Hello！在线调试下（连着仿真器运行）：CLAsin，CLAcos的三角运算正常。程序烧到FLASH中脱开仿真器运行时：三角函数CLAsin，CLAcos运算结果一直是0。但是CLAdiv和CLAsqrt的计算结果都是正确的，程序中添加的库和clasincostable的使用方法如附件。7433.CLA中CLAsin和CLAcos运算问题.pdf

您好,您是说应用程序是在debug模式下运行, 而不是在standalone模式下运行？
如果是Flash config, 您需要确保 CLA 代码和常量加载到了闪存中并复制到 RAM 中。 从您提供的信息来看, .const_CLA 部分直接加载到 RAM 存储器中, 这些值在加电复位后会丢失.
您的问题1：您是说应用程序是在debug模式下运行, 而不是在standalone模式下运行？
回答问题1：CPU1设定在Release模型下运行
您的问题2：如果是Flash config, 您需要确保 CLA 代码和常量加载到了闪存中并复制到 RAM 中。
回答问题2：是Flash 配置，我们已经可以离线跑程序了，实现了其他功能，比如开根号，除法运算等，仅仅三角函数运算不对，这样是否可以说明代码加载到闪存并复制到RAM中是成功的？
CLA的代码和常量加载到闪存并复制到RAM中的代码如下所示：
#if defined(__TI_EABI__)
Cla1Prog : LOAD = FLASHA_M,
RUN = RAMLS0123,
LOAD_START(Cla1funcsLoadStart),
LOAD_END(Cla1funcsLoadEnd),
RUN_START(Cla1funcsRunStart),
LOAD_SIZE(Cla1funcsLoadSize),
PAGE = 0, ALIGN(8)
#else
Cla1Prog : LOAD = FLASHA_M,
RUN = RAMLS0123,
LOAD_START(_Cla1funcsLoadStart),
LOAD_END(_Cla1funcsLoadEnd),
RUN_START(_Cla1funcsRunStart),
LOAD_SIZE(_Cla1funcsLoadSize),
PAGE = 0, ALIGN(8)
#endif
CLA1mathTables : > RAMLS45, PAGE = 1
CLA1mathTables : LOAD = FLASHA_M,
RUN = RAMLS45,
RUN_START(_CLA1mathTablesRunStart),
LOAD_START(_CLA1mathTablesLoadStart),
LOAD_SIZE(_CLA1mathTablesLoadSize),
PAGE = 1
memcpy((uint32_t *)&Cla1funcsRunStart, (uint32_t *)&Cla1funcsLoadStart,(uint32_t)&Cla1funcsLoadSize);
memcpy((uint32_t *)&CLA1mathTablesRunStart, (uint32_t *)&CLA1mathTablesLoadStart,(uint32_t)&CLA1mathTablesLoadSize);
同时给出CPU代码从flash中复制到RAM中的代码如下：
memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (size_t)&RamfuncsLoadSize);
#ifdef __TI_COMPILER_VERSION__
#if __TI_COMPILER_VERSION__ >= 15009000
#if defined(__TI_EABI__)

RUN = RAMGS8_13,

RUN_START(RamfuncsRunStart),
RUN_SIZE(RamfuncsRunSize),
RUN_END(RamfuncsRunEnd),
PAGE = 0, ALIGN(8)
#else
.TI.ramfunc : {} LOAD = FLASHA_M,
RUN = RAMGS8_13,
LOAD_START(_RamfuncsLoadStart),
LOAD_SIZE(_RamfuncsLoadSize),
LOAD_END(_RamfuncsLoadEnd),
RUN_START(_RamfuncsRunStart),
RUN_SIZE(_RamfuncsRunSize),
RUN_END(_RamfuncsRunEnd),
PAGE = 0, ALIGN(8)
#endif
#else

RUN = RAMGS8_13,

回答问题3：您的意思是不是将 .const_cla : > RAMLS45, PAGE = 1 修改如下：
对的，CLA CONST 要加载到flash并复制到 RAM。 请确保添加 memcpy 函数以将内容从flash复制到 RAM。
