    failed to modify connection with "nmcli" command, connection is read-only

    in Allwinner sunxi

    Posted

    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

    Boot stuck on Nanopi M1 Plus

    in Allwinner sunxi

    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

    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)

    Hi All,

     

    So after some learning and playing, there are three options that worked for me:

     

    1) use nanopi-air config, use armbian build to patch device tree for uboot, and patch device tree for kernel to add sun8i emac device.  Patch air defconfig to include CONFIG_SUN8i_EMAC = Y.

     

    2) use nanopi-neo config, use armbian build to patch device tree for uboot , and patch device tree for kernel to add mmc device(s). Use Igor's patch above to patch the neo defconfig.

     

    3) write custom board configuration, defconfig, and device trees (uboot and kernel) for a "nanopi-neo-core", patch the kernel device tree makefile and make a custom core image [nanopi-air (+ ethernet) (-wireless)]

     

    Option 3 worked the best for me, and I now have a nanopi neo core image (and build defs) that supports installation (and boot) from eMMC and also has functioning ethernet in uboot and kernel, that I can run from armbian build. Huzzah.

     

     

    I suppose I could push my files from 3) to mainline, but I have never been a contributor (so I don't know the rules) and this goes against the intended plans for the "CORE" Devices. Igor, what are your thoughts?

     

     

     

    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
