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

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);  
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。
