[Buildroot] [RPi3] Trying to test WiFi On Raspberr Pi 3

[Buildroot] [RPi3] Trying to test WiFi On Raspberr Pi 3

[Oscar Gomez Fuente]

Hi everyone,

I'm trying to check the broadcom WiFi module BCM43438 of the RPi3B. By
default the package:

Target Package --> Hardware handling  ---> Firmware  ---> linux-firmware
---> Ethernet firmware  ---> Broadcom BRCM bcm43xxx

It's not selected. But when I select this package, I've got this error:

# dmesg | grep brcm
[    7.127904] brcmfmac: brcmf_sdio_drivestrengthinit: No SDIO Drive
strength init done for chip 43430 rev 1 pmurev 24
[    7.145814] usbcore: registered new interface driver brcmfmac
[    7.162030] brcmfmac_sdio mmc1:0001:1: Direct firmware load for

[    8.186873] brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000):

[    9.215286] brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000):
clkctl 0x50

So I noticed that the binary brcmfmac43430-sdio.bin and
brcmfmac43430-sdio.txt it isn't copy by the linux-firmware package to
/lib/firmware/brcm folder, so I've tried to copy the files
brcmfmac43430-sdio.* manually  to /lib/firmware/brcm (I should be a great
idea to add this files to the linux-firmaware package) and now I didn't get
any error:

[    7.101997] brcmfmac: brcmf_sdio_drivestrengthinit: No SDIO Drive

[   10.217086] brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000):
clkctl 0x50

But I can see the wlan0 device. I list the folder :

# ls  /sys/class/net/
eth0  lo

And the wlan0 doesn't appear.

I've tried this command:

# iw dev wlan0 set
command failed: No such device (-19)

Does anyone know how can I solve this problem?


Best regards.

[Buildroot] [RPi3] Trying to test WiFi On Raspberr Pi 3

[Oscar Gomez Fuente]

Hi everyone,

I've got updates in my WiFi issue. I had to install the following package:
crda, iw & wireless-regdb, and now I've got another log kernel:

I see this message wit the region unset:
[5.651915] cfg80211:  DFS Master region: unset

So I've changed the region with the command:
iw reg set ES

And this is the log now:

But when I execute the command:
# iw dev wlan0 link
command failed: No such device (-19)

So it seems to be the device doesn't exist (Althoug I added the wlan0 to
the /etc/network/interface manually).

Any suggestions?

Best regards.

I have the same issue with this chip on the board I'm working on. I have
found out that if I unload and reload the module it then works.

Hi,

I've just solved the problem. First of all, you have to download the
firmware from this git repository: https://github.com/OpenELEC/wlan-firmware

Then you have to select the following packages on buildroot:  crda,
iw,  wireless-regdb and wpa_supplicant.

You have to modify the /etc/network/interfaces in the post-build.sh script:
-----
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp
        pre-up /etc/network/nfs_check
        wait-delay 15

auto wlan0
iface wlan0 inet dhcp
        pre-up wpa_supplicant -B -Dwext -iwlan0 -c
/etc/wpa_supplicant/wpa_supplicant.conf
        post-down killall -q wpa_supplicant

iface default inet dhcp
-----

And you have to add this other file in
/etc/wpa_supplicant/wpa_supplicant.conf, with SSDI and XXXXXXXXX...
correctly (for example in the post-build.sh script):
-----
network={
        ssid="SSID"
        scan_ssid=1
        proto=RSN WPA
        key_mgmt=WPA-PSK
        pairwise=CCMP TKIP
        group=CCMP TKIP
        auth_alg=OPEN
        priority=0
        id_str="name"
        #psk="xxxxxxxxxx"
        psk=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXxxxx
}

And these changes works fine.

So It will be very useful to add the files brcmfmac43430-sdio.bin and
brcmfmac43430-sdio.txt to the linux-firmware package.

Best regards.

I don't think these are available in linux-firmware. It seems like we
need to get them from rpi-firmware-nonfree:

[Buildroot] Fwd: [RPi3] Trying to test WiFi On Raspberr Pi 3

[Oscar Gomez Fuente]

Hi Peter,

I've tried with both repositories, the RPi-Distro [
https://github.com/RPi-Distro/firmware-nonfree/tree/master/brcm80211/brcm]
and OpenELEC [ https://github.com/OpenELEC/wlan-firmware] both works fine.
It seems to be they are the same bin file (I made a kompare between them).

But the questions is, Could anyone add this files to the linux-firmware
package, or Could we create a new build package called
linux-firmware-nonfree with this files? I don't have any idea If we can get
this files from a legal point of view.

Best regards.
