Raspberrypi4 WiFi is not working using core-image-full-cmdline

[kottoz]

As i see in the documentation that wifi is already added by default to core-image-base, i have test it and wifi works well. However when i use core-image-full-cmdline, wifi doesn't work.
when i run 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

run ifconfig -a

i have checked #576, #703, and #729.
so, could i add IMAGE_INSTALL_append = " linux-firmware-bcm43455 but it have been added here

bootlog.txt
local.txt
bblayers.txt

After some research i find that

MACHINE_EXTRA_RRECOMMENDS variable affects only images based on packagegroup-base, which does not include the core-image-minimal or core-image-full-cmdline images.

according to #184

core-image-minimal.bb", even though it inherits from core-image.bbclass it sets IMAGE_INSTALL and not appending to it, which overwrites anything that core-image has added to it basically.

Even the Yocto docs mentions this (if you read it all :))

A list of machine-specific packages to install as part of the image being built that are not essential for booting the machine. The image being built has no build dependency on this list of packages.

This variable affects only images based on packagegroup-base, which does not include the core-image-minimal or core-image-full-cmdline images.

So it depends on what the intentions of the rpi-hwup-image is, to decide if this is a bug or not.

One way to make sure it is included by default is to use the

MACHINE_ESSENTIAL_EXTRA_RDEPENDS

variable instead of the

 MACHINE_EXTRA_RRECOMMENDS

in the machine configuration files or just change the "rpi-hwup-image" to inherit directly from core-imageand not from core-image-minimal.

So i have tried to edit raspberrypi4.conf file by replacing MACHINE_ESSENTIAL_EXTRA_RDEPENDS instead of MACHINE_EXTRA_RRECOMMENDS, but it doesn't work
first i add firmware files brcm using IMAGE_INSTALL_append = " iw linux-firmware-bcm43455 wpa-supplicant"
then check firmware.

then i goto pi4 to check and it doesn't work.

@kraj, could you give me hints!

[kraj]

@kraj, could you give me hints!

Use yoe distro and see if it works ok with yoe-simple-image

[agherzan]

Does it work with core-image-base?

[kottoz]

@agherzan ya, it works fine.

[gitgonewithwind]

@kottoz
do you find the solution? I have the some issue with core-image-full-cmdline ?
I do not know how to enable the wifi work.
It seems that you closed the issue, but I read them , I do not find your solution.
before I do not use the pi 4 wiki function with core-image-full-cmdline, but one of our projects will use it
any help?
I have to switch to core-image-base?
what different between core-image-full-cmdline and core-image-base ?
any help?

[agherzan]

I've replied in the issue you've created above.

@agherzan thanks
