adin1110

Hi drollinger 

Thank you for your question.

It may be possible to use two pairs for TX and RX but not recommended. Each line must be properly terminated with 50ohm resistor. We recommend using two wires with suggested circuitry.

I am curios about the ADIN1110 being driven by an nrf52840 USB dongle. 

So, I have hardware that connects the ADIN1110 to the nrf52840 usb dongle by Nordic Semiconductor. I have compiled the secure_mqtt_sensor_actuator given in the Zephyr RTOS project v2.9.0, The merged.hex has been programmed onto my hardware. The USB interface seems to run, but without hooking my host processor into the ADIN1110 specifically and driving the gpio that configures the mac-phy no useful operation can be expected. 

Question: I am seeking some specific information from ADI to port the zephyr ssecure_mqtt_sensor_actcuator sample application to another processor, specifically, the nrf2840, an overlay at a minimum. I am willing to create a documented recipe in case the next developer ask a similar question. It would be similar to the following documented recipe, but updated. Thank you!
