Hi,
I Just bought the ESP32-PoE_ISO and I am trying to get it to work with "micro-ROS" an esp-idf components. In order to use Ethernet I have to configure the reset pin of the PHY, however the NRST isn't mapped on any GPIO. I tried to use the PHY_PWR mapped on GPIO 12 instead with no success.
Does anyone have an idea on how to proceed? Would there be a way to set a GPIO for the NRST?

NRSET is pulled up high through 10k resistor R25.

I tried welding a cable from a GPIO to the node before the resistor R25.
Still the reset won't work when the GPIO is pulled low.
I'm not sure why...
