  1. This feature has part of the dtsi upstream since the introduction of sunxi-h3-nanopi.dtsi into mainline in 4.10 - IMHO armbian should not deviate from mainline unnecessarily. An overlay to remove the r_gpio_keys node would be a better alternative for usere wanting to use that button for other purposes.

  2. @sgjava the Duo inherits this feature from this node in sun8i-h3-nanopi.dtsi:

    	r_gpio_keys {
    		compatible = "gpio-keys";
    		input-name = "k1";
    		pinctrl-names = "default";
    		pinctrl-0 = <&sw_r_npi>;
    
    		k1 {
    			label = "k1";
    			linux,code = <KEY_POWER>;
    			gpios = <&r_pio 0 3 GPIO_ACTIVE_LOW>;
    		};
    	};

    You could make an overlay to remove this node using the /delete-node/ or /delete-property/ syntax.

  3. Users wanting to use debian builds with NetworkManager/wpa_supplicant should add the following lines to /etc/NetworkManager/NetworkManager.conf:

    [device]
    wifi.scan-rand-mac-address=no

    Ubuntu builds (bionic, focal) already contain these lines.

     

    This seems to solve the current issue on systems with the xradio wifi chip (opi zero, nanopi duo etc.)
