I have no experience with UCOS. Does it work without OS and with# define NO_SYS 1 in lwipopts.h?

No, then I get this:

Maybe I should try 1.32, since the driver is old? Or maybe I should use hello world example with RTOS enabled?
One guy here (afaik) on this thread succeeded running 1.4 or 1.4rc1, so I hope he could help me here. Ofcourse it would be perfect to get an example of working system with uC/OS-II and lwIP, but I still hope to do it myself.
