1. 一定要下载最新的FLASH烧写插件，可以避免很多奇怪的错误出现，这一点非常重要，本人就是在此问题困扰了一整天。 名称是：
C2000-2[1][1].00-SA-to-UA-TI-FLASH2X.EXE 我使用的产品版本号为2.02.001
2. 下载烧写FLASH配套CMD文件、LIB文件以及起始代码asm文件。 CMD文件名称：DSP281x_Headers_nonBIOS.cmd CMD文件名称：F2812.cmd LIB文件名称：rts2800_ml.lib
ASM文件名称：DSP281x_CodeStartBranch.asm 另外在RAM调试时用以下两个文件： F2812_EzDSP_RAM_lnk.cmd DSP281x_Headers_nonBIOS.cmd
附件给出了2个CMD文件、ASM文件、LIB文件以及C文件。 其中C文件仅仅作为大家参考。
3. 配置C文件
配置好主程序的C文件，才能将FLASH成功烧录，并且将FLASH中的文件拷贝到RAM中运行。 关于C文件的配置。
首先在F2812.CMD文件中，我们可以看到有关于加载FLASH到RAM的内容：
ramfuncs : LOAD = FLASHD, RUN = RAML0,
LOAD_START(_RamfuncsLoadStart), LOAD_END(_RamfuncsLoadEnd), RUN_START(_RamfuncsRunStart), PAGE = 0
以及在C文件中调用FLASH 到RAM的函数memcpy，将它放在系统初始化（InitSystem();）之后即可： InitSystem();
memcpy(&RamfuncsRunStart, &RamfuncsLoadStart,
&RamfuncsLoadEnd - &RamfuncsLoadStart);
Initflash();
所以，我们需要定义所用变量：
extern Uint16 RamfuncsLoadStart; extern Uint16 RamfuncsLoadEnd; extern Uint16 RamfuncsRunStart;
我的这些定义都是：DSP281x_GlobalPrototypes.h 当中,当然，也可以放在其他系统初始化的地方。
Memcpy这个函数应该是rts2800_ml.lib库文件中自带的，不需要我们定义。
关于FLASH的初始化配置Initflash();
我把它放置在Memcpy函数之后。
关于ramfuncs，则在系统初始化中定义即可。如:sysctrl.c中
#pragma CODE_SECTION(InitFlash, \
另外，许多朋友没有注意需要定义自己其他子程序，导致最终运行的主程序还是在FLASH中，比如你需要运行的子程序ABC，则需要定义#pragma CODE_SECTION(ABC, \
烧写成功后的注意事项：
1． 一定要拔除仿真器（JTAG端），给电路板重新上电，方能实现FLASH启动。
2． 注意MP/MC引脚的电压。0为方式MC来作为计算机模式启动，3.3V为方式MP作为微处理器模式启动。
3． 由于GPIO引脚的F4F12F3F2决定了DSP2812的启动顺序，而从FLASH必须要在F4（SCITXDA）为1，而F12F3F2随意的状态下启动。请大家启动前确认F4引脚电压。
