这个问题差不多三个星期了一直没有找到原因，望指导！急！

1、首先证明硬件: 烧了一个简单例程到FLASH,然后断电来回起动都OK。

2、在原程序上增加程序内容后，程序会莫明跳到：interrupt void ILLEGAL_ISR(void)这个函数，后来我改了CMD，然后在仿真模式下运行OK。

3、断电起动，程序没有反映，起动不了，在程序初始化增加LED测试，发现仿真情况可以，断电依然起动不了；代码如下：

void main(void)

{

#ifdef _FLASH

memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (Uint32)&RamfuncsLoadSize);

#endif

InitSysCtrl();

#ifdef _FLASH

InitFlash(); // Call the flash wrapper init function

#endif //(FLASH)

//IO配置

GPIO_SetupPinOptions(84, GPIO_OUTPUT, GPIO_PUSHPULL);

GPIO_SetupPinMux(84, GPIO_MUX_CPU1, 0);

GPIO_SetupPinOptions(27, GPIO_OUTPUT, GPIO_PUSHPULL);

GPIO_SetupPinMux(27, GPIO_MUX_CPU1, 0);

for(;;) //infinite loop

{

GPIO_TogglePin(84);//1

DELAY_US(50000);

GPIO_TogglePin(84);//0

GPIO_TogglePin(27);//1

DELAY_US(50000);

}

4、另外一个问题，28377D烧到FLASH很慢，测了一下，大约需要两分多钟。实在受不了

你加载的代码是不是有问题感觉程序跑飞了
看看是否有溢出等还有堆栈等设置大一些试试

堆栈设大一些我都设大了。我是加载到RAM运行点灯程序的，还是不行。

Notes:
Memory blocks on F2837x 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 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 can be combined
if required to create a larger memory block.

请问板子是ti的还是自己设计的呢？
建议对照下datasheet中device boot mode设置，在6.10章节。
另外请尝试使用TI的例程进行修改代码测试。

板子确定没有什么问题。

1、我用例程:\controlSUITE\development_kits\TMDSIDDK_v2.0\IDDK_PM_Servo_F2837x_v2_00_00_00 在FLSH与RAM模式没有任何问题。

2、在这个程序的基础上，加入ECAT代码（较多），在RAM模式下，没有任何问题，在FLASH起动，起动不了。

3、查找原因，带仿真模下，FLASH起动，奇怪的是：带仿真模式下进入后第一次才会进入interrupt void ILLEGAL_ISR(void) 。我复位MCU复位后，后面起动运行都OK。

4、重烧FLASH，带仿真模下，单步，在程序中发现一段：

LocalAxes[AxisCnt].ObjDic = (TOBJECT *) ALLOCMEM(SIZEOF(DefCiA402AxisObjDic));
HMEMCPY(LocalAxes[AxisCnt].ObjDic,&DefCiA402AxisObjDic,SIZEOF(DefCiA402AxisObjDic));

是原因所在，（这段代码是申请内存空间与堆栈，可能是不够用）然后，我加大了 .stack .ebss .econst .esysmem 又发现，DELAY_US（500）这个函数会导致进入interrupt void ILLEGAL_ISR(void)

5、反复修改CMD，就是这个两个问题，导致总是进入interrupt void ILLEGAL_ISR(void)。

希望高手指教，谢了！

请问您的DELAY_US函数有copy到ram运行吗？
正如:\controlSUITE\development_kits\TMDSIDDK_v2.0\IDDK_PM_Servo_F2837x_v2_00_00_00 例程使用IDDK_Servo_2837x_FLASH_lnk_cpu1.cmd文件时对DELAY_US的操作。

公司用TI产品与DSP用量现在都较少，有问题只能自己解决，不能象在广数那样，可以有TI技术支持上门帮助！

回复一下拖了我三个星期都没解决的问题，解决的办法相当粗暴。

其实问题相当简单，controlSUITE的CMD文件只针对他的例程是没有问题的，但如果你加了相当多的程序，他的就不能用啦。

CMD文件里RAM空间都是分段的，以前我没有碰到过这样的情况，但在28377D里，分段存在问题（TI的工程师需要现象找我，哈哈）。解决办法，所有RAM空间定义在一个连续段里，就OK了。当然，要把RMA空间设大，比如：RAMGS0~GS6；28377D有足够的空间！

问题解决了，可以好好睡上一觉！
