  1. I solved the problem by removing all the references to the wired connection from the "/etc/network/interfaces" file and creating one in NetworkManager. Clearly I set the "managed" parameter to "false" in NetworkManager.conf Regards Marco
  2. Hello, in the company where I work, a nanopi M1 plus was purchased and we are developing a firmware to run on the device. In our code we need to change the settings of the active wired connection at that time, but we can not do it due to an error. If, for example, we use the following command: nmcli connection modify 'Ifupdown (eth0)' ipv4.method auto The following error message is returned. Error: failed to modify connection 'Ifupdown (eth0)': Connection is read-only The command is executed correctly if the connection is not managed by NetworkManager, so when in the file: "NetworkManager.conf" the "managed" parameter is set to false. We had to set it to true because otherwise, by changing the ethernet cable and inserting another of another subnet, we realized that the device keeps the old IP address and therefore is unreachable. So how could we solve that problem? Regards Marco
  3. Hello, I installed Armbian on Nanopi M1 Plus. I used it for a couple of days but now I encountered a problem: the boot stops after the following writing appears: "started hostname service" I tried to wait several minutes but nothing happens anymore Best regards Marco UPDATE: The problem occurs when the device is powered only by the Debug UART, probably the pc usb is not enough to power it
  4. Hi Projetoarduino, I have a problem with your patch. I downloaded Armbian version based on Debian Stretch for Nanopi Neo, then I started the system and I downloaded sun8i-h3-nanopi-neo.dtb file. Then I used this command: cp sun8i-h3-nanopi-neo.dtb /boot/dtb-4.14.14-sunxi/ Then i rebooted system but now it does not load anymore. Output is: (consider that there is another system in emmc and I want overwrite it) Device NOT ready Request Sense returned 00 00 00 2 USB Device(s) found scanning usb for storage devices... 0 Storage Device(s) found Autoboot in 1 seconds, press <Space> to stop switch to partitions #0, OK mmc0 is current device Scanning mmc 0:1...

  5. Thank you projetoarduino. I saw a script called "gen_mac.sh". is it enough that I launch it only once after replacing the file "sun8i-h3-nanopi-neo.dtb"? Marco
  6. Hello, I would be interested in the linux image for the Nanopi NEO Core, or understand what are the steps necessary to create it (I'm not very familiar with embedded linux or kernel recompiling). Regards Marco
