Using Ethernet with the OLIMEX ESP32-PoE-ISO Rev.D

[colomonoir]

Issue template

I am trying to get the OLIMEX ESP32-PoE-ISO Rev.D to work via Ethernet.
The board has a LAN8710A-EZC(QFN32) PHY. I assumed selecting the LAN8720 in the menuconfig wouldn't be problematic.
However this PHY doesn't have the reset (NRST) mapped on any gpio:

I saw that some people use directly the power pin mapped on gpio 12 to reboot the PHY.

That's what I tried with no success, here's the log of idf.py monitor:

Do you have any suggestion on how to get it working?
Is Ethernet transport not supported with this board?

For anyone wondering, you have to set the phy reset as -1, then in Ethernet config set Output RMII clock from internal as true.
Also add these lines in uros_ethernet_netif.c

#define PHY_POWER 12

gpio_pad_select_gpio(PIN_PHY_POWER);
gpio_set_direction(PIN_PHY_POWER,GPIO_MODE_OUTPUT);
gpio_set_level(PIN_PHY_POWER, 1);
vTaskDelay(pdMS_TO_TICKS(10));

after the line
phy_config.reset_gpio_num = CONFIG_MICRO_ROS_ETH_PHY_RST_GPIO;
