Hi Tushar Mittal,
I am the engineer who take your case 00144274, we already communicate in this case, so you don't need to follow case 00144275, this is the duplicated case with 00144274.
About the code for TWIKSTICK K40, I suggest you refer to the TWR-K40X256 code:
https://community.nxp.com/servlet/JiveServlet/download/888388-1-401378/KINETIS512_SC.zip
It has the CW project.
If you still have question, please kindly let me know.
Wish it helps you!
Have a great day,
Kerry
