[lwip-users] undef LWIP_DEBUG or PPP_DEBUG the ppp will not work

[RGW]

Hi,

If I define LWIP_DEBUG and PPP_DEBUG on, ppp and debug info works well

#define LWIP_DEBUG

#define PPP_DEBUG                       LWIP_DBG_ON

If I turn off the marco, ppp will not work.

My printf like this:

#define LWIP_PLATFORM_DIAG(message)  printf_safe message

#define LWIP_PLATFORM_ASSERT(x) do {printf_safe("Assertion \"%s\" failed at line %d in %s\n", \

                                     x, __LINE__, __FILE__); while(1);} while(0)

and printf_safe is a wrapper of printf with mutex. 

Thanks,

RGW
