I’m the original poster and I’ve been successfully running Armbian 23.1.1 on my Orange Pi 3B v1.1.1 for 60 days.
The image I used is Armbian_23.11.1_Orangepi3b_bookworm_edge_6.6.2.img.xz, which I downloaded from the Armbian archive https://archive.armbian.com/orangepi3b/archive/
$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Armbian 23.11.1 bookworm
Release: 12
Codename: bookworm
I successfully used armbian-config to switch to a 6.6.39 kernel:
$ uname -a
Linux latita 6.6.39-current-rockchip64 #1 SMP PREEMPT Thu Jul 11 10:49:22 UTC 2024 aarch64 GNU/Linux
Thanks to @heyrict and @Igor for their feedback!
Manuel R got a reaction from Igor in Armbian on Orange Pi 3B with Vendor Images (Linux < 6.6) don't seem to work
