In this first integration between Creator 2.0 and Keil uVision, you still need to use miniprog3 as the JTAG debugger. It is planned to have support through other JTAG debuggers like ULink 2 as well.
There is lots of progress we are making with Creator, 3rd party JTAG debuggers are yet to come.
If you are a professional user with Keil uVision, the cost of miniprog3 is not significant @ $89

miniprog 3 is also included in the CY8CKIT-001, which can be used for all PSoC architectures.
