Hi Jon,
Thank you for the answer.
When making any custom changes in Yocto, your always going to want to
create your own meta layer so that you can keep your changes separate
and so you can revision control your stuff.
Yes, this was sort of intuitive to me. That is how I started to manage
my custom project based on Yocto here:
https://github.com/Beaglenode/BeagleNodeOs/tree/setup_config
I have created this short script (still under development) that does the
preconfigurations (adding or removing layers and so on):
https://github.com/Beaglenode/BeagleNodeOs/blob/setup_config/setup.sh
I am not sure whether this is the way to go, but could not figure out
any better way with this approach, in which I have my own repo and just
use Poky (and 3rd party layers) as git submodules.
The other "method" I have stumbled upon is how it is done with for
instance openbmc: https://github.com/openbmc/openbmc
The way I see it, its a fork of Poky which is detached from the yocto
repo. This way, any changes can be easily implemented by editing any
needed files. Its more feasible when it comes to changes, but it felt
somehow "not right" to me.
How do you see this topic and the approach I have taken?
This guide from Toradex seems to do a decent job explaining it all.
Though the names of different recipes will have to be adjusted for the
boneblack.
I will check this out, thank you!

Hello,
For a while now I am trying to create a custom device tree overlay for the
BBB/ BBG. It doesn't go so well. I started to think whether it would not be
more feasible to have a custom base dts file instead (just like
`am335x-bonegreen.dts` or `am335x-boneblack.dts`. Based on one of these 2 files
I could create, say, `am335x-bonepink.dts`. Assuming this `am335x-bonepink.dts`
would reside in some dir I have access to, what would be the preffered Poky way
of implementing it into the build? By that I mean that during bitbake it would
be compiled to a *.dtb and placed in the boot directory along with the other
dtb files. Do I need to create a custom recipe/ layer for that and add it to
the build via `bitbake-layers add-layer`? If yes, how would the steps look like
in practice (I am quite new to Yocto/ Poky)?
I would appreciate all feedback!
