Getting started with K64F - Unable to debug demo app

[willhuang]

Hello,

I'm attempting to get a demo application running (hello world) for the Freedom-K64F board. I've been following the Getting Started guide (FRDM-K64F Platform|Freedom Development Board|Kinetis® MCUs|NXP ) and am currently at step 3 (Build, Run).

I'm clicking on the Debug button in the Quick Start panel, selected the "MBED CMSIS_DAP" probe :

And clicked OK. However, I am getting the following error messages:

Error in final launch sequence
Error: Read timed out
LinkServer has been terminated and will be restarted.
Please restart your debug session.
If the problem recurs, please power cycle your debug probe and restart MCUXpresso IDE.
Error: Read timed out
LinkServer has been terminated and will be restarted.
Please restart your debug session.
If the problem recurs, please power cycle your debug probe and restart MCUXpresso IDE.

I've restarted the IDE, power cycled the board, restarted the computer. Uninstall and reinstalled the drivers and the problem still persists.

Any idea what is going on here?

Hello William Huang ,

What about your PC system ?

- If win7, I suggest you directly change the OpenSDA firmware , to J-link or P&E:

1)Press the Reset button (and keep it pressed) while power the board with the OpenSDA USB connector(J26):.
2)  The board will show up as BOOTLOADER drive on your system:
3) Copy" 02_OpenSDA_FRDM-K64F.bin "(I attached it for you) to the BOOTLOADER driver:
4) The copy operation takes about 2-3 seconds, after finished , unpower  the board.
5) Power the board again normally .

- If win8 or Win10,  first you need to update bootloader of board, then  change firmware , detail

steps please refer to below thread:

Hope it helps.

Have a great day,
TIC
