Hi,

I'm pretty new on yocto project/tools and I'm trying to build a simple ima=
ge for running a raspberry PI 3.
The raspberry starts well and works well with eth0 network interface. Howe=
ver wlan0 interface seems to not be working.

When trying to start manually the interface I get these messages

ifup wlan0
Successfully initialized wpa_supplicant
rfkill: Cannot get wiphy information
Could not read interface wlan0 flags: No such device
WEXT: Could not set interface 'wlan0' UP
wlan0: Failed to initialize driver interface
ip: SIOCGIFFLAGS: No such device
Here is my local.conf excerp for installing wlan for my image :
ENABLE_UART =3D "1"

DISTRO_FEATURES_append +=3D " bluetooth wifi bluez5"
IMAGE_INSTALL_append +=3D " linux-firmware bluez5 wpa-supplicant"
I'm pretty sure that someone has already=C2=A0done this before me ;)
Could you tell me if I miss something ?

Regards,
