Where is the download link to this VIM3/VIM3L Ubuntu 20.04 Linux 4.9 V1.0-210112 OTA Release?
or do we download [V0.9-20200530 ] and do full-upgrade?

OTA release is just a firmware update, you have to upgrade via a the
and yes you have to have a minimum version of v200530 …
Hello, in the first post there is an update instruction, it will be enough to execute the command, then reboot, new version! OTA is always put on top, in this case you will always save all your data!
You guys make it way toooo complicated.
Just upload last the images to your firmware page.
New users will start here or use the krescue images.
My experiences so far are that these images are old and should better not be used.
Also tried to download from builds
Actions · khadas/fenix · GitHub but only get 404 not found.

After following this guidance to upgrade Mint desktop based on
Ubuntu-minimal-focal_Linux-4.9, VIM3 continue to auto restart system.
May I need to upgrade U-boot too?
I also faced this issues. so far my only stable image as to update 20200530.
My guess is that this VIM3 need more Power than 5v 2a
February 3, 2021, 12:49am
But I actually power it 5v 3a.

Do not use this image, we don’t provide OTA upgrade for minimal image. Please use
server or gnome desktop images.
February 3, 2021, 1:36am
Thanks, I’ll try gnome desktop.

Another question, what about emmc or SD? Can I upgrade system to v1.0 in emmc?
February 3, 2021, 2:20am
Based on V20200530 release is ok.
Yes but why is V20200530 + full-upgrade working, but all direkt download newer compiled version doing the boot loop?
If it ain’tthe power supply, it a defective v12?
Eg i just tried to install npu as to your guide and when compiling the vim3 will drop network. Or reboot
