I can't install mpd on Armbian v26.2 rolling for NanoPi Air running Armbian Linux 6.12.76-current-sunxi Packages: Ubuntu stable (noble) user@nanopiair:~$ sudo apt install mpd Reading package lists...

What is the issue with missing packages ?

Continuing to dig into this. Updated the Armbian images - available via the same links above (md5sum mismatch): How to add the module to an already working system (so you don't have to reinstall from scratch): 1. Download the archive ws2801-1.0.tar.gz with the dkms source code for the ws2801 module. 2. Extract the source folder to /usr/src/ : sudo tar -xzvf ~/ws2801-1.0.tar.gz -C /usr/src/ (here ~/ is the /home directory of my user) 3. Install the module step-by-step via dkms: sudo dkms add ws2801/1.0 sudo dkms build ws2801/1.0 sudo dkms install ws2801/1.0 4. To avoid rebooting, you can load the module immediately: sudo modprobe ws2801 By default, Red should start blinking as a "heartbeat" trigger. Description of dts and demo:

A long time ago, that I started the question, but a few days ago, I started again to solve it. And with the help of several AI, I found a working solution. This is the working overlay: /dts-v1/; /plugin/; /* * NanoPI Neo2 H5 - OTG USB with switchable VBUS * Allows SD-Card as USB device on OTG port with GPIO-controlled power * * Key points: * - fragment 0: dr_mode "otg" enables dual-role (host+device detection) * - fragment 1: Removing usb0_id_det-gpios prevents "External vbus detected" error * - fragment 2: Removing gpio property from regulator keeps GPIO 354 (PR2) free for manual control * - fragment 3: GPIO 354 is controlled via usb.sh script (echo 1/0 to /sys/class/gpio/gpio354/value) * * GPIO 354 (PR2) state: * 1 = VBUS ON (USB device recognized) * 0 = VBUS OFF (USB device disconnected) */ / { compatible = "allwinner,sun50i-h5"; fragment@0 { target = <&usb_otg>; __overlay__ { dr_mode = "otg"; status = "okay"; }; }; fragment@1 { target = <&usbphy>; __overlay__ { usb0_id_det-gpios; }; }; fragment@2 { target-path = "/usb0-vbus"; __overlay__ { gpio; status = "okay"; }; }; fragment@3 { target = <&r_pio>; __overlay__ { usb0_vbus_pin: usb0_vbus_pin { pins = "PR2"; function = "gpio_out"; output-high; }; }; }; }; This allows the standard GPIO controls using sysfs in /sys/class/gpio. I'm using the kernel Linux nanopineo2 6.6.75-current-sunxi64 on Armbian 25.11.2 bookworm (32 bit userland). Hope this helps everybody trying to achive the same 😉
