KL28Z512VLL7 Issues

I have 2 KL28Z for my startup projects, both are KL28Z512VLL7. I'm still very new to this board.


However, I'm facing a few weird issues as below:


Board 1:

My computer can't detect any disk drive after plugged in, the only disk drive that I'm able to detect is the bootloader.


Board 2:

Fortunately the disk drive able to get detected and from device manager it shows up as COM16.


But, I can't connect to the board even using the putty or teraterm terminal. I have set the baud rate to 115200 but still no luck.


Then, I installed KDS 3.2, SDK2.0 KL28Z downloaded from FRDM-KL28Z|Freedom Development Platform|Kinetis MCU|NXP & also JLink V6 etc. I imported hello_world demo project, compile and debug using Jlink. It can't even run and the program already dead when running startup.S file.



Is there anything that I can do? Maybe restore the boards or something else?


Looking forward for reply. I need to proceed & rushing for the deadline. Thanks in advance.
