My board is connected to ethernet hub , and other PCs are connected to this hub , too .
The lwip will die when other PCs access the network (like ftp , http . Not access this board , just access internet ).
But lwip will not die when it connected to layer 2 switch .
My board is STR910-EVAL , FreeRTOS 4.2.1 , lwIP 1.2.0 .
Does anyone have the same problem ?
