Hi Venkatesh G,

   What the IDE you are using?

  Actually, you can use the opensda or the JLINK debug firmware, then you don't need to use the openOCD.

  I think you can try the JLINK firmware.

  Please change the JLINK firmware follow this step:

1. Download the JLINK driver from this link:

SEGGER - The Embedded Experts - Downloads 

Then install it at first.

 2. Please download my attached file, and unzip it, you will get 12_OpenSDA_FRDM-KL25Z.bin file.

  1) unplug the KL25 board

  2) press the on board reset button, and hold on it, then plug the USB cable to the PC(win7 system), you will find a BOOTLOADER device, then release the reset button.

  3)Send 12_OpenSDA_FRDM-KL25Z.bin to the BOOTLOADER device, and wait the sending is finished.

  4) unplug the board an plug it again,  you will find your board is the JLINK debugger

3. in the IDE, choose the JLINK interface to download the code.

Wish it helps you!

If you still have question, please let me know!

Have a great day,
Kerry
