Not able to connect JLINK debugger to MK64FX512xxx12. Getting error Connecting to target...ERROR: InitTarget(): PCode returned with error code -1

After successfully programming the code, controller works fine. When i again try to load the code, getting error : Connecting to target...ERROR: InitTarget(): PCode returned with error code -1. After resoldering the controller, it connects once more and then give same error. What could possibly be wrong.

Hi Aman,

    Do you secure the chip at the first time program?

   You can use the JLINK command: unlock kinetis

   Then download the code again.

  Please try it on your side.

If you still have question about it, please kindly let me know.

Have a great day,
Kerry
