My NanoPi K1 Plus is using at the moment ARMBIAN 5.47 stable Debian GNU/Linux 9 (stretch) 4.14.51-sunxi64

( https://dl.armbian.com/nanopik1plus/archive/Armbian_5.47_Nanopik1plus_Debian_stretch_next_4.14.51.7z )

 

In the archive at https://dl.armbian.com/nanopik1plus/archive/ is also 

https://dl.armbian.com/nanopik1plus/archive/Armbian_5.53_Nanopik1plus_Debian_stretch_next_4.17.9.7z

 

Is 4.17.9 also stable? And if YES is there a simple way to update without reinstalling?

 

I did try 

apt update

apt upgrade and

apt dist-upgrade

 

but no 4.17.9 avail.

 

Nightly is at https://dl.armbian.com/nanopik1plus/nightly/Armbian_5.46.180622_Nanopik1plus_Debian_stretch_dev_4.17.2.7z

(but I didnt want to switch ti nightly via armbian-config)

 

A stable repository will be upgraded when all supported boards are checked for basic functionality. Switching to beta, update and freeze upgrading perhaps? Is it stable? I have no idea.

Yesterday I adjusted patches that we can build 4.18.y but it crashed exactly on this board on H3 DVFS is missing, Banana/CT Wireless is broken, ... from those impressions I expect quite some work to something stable level. This makes me think:
 

- put 4.14.y back to NEXT, change u-boot to 2018.05 and leave as is even it's not the best option, but people could build it when they needed. 4.18.y is IMO still too far away.

- switch 4.18.y to DEV and slowly work on it.

The last K1 image I built on Aug 15 was: Armbian_5.59_Nanopik1plus_Debian_stretch_next_4.17.14_desktop.img

So far everything I am using is working fine.

Let me know if there is something I can test that will help you.
