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...

Did you try the ros support and forums, check here:
