Trace: No synchronizaion with ULINK pro

I have a target system that I am trying to get data out of. I want to use the swo trace output, I can get printf debug out using an ULINK 2 but using the same settings with a ULINK pro I can not get printf debug, just garbage out.

I have tried many settings for core clock but can not find the correct one.

Is there a way to read what the core clock is from the command line?
Is there a way to set it from the command line?

I need it to work with both tools.
