LWIP Debug Options

[Andrea Picillo]

Hi everybody,

I'm trying to add LWIP to my code but it's not clear to me of LWIP Debug works.

As an example, looking at the code itself I'm able to see the following strings:

if (netif->input(p, netif) != ERR_OK) {
  LWIP_DEBUGF(NETIF_DEBUG, ("ethernetif_input: IP input error\n"));
  pbuf_free(p);
}

I'd like to have the LWIP_DEBUGF printed.

Thank you!
