OK...
your signals "seem reasonable"... that is layer-1, lwIP starts at layer-3.
Do you know if your messages actually go out of your hardware ?
Have you tried sniffing with wireshark ?
Above your hardware there is:
Your driver, the layer-2 code, in lwIP terms: "the netif". This has been

Hi Eveyone,
I'm using a Nucleo STM32F767. I have probed all the signals going to the
PHY and they all seem reasonable. I have printf debugging enabled for UDP
and DHCP. For what it is worth I'm connected to a Netgear R7000.
The UDP connected to port 67 looks promising.
I suspect a newbie error
