Re: [Buildroot] How to connect to Wifi on start-up using Buildroot?

[Jan Havran]

Hi Sourabh,

after enabling RPi firmware you must load the Wifi driver - since you are using
systemd, it should by handled by udev on start I think.

So you probably just need to configure /etc/network/interfaces to start wpa_supplicant
on wlan0 with /etc/wpa_supplicant.conf file, where you can put your credentials.
Or at least that is what I have done, but I am not using systemd.

I did something similar some time ago, you can check it here:
https://gitlab.com/sonicpp/gnss-pi/-/commit/caf0317c024e51fc7e322deacd09ec9346d47e26

(note that to make "my" credentials public in that commit was an intention).

P.S.: if you want to have any modifications to be part of your image with filesystem,
you can do it by using rootfs overlays for example:
https://buildroot.org/downloads/manual/manual.html#rootfs-custom

Jan Havran

[-- Attachment #1.1.1: Type: text/plain, Size: 3213 bytes --]

Helllo Jan,

Thanks for the answer.

From Buildroot 2021 release "ctrl_interface" is disabled and so I have
commented out below line in etc/wpa_supplicant.conf file

# ctrl_interface=/var/run/wpa_supplicant

And also in my rootfs, there is no "/var/run/wpa_supplicant" file.

I have set below options in menuconfig

[image: menuconfig.PNG]

Then doing make clean & make results in below errors:

>>> wpa_supplicant 2.10 Installing to staging directory
/usr/bin/install -m 0644 -D
/root/raspcm4/sources/output/build/wpa_supplicant-2.10/wpa_supplicant/libwpa_client.so

Can you please let me know what could be the issue and how to resolve it?

Thanks in advance

  This shouldn't be needed. AFAIK wpa_supplicant ignores the option if 
CTRL_IFACE is not enabled.

  The file (actually, named pipe) is created when wpa_supplicants starts up. 
/var/run is a tmpfs so it can only be created at runtime.

  I've tried to build the same configuration (with current git master) and it 
builds without problems.

  Please supply the defconfig and also the full build log (by uploading to a 
pastebin).

Re: [Buildroot] How to connect to Wifi on start-up using Buildroot?

[Sourabh Hegde]

[-- Attachment #1.1: Type: text/plain, Size: 6674 bytes --]

Hello Peter,

In my local Buildroot package folder I don't have
"0001-build-re-enable-options-for-libwpa_client.so-and-.patch"
file.
Can you please let me know how to include this file? This is my first time
applying patches in Buildroot. I have downloaded patch file(tar.bz2). I
assume copying patch file to wpa_supplicant dir and running "make clean &&
make" will apply this patch. Please correct me if I am wrong.

And also I tried below to assign IP address to my board (RPi CM4)

wpa_supplicant -B -Dnl80211 -iwlan0 -cwpa_supplicant.conf
udhcpc -i wlan0

But this gives:

udhcpc: started, v1.35.0
udhcpc: broadcasting discover
udhcpc: broadcasting discover
udhcpc: broadcasting discover
udhcpc: broadcasting discover
.
.
.
Is there any other way to assign IP address to the board?

Your help will be much appreciated.

Thanks in advance
