I've build a Yocto recipe to be used on a Raspberry Pi Zero W, have build it
and save to a SD Card. My recipe has the following layers:
==========================================================================
meta /home/quadfloor/release_1/src/poky/meta 5
meta-poky /home/quadfloor/release_1/src/poky/meta-poky 5
meta-yocto-bsp /home/quadfloor/release_1/src/poky/meta-yocto-bsp 5
meta-oe /home/quadfloor/release_1/src/meta-openembedded/meta-oe 5
meta-python
/home/quadfloor/release_1/src/meta-openembedded/meta-python 5
meta-multimedia
/home/quadfloor/release_1/src/meta-openembedded/meta-multimedia 5
meta-networking
/home/quadfloor/release_1/src/meta-openembedded/meta-networking 5
meta-raspberrypi /home/quadfloor/release_1/src/meta-raspberrypi 9
meta-mender-core
/home/quadfloor/release_1/src/meta-mender/meta-mender-core 6
meta-mender-raspberrypi
/home/quadfloor/release_1/src/meta-mender/meta-mender-raspberrypi 10
meta-stargazer /home/quadfloor/release_1/src/meta-stargazer 6
The meta-stargazer has the custom network configuration:
meta-stargazer/conf$ cat layer.conf
# We have a conf and classes directory, add to BBPATH
BBPATH .= ":${LAYERDIR}"
# We have recipes-* directories, add to BBFILES
BBFILES += "${LAYERDIR}/recipes-*/*/*.bb \
${LAYERDIR}/recipes-*/*/*.bbappend"
BBFILE_COLLECTIONS += "meta-stargazer"
BBFILE_PATTERN_meta-stargazer = "^${LAYERDIR}/"
BBFILE_PRIORITY_meta-stargazer = "6"
LAYERDEPENDS_meta-stargazer = "core"
LAYERSERIES_COMPAT_meta-stargazer = "kirkstone"
meta-stargazer/recipes-core$ cat systemd/systemd_%.bbappend
PACKAGECONFIG:append = " networkd resolved"
RDEPENDS:${PN}:append = " wpa-supplicant "
meta-stargazer/recipes-core$ cat systemd-conf/systemd-conf_%.bbappend
FILESEXTRAPATHS:prepend := "${THISDIR}/files:"
SRC_URI += " file://eth.network file://en.network file://wlan.network "
FILES:${PN} += " ${sysconfdir}/systemd/network/eth.network
${sysconfdir}/systemd/network/en.network
${sysconfdir}/systemd/network/wlan.network "
do_install:append() {
install -d ${D}${sysconfdir}/systemd/network
install -m 0644 ${WORKDIR}/eth.network ${D}${sysconfdir}/systemd/network
install -m 0644 ${WORKDIR}/en.network ${D}${sysconfdir}/systemd/network
install -m 0644 ${WORKDIR}/wlan.network ${D}${sysconfdir}/systemd/network
}
meta-stargazer/recipes-core$ cat systemd-conf/files/wlan.network
[Match]
Name=wlan*
KernelCommandLine=!nfsroot
[Network]
DHCP=v4
[DHCPv4]
UseHostname=false
meta-stargazer/recipes-core$ cat systemd-conf/files/en.network
[Match]
Name=en*
KernelCommandLine=!nfsroot
[Network]
DHCP=v4
[DHCPv4]
UseHostname=false
meta-stargazer/recipes-core$ cat systemd-conf/files/eth.network
[Match]
Name=eth*
KernelCommandLine=!nfsroot
[Network]
DHCP=v4
[DHCPv4]
UseHostname=false
When I boot the Raspi, there are no error messages related to wlan in the log
("dmesg | cat wlan" shows nothing), but when I issue ifconfig -a, I find only
the lo interface.
There are several posts on Raspi forum regarding updating the RaspiOS to solve
that, but I don't know how to handle that on Yocto. I'm stuck with no network
connection so any help is very much appreciated.
