2812往Flash里固化时添加哪个库，可以更改么

使用rts2800_ml.lib也可以往flash里烧写程序，您在使用rts2800_ml.lib烧写程序到flash时出现的是什么问题？

显示烧写成功 但是重新上电后并不运行 步骤和使用rts2800n.lib的一样，但是只有使用rts2800n.lib上电后能运行

把你的FFTFLASH.cmd文件发过来看一下吧

您好，请将源文件“DSP281x_CodeStartBranch.asm”添加到工程中，并且在CMD文件的section部分添加语句“codestart           : > BEGIN       PAGE = 0”。

烧完以后Flash锁住了

添加的.asm文件

具体是什么情况？编译工程的时候有没有把“DSP281x_CSMPasswords.asm”添加到工程中去，在操作flash programmer有没有改变密码区的值？除了这两种情况，在烧写的时候电源不稳定也会导致flash被锁。

只加了这个文件

查内存3f7ff8到3f7fff全是0

如果芯片被锁，所有地址都会显示为0。试试这种方法：  Try holding the processor in reset state (if you have a "reset" button for example) while you are connecting to it with the JTAG. After you have been connected, leave the "reset" button and program the flash as general。

现在解锁了，要改哪里下次不会锁呢

最后是怎么解锁的？通常不修改CSMPasswords.asm里的密码，保持全为F就不会被锁。建议使用CCSV5看是否还会被锁。

好像还是和库有关系

一运行就写入数据了

这还是CMD文件的问题，试试用我附件中发过去的CMD文件。

是不是加了DSP281x_CSMPasswords.asm这个文件，仿真的时候view memory里都是FFFF，不加的话就全是0，哪个对

加了DSP281x_CSMPasswords.asm的话，密码区的密码就和DSP281x_CSMPasswords.asm中的密码一样，不加的话就默认是全F。换了CMD文件后是否还有问题？

烧进去程序不运行

cmd文件里有把flash里的载入到ram里运行，我参照官网的例程改了，还加了DSP281x_Headers_nonBIOS.cmd这个文件

	{
	   Flag=1;  }
	if (Count<=0)//循环

}

在程序中再添加一句#pragma CODE_SECTION(InitFlash, "ramfuncs");

好了 谢谢你，如果我把整个程序都放到RAM里运行，是不是把所有的函数

#pragma CODE_SECTION(Ifunctionname, "ramfuncs");就可以了

把程序放到RAM中的是函数MemCopy，#pragma CODE_SECTION用于把指定的函数分配到指定段。先将要放到ram运行的程序分配到某一段，然后再将该段内容copy到ram中，最后再运行copy到ram的某一个函数。

我把自己写的函数都加载到RAM里运行没问题吧

#include "DSP28_Device.h"
#include "fft.h"
#include "math.h"
#pragma CODE_SECTION(fft_init, "ramfuncs");
#pragma CODE_SECTION(fft_subroutine, "ramfuncs");
#pragma CODE_SECTION(Print_Str, "ramfuncs");
#pragma CODE_SECTION(Uarta_PutChar, "ramfuncs");
#pragma CODE_SECTION(send_message, "ramfuncs");
#pragma CODE_SECTION(usart_receive, "ramfuncs");
#pragma CODE_SECTION(wave_judge, "ramfuncs");
#pragma CODE_SECTION(wave_choose, "ramfuncs");
#pragma CODE_SECTION(warn_test, "ramfuncs");
#pragma CODE_SECTION(wave_send, "ramfuncs");
#pragma CODE_SECTION(ad, "ramfuncs");
#pragma CODE_SECTION(scia_receive, "ramfuncs");
#pragma CODE_SECTION(eva_timer1_isr, "ramfuncs");
#pragma CODE_SECTION(eva_timer2_isr, "ramfuncs");
#pragma CODE_SECTION(evb_timer3_isr, "ramfuncs");
#pragma CODE_SECTION(ISRTimer0, "ramfuncs");

没有问题，不过需要在MemCopy调用了之后再调用这些函数，这些函数才能真正的在RAM里运行。

烧写的时候出现这个，是不是说明我还有函数没有放到RAM里，有没有例程可以把整个程序放到RAM里运行，现在的实验现象和在线RAM调试有点区别，我想是不是速度不够，因为用到了FFT

从信息提示来看，好像要需要将某一部分数据也搬移到RAM中。如果程序不是太大的话，也可以将整个程序都搬移到RAM中，可以通过MemCopy .text段实现，具体操作方法请参考以下内容：http://www.ti.com/mcu/docs/litabsmultiplefilelist.tsp?sectionId=96&tabId=1502&literatureNumber=spraau8&docCategoryId=1&familyId=4 。

我原来在RAM里调试的时候CMD文件做了修改，添加了下面自己定义分配的段都是在RAM里，现在是把它们都放到FLASH里搬移还是和原来的一样就放在RAM里就可以

MEMORY
{
PAGE 0 :      
   ZONE2      : origin = 0x080000, length = 0x03ffff 
         
PAGE 1 : 
   /* .....          */     
   
   DRAMH0     : origin = 0x3f9800, length = 0x000700  
   ZONE2ipcb  : origin = 0x080000, length = 0x001FFF
   ZONE2mag   : origin = 0x082000, length = 0x001FFF
   ZONE2tf    : origin = 0x084000, length = 0x001FFF   
   ZONE2      : origin = 0x0C0000, length = 0x03ffff  
}
 
