Ethernet Component compile library error with ESP32-S2 "error: 'esp_eth_mac_new_esp32' was not declared in this scope"

AndySymons commented 6 months ago

The problem

Compiling a config that uses the Ethernet Component with an ESP32-S2 board gives "error: 'esp_eth_mac_new_esp32' was not declared in this scope" Looks like a missing library element?

Which version of ESPHome has the issue?

2024.4.1

What type of installation are you using?

Home Assistant Add-on

Which version of Home Assistant has the issue?

N/a

What platform are you using?

ESP32

Board

WEMOS Lolin S2 Mini

Component causing the issue

ESPHome compiler

Additional information

I also tried board types "esp32-s2-saola-1" (the default) and "micros2", with the same result. I also tried different pin numbers for the mdc and mdio pins, with the same result.

same problem with esp s3 lolin mini. did you ever solve this @AndySymons

AndySymons commented 2 months ago

I cannot fix it because it is a system problem. As far as I know it is still not possible to use the Ethernet component with an ESP32-S2 processor. I had to change the processor in my system to one that is not an S2. The Ethernet component works OK with a WROOM-32D, for example.

For details of all my trials see my project HARVIE Wiki page.
