  1. Hello I'm quite new with armbian and Banana Pi, but have some experience with Raspberry PI. I started with Banana PI M2 Zero and armbian because of current unavailibility of Raspberry PI which is needed for some of my DIY pinball projects https://lisy.dev/ With a 5.15.48 Kernel Image I noted that the internal ethernet of M2 Zero is set to disabled, where with a 5.10.60 Kernel from the archive it works. After some investigation I used the "sun8i-h2-plus-bananapi-m2-zero.dtb" overlay from the 5.10 Kernel with a 5.15.43 Kernel and was happy that eth0 was working again. However as I think it is not advisable to mixing Kernel versions I wrote an user overlay which can activate eth0 on newer kernels (see code below) questions to the experts: - is my overlay code correct? - is an user overlay the right method to activate eth0? - if both answers to these questions is yes, is it worth to include that overlay to the armbian source and how to do that? thanks for your help /dts-v1/; /plugin/; / { model = "Banana Pi BPI-M2-Zero"; compatible = "sinovoip,bpi-m2-zero\0allwinner,sun8i-h2-plus"; /* * enable onboard eth0 on Banana PI M2 zero * which is disabled by default * bontango 08.2022 * * compile with * dtc -I dts -O dtb -o m2-zero-eth0.dtbo m2-zero-eth0.dts * move m2-zero-eth0.dtbo to /boot/overlay-user * add line "user-overlays=m2-zero-eth0" to /boot/armbianEnv.txt */ fragment@0 { target-path = "/aliases"; __overlay__ { ethernet0 = "/soc/ethernet@1c30000"; }; }; fragment@1 { target = <&emac>; __overlay__ { status = "okay"; phy-handle = <&int_mii_phy>; phy-mode = "mii"; allwinner,leds-active-low; }; }; };
