TI中文支持网平台：28335，仿真器是SEED-XDS560V2
端午节前出现问题 ：调试时连显示如下错误，试了很多办法不能恢复
Error connecting to the target:
(Error -1156 @ 0x800)
Device may be operating in low-power mode. Do you want to bring it out of this mode?
(Emulation package 5.0.747.0)
1. 检查了电源；
2. 检查了时钟；
3. 检查了JTAG信号；
4. 也试了网友的办法，将boot mode切到 SCI-A后再去联接；还是不行；

CLKOUT引脚上有时钟输出吗
有人推荐的文档 不知道能不能帮助此问题

clkout 有时钟；
手里有三个板子，发现都被我连了一下程序就不行了！
好好回想了下：新的代码，编译完发现太大了就换了一个CMD文件：系统自带的（F28335.cmd+DSP2833x_Headers_nonBIOS.cmd）；未作修改，点的：debug
中间看到过一个erase flash的过程。。。。。。会不会是这个引起的？？？
锁死了吗？？？

分别对现个文件进行了比较：只有F28335.cmd文件有差别，差别部分有红色标注：这里会有影响吗？和同事讨论，应该不会有影 响的啊
