploying Yocto build images

[Michael_E_Brown at Dell.com]

Thanks for posting this. It's very timely for a project I am in the initial stages of designing. I have looked over the docs and some of the code, and am interested in using this.

I would make a couple suggestions:

1)      As you mention, documentation is important. Unless this is very well documented, it's difficult for other people to take up and use effectively, or to advocate for its use in a group

2)      Progress indications: it's going to be fairly important to build in some way to notify other process about the state of the update. A flexible framework for sharing progress would be very much appreciated. There are a couple scenarios I have, but the main one is a network notification where one device is being updated by another. The updated device should be able to signal update progress to the updater device in a flexible fashion. I haven't looked at the code hard enough to see how difficult this would be to add.

Stefano,

This is a really great tool. I'm always developing a new software update tool for each new project, since there are different requirements.
As I can see you are dealing with different scenarios, and this is really amazing.

I'm already cloning meta-swupdate to test it.
Looking at recipes I realized that swupdate is initialized in an sysVinit environment.
Did you plan to use systemd too?
Maybe I can contribute to this.

Thanks for sharing.

Regards,

Hi everybody,

in the last ELCE, David point out in his presentation that we should
improve how to deploy Yocto images on the target.

I did some work this year to provide a reliable way for some customers
of us to install Yocto's images in field, and I have published last week
the sources. Here the link of the announcement:

        http://comments.gmane.org/gmane.comp.embedded.eldk/2397

Mainly, it is a tool that can be stored in the rootfs or will be put in
a separate initrd image and whose goal is only to update the system. I
have tried to describe pros and cons of several different solutions
(updating via bootloader ? single copy against dual copy ?) - you can
find details in the doc directory in the swupdate repository.

Maybe someone of you can find this helpful, and I will be happy if I
could get some feedback.

Best regards,
Stefano Babic
