i already have done the setup for the lwip stack on the STM3210C-Eval board. I can already send via TCP/UDP and also RS232 to the uC (PC-->uC) and get also a echo back (uC-->PC). The debug output of the lwip-stack is already configured via cubemx, too. But i have absolutly no idea, how to configure the lwip-stack (via lwipopts.h or something else) that i can see the debug output of the lwip on RS232. Can anybody give a hint ?
Thanks in advance,
