Just downloaded Armbian_23.5.5_Orangepi5-plus_jammy_legacy_5.10.160.img.xz and installed it to an sdcard to boot up on my Opi5+ and monitored with serial console, but the system wouldn't boot because of a koops. this happened with every boot.
Using the Orangepi5plus_1.0.6_ubuntu_jammy_server_linux5.10.110.img version, I'm able to boot successfully.
I copied the boot files from the OPi5+ img onto my sdcard with Armbian, and made the requisite changes so that the boot environment was pointing to Opi kernel/initrd/dtb, and as expected, was able to boot into the official armbian environment, so i could validate what kernel was installed on the image i downloaded, and it was "linux-image-legacy-rk35xx":
So there's something broken on that build for Opi5+ - at least it's failing on my board.
Happy to provide more info, run test builds, etc.
