the symlink appears. But for some reason I have to always restart the service(systemd-networkd) to get it work.
On every bootup. This started happening only after I moved .network file to my persistent data.

Check that networkd is not running before data partition is mounted
Assuming you have systemd-analyze installed
run āsystemd-analyze plot > services.svgā
copy the svg to your machine and open in your image viewer (chrome will open it nicely and make it searchable)
and see if data.mount is happening later than systend-networkd
please give me a few minutes. I have to install systemd-analyze
I suspect that might be happening.
But even then. I would think that it wouldnāt run on the first boot. But subsequent bootup should not be having a problem right?
I would expect it to happen everytime as the symlink is broken at the point that systemd-networkd runs
I think you are right. I see my systemd-networkd service starting early than data mount.
Here is my services.png file. It might need a lot of zoom
Now in order to delay my network service. Do I have to create a patch of sorts and call that in a systemd_%.bbappend file?
I would start by using the normal systemd extend mechanism
add a file called something like 99-before-networkd.conf to your recipe folder files folder (must end in .conf)
in this file add the following
[Unit]
Before=systemd-networkd.service
add a SRC_URI entry for it in your bbappend file and add to your FILES variable just like you have done for your .network file.
in your do_install_append() function install the file to
/etc/systemd/system/data.mount.d/99-before-networkd.conf
https://www.freedesktop.org/software/systemd/man/systemd.unit.html#
That did the trick.
@drewmoseley Iāve got it to work by linking wpa_supplicant-nl80211@.service instead of wpa_supplicant@.service.
In this case, it will go fetch the correct conf file (wpa_supplicant-nl80211@wlan0.conf)
ln -s ${systemd_unitdir}/system/wpa_supplicant@.service ${D}${sysconfdir}/systemd/system/multi-user.target.wants/wpa_supplicant-nl80211@wlan0.service
becomes
ln -s ${systemd_unitdir}/system/wpa_supplicant-nl80211@.service ${D}${sysconfdir}/systemd/system/multi-user.target.wants/wpa_supplicant-nl80211@wlan0.service
Welcome and yer thatās what had to to do also
hi,
is there a specific reason as why not to use the default /etc/wpa_supplicant.conf
for configuration?
Hi @simonbuehler,
just because it is not persisted across system updates by default: the A/B partitions should be treated as completely transient. For anything that requires persistence, moving out to /data
for example is needed.
Greetz,

Iām 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:
Iāve followed all the step 7 and Iām 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
Iām using Yocto Kirkstone version.

Iāve tried ElioDreamās comment and changed configuration, but still same error.
Iāve installed RaspiOs to check hardware defect and the WiFi works nicelyā¦
No idea of what can be done to solve this - Iām really with no ideas - help appreciatedā¦
