F2812 串口烧写操作步骤及配置
1.      先安装sdf28xx_v3_3_serial，安装时按照默认路径安装，与CCS3.3安装路径相同；

2.      安装SDFlash 软件：SetupCCSPlatinum_v30329，安装路径与CCS3.3安装路径相同；

3. 编辑sdopts.cfg文件,此文件存放在你所安装的windows的System32目录下
  (1)用记事本的方式打开sdopts.cfg
  (2)在"# End of sdopts.cfg”前加入如下文本:

[EmulatorId=C1]
EmuPortAddr=0xC1
EmuPortMode=RS232
EmuProductName=SERIAL_FLASH
[EmulatorId=C2]
EmuPortAddr=0xC2
EmuPortMode=RS232
EmuProductName=SERIAL_FLASH

[EmulatorId=C3]
EmuPortAddr=0xC3
EmuPortMode=RS232
EmuProductName=SERIAL_FLASH

[EmulatorId=C4]
EmuPortAddr=0xC4
EmuPortMode=RS232
EmuProductName=SERIAL_FLASH

3.      利用串口线连接DSP与PC机；配置F2812为从SCI-A的启动模式，复位时:GPIOF4=0   GPIOF12=0 GPIOF3=1 GPIOF2=1；

4.      打开SDFlash，路径为：C:CCStudio_v3.3specdigsdflashbin下SDFlash.exe，如下图所示。




5.      打开F2812SerialFlash.sdp工程，

路径：C:CCStudio_v3.3specdigsdflashmyprojectssdf28xx_v3_3_serialf2812




6.      打开Project-Settings菜单，对工程进行配置，


_ Driver: This must point to F281xRS232Flash.dll (for F281x devices), to

F280xRS232Flash.dll (for F280x, F2801x, and F2804x), or to

F2833xRS232Flash.dll (for F2833x and F2823x devices).



_ Emulator Address/ID: This is the COM port on your PC that you are using to

connect to the DSP. If COM1, COM2, COM3 and COM4 do not appear as

options, modify the sdopts.cfg file as described previously in step 4.



_ Board file: Leave as ccBrd028x.dat



_ Processor name: Leave as cpu_0





Algorithm File: Use the same algorithm file that you specified on the Erase Tab.

_ Flash Data File: This is the .out file that you want to program into the flash.

_ Timeout: Leave as 0. This option has been superseded by Programming User

Options 4.

_ User Options 1 through 3: Unused.

_ User Options 4: : Program acknowledge retry specifier. After sending the DSP

a packet of data to program into the flash, the PC runs a loop that checks for a

program acknowledge from the DSP. This option controls the maximum number

of times the PC will loop. It can generally be left at the default value of 0.




Algorithm File: Use the same algorithm file that you specified on the Erase Tab.

_ Timeout: Leave as 0.

_ User Options 1 and 2: Unused.

Note: In the JTAG version of SDFlash, these options specify the wait-states for

the OTP and Flash memory to be set before the verify operation starts. The

serial version of SDFlash does not use these options however, and instead the

wait-states remain set to their reset defaults (which are the maximum values).

_ User Options 3 and 4: Unused



8．保存SDFlash工程，


9.DSP上电或复位，以启动SCI-A模式
