BTF is hungry for memory, yes. KERNEL_BTF=n and it needs less. On 16Gb+ machine you should be fine. If not memory is eaten away by something else.

https://github.com/armbian/os/pull/426 Once automation finishes - couple of hours, repo will have a missing package. Workaround: manually install package from https://packages.debian.org/forky/zfs-zed

Headers are present. https://imola.armbian.com/apt/pool/main/l/linux-headers-current-rockchip64/ Upgrade packages to latest and try again.

Some context: https://docs.armbian.com/User-Guide_FAQ/#why-things-stop-working The hardest part and expensive for time is keeping functions working while kernel changes, goes up. Image you are referring too is probably a demo image with some ancient kernel that will never be changed. This is usual way to sell hardware. It is made to work, but you will stay at this very old SW stack without any real option to change or fix anything. All functions on 300+ boards, which on top of extreme diversity, have also different revisions, quality issue ... is already not possible to keep up by entire open source community. Armbian is small part focused into SBCs and we do what we can. Work we are doing is never complete, we (nobody) can't solve bugs and especially not near to (expected) real-time. We (or community open source in total) can address a problem within weeks or months fastest as resources are tiny compared to problems that are constantly found in open source code that somebody else made. We have no option to expand the team / project as users don't care about well being of SW developers. We can only try to keep SW stack operational on a best effort principle. Once this job becomes too expensive (<1% of costs share is on users side), we have to step back and declare support as "community". We will continue to build and ship images as they might still work for some use cases and as downstream projects will provide those Armbian images anyway.

Rpi support for whatever of their devices is mainly on the level of RaspberryPi OS. We use their kernels sources as base, add some additional things and release timing is different - not much difference. If they added new device, it should just work. If anyone wants to improve support or fix WiFi -> https://github.com/armbian/build/pulls

There is no way. You need a dedicated image for your hardware. https://docs.armbian.com/User-Guide_FAQ/

Test automation doesn't detect any issues https://github.com/armbian/configng/actions/runs/21465331853 and since I had freshly build Armbian Trixie on Nanopi R6S (same arch) I run install: Works like charm. Make sure to do apt update + apt upgrade before you start.

Did you used most up2date armbian-config? Few days ago some critical bugs were fixed - i tested it several times and it worked ...

Probably, my guess, issue with a boot loader - fail to / disabled by mistake power SATA port? We don't have anyone actively maintaining this kind of (10+years) hardware anymore. Support is "community / upstream" maintained "as is". But this forum / community can provide assistance to fix this. I gave a tip - where I think is the problem. Not working feature on particular hardware is not Armbian problem. This is custom hardware world and our work is tooling https://github.com/armbian/build and best effort hardware maintenance on this principle https://docs.armbian.com/User-Guide_Board-Support-Rules/ If we try to fix everything, everyone would be long burned out ...

Userspace has nothing to do with hardware features. I don't know what is the case for A20, but for many others, OTG functionality is driven with overlays. If there are no overlays, you need to edit device tree and change its role. If that doesn't help, it is more complex problem. More complex, perhaps days / weeks to debug and fix. Most of (Armbian) kernel developers are long gone from this 10+ years old platform and users can't help. Also look into previous builds. Finding out when this broke is half of the solution https://fi.mirror.armbian.de/oldarchive/ or by finding a kernel that works https://docs.armbian.com/User-Guide_Armbian-Config/System/#alternative-kernels With any userspace (trixie/noble/jammy ...) Probably all A10 and A20 boards share this problem.

Feature regressions are sadly something that happens all the time. There are many variants out there and (part of) Armbian OS is different for every board ... First resolve confusion - do you have M1 (we call it just bananapi) or M3. You mention M3 in the text, while title says M1+. Those are totally different boards. Proceed from older images and find out when this feature stopped working: https://fi.mirror.armbian.de/archive/ https://fi.mirror.armbian.de/oldarchive/

Ubuntu Noble variant already supports ZFS on 6.18.y while Trixie was added today: https://github.com/armbian/os/pull/425 Testing: Once automation completes, it will be provided via normal apt update.

Old automated builds are not kept. Only last three releases https://github.com/armbian/community/releases Its 300Gb / week

fixed

It is not recommended to match ZFS with vendor kernel(s). In general. Use mainline based current / edge kernels. Here v6.18.y we also might not have suitable ZFS yet as the kernel is too fresh. But if not today, it will be avail within days / weeks.