 
SECTIONS
{
   /*......*/

   FFTipcb1  ALIGN(2048)   : {}   >  ZONE2ipcb   PAGE=1
   FFTipcb2  ALIGN(2048)   : {}   >  ZONE2ipcb   PAGE=1
   FFTipcb3  ALIGN(256)   : {}   >  DRAMH0   PAGE=1
   FFTipcb4  ALIGN(256)   : {}   >  DRAMH0   PAGE=1
   FFTmag                 :  >  DRAMH0    PAGE=1
   FFTtf                  :  >  ZONE2tf     PAGE=1

}

需要先分配到flash中，然后再搬移到ram中，分配到RAM中掉电易失。

官网的例程编译出现警告，前两个是这些段没用到吧，后一个是怎么回事，起始地址改变了？单纯烧FLASH和搬移的例程里，一个添加的是DSP281x_CodeStartBranch.asm一个是DSP28xxx_CodeStartBranch.asm,两个里面codestart的地方是不一样的，是这个原因么，还是我的CCS没配置对还是下的例程有问题

那是不是还需要要修改一些asm文件，和配置.cinit一样，它的_cinit_loadstart，_cinit_runstart，_cinit_size都在汇编文件里。

.cinit   : LOAD = FLASH_AB, PAGE = 0 /* Load section to Flash */
                  RUN = RAM_H0,    PAGE = 0    /* Run section from RAM */
                  LOAD_START(_cinit_loadstart),
                  RUN_START(_cinit_runstart),
      SIZE(_cinit_size)

 RAMCMD：

FFTipcb3  ALIGN(256)   : {}   >  RAM_H0   PAGE=1
   FFTipcb4  ALIGN(256)   : {}   >  RAM_H0   PAGE=1
   FFTmag                 :  >  RAM_H0    PAGE=1
 

FFTipcb3  ALIGN(256)   : {}  LOAD = FLASH_AB, PAGE = 0 /* Load section to Flash */
                  RUN = RAM_H0,    PAGE = 0    /* Run section from RAM */
                  LOAD_START(_fftipcb3_loadstart),
                  RUN_START(_ftipcb3_runstart),
      SIZE(_ftipcb3_size)

FFTipcb4 ALIGN(256)   : {}  LOAD = FLASH_AB, PAGE = 0 /* Load section to Flash */
                  RUN = RAM_H0,    PAGE = 0    /* Run section from RAM */
                  LOAD_START(_fftipcb4_loadstart),
                  RUN_START(_ftipcb4_runstart),
      SIZE(_ftipcb4_size)

   FFTmag                 :  LOAD = FLASH_AB, PAGE = 0 /* Load section to Flash */
                  RUN = RAM_H0,    PAGE = 0    /* Run section from RAM */
                  LOAD_START(_fftmag_loadstart),
                  RUN_START(_fftmag_runstart),
      SIZE(_fftmag_size)

DSP28xxx_SectionCopy_nonBIOS.asm里添加

.global _fftipcb3_loadstart, _fftipcb3runstart, _pfftipcb3_size
 .global _sfftipcb4loadstart, _fftipcb4_runstart, _fftipcb4_size
 .global _fftmag_loadstart, _fftmag_runstart, _fftmag_size

是这么改的吗？

好像我的FFT烧到flash里运行有问题

在下边的copy_sections部分有没有也添加相应的代码？

MOVL XAR5,#_fftipcb3_size    ; Store Section Size in XAR5
 MOVL ACC,@XAR5      ; Move Section Size to ACC
 MOVL XAR6,#_fftipcb3_loadstart   ; Store Load Starting Address in XAR6
    MOVL XAR7,#_fftipcb3_runstart   ; Store Run Address in XAR7
    LCR  copy 

添加这些代码后仍不能运行吗？其实不添加这些自定义的段，这些函数会被自动分配到text段，搬移text段就相当于搬移所有代码。

FFT的值得到的都是0

先不要添加FFTipcb3  ALIGN(256)，FFTipcb4 ALIGN(256)，FFTmag这些段，直接使用例程的F281x_nonBIOS_flash.cmd和DSP28xxx_SectionCopy_nonBIOS.asm文件，不用做任何修改。        

你是说直接用官网的例程，不进行FFT算法？

把FFT的相关部分全部去掉，CMD和程序里用到的

 fft.ipcbptr = ipcb;
 fft.magptr = mag;
 fft.init(&fft);

RFFT32_brev(ipcb,ipcb,N);

   fft.calc(&fft);
   fft.split(&fft);
   fft.mag(&fft);都去掉

其他的都可以正常运行

我的意思是参考例程，使用例程的F281x_nonBIOS_flash.cmd和DSP28xxx_SectionCopy_nonBIOS.asm文件，FFT代码照样添加上跟在RAM中运行的一样。
