Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

I referred to the schematic diagram and used these pins. My sdkconfig as:

CONFIG_EXAMPLE_ETH_MDC_GPIO=50
CONFIG_EXAMPLE_ETH_MDIO_GPIO=52
CONFIG_EXAMPLE_ETH_PHY_RST_GPIO=51

but

E (4428) esp.emac.gpio: emac_esp_iomux_init(86): GPIO 50 is already reserved
E (4429) esp.emac.gpio: emac_esp_iomux_rmii_clk_input(196): invalid RMII CLK input GPIO number
E (4440) esp.emac: emac_esp_config_data_interface(611): invalid EMAC RMII clock input GPIO
E (4452) esp.emac: esp_eth_mac_new_esp32(692): config emac interface failed

Hi, the correct pin configuration for using Ethernet should be like this! You can test it, and feel free to raise any other issues if needed.
