I think most of my original problems were related to: Power, Memory, HEAT 1- at one time I made a mistake and was not using the factory power supply 2- the problem with zram and swapping that you fixed for me @NicoD 3- When I first installed it I had not installed fan management, this should come standard.

Pity about the Zram config and pity this is NOT communicated when you download it so you know to run the config, but worse, that it has not been removed or repaired. Yes, when I have 5 minutes, I will duplicate what I did the other day and see what happens. I was trying to test my modified fancontrol.c program so was launching a few you tube videos and facebook pages ;-) Thanks again for your help as always @NicoD Armbian would not be the same without you !

Amazing Nico, this zram info should be on the download page! How did you know that about zram!! Thanks heaps for this and the creating a large swap file!

I've just had a look at this, looks interesting. I won't put it on the M4V2 at the moment as I've had enough problems without adding other potential problems ;-) However, this would be interesting on my odroidN2 which is continually kill boinc processes due to out of memory I was hoping there was another trick on Armbian that would kind of NOT kill stuff but just slow down.. Thanks for your suggestion I'll try it out on the Odroid.

I have a problem with Focal on Nanopi-M4V2 is that when it is overloaded and runs out of memory, instead of getting slow it kills the process causing the problem and in the last few cases, logs out out of Ubuntu Mate ;-) [Sun Jul 26 17:12:54 2020] Out of memory: Killed process 12888 (Web Content) total-vm:3097484kB, anon-rss:455520kB, file-rss:1600kB, shmem-rss:16636kB, UID:1000 pgtables:2752kB oom_score_adj:0 [Sun Jul 26 17:12:54 2020] oom_reaper: reaped process 12888 (Web Content), now anon-rss:0kB, file-rss:0kB, shmem-rss:16220kB [Sun Jul 26 17:13:22 2020] panfrost_gem_shrinker_scan: 60 callbacks suppressed [Sun Jul 26 17:13:22 2020] Purging 4595712 byte This is at the time of running (I was in a tmux session, it was still running when I logged in again) Time big.LITTLE load %cpu %sys %usr %nice %io %irq CPU C.St. 17:12:53: 1800/1512MHz 8.19 98% 73% 23% 0% 1% 0% 65.0°C 0/6 17:12:59: 1800/1512MHz 8.49 67% 45% 20% 0% 0% 0% 60.6°C 0/6 ....

I'd prefer it because slow so that I can investigate what is going on instead of logging me out when I'm testing scrpts or writing scripts or documentation. Thanks in advance.

Thanks very much @piter75 very much appreciated . I'm g'ad this problem is solved,in any case if it happens again , I know what to do. @Lennyz1988 try this out!!!

Thanks NicoD, shouldn't this mess be removed from Downloads then I mean I have Ethernet and WiFi but I need both for when I'm in my other office where I'm not allowed to connect to wired networks. I'm flabbergasted that this kind of thing is in supported Downloads. Regarding /etc/network/interfaces.. This is all NetworkManager. and anyway, the wlan0 device has vanished If you see the message above yours, if I plug in my Wifi Dongle, Wifi works. So I'd like to know how to add the driver to the kernel so it recognizes the onboard wifi...

UPDATE I have plugged in a Wifi Dongle and: iwconfig wlxbcec23c37524 IEEE 802.11AC ESSID:"CoreSoyRocD" Nickname:"<WIFI@REALTEK>" Mode:Managed Frequency:5.56 GHz Access Point: B8:BE:F4:0D:97:F2 .... So if someone can tell me how to get the kernel o recognize the onboard wifi again, all will be fine! @Igor ? @Piotr Czekalski ?

@Werner Thanks for adding to the Wifi Issue AR on Jira !!!

@NicoD How do you get this problem looked at by someone who can advise or fix the problem, this download is in the supported Downloads..

Thanks very much. And this download is in the Supported Download section, quite sad. I wish someone would just advise me about how to recreate it, I think the driver has to be added to the kernel for it to create the wlan interface but I don't know enough about this low level stuff. The worse part is no one from Armbian is really trying to help either.. Double sad. Thanks for your info

I haven't played with very low level stuff, just configured static IPs etc. http://ix.io/2g3E As you can see it existed, but it is gone... Could it be the driver is no longer in the kernel and so it isn't creating the device. But as you can see in my initial message above it existed. If you like, you can log in and have a look. Send me a message and I'll open the firewall and give you a login.. This is much too low level for me. Thanks for answering, if I can't get advice, I'll reinstall it but I loathe to do that as I spent quite a lot of time getting it configured up to here...

Can anyone help me with this problem ?

