Hi Zoran,
I'm not sure I got your question correct but I'll try to give you a
super simple network config for systemd-networkd using dhcp.
Add the file '/etc/systemd/network/10-dhcp.network' with the following
content:
[Match]
Name=*
[Network]
DHCP=yes
Then I hope you will get your interface up with DHCP.
Regards,
/Peter

Hello Nicolas,
I build ONLY initramfs to be used on BBB DUT in order to test VMs. I
do not use mtd neither flash rootfs (as mounted on flash), although in
the BBB DUT's flash I have embedded Debian stretch. I use different
ash scripts in U-Boot to bring only ramboot.
Here is the proof:
root@beaglebone:~# df
Filesystem 1K-blocks Used Available Use% Mounted on
devtmpfs 213596 0 213596 0% /dev
tmpfs 251260 0 251260 0% /dev/shm
tmpfs 251260 8428 242832 3% /run
tmpfs 251260 0 251260 0% /sys/fs/cgroup
tmpfs 251260 0 251260 0% /tmp
tmpfs 251260 116 251144 0% /var/volatile
But this email thread, my best guess, addresses your concerns:
https://lists.yoctoproject.org/pipermail/yocto/2018-July/041680.html
There is also how to build image with initramfs ONLY, in this thread,
written by me:
https://lists.yoctoproject.org/pipermail/yocto/2018-July/041696.html
thanks, that exactly what I was looking for.
I hope this helps.

Hello Lukasz,
Thank you very much for the advises. I did what you have suggested, and this
does work.
And it solves my basic problem (NO GO for some reason when I had network
manager).
I use DUT (BBB) with YOCTO initramfs linux as testing vehicle for my various
pass-through VBox VMs (several designs) via my notebook host to test them, how
different designs VMs connect and interact with DUT.
can you share how you built your initramfs? Are you saying that you
are booting an initramfs which then mounts the rootfs where you have
core-image-minimal?
Lukasz and Peter,
I also will investigate more about systemd service in order to get more inside
info about how to properly configure the service.
Thank you,
Zoran

I have two questions (please, could you provide to me some help here):
[1] How to fix this run-time bug (what I should do in the configuration)?
I found some interesting explanation about possible solution
(PACKAGECONFIG):
https://lists.yoctoproject.org/pipermail/yocto/2013-November/016965.html
Probably you are missing CONFIG_CGROUPS in your kernel configuration.
Please read README file in the systemd sources folder - it describes all options
required to be enabled in kernel configuration.
[2] I would like also to include networkctl service (should I do something
specific to
enable it, or this is done by default enabling systemd)?
Please add following to your conf/local.conf file:
PACKAGECONFIG_append_pn-systemd = " networkd"

Lukasz Zemla
