之前debug仿真一直好好的，突然某一次debug就弹出错误，如下：
Error connecting to the target:
(Error -1015 @ 0x0)
Device is not responding to the request. Device may be locked, or the emulator connection may be unreliable. Unlock the device if possible (e.g. use wait in reset mode, and power-cycle the board). If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK).
(Emulation package 5.1.232.0)
用的是SEED XDS510PLUS仿真器，CCS5，TMS320F28335
这是什么原因啊？？求助，感谢～～～
