HI! I've made a custom board with LAN8720. Generally speaking it's a copy of WT32-ETH01 with a USB added. esp32-lan-i2c-adapter.pdf I'm struggling to get the Ethernet working. Having a weird behaviour: LAN8720 detects link up without cable connected. Here are debug logs I'm getting for ISP-IDF Basic...

Hi morphal, thanks for the interesting post, were you successfull in cutting the IO13 pin of ESP32 module from PHY chip and using it for JTAG? Thanks! Hi! Sorry for late reply but better late than never) Yes, this connection is not used by LAN8720. You can cut it and use IO13 for JTAG. It worked fo...

Hi! Please help me to figure out the ethernet interface implementation of LAN8720 PHY in the ESP-IDF. Specifically my question is about the RXER pin of LAN8720. I have the WT32-ETH01 board. And the ESP32-S1 module's IO13 pin is attached to the RXER pin on LAN8720 with a 10K pull-up resistor. At the ...
