仿真时JTAG出错，下进去程序可以用是怎么回事？

我在调试外部中断的时候，当低电平出现就点亮LED，现在发现当我切换到低电平后，Jlink就报如下错误，但是我程序下进去，能正常看到LED灯闪，怎么回事啊

拔了关机重启，再测试

回复【2楼】ST-FAE-SALE:
---------------------------------
还是一样的

你这是仿真遇到的问题吗，还是下载遇到的问题，你是在什么开发环境底下完成的。

回复【4楼】ST-FAE-SALE:
---------------------------------
我在测外部中断，低电平触发，然后开始能进调试界面的，等到我给低电平了就报错了。我的低电平是由交流12v整流滤波电阻分压来的。

那很可能是你的硬件出了故障，才出现的问题，

回复【7楼】ST-FAE-SALE:
---------------------------------
那为何不在调试状态就没问题呢？直接下载运行就没问题

调试的时候，错误数据可以打断仿真。

---------------------------------
我也遇到过同样问题，换块板子就好了，硬件问题，

进来调试LPC1788出现**JLink Warning: CPU did not halt after bootloader的问题，就是不能进入调试与运行模式，但可以用Jlink正常擦写。搞了很久，最后发现P2.10 ISP串口下载使能引脚一直拉低，所以CPU一直处在串口下载模式，导致了无法进入运行于调试模式，把P2.10教拉高问题解决了

我现在也遇到了同样的这个问题,但是我看了半天也没有看懂这个问题最后是怎么解决的.
难道是硬件问题吗?
竟然是硬件问题,那最后又是怎么解决的呢?
能不能详细的说明解释一下?
