@Igor, thanks again. I used armbian-config to set up the wifi via serial. Do you have an idea when you'll have the dev kernel working? The only reason I'm asking is >= 4.16 allows PWM in user space. Linux nanopiduo 4.14.70-sunxi #240 SMP Mon Sep 17 13:32:31 CEST 2018 armv7l armv7l armv7l GNU/Linux

Cool, thanks @Igor I'll check out the new build tonight when I get home and report results here.

@Igor It worked with beta using 4.17 kernel (Linux nanopiduo 4.17.3-sunxi #28 SMP Sat Jun 30 21:45:31 UTC 2018 armv7l armv7l armv7l GNU/Linux). Don't remember what version it came with or if I updated the kernel.

@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.

@ag123 I'll try that this weekend. There are no nightly images for Duo, but I'll try to update armbian-config over Ethernet connection. The dtb looks like it has the right settings, so it's a matter of getting the modules, etc. that were working in the Beta release. Good thing I bought the mini shield or I wouldn't have Ethernet to do this

I think when I built it for Python/Java stuff I made it use a SO since that's the only way to wrap the C lib.

@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.

It seems the networking in Armbian 5.59 is messed up. It creates a eth0 adapter (disabled) and Wired network 1 adapter. You can delete these in nmtui, but they always return. I had the same issue with NanoPi Duo using mainline Stable. I can get it to work a bit using armbian-config, removing all interfaces and configuring IP, but it get screwed up again. I cannot trust to run 5.59 headless because I have no way to get into the SBC without hooking video back up.

@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.

@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.

OK, I'll start there when I get home.

@martinayotte I have a build VM now, so If there's something I can try build wise to get wifi working I'll try it. I was able to get eth0 working using the Mini Shield, but normally I do not use the Mini Shield. If I try to make eth0 static it creates another wired connection, weird.

I noticed the build tool mentioned Ethernet in the description for Duo. I'm going to fiddle with the kernel options and see what happens, but when I build an image it exhibits the same behavior.

The previous dev mainline release (maybe from a month or two ago) worked with 4.17 kernel. I'm seeing the same issue using the FriendlyElec dtb, so something is off.
