I have a cyclon V board, that works OK with my code.
But on the SD card there is no etc/network/interfaces.d directory or interfaces file.
In etc/network I created a new file called interfaces:
iface lo inet loopback
iface eth0 inet static
But after boot, this file is not executed!
Just when I type:
the new IP address is set.
How can I set this automatically after reboot?
