I have a NanoPi R5S and have flashed rk3568-eflasher-friendlywrt-22.03-20221123.img.gz. When the system comes up, I try to connect from a laptop on the 192.168.2.0 network, but can't see the configuration screens. Logging in directly to the device via keyboard and screen, I can run "ip a", but I see that none of the three Ethernet ports have addresses. When I plug the Ethernet cable in from the laptop, the interface comes up, but still without an address.

How can I solve this?
