ESP32 WROOVER IE LAN8720 Ethernet Connection Problem

[mert200154]

Hello everyone. I am new at IOT and ethernet connections. I made a custom ESP32 board, used chip ESP32 WROOVER IE and for a ethernet connection used a lan8720 ethernet module I checked my schematic all its looks like true and I checked my 50 mHz internal clock from GPIO0 its perfectly gives 50mHz clean signal. My problem is I cant connect any devices with ethernet. My pin configurations completely true. When I uploaded the code I wrote down below its not getting any errors. I can read my lan8720's mac adress but if I dont add my static ip in code IPv4:0.0.0.0 returns at the serial monitor. After that I tried to write static IP in code IPv4:192.168.127.244 shows as I initialized but still cant connect. After all of these when I pressed my BOOT button serial monitor writes ETH Connected when I didnt press the boot button ETH Disconnected occurs. I tested with keep pressed on to boot button and I saw the ETH Connected information came from serial monitor and checked connection, still couldnt connected. I really need help for that. What's am I doing wrong? Also Is arduino IDE version effective?

Is there anyone who can help?

Might be HW issue with your board. Could you please try to debug using https://github.com/espressif/esp-eth-dr ... phy_tester ? Ideally, run the pytest script. However, just note it was tested on Linux so far so you need to be on Linux.

Once you done, let me know the results.
