If you have a

, then you should probably be seeking support directly from Keil. ULink's only work with Keil. A Segger J-Trace would be more portable. Doing SWD trace does require the core frequency to be set correctly. There is a

, which seems to work quite nicely. I'm not sure of it's general utility as I tend to instrument my own code.

I'm not sure a ULink-2 is going to get it done, I'm surprised you were able to follow the instructions you cited, as I don't see half the options on the Trace pane.

You can get a regular ULink-2 to do ''PC Sample'', and view the Trace Records. You might be able to drive states in the Logic Analyzer window. I've done SWD on ULink-2/ME and ST-Link V2. My J-Trace is the ARM7/9 model, so no use on the Cortex-Mx
