Hi abhilash,

Since I have provide a solution for this topic based on IAR, so the CW solution is similar, and even more simple. Please kindly refer to this thread first https://community.freescale.com/thread/308783, and modify the source code as it mentioned.

Then, change the linker file as below:

After compiling, you will have an output map file like that:

before downloading the application, you will have to modify the connection type of the debug configuration, there is a trick for it, you may open another CW project from KINETIS_120MHZ_SC, which contain the connection configuration for DDR debug, in the same workspace. then you may select the proper connection type based on the JTAG type you are using.

OK, with above steps, you may download the image into TWR-K70's DDR2 RAM, and run the application.
