@RKroells Which one firmware you use ?
Ubuntu V20200530 + full-upgrade … did manage to get and other the other newer images to run stable 
I don’t understand the meaning of this …
I’d rather get the NPU to work , but your 2 guides dont work.
So please provide more informations. What image you used??
Upgrade guidance:
Based on image V0.9-20200530 9.
khadas@Khadas:~$ sudo apt update
khadas@Khadas:~$ sudo apt full-upgrade
khadas@Khadas:~$ sync
khadas@Khadas:~$ sudo reboot
After upgrade please provide cat /etc/fenix-release & uname -a output.
[16:42:39] root@Khadas:/# cat /etc/fenix-release & uname -a
[1] 42024
cat: /etc/fenix-release: No such file or directory
Linux Khadas 4.9.241 #6 SMP PREEMPT Tue Jan 19 10:16:23 CST 2021 aarch64 aarch64 aarch64 GNU/Linux
[1]+ Exit 1 cat /etc/fenix-release

@RKroells If you use offical firmware , this file /etc/fenix-release must exist, this is one of the files we use to judge whether the version and update are successful
@ Frank,
Im extremely sorry, but this is simple not true in my case.
Ubuntu V20200530 + full-upgrade - https://dl.khadas.com/Firmware/VIM3/Ubuntu/EMMC/VIM3_Ubuntu-server-focal_Linux-4.9_arm64_EMMC_V0.9-20200530.7z
Ive now flashed your only stable working image multipletimes and it has no /etc/fenix- release folder. Either the download images i got is bad or something is wrong with the hardware… Basically I’m out of ideas.
It is /etc/fenix-release NOT /etc/fenix- release.
It has nothing to do with the hardware. You must did something not correct.
Listen
all i do is download your the Ubuntu V20200530 image fron your official website.
This gets flashed via your usb tool.
Then i boot device and do
apt update && apt full-upgrade
Then i reboot and then check for this nonexistent folder
/etc/fenix-release
@RKroells It’s a text file , not a folder

I don’t know why , I can found it everytime after I reburn the firmware
Maybe you can reburn a firwamre ? I see you have installed a lot of other software, maybe these software deleted this file
I managed to finally get a newer Fenix image to run STABLE
.
I always got bootloop once i did apt-full-upgrade
This bootloop stopped once i disabled UBUNTU Watchdog which I find extremely worrying.
This image has the /etc/fenix-release
