Hi Sunil,
It failed to program the KL26 by using the FRDM-KL26 board, however the FRDM-KL25 did it.
The flow of the thread "Using the Freedom Board as SWD Programmer" definitely is correct, I also did it by following the steps.
So I'd like to suggest that you should check the hardware of the prototype KL26 board at first, and I'm going to share another thread to you.
I think this thread can provide another approach to fix the issue and the link as below.

Have a great day,
