Hello, Entering SW-DP mode can be done by following instructions in RM0351 chapter 44.3.1. External TCK/TMS sequence is required.

 

Is there any other way to change from JTAG-DP to SW-DP? With ARM Cortex-M3 this can be done as described in RM0008 chapter 9.4.2 AF remap and debug I/O configuration register (AFIO_MAPR)
