CCS9.2中编译 TMS320F28377S的flash运行解决delay_us()问题时，碰到 未定义的init_flash的问题，帮看看什么原因

cmd采用是2837xs_flash_link_cpu1_far.cmd，在main.c中增加了memcopy 和initlfash的函数。同时将28335的dsp28335x_memcopy.c复制到工程中，编译时遇到的未定义函数initflash问题，如何 解决。

代码：

InitSysCtrl();

////save to flash
MemCopy(&RamfuncsLoadStart, &RamfuncsLoadEnd, &RamfuncsRunStart);
InitFlash();

问题:

error #10010: errors encountered during linking; "FastTL_DSP28377SCPU1tonghao.out" not built

Green Deng：initflash在系统初始化函数InitSysCtrl();中就有
掉电没有启动的话，你的程序确保烧写进flash了吗？
建议先用你的方法测试一个简单的例程，比如C:\ti\controlSUITE\device_support\F2837xS\v210\F2837xS_examples_Cpu1\gpio_toggle，如果例程没有flash运行的话，那可能是你的操作方法有误，可以把你的步骤发过来看一下
