Hi lun wang,

Are you trying to use the USB-KW24D512 as a sniffer? If so, please follow the next steps:

  1. Locate the USB-KW24D512_802.15.4_Sniffer.bin file included in the USB-KW24D512 Board Support Package.
  2. Copy and paste this binary file in the JLink installation path (i.e. "C:\Program Files (x86)\SEGGER\JLink_V600").
  3. Connect the Jlink debugger to the corresponding JTAG connector (J1) in the USB-KW24D512.
  4. Go the JLink installation path, and then open the application "JLink.exe".
  5. Call the next instructions:
    1. unlock kinetis
    2. device mkw24d512xxx5
    3. loadbin USB-KW24D512_802.15.4_Sniffer.bin 0
    4. (select SWD and default speed)
  6. Unplug and plug again the USB-KW24D512.

 

Regards,

Gerardo
