Hello Cengizhan Yapicioglu,
The bare board sample project provided in CodeWarrior is only a simple "Hello World" program running on the board without OS. CodeWarrior doesn't provide TCP/IP stack for bareboard project.
Do you want to design a Linux application project using TCP/IP stack(protocol)? If so, please create Linux application project from File->New->CodeWarrior Linux Project Wizard. You also need to install the Linux Toolchain Service Pack from Help->Install New Software, click drop down list at "Work with" to select "FSL PA Build Tools - http://freescale.com/lgfiles/updates/Eclipse/PA10_5_1/com.freescale.pa.buildtools_win", then click "PA GCC LinuxGNU Build Tools Service Packs" to install this Linux GNU tool chain step by step.
Have a great day,
Yiping
