OSError: esp_eth_driver_install failed

MicroPython v1.16 on 2021-07-22; ESP32 module with ESP32

Type "help()" for more information.

%Run -c $EDITOR_CONTENT

OSError: esp_eth_set_default_handlers failed (invalid parameter)

How to solve this problem?

HM, it was long time I tried this, it was micropython
1.12 or 1.14 at that time and it was working I have
never seen this error.

currently I have not ready setup connected
esp32 and lan8270 (but I hope to make it soon)

Test with:

ESP ISO POE - Olimex

Compiling microPython with espressif SDK 4.4 for ESP32

Same question...

import machine
import network

machine.reset()
lan = network.LAN(Id=0, mdc=machine.Pin(23), mdio=machine.Pin(18), power=None, phy_type=network.PHY_LAN8720, phy_addr=1)
lan.active(1)

The trick was realizing a machine.reset() is needed to change any of the parameters.
