C6678主核不断复位问题

最近在调试一块DSP C6678板卡,上电时序和复位时序都是本人编写,板卡上有4片DSP,其中三片能够正常运行,有一个加载程序就跑飞,电和时钟查了很多遍都没有问题。原本以为是芯片问题,焊接第二块DSP板还是相同位置的DSP不正常。报的错是什么held in reset,硬件上测量并没有复位信号。查看寄存器,local reset始终是1(仿真器链接上一会才会变1,变1后始终不变,无法清除),可我FPGA程序里就没有使能外部的local reset(内部的看门狗也没有使能,只连仿真器不加载程序查看寄存器值也是一样的)。四个DSP的配置都是一样的,硬件电路也是一样的,核0可以运行几步,然后就跑飞,其他核没有问题,能够正常运行。

曾近还报过这样的错:can't run target cpu:(Error -1016 @0x0) Unable to complete execution control command request bacause a breakpoint was encountered before the command was submitted.Acknowledge this halt before continuing.(Emulation packagd 5.0.872.0)然而我并没有设置什么断点。

哪位大神遇到过类似情况?????
