Hello Dmitr Shard,
You can try this in .lcf file.
If you create the bareboard project following the wizard in CodeWarrior, you can find there is a .lcf in the folder named 8572DS_RAM_core0.lcf. The file is a way of specifying segment addresses. You could relocate code and data in internal RAM.
See details in Power Arch Build Tools Reference.pdf. The doc is located in the CW installation path:
D:\Freescale\CW_PA_v10.5.1\PA\Help\PDF
See Section 14.8 Relocating Code and Data in Internal RAM.
