Having difficulty printing to console in demo HelloWorld.

Hi:

In the Hello World demo I am not able to print to the console. I am using the FRDM-K64F board,KDS_1.1.1,KSDK_1.0.0 with update and Segger OpenSDAv2.

This error message appears: An internal error occurred during: "Semihosting process monitor job. java.lang.IllegalThreadStateException". I have not been able to find

an ansewer anywhere, can someone help?

Hi Ray,

can you clarify what is your console? It looks like semihosting, but not sure? Or is it UART to the K20/OpenSDA?

Maybe this helps:

Hi Ray,

     Could you confirm that there is OpenSDA in your Device Manager?

     Thanks~~

Hi Ray,

I'd like to suggest that you'd better install the OpenSDA driver again.

And I was wondering if you could describe the steps of debug helloworld demo in detail.

I'm looking forward to your reply.
Have a great day,
