    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.
    Thanks you, I'll cross post this to my other post

    If you have an NVMe installed anyways you should put the swap there since it is way faster than an eMMC.
    Or investigate if there is a memory leak.

    Hi @JrRockeTer 
    Do :
    sudo apt install zram-config and reboot. 
    That will increase your zram from 1024MB to 2048MB. There's a fault in the armbian zram-config. For 4GB ram it should create 2GB zram. But it by default creates 1GB. 

    If you run on an NVMe, then create a big swap file (don't forget sudo, or use "su" before applying the commands :
     
    fallocate -l 8G /swapfile chmod 600 /swapfile mkswap /swapfile swapon /swapfile echo "/swapfile swap swap defaults 0 0" >> /etc/fstab
    I'll check out Focal mainline now on the M4V2. Cheers.

    Werner reacted to lanefu in Build environment - virtualization   
    right /usr/bin/qemu-arm-static /bin/bash -i requires the `binfmt_misc` kernel module... can you confirm your build vm has that module.

    I literally replicated your issue by not having that module, and then switched to a kernel with that module, and built successful.  Please at least consider investigating the binfmt_misc module

    As am I JR...
    Armbian is such a huge project, with not many people working actively on it. So that's why these things happen. If it were Microsoft we should be p*ssed. But this is Armbian. Free software made for free.

    As I said, for a reliable desktop with the M4V2, this is still the image to go for. https://dl.armbian.com/nanopim4v2/Bionic_legacy_desktop
    There are many other issue's with Focal alone. Then using a mainline kernel with issue's. My bet is it will take about 6 months before that's fully functional. But as said before, I'm no dev. Just a dude trying things out
    Good luck.

    It's not your fault. It's a bug in the latest Focal release.
     
    Yesterday I flashed the latest Focal release available on the website. Everything was working fine until I did a 'sudo apt-get update && sudu apt-get upgrade". After that the kernel updated and my wifi interface was gone.
     
    Buster does not have this bug. So if you are going to reinstall, make sure to flash Buster. Otherwise every time you will run and 'upgrade'  it will destroy your wifi interface.

    That could be an issue. This kind of upgrade is neither tested nor supported. If you have a chance try with a fresh image.
    And always handy to have: armbianmonitor -u

    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!

    Hi guys! Fortunately I found a solution to the problem: Use a gigabit switch. 
     
    Orange Pi 3 and Orange Pi 4 just work on switch with Gigabit technology fine and not with 10/100 interface. Orange Pi One works fine but as exposed in old topic it was fixed. I found after first update many scripts of NetworkManager modified, maybe there are flags and other scripts impacting on NetworkManager.

    Yeah I know, saw the YT videos
     
    Unfortunately there is not much documentation in that case. It is quite hard to keep track what are current issues, what has been solved, what is new and everything across literaly hundred boards...
    Anyway what might be interesting for you is to check JIRA for open threads: https://armbian.atlassian.net/projects/AR/issues/
    I could have mentioned that before.
     
    Support terms are stated here:https://github.com/armbian/build#support
     
    And no, I am no maintainer or developer. I am just a random guy that spends (sometimes too much) time in the forums and help others and collect information that might be useful for actual contributors.
    The issue in general is that the team behind Armbian is way too small for the amount of work and can barely catch up with everything. This of course has some downsides and relying on the community to provide p2p support.

    Hi guys,
    some months ago I implemented an Odroid C2 as readout controller for a scientific instrument.
    Lot of people were kind and helped me with some problems with Armbian, especially eMMC and PWM.
     
    Today, finally, we managed to have our instrument (two strings with several Odroid C2 and other stuff) deployed.
    It is sitting now at 2628m depth in the Pacific Ocean, and will go operational the next days.
     
    Here we are... I think I can announce the deepest Odroid so far (cry loud if I'm wrong :) )
    In the picture you just can see the Titanium housing with two glass covers attached to the string.
     
    Again, thanks for the fish :)
