dsp 28377在线升级 实例总结

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

第98行的函数 ：

Example_CallFlashAPI(void)

将数据烧写到地址为0x88000地址为首地址的flash内存当中。并且函数在ramfunc中运行，ramfunc和首地址的跳转在cmd文件中有体现

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);8081 APPEntry = (void (*)(void))(ENTRYADDR);8283 ESTOP0;8485 (*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。
