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？
