            Bug ID: 15546
           Summary: raspberry pi zero 2 w no Wi-Fi device
           Product: buildroot
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: minor
          Priority: P5
         Component: Other
          Assignee: unassigned@buildroot.uclibc.org
          Reporter: glscene2010@gmail.com
                CC: buildroot@uclibc.org
  Target Milestone: ---

I use raspberry pi zero 2 w. I use master branch Buildroot.
Full steps here https://forums.raspberrypi.com/viewtopic.php?p=2100121#p2100121 
Summary my steps:
I add this tree lines in raspberrypizero2w_defconfig
BR2_PACKAGE_BRCMFMAC_SDIO_FIRMWARE_RPI=y
BR2_PACKAGE_BRCMFMAC_SDIO_FIRMWARE_RPI_BT=y
BR2_PACKAGE_BRCMFMAC_SDIO_FIRMWARE_RPI_WIFI=y
And build: 
make clean -C buildroot
make  -C buildroot raspberrypizero2w_defconfig
make -C buildroot

But there is no Wi-Fi device. 
I know how manually enable Wi-Fi in Buildroot for raspberry pi zero 2 w, do:
modprobe brcmfmac
/etc/init.d/S40Network restart

Why Buildroot don't do it by himself?

Hello, 

I have a fix, but I don't have a board to test , could you please test it on
yours and tell me if it works ?

Hi Taib,
This is a compiled Buildroot image that you have provided thus, asking others
to run this image poses a potential security risk for some.
In the future, instead of asking others to test a binary, can you share what
you did to resolve the issue so that we can reproduce on our end.
Thanks!
Sincerely,
Jose

I try sdcard.img
I boot and ask
uname -a 
Linux buildroot 5.10.92-v7 #1 SMP Tue Aug 1 22:21:04 CEST 2023

Let's check our problem
ifconfig -a
says again only one lo device. The same problem, nothing happen.
After I do
modprobe brcmfmac
/etc/init.d/S40Network restart
I can see wlan0 device.
P.S. May be this problem because of old kernel?

I ran into this on a Pi 0 W; the module isn't loaded because there's no udev by
default, which creates device files but also loads modules for available
hardware. You can enable it under System configuration -> /dev management, I
chose 'Dynamic using devtmpfs + mdev', that is,
CONFIG_ROOTFS_DEVICE_CREATION_DYNAMIC_MDEV=y.
