I needed to add:

/* Define (sn)printf formatters for these lwIP types */
#define U16_F "hu"
#define S16_F "hd"
#define X16_F "hx"
#define U32_F "lu"
#define S32_F "ld"
#define X32_F "lx"

to my lwipopts.h. Thanks

When i enable debug LWIP_DEBUG 1 i get no messages. How do i toggle the 
debug level?
