烧写方法：将SRAM.cmd替换成FLASH.cmd。一个通用的用于F2812的FLASH.cmd 例子为

重新编译OK！

点击Debug进入调试，点击Load Program...选择刚编译生成的*.out文件进行烧写！然后会出现Erase……

烧写成功！

===============悲剧================

为了调试方便，我设置了点击Debug按钮后自动装载程序，悲剧就在这时发生了！

在一次烧写时由于鼠标抖动，连续点了两次Debug，弹出两个烧写进度条，结果发大了，直接烧写失败，Flash锁死！如下

C28xx: Flash Programmer: Device is locked or not connected. Operation cancelled.
C28xx: Trouble Writing Memory Block at 0x3f7ff6 on Page 0 of Length 0x2 
C28xx: GEL: File: E:\dsp\zx_dsp2000\zx_project_c2000\Debug\zx_project_c2000.out: Load failed.

为吸取经验教训，总结了Flash锁死的可能原因，以后注意这些方面：

（1）由于PC的原因，这里就是这样，中途打断了Flash的烧写过程造成Flash锁死。仿真器在烧写时挂起也会造成Flash锁死，比如有些仿真器速度比较慢，很容易发生挂起的现象。

（2）由于DSP的原因，DSP的电压、时钟等操作条件不对容易造成锁死。

另外，顺便注意DSP与JTAG的上电顺序：

关闭电源开关 ——> JTAG连接DSP ——> DSP连接PC，JTAG连接PC ——> 开启DSP电源开关，给DSP上电

原则：JTAG不能热插拔

================喜剧===============

不过还好，毕竟是一块实验板，Flash锁死但还可以从SRAM跑程序，谢天谢地！
