Now I am learning how to use the debug printf view on the sample "Blinky" project via Keil MDKARM v4.6.0 + uLink2, where my target board is MCB4300 EVB.

I have referred the user guide on ARM website (http://www.keil.com/support/man/docs/ulink2/ulink2_trace_itm_viewer.htm).

However, I met some problem when I did Step 4: ITM Stimulus Port Settings...

I cannot check the trace enable checkbox since it is disabled, either the ITM Stimulus Port 0... (Please see the attached figure)

Does anyone meet the same problem? Teach me please! Thanks a lot!!! :)
