If so that implies that your driver is functioning properly and that you really only need to figure out how to configure DHCP and automatic configuration. If no connections are possible after the manual configuration then the you likely have a driver issue.</div><div class=""><br class=""></div><div class="">I played with both sysvinit and systemd based configurations and it seems the automatic DHCP addressing is handled slightly differently in these environments. </div><div class=""><br class=""></div><div class="">In the case of sysvinit, busybox-udhcpc client is installed and _should_ be bringing your interface up automatically. This worked out-of-the-box for me with no extra config changes needed.</div><div class=""><br class=""></div><div class="">In the case of systemd, there didn’t seem to be a DHCP client configured in the default configuration (for my Beaglebone and Raspberry Pi builds anyway). I manually included the connman package in my build and the interface was automatically configured. It looks like using the networkd PACKAGECONFIG option for the systemd package may be another solution but I had mixed results with that; it may require extra config files in /etc/systemd/networkd or some such but since connman worked for me I stopped investigating.</div><div class=""><br class=""></div><div class="">I’m not sure that’s the best answer and I’d love to hear if there is a cleaner solution for getting a DHCP client in a systemd-based configuration but it may work to at least get you up and running. Of course this solution requires a rebuild of your target image. If your image truly does not have a DHCP client installed then you may have to rebuild.</div><div class=""><br class=""></div><div class="">HTH,</div><div class=""><br class=""></div><div class="">Drew</div><div class=""><br class=""></div><div class=""><div><blockquote type="cite" class=""><div class="">On May 13, 2017, at 5:25 AM, Peter Balazovic <<a href="mailto:balazovic.peter@gmail.com" class="">balazovic.peter@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><div class="">Hello,</div><div class=""><br class=""></div>Unfortunately I have no knowledge about that how image is built :( I got just that image downloaded which is already built. <div class=""><br class=""></div><div class="">BUT after applying <font face="monospace, monospace" class="">ifconfig</font> I got network working and connection established...

Could you please list the commands and steps you used to build the image?<br class="">

Which <a href="http://i.mx/" rel="noreferrer" target="_blank" class="">i.mx</a> board are you using? There are dozens of them.<br class="">
