    Error with Setting up Ethernet on New Board

    woodworks

      I'm using Yocto image and reflashed from scratch (this is a totally new install). Using the arduino expansion board, a 12v 1A power supply and have serial connected and working. To try to get ethernet working, I attempted Setting up an Ethernet Connection for the Intel® Edison Kit for...

       

      This did not work at ALL on a new board. I have verified wpa_supplicant is working fine and connman was also started without any issues. The adapter works fine on every other computer I have tried it on, including microcontrollers (verified working on Beagle, Pi 2, Pi 3, Arduino). The adapter definitely shows up recognized by `dmesg | tail` and the interface shows up in ifconfig (usb0). The main issue is getting connman to enable ethernet.

       

      connmanctl> enable ethernet
      Error ethernet: Method "SetProperty" with signature "sv" on interface "net.connman.Technology" doesn't exist

       

      As I said before I ran the commands right away on a freshly flashed board. `enable wifi` works but ethernet fails.

          Hello Woodworks,

          Thank you for your interest in Intel products.
          Did you enable the dbus interface in wpa_supplicant?

          Regards,

            Hi Alexandra,

             

            I've run `systemctl start dbus` and `systemctl enable wpa_supplicant` and `systemctl start wpa_supplicant`. Not sure what you mean by enabling the dbus interface in wpa_supplicant--I can try using DBUS to create an access point but the objective is to connect to Ethernet.

             

            Here is the output of `systemctl status dbus`:

              Hi, Priansh

              We are still working to solve this issue.
              Also, I would suggest you to try out a different Ethernet to USB adapter with the board.
