TMS320F28035: InitFlash()程序跑飞

你好，是通过设置断点的方式测出来问题出在InitFlash()吗？还是其他方法？

我看InitFlash()的代码也没什么问题，或者你可以将OTPWAIT设置大一点，但一般只要不是0都可以。

hi green，

1、把断点设置在InitFlash()程序里边中的任何一句话，都会出现以下程序跑飞的提示：

2、但是把断点设置在主程序InitFlash()这里，用单步运行可以进入到程序里边。但是单步运行可以把InitFlash()跑完。

3、把断点1设置在主程序InitFlash()这里，断点2设置在FlashRegs.FOTPWAIT.bit.OTPWAIT = 2包括这句和前边的3句，全速运行都可以停止下来，但是我把断点2设置在FlashRegs.FSTDBYWAIT.bit.STDBYWAIT = 0x01FF这句，出现1中的一样的结果。

4、我把FlashRegs.FOTPWAIT.bit.OTPWAIT = 20，也是出现一样的问题。

会不会是我CMD文件写的不好，导致内存存储出现了问题。用了CLA

我认为这个问题跟cmd文件关系不大，或者你可以试试换一下官方的cmd文件：C:\ti\c2000\C2000Ware_4_01_00_00\device_support\f2803x\common\cmd

有没有修改过系统初始化里面的系统频率之类的？

系统频率配置用的官网的，CMD用了官网的也不行，把以下3句屏蔽了就执行时钟配置，到了initFlash中一样是跑飞。

iRamCheck();

MemCopy(&RamfuncsLoadStart, &RamfuncsLoadEnd, &RamfuncsRunStart);
MemCopy(&Cla1funcsRunStart, &Cla1funcsLoadStart, &Cla1funcsLoadSize);

此外我的代码原来是28033的,我现在在28035上跑的，已经把属性里边+CCXML中都改成了28035,其他的地方没修改，这个原因有没有可能影响？

我认为跟芯片型号关系应该也不大，因为这两款芯片的区别就在flash大小上，其他的memory都是一样的。

我建议你用官方例程测试一下能否正常initFlash，这样可以判断是否是硬件有问题。因为我看了软件上cmd文件、initFlash代码和程序代码都没发现什么问题。如果硬件也没问题的话可能要麻烦你上传一下工程再系统地看一下

hi Green，

     问题已经解决了，在MemCopy程序中用的是大写的Ramfuncs，但是在程序中是是小写的ramfuncs，所以就出问题了。改了就可以进主程序了。

但是用到CLA这部分，拷到RAM里边出现了死循环，一直停在了MemCopy子程序中，我把几个代码贴上来，帮忙看看，谢谢！

1、下边的CLA的拷到ram中，是第1句程序还是第2句？我现在用第一句的时候一直停留在memcopy这个函数中。

2、MemCopy函数是：

3、CLA定义的程序是：

/* Define the memory block start/length for the F28035
PAGE 0 will be used to organize program sections
PAGE 1 will be used to organize data sections

Notes:
Memory blocks on F2803x are uniform (ie same
physical memory) in both PAGE 0 and PAGE 1.
That is the same memory region should not be
defined for both PAGE 0 and PAGE 1.
Doing so will result in corruption of program
and/or data.

L0 memory block is mirrored - that is
it can be accessed in high memory or low memory.
For simplicity only one instance is used in this
linker file.

Contiguous SARAM memory blocks or flash sectors can be
be combined if required to create a larger memory block.
