使用dsp品台28377d来实现在线升级的功能。
方案 ： 升级程序 + 应用程序
升级程序 ： 主要的目的是将上位机发送过来的应用程序数据（ccs编译生成的.bin文件）烧写到指定位置，之后在跳转到应用程序执行。
应用程序 ： 等待升级的程序

应用程序在调试的时候出现了一个问题 ：
就是在在线调试的过程中，从升级程序跳转到应用程序的时候：
static void (*APPEntry)(void); 80 81 APPEntry = (void (*)(void))(ENTRYADDR); 82 83 ESTOP0; 84 85 (*APPEntry)();
进入应用程序，应用程序总是会在一些地方跳转到异常中断，最后找问题找到是在应用程序中的IntiFlash（）函数，屏蔽掉该函数就正常啦。
IntiFlash（）函数是嵌入到InitSysCtrl（）；中，就是应用程序最开始调用的那个函数。
