I have the same problem as some other guys here with a ULink2 and a STM3220G-board :
UV4 DB will always display Trace: Running and then 3 seconds latter, Trace: No Synchronization. No data from ITM is displayed.
Are there ay solutions now ?
I set the Max clock down to 100kHz and increased the SWO clock prescaler to 128 - no effect !
I've the same problem. Anybody out there who checks it out?
