Ethernet basic example - Error: lan8720_pwrctl: power up failed

[fabiocl]

Hi,

I'm getting the same issue.

However, in order to create a delay between the clock signal and the LAN8720's Reset release, I've included a delay circuit. Similar approach described in: https://hackaday.io/project/85389-wesp3 ... reset-saga

I would like to ask the following:
- Were you able to solve this error?
- Is there any official description or documentation about this Time/delays requirements?
- From the LAN datasheet only a minimum of 25ms is mentioned between the initialization and RESET release.

The delay mentioned above is configured to ~300ms. Is there any max limit (from the ESP32) causing this timeout error? Could you refer where is that in code?

Thank you!
