WDT activated after LAN init
bug
Port, board and/or hardware
ESP32 - FREENOVE - ESP32-WROVER--DEV
MicroPython version
Test done with MP 1.25.0
Reproduction
- Paste this code in the MP console
import network
lan = network.LAN(mdc=8, mdio=7, phy_type=network.PHY_LAN8720, phy_addr=0,power=None)
Expected behaviour
Expected: To see an ethernet init error since there is no ETH hardware in the device.
Works fine when the ETH hardware is present.
Observed behaviour
MicroPython v1.25.0 on 2025-04-15; Generic ESP32 module with SPIRAM with ESP32
Type "help()" for more information.

Additional Information
i already tried to set the wdt manually with
import machine
wdt = machine.WDT(timeout=1000000)
wdt.feed()
but still the same errors. What else can I try to do?
WLAN and Co is working perfectly in C/C++, and with circuitpy, but i want to use micropython.
Have a nice day!
