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,

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,
Ping

Hi Ray,

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

Thanks~~

Best regards

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:
