[Buildroot] Wifi not working - raspberrypi3_defconfig

[Ola Oni]

Hi Martin,

I was advised to email you about my issue of not been able to get Wifi 
working on raspberry pi 3 using buildroot 2018.11

Below are the entry in my two files [/etc/network/interfaces and 
/etc/wpa_supplicant.conf]

# /etc/wpa_supplicant.conf <- filename
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=root
ctrl_interface_group=0
update_config=1

 ??? network={
 ??????????? ssid="myssid"
 ??????????? psk="mypassword"
 ??????????? proto=WPA
 ??????????? key_mgmt=WPA-PSK
 ??????????? pairwise=CCMP
 ??????????? auth_alg=OPEN
 ??? }

########################################
# /etc/network/interfaces <- filename
# interface file auto-generated by buildroot

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp
 ? pre-up /etc/network/nfs_check
 ? wait-delay 15
 ? hostname $(hostname)

auto wlan0
iface wlan0 inet dhcp
 ??????? wireless-essid "myssid"
 ??????? wireless-key "mypassword"
 ??????? pre-up wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -B
 ??????? post-down killall -q wpa_supplicant

Attached to this is email is the output from dmesg.

Regards

onio

Not much info, Wifi will definitely not work with raspberrypi3_defconfig
out of the box (e.g. package BR2_PACKAGE_WPA_SUPPLICANT not enabled)...

Hi Peter,

Thanks for your reply. I will try and configure later on today and report
back.

May I add that when I use "ps" command wpa_supplicant process seem to be
listed as one of the process running so I assumed that "This is a giving"

So I must have assumed wrong ?

Regards
Ola

[Buildroot] Wifi not working - raspberrypi3_defconfig

[Martin Bark]

Ola,

You also need to include the rpi-wifi-firmware package
(BR2_PACKAGE_RPI_WIFI_FIRMWARE)
and make sure the brcmfmac module is installed.  You should see messages
about brcmfmac in your logs

Thanks

Martin

Seems you have BR2_PACKAGE_WPA_SUPPLICANT already enabled...

>

....so you did not use plain raspberrypi3_defconfig (or made already some
changes to it)...., from your given examples I suspect your followed this
receipe [1]? Please provide next time your .config/defconfig (after
savedefconfig) files...

I see no 'brcmfmac' lines in your dmesg output, maybe BR2_PACKAGE_RPI_WIFI_FIRMWARE
not enabled? Or your did not change to BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_MDEV?

Or something with your config files, make sure to only use plain spaces (after copying
from your email I got no plain spaces as indent but some UTF-8 spaces)...

raspberrypi3_defconfig with the following changes works for me:

+BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_MDEV=y

+BR2_PACKAGE_RPI_WIFI_FIRMWARE=y
+BR2_PACKAGE_DHCPCD=y
+BR2_PACKAGE_WPA_SUPPLICANT=y

Peter

Hi Peter,

I am rebuilt the raspberry pi 3 buildroot image which has now allowed me 
to see wlan0 when I issue ifconfig but still can't seems to connect to 
WiFi network.

Attached is a file which I have appended my current rpi3_defconfig and 
other outputs. Many thanks in advance.

Regards
Ola

- configs/rpi3_defconfig: looks good
- dmesg: looks good (brcmfmac messages exist)
- my /etc/network/interfaces (no wireless-... entries):

# interface file auto-generated by buildroot
  
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp
  pre-up /etc/network/nfs_check
  wait-delay 15
  hostname $(hostname)

auto wlan0
iface wlan0 inet dhcp
  pre-up wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -B
  post-down killall -q wpa_supplicant

- my /etc/wpa_supplicant.conf (only the bare minimum):

network={
    ssid="my ssid"
    psk="my password"
}


Run wpa_supplicant with debug enabled (-dd)...double check ssid/psk?

Peter

Hi Peter,
WiFi is now working. Enabling the wpa_supplicant in debug mode revealed 
that there was an old file /var/run/wpa_supplicant/wlan0 that it wanted 
me to "delete" which I simply renamed.

I then proceed to running again but then I realized that I forgot to 
kill the original wpa_supplicant which was automatically started.

Killing this process and issuing the wpa_supplicant directly from the 
command line kicked things into life.

Thank you for your support highly appreciated.

Regards

Ola
