Armbian already is! uname -a Linux orangepi5-plus 6.15.0-edge-rockchip64 #1 SMP PREEMPT Sun May 25 23:09:23 UTC 2025 aarch64 GNU/Linux Itś on edge, but it's working fine here, apart from the analog audio...

Its 64bit, but support quality (tl;dr;) of Allwinner is behind Rockchip.

Created another standalone version of script for this ... https://gist.github.com/avatar21/e0deca347665bd620d0ea3f9f299028e I believe we need to compile our own armbian/ Kernel 6.13 (or above? because as @elvis claimed user driver is only 1/2 of the equation) before running this script ya? all copy/ flatten to a temp/fake root folder (where I understand the chroot sdcard means, build to a fakeroot not patching existing OS) and repackage as an img file ya? Or better still, can someone compile the whole thing? start from burning image ...

That RK356x would not be much faster than the H618 I think and "sunxi kernel" is 32-bit, I assume you use and mean 64-bit. DKMS always needs attention (in my experience), so I am happy I made/have my computers/boards such that I do not need it. actually, this topic made me do: apt purge dkms -y, as last week dist-upgrade from Bookworm to Trixie/Testing also had some issue (only a warning, not fatal) regarding DKMS. In the past I used it for some SDR hardware module, but for WiFi USB dongles I simply have a red line: If no mainline kernel integrated code, I do not use is. Also what Igor points to, that stick you have is just very low wireless performance. Use RJ45 or buy good WiFi module I would say. zfs-dkms has no hardware/vendor origin, so that is less of a problem, but note that for cheap low end SBC hardware, Btrfs also works fine and is in the Linux kernel so no special care needed. Also works fine on old ARMv6 Raspberry Pi0/1 including Zstd on-the-fly compression etc. You could create an 2-parttiton image (and U-Boot blob will be between partition table and 1st partition). Use Btrfs as rootfs and also install vanilla Debian kernel and GRUB EFI. Tag 1st as 0xEF00 (ESP) type. Then that image can run as Virtual Machine (hardware accelerated) on all ARM64 SoCs and also emulated on fast x86-64 PCs. Run armbian build inside that VM. I did that for 32-bit Allwinner as I have NanoPi-NEOs, don't have 64-bit Allwinner SoCs. So then easier experiementing and developing and you also have kernel log via virtual tty. Still make sure you have real serial cable/console for that H618.

Thanks for your help, and I found the official image not support NPU, only Joshua-Riek image support? @Hqnicolas root@h96-tvbox-3566:~# ls /dev/dri/ by-path card0 card1 renderD128
