MK20DX128VFM5 resetting continuously

I am using MK20DX128VFM5 in our design for openSDA programming of K66 based on  design. We have fabricated 5 boards out of that 3 boards got programmed successfully and openSDA is working on these. On rest 2 boards, we are not able to program as K20 is resetting again and again. I had browsed for this problem and found in one post that "maybe mk20 is not programmed and watchdog is enabled which is triggering reset pin to get low again and again". I am using keil uVision and need support to troubleshoot this issue. Can anyone please suggest some solution to this problem.
