Cortex M3 ITM trace

Do I miss something or there is no way to implement interrupt driven debug trace on Cortex M3?

I know that the SWO interface is relatively fast, but still I would prefer to avoid any polling and blocking...

    Are you referring to ITM text message output feature? which development tool are you using?
    If you are using ULINK-Pro, you can have a very high trace bandwidth and that should help reduce the blocking.
    (I think you can do the same with JtagJet-Trace, which is also supported by Keil MDK-ARM).
