facing issue in idf 4.4 ethernet basic example.

[kesha.modhia]

- I want to run ethernet in my board
- using esp32 wrover-I chip
- using idf version 4.4
- failing for ethernet basic example given in SDK itself.
- help out here I have attached all the necessary details below,

SET UP

Hi kesha.modhia,

it seems the EMAC is missing RMII REF CLK. Did you enable the oscillator? I think we've already discussed this topic in https://www.esp32.com/viewtopic.php?f=2 ... 8&start=10
