[lwip-users] DHCP Debugging

[Kenny Koller]

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 of some sort but I feel like I made some effort before posting.

Best regards,

Kenny
