JTAG的问题

用JTAG  download MSP430F2132 的程序的时候，显示错误Fatal error：Could not find device(or device not supported) Session aborted!
可是TDO, TDI, TMS, TCK我都有连上啊，看了下SPEC，说有TEST/SBWTCK: Selects test mode for JTAG pins on Port1. The device protection fuse is connected to test.
请问这个TEST PIN是不是也要接高或者接地么？
而P1.4/SMCLK/TCK的描述是：General-purpose digital I/O
                                                SMCLK signal output
                                                Test Clock input for device programming and test
感觉P1.4/SMCLK/TCK这PIN又不像是JTAG 的TCK了！
