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?
