Problem resolved!
It was a problem in cc.h wich I dont quite
understand really.
Problem occured with LWIP_PLATFORM_DIAG in
LWIP_DEBUGF.
I was given the code so I dont know
on what purpose it was not well write.
Here is what was making all the
trouble.
//Orignial LWIP_PLATFORM_DIAG wich was
doing the error
//#define LWIP_PLATFORM_DIAG( x, ... ) do{ sys_debug( x );} while( 0 ) #define LWIP_PLATFORM_DIAG( x ) sys_debug x -------------------------------------------------- void sys_debug( const char *const fmt, ...
){ printf(fmt); } -------------------------------------------------
------------------------------------------------------------------
What was calling LWIP_PLATFORM_DIAG is
LWIP_DEBUGF
------------------------------------------------------------------
#ifdef LWIP_DEBUG
/** print debug message only if debug message type is enabled... * AND is of correct type AND is at least LWIP_DBG_LEVEL */ #define LWIP_DEBUGF(debug,x) do { \ if ( \ ((debug) & LWIP_DBG_ON) && \ ((debug) & LWIP_DBG_TYPES_ON) && \ ((s16_t)((debug) & LWIP_DBG_MASK_LEVEL) >= LWIP_DBG_MIN_LEVEL)) { \ LWIP_PLATFORM_DIAG(x); \ if ((debug) & LWIP_DBG_HALT) { \ for (;;)\ {\ \ }\ } \ } \ } while(0) #else /* LWIP_DEBUG */
#define LWIP_DEBUGF(debug,x) #endif /* LWIP_DEBUG */ -------------------------------------------------------------
If anyone have an idea on why there was a
bug with the original version.
Im not really good with macro yet and I
wish to learn. Thanks!
