The software needs to program the ethernet MAC with a MAC address.

The software expects to read a nonvolatile memory (flash or EEPROM), obtain the MAC address, and program the ethernet MAC with it.

The example software is prompting you to enter your board serial number so that it can initialize the flash/EEPROM with the MAC address for the first time (because when it already tried to read it, it saw that it wasn't there).

Try entering your board serial number and see if it all starts working.

If it doesn't work (or if it keeps asking you this question every time it starts up), you will need to modify the software to get the MAC address from somewhere else.
