Error when using Ethernet with ESP32

[Sirius]

Hello, recently I downloaded the basic routine of the official Ethernet.
I set the Ethernet in the configuration as the internal Ethernet controller LAN87XX.

On the hardware, we use ESP32 as the main control MCU, LAN8720A chip to control Ethernet, and FC-13ENL as the network port. The software program on another ESP32 chip can be confirmed to run normally, but we encounter the following problems on this ESP32: there are problems with lan87xx: lan87xx_init(299): wrong chip OUI and esp_eth: esp_eth_driver_install(229): init phy failed.

How can we solve this problem?

Do you use some devboard or your custom board?

Do you use some devboard or your custom board? Is PHY address correctly set?
