Helo Simon,
Thank you for referring me to lwip-contrib. I downloaded the version contrib-2.0.1. I found that LWIP_DEBUG is defined as compilation parameters of project layer. I didn't find mention of LWIP_PLATFORM_DIAG. I use LwIP as part of ST CubeMx environment that defines LWIP_PLATFORM_DIAG in cc.h as the following: #define LWIP_PLATFORM_DIAG(message) printf message Can you please advise me how should I direct the "printf message" to serial_write(char *message_string)? Yacob Hassidim.

Instead of sharing yet more ports, why don't you have a look at the example ports for windows or linux in lwip-contrib? There you will find what you are looking for. Simon
