We are trying to install wifi driver for Xradio Xr-819 and also for D-Link Wifi Adapter in Mainline Image of Orange Pi PC. We have tried for xradio by https://www.cnx-software.com/2016/11/10/allwinner-h2-linux-android-sdk-and-allwinner-xr819-wifi-driver-released/ and https://github.com/fifteenhex/xradio. Also, we have tried by installing u-boot https://notsyncing.net/?p=blog&b=2016.orangepi-pc-custom-kernel. We have tried for D-Link by https://github.com/xk/rtl8812AU_rtl8821AU and http://www.philipzucker.com/getting-goddamn-wifi-on-the-goddamn-orange-pi-pc/. Also, we tried to made modifications in file /etc/network/interfaces but that file shows in Read Only Mode but nothing works out. Need help ASAP.

Thanks martinayotte, So I've reflashed my sdcard (fs was corrupted after to many reboot i think) I've disable xradio, lowered cpufreq to 600Mhz, installed ser2net and armbian monitor. Boot was succesfull with usb, soc temp is at 29°C (if sensor is accurate ) I just have to wait some days

Thanks chwe, I doesn't know but that useful. That's going to help me to save lot's of time. Is there a guide to disable xradio ?

My OPiZeroPlus2-H3 take about 9 sec to boot, because we are talking about Armbian image here, not some crappy image taken elsewhere ... OPiZero-H2 has a crappy XRadio WiFi, it sometimes can take longuer to get DHCP address than OPiZeroPlus2-H3 ...

Try blacklisting wireless (xradio) and set lower max CPU frequency (/etc/default/cpufrequtils). Some revisions of this board have overheating issues ... which are a possible cause for troubles. Where does it hang?

@Igor Is there a way to tell the difference between the beta (xradio works) and stable?

@fehernyul The Armbian mainline beta worked fine with wifi using 4.17 kernel. I'm not sure why the xradio stuff was stripped out of the stable release. If you do not have a mini shield then the only way to access the Duo is through the serial port (USB when plugged into PC powers Duo and allows serial access) or build your own Ethernet port. In any event the stable release is worthless for stand alone Duos which most of my usage scenarios require. I was lucky to have 3 mini shields, so I was able to get Ethernet working to play around with configuring wifi. For now I have been using the FriendlyElec image since xradio works fine, but I'd really like to use Armbian again.

Hi All, I have the very same issue with wifi here. I use Nanopi-duo without any additional board and I have no wifi. Currently I can connect to duo via my linux laptop with microusb data cable, nanopi-duo shows up as hanging on /dev/ttyACM3 serial port: sudo minicom -b 115200 -D /dev/ttyACM3 I have exactly the same output like you have for dmesg or "find / -name xradio*, lsmod etcetera. I cannot effectively connect to internet with the board ATM so armbian-config does not work here either. What bugs me I switched from friendlyelec's ubuntucore based linux, where wifi works out of the box! https://drive.google.com/drive/folders/1nRO655LaabJzM-OT7eE7fsPOEDM3PTVg I gave a try to armbian because friendlyelec distro runs with extreme cpu heat on nanopi-duo. Measuring 60-70 C degree, where I can barely touch the heatsink, playing with cpu-freq and governors does not helped. Well armbian runs quite surprisingly cooler, it is 20-25 C degree idle, I can touch the heatsink and it really feels slightly warm. Also under load (stress command) it ramp up a bit to max 50 C then after load ends it drops immediately to range 30 C degree for armbian. We need somehow merge both distro's solution (basically both are the same kernel version 4.14.x and based on ubuntu). Somehow check what friendlyelec distro incorporate that wifi (xradio_wlan) works there out of the box. Also check how armbian distro solved the cpu heat issue so nicely that it is just slightly warm when idling and cools immediately after high load.

@Igor I fixed this by using armbian-config, clearing interfaces and using /etc/network/interfaces. Now I can reboot with a static address. With NanoPi Duo I had to remove netplan and use ifupdown for eth0, but the xradio wifi stuff seems to be missing from the kernel (modules, etc.). But in essence they exhibited the same issue with eth0.

@martinayotte @Igor Both of those sections are in the dtb. I found vcc-wifi: disabling in dmesg, but no xradio stuff. The Duo with beta has xradio dmesg and more files, so it looks like files are missing in Stable release, not just DT problem. Beta: [ 13.746635] xradio_wlan mmc1:0001:1: no mac address provided, using random [ 14.100561] xradio_wlan mmc1:0001:1: missed interrupt [ 14.100717] xradio_wlan mmc1:0001:1: Input buffers: 30 x 1632 bytes [ 14.100724] xradio_wlan mmc1:0001:1: Firmware Label:XR_C01.08.0043 Jun 6 2016 20:41:04 Beta: sudo find / -name xradio* /sys/devices/platform/xradio_pm.0 /sys/bus/platform/devices/xradio_pm.0 /sys/bus/platform/drivers/xradio_pm /sys/bus/platform/drivers/xradio_pm/xradio_pm.0 /sys/bus/sdio/drivers/xradio_wlan /sys/module/mac80211/holders/xradio_wlan /sys/module/xradio_wlan /sys/module/cfg80211/holders/xradio_wlan /lib/modules/4.17.3-sunxi/kernel/drivers/net/wireless/xradio /lib/modules/4.17.3-sunxi/kernel/drivers/net/wireless/xradio/xradio_wlan.ko /proc/irq/104/xradio Stable: /lib/modules/4.14.65-sunxi/kernel/drivers/net/wireless/xradio /lib/modules/4.14.65-sunxi/kernel/drivers/net/wireless/xradio/xradio_wlan.ko

