You can use ULINK2 to connect the the Cortex-M3. It use the same connector, but will only use the TMS (as SWDIO) and TCK (as SWCLK).
Assume you are using Keil MDK, in the debugger option, you can select if you want to use JTAG or Serial Wire. By switching to Serial Wire Debug protocol, you can then use TDO for trace output (Serial Wire Output), and nTRST and TDI will be unused.
