I am using FRDM-K64F.
I try to run demo application in debug mode, but it doesn't run and shows following message in console window:

I have seen quite a few articles in which it states.
I don't resolve this trouble.
How can I run my device?
I am using Kinetis Design Studio IDE v2.0 and GDB Open OCD Debugging.
