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

[Oscar Gomez Fuente]

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.
