使用CCS5.4烧写2812 FLASH以后，断电重启运行不了，必须连上仿真器才能运行程序，这是为什么
#ifdef FLASH
// Copy time critical code and Flash setup code to RAM
// The RamfuncsLoadStart, RamfuncsLoadEnd, and RamfuncsRunStart
// symbols are created by the linker. Refer to the linker files.
MemCopy(&RamfuncsLoadStart, &RamfuncsLoadEnd, &RamfuncsRunStart);
// Call Flash Initialization to setup flash waitstates
// This function must reside in RAM
InitFlash(); // Call the flash wrapper init function
#endif
。
请问哪里出现了问题
工程有没有什么警告之类的。
CMD程序如下

问题找到了，就是flash掉电运行的时候必须将插在DSP上面的仿真器拔掉，拔USB这端是没有用的。
上面的CMD配置是正确的，flash运行必须把仿真器连DSP那端拔掉，光拔USB是不行。花了我两天时间，结果是这个问题。

这样?我也是插着仿真器烧flash后还是插着呢，没有这个问题啊。
你是什么仿真器，是xds100的那个么?
