Hi Ram,

   What's the board you are using now? The official board or your own designed new board?

   If your own designed new board, I think you still need to check the hardware.

   You can use the JLINK debugger tool, and use the JLINK commander to connect your board, whether you can find the ARM Cortex M4 core or not?

   If you can't find the core, please input : unlock kinetis

   If the unlock kinetis commander is successfully, then connect the board again, whether it can find the core or not again?

   If you can't unlock your chip and can't find the core,  you need to check the hardware.

   Please check this post, it may useful to you: 

Wish it helps you!

Have a great day,
