UDP - L6218E: Undefined symbol EMAC::get_default_instance()

Hi,

I am trying to use UDP on my custom nrf52 board with this example UDPSocket - API references and tutorials | Mbed OS 6 Documentation

When trying to build this it throws an error L6218E: Undefined symbol EMAC::get_default_instance().

Hello,

maybe because dev board for this target not have any network interface, in the basic configuration.

Thank you. So the only way is to find a board with the same mcu and ethernet module on? Or could I import the library in a different way?

I’m afraid you won’t find a board with this MCU and an Ethernet module under Mbed,
Maybe when you share which module you are using, someone might advise.
