求助各位高手

你的问题是用CCS5烧写DSP2812后，DSP没有正常的运行，是指烧写Flash后脱开仿真器重新上电不能正常运行？而挂着仿真器调试正常？

首先感谢您的回复。挂着仿真器SEED510是能够正常调试的，用的是烧写FLASH的CMD文件，然后断电脱开仿真器后重新上电不能正常运行。连接仿真器是可以看到内存空间中FLASH初始化明显在RAM里面：

0x3F9F00 ramfuncs_runstart, InitFlash
0x3F9F00 2538 EC60 E26D E2B6 A347 5895 523A 7BBE CB32
0x3F9F09 B812 742C 2021 75AD 55DC 40B9 AC4E 6D1A A0F1
0x3F9F12 7AAA B838 747B

（1）附CMD文件中的拷贝代码：

ramfuncs: LOAD = FLASHAB, PAGE = 0 /*RAML1*/
RUN = SECURE_RAM, PAGE = 0

RUN_START(_ramfuncs_runstart),

LOAD_START(_ramfuncs_loadstart),
LOAD_END(_ramfuncs_loadend)

（2）主函数中关于memcpy调用

//======内存Flash初始化，调用memcpy=============================//
memcpy(&ramfuncs_runstart,&ramfuncs_loadstart,&ramfuncs_loadend-&ramfuncs_loadstart);
InitFlash();

（2）附源文件列表：

（3）挂仿真器调试后的正常运行的图片

（4）on-chip  FLASh的设置

（5）脱开仿真器，应该FLASH中有程序了，应该能够正常的启动，但是没有运行，串口没有数据出来，所以郁闷了。有几个警告，但是好像是兼容性问题，应该没事。

检查下#pragma CODE_SECTION(InitFlash, "ramfuncs");

您说的这段代码肯定有，不然挂仿真器调试时，看不到FALSH初始化程序在RAM里面。

附FLASH初始化程序：

void InitFlash(void)
{
EALLOW;
//Enable Flash Pipeline mode to improve performance
//of code executed from Flash.
FlashRegs.FOPT.bit.ENPIPE = 1;

// CAUTION
//Minimum waitstates required for the flash operating
//at a given CPU rate must be characterized by TI.
//Refer to the datasheet for the latest information.

//Set the Random Waitstate for the Flash
FlashRegs.FBANKWAIT.bit.RANDWAIT = 3;//最小值

//Set the Paged Waitstate for the Flash
FlashRegs.FBANKWAIT.bit.PAGEWAIT = 3;//最小值

// CAUTION
//Minimum cycles required to move between power states
//at a given CPU rate must be characterized by TI.
//Refer to the datasheet for the latest information.

//For now use the default count

//Set number of cycles to transition from sleep to standby
FlashRegs.FSTDBYWAIT.bit.STDBYWAIT = 0x01FF;

//Set number of cycles to transition from standby to active
FlashRegs.FACTIVEWAIT.bit.ACTIVEWAIT = 0x01FF;
EDIS;
}

如果代码和软件配置各方面没问题，就检查一下硬件，首先是boot mode的那几个脚，测试看看是不是配置成Flash启动模式，其次是复位电路是否正常工作

感谢您的回答，由于之前用CCS3.3和一样的程序烧写成功了，所以应该不会是硬件的问题，此外还换了一个一模一样的电路板试了一下，也不行。

附启动文件，看有没有问题：

（1）启动文件：DSP28_CodeStartBranch.asm

;//
;// TMDX ALPHA RELEASE
;// Intended for product evaluation purposes
;//
;//###########################################################################
;//
;// FILE: DSP28_CodeStartBranch.asm
;//

;// Ver | dd mmm yyyy | Who | Description of changes
;// =====|=============|======|===============================================
;// 0.58| 29 Jun 2002 | L.H. | Original Release
;//###########################################################################

; Typically this section will be used to redirect code execution when using
; the boot mode "jump to Flash". It can also be used for "jump to H0" or
; "jump to OTP" modes.

; In this case, code needs to be re-directed to the C initilization routine
; called _c_int00.

; If code execution should begin at a different location (for example in
; assembly code) then modify the branch to location and .ref statement for
; the new location

.ref _c_int00

.sect "codestart"
LB _c_int00

有仿真器能仿真，脱机不能运行，这个最先检查的，看 GPIO 的 boot 模式设定是否正确；还有就是你的芯片供电是否充足，用示波器测运行中芯片的 3.3V 和 rst 脚。大部分都是这两个问题。我这两种情况都遇到过。