Hi @NicoD nice to see you and nice to watch the videos, there are 3 I have not seen yet .. I don't know what caused the problems.. After talking to werner I recompiled the fancontrol C program and set it up as a service and I used the original power supply. The rebooting issue disappeared. I think it is stable now but it gave me a lot of problems, I finally changed to SDDM instead of the default and changed to Ubuntu Mate.. Now it works just like I want it to BUT ; In the process I managed to lose my wlan0 device, which I posted about in another post. Yesterday I donated some money to Armbian hoping to help on the support side. And thanks to @Werner who tried his best. Have fun holidaying, I'm not venturing far this year!

I think I have somehow managed to remove my wlan0 interface. I've done a lot of testing on this M4V2 and am happy with my latest configuration and then I noticed my wlan0 interface is gone. I know it was there because I had tested it all (this box is going to my work office I'm not very good with the very low level stuff but this is what I have found sudo nmcli dev status DEVICE TYPE STATE CONNECTION eth0 ethernet connected Nano2Home lo loopback unmanaged -- jerry@nano2:~ $ sudo nmcli con show NAME UUID TYPE DEVICE Nano2Home bfe624a0-6c47-34c7-b947-350dd18b2059 ethernet eth0 Wi-Fi connection 1 62eadfc0-4456-4dc6-8624-771996a69834 wifi -- jerry@nano2:~ $ systemctl status sys-subsystem-net-devices-wlan0.device ● sys-subsystem-net-devices-wlan0.device - /sys/subsystem/net/devices/wlan0 Loaded: loaded Active: inactive (dead) Is it possible to recover from this or do I have to reinstall ? I really appreciate any help..

Wow, thanks very much Werner, the first link is the one I was looking for ... Thanks. And let me thank you for your patience and your help for this strange problem. I'm getting along with the M4V2 very well now, I use Chromium for the sites I know will crash Firefox and for the rest I have one WiFi problem which I'll post about in a new post. Thanks

Thanks @NicoD is touring vlaanderen at the moment, lucky man ;-) BTW, on the main download page for the build I downloaded it says: "SUPPORTED devices are tested and they work apart from known issues and missing features. Support is provided as far as possible (in general there is no support for 3rd party hardware like DVB tuners and software like Kodi). Please check the documentation and existing forum posts before posting a question. Questions on private channels are ignored." So the first thing I did was to ask for the issues page, which no one answered, or you did but you did not try and answer my question, plus, it is the title of this post. So, does this "SUPPORTED" actually mean anything as you're the only one trying to help ?

I downloaded these: Armbian_20.05.4_Nanopim4v2_focal_current_5.4.46.img Armbian_20.05.4_Nanopim4v2_focal_current_5.4.46_desktop.img Tried them both, the reboot stopped after I reinstalled but I have other issues, firefox crashing, Telegram crashing.. I even tried Mate Desktop and sddm. I'm going to go back to bionic with the M4V2, Focal is the worse experience I've had with Armbian since the Tinkerboard!

I'm not monitoring the temperature as I'm busy checking the transfer etc but I could split the screen and armbianmonitor in another screen and see what the temperature is doing. But in that case it means the first thing I need to do is to compile fancontrol and run it but make sure it keeps it cool. And this is not cool!!! I had no problems under Bionic on this system, I just wanted to upgrade to focal. I'm currently running FriendlyElec and facontrol is automatic.

There are no messages, the system simply reboots that is why I wanted to know if there were issues under certain circumstances. No error messages, no panic, no crash, no core dumps, no kernal erros, nothing in the syslog, journalctl shows no additional problems to the ones on installation, just reboots. Copy a directory with hundreds of files over NFS after a while, stops, reboots Copy a directory with hundreds of files using rsync, after a while, stops, reboots All of this on a LAN Another way to reproduce it, Firefox Syncing, I have lots of add ons, Firefox starts to sync, system reboots. Additional software installed tmux, zsh (from armbian SW oh my zsh), vim gtk3, nfs-common, mlocate, firefox, that's about it Using 2.4Ghz Keyboard and mouse.. Nothing much else outside of the ordinary on the h/w side, the box is in the metal case with the fan Configuration SD card and 500GB NVME , the system boots from SD but runs on the NVME - NO EMMC installed That is about it. If anyone has any ideas I'd appreciate it. I'm going to copy IMG to another SD tomorrow and try and reproduce it step by step

Is there an issues page relating to the M4V2 and Armbian Focal. I'm testing it and I have a few strange things happening with NFS and network but I was wondering if there as a known issues or a general topic regarding this board and this Ambian build because searching for nanopi-M4V2 Focal... is not a good idea. Thanks

Since you mention @NicoD may I suggest you look at his other YouTube Videos because he covers installing other desktops , swap files and overclocking on Armbian and MUCH more. He also has a fantastic video about his famous useful commands, you can download is useful commands and learn those, this would give you a huge boost forward in your learning. After watching his videos you can post a comment if some things were not clear to you. https://www.youtube.com/channel/UCpv7NFr0-9AB5xoklh3Snhg This is what I would do if I were you . @Nico

Let us know what you decide, I'd also like to do this and include a NuC in there as well but there isn't a lot of choice.
