Timed out waiting for PHY register

[Gnubsch]

Hello,
I have bought three ESP32-POE-ISO boards With two copies the demo for the ethernet interface works. With the third board I get the timeout error.
It has probably something to do with the clock.

I used the ESP32_PoE_Ethernet_Arduino file for this.
Any tips how I can solve the problem?
I have already tried it on different PC's with different USB cables and ports.

Thanks a lot.

Error: Timed out waiting for PHY register 0x2 to have value 0x0007(mask 0xffff). Current value 0x0000[0m

What operating system are you using? What is the baud rate selected?

Edit: It can be driver related.

You used this example, right:

https://github.com/OLIMEX/ESP32-POE/blob/master/SOFTWARE/ARDUINO/ESP32_PoE_Ethernet_Arduino/ESP32_PoE_Ethernet_Arduino.ino

[Gnubsch]

Correct.

[DanKoloff]

When you get the error, what happens if you press the on-board reset button? Does the same error appears?

[Gnubsch]

The error occurs after restarting the device or when I press the hardware button. The same error occurs.

Please drop an e-mail at support@olimex.com with short introduction and link to this GitHub issue, I will tell you how to proceed with the return.

We don't have this problem here and each board's Ethernet is tested empirically so I have no idea what might be wrong. The clock comes from the ESP32, so I don't think it is clock issue.

[Gnubsch]

Thank you for your efforts. I am writing the email to the support.

Hi @Gnubsch, did you get any feedback from Olimex? I'm facing the same problem also.
