core-image-* (minimal) networking

I've built bitbake core-image-minimal and it runs but unfortunately I have
no connectivity (networking) available.

> ifconfig
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:2720 errors:0 dropped:0 overruns:0 frame:0
          TX packets:2720 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1
          RX bytes:206720 (201.8 KiB)  TX bytes:206720 (201.8 KiB)

What's need to be included within local.conf to enable networking?

Install something to do networking. Minimal means minimal.  I tend to
prefer connman as that means you get ethernet hotplug working without
any further work, and you can easily setup wifi too.

Which platform you are working? As you don’t even see the eth in ifconfig, it seems your PHY is not detected, please check your dtb if the required PHY details are added.

Also check your kernel boot log if the PHY is being detected…

 

I believe there is nothing to be added for networking in local.conf. you need to add interface in dtb…

its possible that some modules are missing. Try using core-image-base
and see if that is any better. then we can see what the difference is

Now is up ... and identified and now trying to figure out how to make it
permanent since after reboot I need to do over again.
