Re: Points to consider while moving to new yocto versions

amaya jindal

Thankyou for your comments and guidance. 

Currently i am trying to first move from krogoth version of yocto to rocko version first that will suffice our requirements but i need to understand whether any major difference is there in gcc 4.9.3 vs gcc 6.4. As krogoth is usin gcc 4.9.3 /5.3 recipe but rocko is using 6.4/7.x as recipe for gcc source compilation. Please guide.

I would consider it "best practice" to somewhat try to stay up to date
with recent yocto versions and plan for this from the beginning of your

What I mean is to have a "stable release" and a "next release" which is
being used in your nightly builds and tests.

This will make it significantly easier to make version upgrades.

I am not sure what you mean by that?

Which versions make it easier/more difficult to support arm?

It's more a question of which chip/kernel/boot loader,...

Ssince you use a completely outdated and end of life version[1] it might
require quite some effort to update, but through pain we learn ;)


Which chip do you use?

Is it supported by an upstream kernel/boot loader?

Which (additional) layers do you use?

Are these layers supported by the same version as the Yocto version you
want to move to?

How about your own recipes?

Are they compatible with upstream yocto?
