[yocto] Newbie Question regarding custom layer and populate_rootfs

Hi Stephan, hi Herrie,

thank you for your replies to my question.

I have finally added a machine raspberry2p which includes the original
raspberrypi2 machine definition - and then defines another SPLASH reference.
That worked.

What helped my a lot were the commands

bitbake-layers show-layers and
bitbake -g </image>/ && emacs pn-depends.dot

That reference is a really valuable link!

Thank you and best regards
