TI中文支持网你好，我们现在设计的是一个JTAG链路上挂有两片6678，每次上电后能够找到 16个内核 ，但是 ，过一会 马山就会报如下错误：

你好，感觉你的板卡电压不太正常。查一下上电时序，还有感觉供电不足。

回复 Jacob1:
我们两个DSP能够用仿真器连接，但是只能运行一小会儿，仿真器自动断线，重新连接也能链上，运行一会儿又断线，反复断线也能链上，感觉DSP一直在工作，不能确定是否是仿真器的问题还是板卡问题。

你好，不知道你的问题解决了没有，我的板子也出现了同样的毛病，怎么解决的？ 谢谢

feng gan，您好！
最近也遇到了同样的问题，想请问下，您的问题是如何解决的？是不是和电压不足有关系？非常感谢！
