Hi,
I have a ULINK2 debugger and Core-M3 board. I have a simple program that will print a simple "Hello World". I want this printf output will be display in the Debug (Printf) viewer on my uVision IDE, this will happen during Debugging. I've already setup the Retarget.c for the ITM_SendChar and enable the Port 0 for the ITM Stimulus Port.But unfortunately when I do debugging theirs no display for Debug(printf) viewer and it has a display in the bottom portion of the IDE: Trace: No Synchronization. If I do debugging using SIMULATION i can view the printf output display in Debug(printf) viewer but if I do debugging using the Debugger (ULINK2) theirs no display on the printf viewer. I've read on the "ULINK2 User Guide, Trace Status: No Synchronization --> There are no synchronization packets received from the target. This indicates that the Trace hardware is either not connected or improperly configured.", but I'm still can't figure out how to resolve my issue. Could someone help me....thanks a lot.
