TI中文支持网刚自己做了一块TMS32C5535的板子，因为是第一次接触DSP，调试的时候无法与仿真器通信，错误提示如下。但连接自检是通过的。
test connection 结果：

JTAG电路如下
Shine：
先确认一下target configuration file里是否选择了正确的仿真器驱动和device。

回复 Shine:
没有错，仿真器和device选择是对的

回复 leach yao:
有没有量过JTAG口的信号是否正确？
leach yao：
回复 Shine:
正确的JTAG口信号是怎么样呢
Shine：
回复 leach yao:
EMU0, EMU1高电平，TRST有一个低到高的变化。其他JTAG口管脚的时序见下面的手册第117页。5.7.18.1 JTAG Test_port Electrical Data and Timinghttp://www.ti.com/lit/ds/symlink/tms320c5535.pdf
leach yao：
回复 Shine:
电路测得：EMU0为高电平，EMU1为低电平。
调试仿真时JTAG上的时序如下，然后就报错。
Shine：
回复 leach yao:
EMU1应该也是高电平。
TRST一直是高电平吗？没有低到高的变化吗？
leach yao：
回复 Shine:
TRST有变化的，JTAG通信前有的低到高的变化，通信时都是高电平。TRST平时也都是高电平。
Shine：
回复 leach yao:
EMU1信号检查过没有？应该和EMU0一样是高电平。
leach yao：
回复 Shine:
EMU1一直是低电平
