    Hi Carlos, It appears as if your situation is the lack of the RTOS files and runtime library files. Do you need to have a RTOS in your design? Since you only need the basics UDP, DHCP, etc. this greatly simplifies things, especially not having to deal with RTOS and TCP. I have used the enet_uip project...
