Hello there, I also had the same problem. Tried to set a static IP but it was totally overlooked by the system. When I wanted to look up the configuration, I noticed that the directory '/etc/netplan' doesn't even exist after the system has been installed on the IOT2050. The IP is automaticly DHCP in both ports, even though it was said that P2 would be static and P1 would be dynamic.

How do I enforce a specific IP-Address at startup?

Split from Ubuntu on IOT2050.

Thanks for your reply. Using nmtui does work and it's good to know that there is a grafical interface for a configurations such as this. But how do I enforce a static ip in the build-image-process itself?

Let's say that I want to use the debian or ubuntu image:

https://github.com/siemens/meta-iot2050

https://github.com/siemens/meta-iot2050/tree/jan/ubuntu

Where should I do the configuration? I thought about just using cat to paste some lines like these

auto eth1
iface eth1 inet static
    address 192.168.30.25
    network 192.168.30.0
    netmask 255.255.255.0
    broadcast 192.168.30.255
    gateway 192.168.30.1
    dns-nameservers 208.67.222.222 208.67.220.220

 into the postinst file at 'recipes-core/customizations-example/files/postinst'

I haven't run a build-process with this addon yet as it takes a long time....now trying it out

Any better idea?

Ah, forgot to mention that in this example above the lines would hopefully be appended to /etc/network/interfaces

Yes, that's propably the best option.

I also tried out the nmcli command which is really quite handy.
