Hi Konstantin, In regards to the page not showing instructions, please copy and paste the full links listed below. If you note within the screenshot you posted, you have the URL of:
"https://kb.ettus.com/Ettus_USRP_E300_Embedded_Family_Hardware_Resource"; The full address is: "https://kb.ettus.com/Ettus_USRP_E300_Embedded_Family_Hardware_Resources#SD_Card_Images"; In regards to the permission denied prompt that is being given in your terminal screenshot -- This is because the command that you are issuing "/etc/network/interfaces" is not valid. When you issue a command that is the path to a file such as that, the system is attempting to pass the file and execute it via the default shell (/bin/sh). I suspect you're attempting to edit the file, which can be done with the utility "vi", such as "vi /etc/network/interfaces". I would suggest starting with a fresh "release-4" image for the E310 at this point. You will need to download the .xz file of the release image for the speed grade of your device (details are in the link below for which SG you need based on the serial number), and then decompress it with a 7z (7zip) or other similar tool. You will then need to burn the image to the SD card, which can be done with WinDisk32Imager or the Linux utility "dd", or "bmaptool". The default setting for the "release-4" image will give the E310 a static IP address of 192.168.10.2. If you then put your VM NIC Settings into a Bridged Mode, and set a static IP Address within the VM to "192.168.1.3", you should be able to connect to the E310 with the root account and no password via SSH. https://kb.ettus.com/Ettus_USRP_E300_Embedded_Family_Getting_Started_Guides#Serial_Console_Connectivity http://files.ettus.com/e3xx_images/ https://kb.ettus.com/Ettus_USRP_E300_Embedded_Family_Hardware_Resources#SD_Card_Images Regards, Nate Temple > On Aug 4, 2017, at 9:29 AM, Matheou, Konstantin J.
