I use cube1.3.0 lwip on STM429. It can work and ping ok in release mode.
But in debug mode when I use keil and st-link, it always timeout. I have tried ping and TCP recv/send, it's response 2-3 seconds. Link below say ST demo code has a bug, and should drain the hardware FIFO on each interrupt:http://lists.gnu.org/archive/html/lwip-users/2012-11/msg00013.html
Is it true? How can I clear FIFO ? Thanks in advance.

I enhance the ethenet interrupt priority. It looks better, but still become slow for long time running.
