请教SEED仿真器连接6678开发板的一个问题!!!



用SEED XDS560V2连接我们自制的DSP开发板时出现一个错误,显示如下:

(Error -180 @0x0) The controller has detected a target power loss. The user must turn-on or connect the power supply for the target. (Emulation package 5.0.747.0)

我检查了板卡的上电是没有问题的,请教可能的原因,如何排查问题???谢谢!!!

  • 除了电源,reset信号和时钟输入信号也检查过了吗?还有JTAG信号看一下有没有问题。
  • 遇到过,如果确定电源没问题,那就是复位信号没释放.参考SOC手册,有复位信号的释放时序要求,很可能你的复位根本就没释放.

    如果时钟信号会导致DSP不稳定,链接会掉或仿真混乱,概率性链接不上,多链几次,复位后链接等,是多少可以连上的.
