在做一个项目时,将程序下载到FLASH时出现错误,提示如下
警告文本信息:
"
Warning: This program contains initialized RAM data.
It may run successfully under Code Composer Studio
but not as a standalone system because of this. If
your Flash program requires initialized data in RAM,
you will need to write Flash code to initialize RAM memory.
Erase/Program/Verify Operation succeeded
**** End Erase/Program/Verify Operation. ***
首先我查了CMD文件, 没问题,排查了好久, 最后查到只要将_IQ19toF这句注释掉就能下载无提示并且拔掉仿真器后能运行,如果不注释掉,下载就会出现警告提示,拔掉仿真器后重启DSP无法正常运行.
测试语句如下:
tempiq19 = _IQ19(1.9);
iqtoftemp = _IQ19toF(tempiq19);// 注释掉这一句一切正常.IQmath其他函数运行正常,包括IIR滤波,就这一句加进去DSP就无法运行,仿真器连着时能调试运行.
