I just tested the code on one of my NR7101s. Started the tool on a host connected to the LAN port of the NR7101:

bjorn@idefix:/tmp$ /tmp/zycast -i eth0.10 -f openwrt-snapshot-r22900-abec62a54268-ramips-mt7621-zyxel_nr7101-initramfs-recovery.bin -t 10
Press Ctrl+C to stop before rebooting target after upgrade
^C
Closing all files

And then I powered on the NR7101. Console output:

Which IP-address must my pc have?

-i eth0.10

My ethernet-device is probably enp1s0. It depends on the pc, which I will use.
