It seems the current image:
did not use /etc/network/interfaces anymore?
I have a small software on the beagle to update this file … it`s now overwriten and the beagle listen on static IP from /etc/network/interfaces and also from dhcp (don´t know from where)
Can You tell more about? Are the IP addresses some normal or IPAPA addresses (169…)?
How looks Your interfaces file (now) ? Sometimes the BBB does weird things…but we need some more info.
With Debian 11.x/12.x images we use systemd-network…
You’ll find configuration files under: /etc/systemd/network/
Thank you.I need ifupdown because of application on BBB.
Did you, if I only have to deinstall systemd-network?
I´m afraid that I kill the ethernet port and lock me out.
