I've it installed previously from a USB thumb drive onto a much bigger SSD with all partitions setup. I don't need to change the partition from here onward. Is there an easy way to replace it with, say 2017 Oct release (Rocko) Poky image (and vice versa)? E.g. by replacing just one file (e.g. bzImage)? Or is there a script that would take care of it? What happens to all the existing directories, e.g. /etc, /bin etc.? I've been trying to adapt init_install.sh under poky/meta/recipes-core/initrdScripts/files, but it seems to assume I've a separate device (like USB drive).

The question has no connection to a specific Yocto release at all. If I rephrase the question it becomes "How do I upgrade my Linux system at all?". Take a look at ResinOS partition scheme here: https://www.balena.io/docs/reference/OS/overview/2.x/#image-partition-layout May be it can shed a bit of a light. --- Kosta Z. ^ permalink raw reply [flat|nested] 3+ messages in thread
