Port, board and/or hardware

ESP32-POE-ISO Revision L

MicroPython version

MicroPython v1.22.2 on 2024-02-22; Olimex ESP32 ETH with ESP32

Reproduction

lan = network.LAN(mdc=machine.Pin(23), mdio=machine.Pin(18), power=machine.Pin(12),
phy_type=network.PHY_LAN8720, phy_addr=0,
ref_clk=machine.Pin(17), ref_clk_mode=machine.Pin.OUT)
lan.active(True)

Expected behaviour

Expected ethernet to enable

Observed behaviour

OSError: ethernet enable failed

Additional Information

I've pulled the expected working code from https://docs.micropython.org/en/latest/esp32/quickref.html#lan

I know the Ethernet on the device works, when i flash it with a example program from arduino ide, it gets an ip and works correctly.
