Only on a Raspberry Pi 3 so far (uboot supported is already present for it).

Thanks Jaquier, did you run mender in an embedded system?

Hi,

I've been experimenting with mender a bit lately. Works great so far and
it's fully integrated into yocto:

There are a few other solutions available for Yocto:

and boot

Hi,

Are there any Yocto recipes to support dual version control for
firmware image upgrade and boot?

The scenario is to make 2 partitions, one partition to install a work
version of image, say v1.0, another partition to install a development
version of image, say v1.1, the boot process should pick up the
highest the version v1.1 first, if it fails to boot, it retreats back
to boot old version v1.0.

Appreciate any tips or reference for that implementation in Yocto.

Thank you.

Kind regards,
