Hello Peter Barada,
Sorry in KDS I haven't find the debugger configure file like "init_kinetis.tcl",
so I think we can initlialize the DDR on application code.
There is a guide about "Debugging out of External RAM":
Relocating Code and Data Using the CW GCC Linker File for Kinetis
->7) Debugging out of External RAM

Hope it helps
Have a great day,
TIC
