TI中文支持网C28xx: Error connecting to the target: (Error -516 @ 0x0) The user selected specific frequency failed the scan-path reliability test. The utility or debugger requested the JTAG controller and cable, that generate the JTAG clock, to provide a user selected fixed frequency. The built-in scan-path reliability test has failed. This indicates that the JTAG controller and its cable cannot reliably communicate with the target system at that frequency. (Emulation package 5.1.450.0)
最近使用F28027做无刷电机的控制，但是在使用XDS100 V3（南京研旭出的，USB线带磁环，仿真线小于15cm，带隔离）的仿真器的时候出现问题。
请帮忙看看怎么解决？

Error connecting to the target:(Error -151 @ 0x0)One of the FTDI driver functions used duringthe connect returned bad status or an error.The cause may one or more of: invalid emulator serial number,blank emulator EEPROM, missing FTDI drivers, faulty USB cable.Use the xds100serial command-line utility in the 'common/uscif'folder to verify the emulator can be located.(Emulation package 5.1.450.0)

这个一般是仿真器与芯片匹配问题。你可以换个仿真器比如XDS100V2看看。
