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