That was the first thing to check. Now next thing to check if the DT is correctly including the xradio node : under the "mmc@1c10000"node, you should have something like : sdio_wifi@1 { reg = <0x1>; compatible = "xradio,xr819"; interrupt-parent = <0xc>; interrupts = <0x6 0xa 0x1>; interrupt-names = "host-wake"; phandle = <0x37>; }; Check also the presence of "wifi_pwrseq" node : wifi_pwrseq { compatible = "mmc-pwrseq-simple"; reset-gpios = <0x2e 0x0 0x7 0x1>; post-power-on-delay-ms = <0xc8>; phandle = <0xf>; }; (Note : the above values are from my OPiZero board, so on your NanoPiDuo it could be a bit different...) Check "dmesg | grep mmc" to see if something went wrong during power up of the wifi. Do you see some with "dmesg | grep -i SDIO" ? Does "cat /proc/device-tree/soc/mmc@1c10000/status" reports "okay" ?

@martinayotte OK, I have static eth0 config working with the Mini Shield and no more dynamically creating adapters on reboot. I still have the original issue of no wifi device. I assume I need to get the XR819 device working. It used to work fine in beta Linux nanopiduo 4.17.3-sunxi #28 SMP Sat Jun 30 21:45:31 UTC 2018 armv7l armv7l armv7l GNU/Linux which has xradio_wlan.

Just bumped this one: Orange Pi Zero, stable version, legacy kernel Trying to insert Realtek WiFi dongle (8188eu in my case). Module cannot load - with this error: Peeked solution on 4pda - http://4pda.ru/forum/lofiversion/index.php?t750921-1740.html - decompiled script bin and set wifi_usbc_id = 1 - before it was set to none. Original solution has value "2", but it was just a guess, so I used "1". Module worked in parallel with original xradio. According to original poster on 4pda, this issue was seen on Orange Pi PC. Not sure, is it correct solution, but, well - it may help. Issues seen - when I try to unload realtek module, then modprobe back with some other parameters for powersaving or mac changing wia rtw_xxx options - original xradio gets also resetted. Issue with wifi_usbc_id does not show up, if i use ralink 2800 dongle for example. Hope it is not a duplicate topic and may help others somehow.

There are only two versions of this driver as you already discovered. One is stock, from Allwinner and the other is a result of a desperate attempt to make it work on a modern kernel. I don't recall any other wireless driver that would waste community that much time. Do some search on the forum to get a picture: xradio, xr819, zero wireless, ... Rather pick 8811AU (or better), plug it into USB and forget that Opi Zero has a wireless chip.

This is what I get after excluding xradio driver from the build.

Probably... But my background is chemistry, or to be a bit more precise I did scale up from small to big.. And things you think about there is: What happens when...? your wifi stuff ends in a locked kernel, kernel panic what ever.. the RT capabilities aren't that good as you though and some stuff which keeps the drone in an automatic flight mode doesn't work properly your FS is somehow corrupted and your SBC is for whatever reason not longer accessible during flight. To penetrate WiFi you have to flight over other peoples home (the legal aspect of your project is another field which I don't answer cause I've no idea what is okay and where it gets problematic) but I'm sure you get a bunch of problems when your drone hits somebody and the legal authorities figured out that this happened cause your drone was in an auto-flight mode with a setup which wasn't appropriate. Legal authorities are a bit picky about drones in those days, and you shouldn't gave them a reason that your drone project to make it harder for the 'good guys' developing fancy and nice stuff for drones. I would use the SBC on your drone only for collecting telemetric data not needed for a proper flight and your WiFi stuff you want achieve and stick to a flight control which is known that it works well. For sure a more conservative approach, but when it comes to fly over other peoples home safety should be adressed first over the other goals of the project. You wan't be one of this guys: https://www.theverge.com/2014/11/13/7205741/i-almost-killed-someone-with-a-drone In terms of performance (for the network penetrating stuff), I think a cheap H3/H5 board will perform similar or even better.. And if you buy one with a decent onboard wifi, you're able to connect external antennas so you might no need a second wifi attached to it. Maybe a BPi m2-zero? the built in wifi (AP6212) is for sure better than the Xradio stuff on OPi0 (the 'original' not OPi0plus etc. they change wifi chips quite often... ) or NanoPi Duo, but the board has no official Armbian support and needs some tweaks to get it boot... Whereas boards with a pmic developed for tablets (e.g. often on A64 boards populated) would make sense cause you'll power your board from battery (but I've no clue how good the software side for such boards is, and which board has a known working battery powered possibility).. btw. the 'new' small beagle (PocketBeagle):

Thank you very much...

Optionally disable onboard wifi - blacklist the module xradio. Then attach a good and supported wireless chip and you are good to go. 881x is a good choice but there are other good as well. You can find them on download page: https://www.armbian.com/orange-pi-zero/ (scroll down)

Very good. The xradio-driver on boards with the xr819-chip seem to work as well with 4.14.17 noe - tested: sunvell r69 and nanopi duo.

@Igor: The source of the error is the XRADIO driver: scripts/Makefile.build:320: recipe for target 'drivers/net/wireless/xradio/ap.o' failed make[4]: *** [drivers/net/wireless/xradio/ap.o] Error 1 scripts/Makefile.build:579: recipe for target 'drivers/net/wireless/xradio' failed make[3]: *** [drivers/net/wireless/xradio] Error 2 make[3]: *** Waiting for unfinished jobs....

Renaming/disabling the xradio patch file is a better option IMO.
