How to configure networking using systemd in Yocto Project

I’m trying to boot up a Raspberry Pi Zero W with WiFi.

After some days struggling with this, compiling, recompiling, I still cannot see the wlan0 interface on Raspberry Pi Zero W.

ifconfig shows only the lo interface:

I’ve followed all the step 7 and I’m getting the following error when booting up (in picture above):

$ dmesg | grep wlan
[    5.819020] systemd[1]: multi-user.target; Wants dependency dropin /etc/systemd/system/multi-user.target.wants/wpa_supplicant-nl80211@wlan0.service target /lib/systemd/system/wpa_supplicant@.service has different name

I’m using Yocto Kirkstone version.

Here is are my current configuration files:

I’ve tried ElioDream’s comment and changed configuration, but still same error.

I’ve installed RaspiOs to check hardware defect and the WiFi works nicely…

No idea of what can be done to solve this - I’m really with no ideas - help appreciated…
