Hello Chen,

- There are three debug inter faces we can choose for OpenSDA: Segger J-Link OpenSDA, P&E OpenSDA interface, or Mbed interface.  

Please  Drag'n drop or copy and paste the corresponding  OpenSDA Application binary file into the BOOTLOADER drive from your computer file explorer.

About the detail steps please refer to :

OpenSDA Serial and Debug Adapter|NXP      

- Also there is a  summary for debug interface, it is for FRDM-K22, while it is the same with FRDM-K64 .

Summary of FRDM-K22F debug interface

Hope it helps!

 


Have a great day,
TIC

Hi,

1. I recommend you use another PC (it's better Win7) to check whether your board work well,

check the problem is your board or PC.

2. step 5) moving *.bin file to bootloader disk , please send this .bin file to me , I test it on my board.
