Issue with wifi configuration on Raspberry Pi 3
With a basic build of OpenADK for the Raspberry Pi 3, I'm getting the following error when I try to bring up wlan0. # ifup wlan0 ip: SIOCGIFFLAGS: No such device command failed: No such device (-19) Successfully initialized wpa_supplicant Could not read interface wlan0 flags: No such device nl80211: Driver does not support authentication/association or connect commands nl80211: deinit ifname=wlan0 disabled_11b_rates=0 Could not read interface wlan0 flags: No such device wlan0: Failed to initialize driver interface ip: SIOCGIFFLAGS: No such device In /etc/network/interface, I have the following configured: auto wlan0 iface wlan0 inet dhcp wireless-ssid HomeWiFi wireless-mode sta wireless-security wpa2 wireless-passphrase XXXXXXXXXXXX I presume there is an additional configuration for OpenADK required to enable wlan0 on the Raspberry Pi 3, but I don't see anything obvious. I have the 'iw' and 'wpa_supplicant' packages enabled, but that doesn't seem to be the issue. Any tips on what I might be missing? Thanks, Mike Thompson

I do not think you missed anything, it is just a Bug. I once started to try to make it work, but got distracted. I look into it again. Strange thing, I installed Libreelec for Testing on my RPI3 and even this did not recognized the Wifi device. I am starting now with Raspbian to see what I am missing. Hard to find an detailed information, which Linux kernel config symbols are required and what firmware files need to be installed. best regards Waldemar
Hi While I haven't tried to use wifi in ADK, I do remember it worked for me in libreelec on my Pi 3 model B+ At least it showed the available wifi networks. I did not connect to one since I am using the wired connection. If there's anything I can do to help, i.e. test on the B+, let me know! Cheers Oliver On 27.05.2018 18:03, Waldemar Brodkorb wrote:

It could also very well be that you just need to wail for wlan0 interface at startup because it is not yet ready when trying to configure it? I added this in my /etc/init.d/network scripts’ start-function: echo "Waiting for wlan0 ... " waittime=30 while [ ! -d /sys/class/net/wlan0 ] && [ $waittime -gt 0 ]; do sleep 1 let waittime=$waittime-1 done if [ ! -d /sys/class/net/wlan0 ]; then echo "ERROR: Did not find wlan0 interface after 30 seconds" fi ifup -a > /dev/null

OK, thanks. I'll see if I can get time to understand what the issue might be. During some initial research I did come across a brief description of a hardware problem with the Raspberry Pi 3 Wifi that may be related. https://benjaminknofe.com/blog/2017/12/19/fix-broken-onboard-wifi-on-a-raspb... Getting Wifi isn't terribly important to me, but it would be nice to see it working. Mike On Sun, May 27, 2018 at 9:03 AM, Waldemar Brodkorb <wbx@openadk.org> wrote:

What does dmesg say on your device? My device shows -110 errors now. Mike, Oliver, can you retest with latest master? I updated firmware, kernel and wireless firmware and still get mmc1 -110 errors, which looks like a hardware issue with my rpi3 if I interpret the discussions on the net correctly. best regards Waldemar
Hi I get error -2 $ iw dev is empty. dmesg and .config attached Best, Oliver On 28.05.2018 23:39, Waldemar Brodkorb wrote:

I get error -2
But the difference is, the driver is loading, it tries to open and load the binary firmware blob and then fails with error -2. My system fails when the wifi chip is detected on the SDIO bus early not even trying to load any wifi driver at all.

No, it would mean that it is the problem! But, can you just install latest raspbian lite and check if the wireless is working for you? In OpenADK master I added all the firmware blobs from a fresh Raspbian installation. But as long as my rpi3 seems to have broken WLAN I am unable to test. best regards Waldemar
Hi Oops, installed full raspbian, not lite. but yes, it works. I had to set the wifi country first, though. Don't know if that's relevant. Best Oliver On 31.05.2018 01:24, Waldemar Brodkorb wrote:
