I programmed my code into the KL27Z using KDS3.2.0 and Segger J-Link cable, everything worked fine in debug mode. However, when I removed J-Link connection and power cycled the board, the program did not run. It looks like my program was lost after power was removed. I'm wondering if anybody knows what could possibly the reason?

I used to have the same setup with my previous version of boards and it never failed this way. Now I have the new board with same microcontroller, with a different I/O assignment. I'd appreciate your help very much.

For the record, I'm using the MKL27Z256xxx4.

Thank you.
