Thank you for your support, Ondrej.

We have resolved the problem. There was an assembly mistake in the hardware, and we rectified that.

Connect your board to a PC and capture traffic using e.g. Wireshark to see if your board sends DHCP request. I checked the Wireshark log, and there is no DHCP request from ESP. I ran the loopback test mentioned above, but received a failure result. I've attached the log here. What specific aspects ...

I'm working with a custom board designed with reference to the ESP32-Ethernet-Kit, maintaining identical pin mapping and connections to the ESP32 SoC. The only difference is that we are using the ESP32-U4WDH instead of the ESP32-WROVER-E.
